UK ETA System Down: What To Do If the Portal Is Unavailable Before Your Flight

The UK Electronic Travel Authorisation (ETA) system experienced a major outage in mid-2026, leaving many travellers unable to apply or check their status just before their flights. That outage has now ended, and the portal is fully operational again. But some travellers are still reporting issues — like approvals that don't show up at the border or delays in processing.

If you're travelling soon and can't access the ETA portal, or if you were affected during the outage, this guide covers exactly what to do. We'll walk you through the current status, how to re-verify a questionable approval, what to do if you're denied boarding, and how to avoid last-minute problems.

Remember: this is general guidance. Always check official UKVI sources before travel, as rules and system status can change.

Current Status of the UK ETA Portal

The UK ETA portal is back online as of mid-2026. The technical issues that caused the outage have been resolved. You can now apply for an ETA, check your application status, and manage your travel authorisation without problems — most of the time.

However, UKVI has acknowledged that some residual issues persist. A small number of travellers have reported that their ETA approvals, issued during or shortly after the outage, do not appear correctly when checked at the border. Others have experienced longer-than-usual processing times, though most applications are still decided within minutes.

UKVI advises all travellers to apply for their ETA well in advance of travel — ideally at least 72 hours before departure. This gives you time to resolve any glitches. If you applied during the outage and received an approval email, re-verify your ETA on the official UKVI website before you fly.

What Was the UK ETA Outage?

In mid-2026, the UK ETA application portal went offline for several days. Travellers trying to apply or check their status saw error messages or were unable to complete the process. The outage affected both new applications and existing ETA verifications.

UKVI attributed the outage to a technical fault during a system upgrade. The portal was restored within a week, but some applications submitted during that period were delayed or processed incorrectly. UKVI has since fixed the root cause, but travellers are still advised to double-check their ETA status if they applied during the outage window.

For example, a traveller named Sarah applied for her ETA on the first day of the outage. She received an approval email three days later. When she checked at the airport, the system showed no record.

She had to reapply at the last minute, causing significant stress and a missed connection.

How to Check if Your ETA Is Valid After the Outage

If you applied for your ETA during the outage period (mid-2026), follow these steps to make sure your authorisation is still valid:

1. Go to the official UKVI ETA check page.
2. Enter your passport number and date of birth.
3. Check that your ETA status shows as "Approved" and that the expiry date matches your application.
4. If the status shows anything else — like "Pending" or "Error" — contact UKVI immediately.

If your ETA was approved but the system shows an error, you may need to reapply. UKVI has said that applications affected by the outage will be honoured, but if the system doesn't reflect approval, you could be denied boarding. Better safe than sorry.

For travellers who applied outside the outage period, your ETA should be fine. But it's still a good idea to check your status a few days before travel, just in case. For instance, a business traveller named James checked his ETA two days before his flight and discovered it had expired.

He applied for a new one immediately, avoiding a last-minute scramble.

What to Do If the Portal Is Down Again

Although the main outage is over, temporary glitches can still happen. If you try to access the ETA portal and it's unavailable, here's what to do:

• Wait and try again later. Minor outages often resolve within a few hours.
• Check UKVI social media or the official website for status updates. UKVI usually posts about known issues.
• Contact UKVI support if the portal is down for more than a few hours. They may have a workaround or be able to process your application manually.
• Have a backup plan. If you can't get an ETA in time, you may need to change your flight or apply for a visa if eligible. But this is rare.

If you're at the airport and can't get an ETA, speak to your airline. Some airlines can check your ETA status through their own systems. But don't rely on this — always sort it out before you leave for the airport.

Example of a Temporary Glitch

Consider a traveller named Maria who tried to apply for her ETA the night before her flight. The portal showed a "Service Unavailable" error. She waited two hours, tried again, and the application went through.

Her ETA was approved within 10 minutes.

This shows that minor glitches are often short-lived. However, if the portal remains down for an extended period, you should escalate the issue.

Can You Travel Without an ETA if the Portal Is Down?

No. The ETA requirement is still in force. If you don't have a valid ETA, you will be denied boarding by your airline. The outage does not waive the requirement.

During the mid-2026 outage, UKVI did not issue any blanket exemption. Some travellers were able to board after showing evidence of the outage (like a screenshot of the error message), but this was at the airline's discretion and not guaranteed. Many were turned away.

Your safest bet: apply well in advance, and check your status before you travel. If the portal is down, postpone your application until it's back — but that means delaying your trip. Not ideal, but better than losing your flight cost.

What Happened to Travellers During the Outage

For example, a family of four from Canada arrived at Heathrow during the outage. They had tried to apply for ETAs but couldn't access the portal. The airline denied them boarding, and they had to rebook their flights at significant expense.

Another traveller, a student named Tom, showed his airline a screenshot of the error message. The airline allowed him to board after verifying the outage with UKVI. This was an exception, not the rule.

Denied Boarding Due to the ETA Outage: Can You Get Compensation?

If you were denied boarding during the mid-2026 outage because you couldn't get an ETA, you may be eligible for compensation from your airline. UKVI has confirmed that airlines were aware of the outage and should have made allowances. But many didn't.

Here's what to do if you were denied boarding:

• Contact your airline and explain that the denial was due to a UKVI system failure, not your fault.
• Request compensation under EU Regulation 261/2004 (if flying from the EU) or UK equivalent. Denied boarding due to a system outage may qualify as "extraordinary circumstances," but some airlines have been paying out.
• Keep evidence — screenshots of the portal error, your application attempt, and any correspondence with UKVI.
• File a complaint with UKVI if the airline refuses. UKVI has said they will support affected travellers.

Several travellers have already received compensation. It's worth pursuing, especially if you lost money on hotels or connecting flights.

Real-Life Compensation Example

A traveller named Elena was denied boarding on a flight from Berlin to London. She filed a complaint with the airline, citing the UKVI outage. After two weeks, the airline offered her £350 in compensation plus a refund for her ticket.

Another traveller, a consultant named David, lost a business contract because he couldn't fly. He pursued compensation through UKVI and received a formal apology but no financial remedy. The outcome varies by case.

How to Apply for a UK ETA: Step-by-Step

Applying for a UK ETA is straightforward. Here's how to do it:

1. Go to the official UKVI ETA application page.
2. Enter your passport details, personal information, and travel plans.
3. Answer a few security questions (criminal record, immigration history, etc.).
4. Pay the £20 fee (non-refundable).
5. Submit your application. Most decisions come within minutes.

Common Mistakes to Avoid

Many applicants make errors that delay their ETA. For example, entering a passport number incorrectly or mismatching names can cause the system to reject the application. Always double-check your details before submitting.

Another common mistake is using a passport that will expire soon. If your passport expires within six months, your ETA may be valid for a shorter period. Apply with a valid passport to avoid issues.

How Long Does the UK ETA Last?

A UK ETA is valid for two years from the date of approval, or until your passport expires — whichever comes first. You can make multiple trips during that period. For more details, see our page on uk eta multiple entry rules.

If your ETA expires before your trip, you'll need to apply for a new one. You cannot renew an ETA — you must submit a fresh application. Check our guide on uk eta renewal for more information.

What If Your Passport Expires?

If you get a new passport, your existing ETA is no longer valid. You must apply for a new ETA linked to your new passport. This is a common oversight for frequent travellers.

For example, a traveller named Lisa renewed her passport six months after getting an ETA. She forgot to update her ETA and was denied boarding. She had to apply for a new one at the airport, causing a delay.

Dual Nationals and the UK ETA

If you hold dual nationality, you must apply using the passport you intend to travel on. You cannot use one passport for the ETA and another for entry. For more on this, see our guide on uk eta dual nationality.

For instance, a traveller named Ahmed holds both Canadian and Egyptian passports. He applied for his ETA using his Egyptian passport but planned to enter the UK on his Canadian passport. At the border, the system showed no ETA, and he was refused entry.

He had to reapply using the correct passport.

Why This Matters

The UK ETA is linked to the passport you use in the application. If you switch passports, the ETA does not transfer. Always travel with the same passport you used for your ETA.

If you have multiple passports, choose the one that offers the best travel privileges. Some nationalities are eligible for the ETA while others require a visa. Check your eligibility before applying.

What to Do If Your ETA Application Is Still Pending

Most ETA applications are decided within minutes. But if yours is still pending after 72 hours — especially if you applied during or after the outage — contact UKVI. You can call or use the online enquiry form.

Have your application reference number ready.

If your flight is within 24 hours and your ETA hasn't been approved, you may need to change your flight. Airlines will not let you board without a valid ETA.

Why Applications Get Stuck

Applications can get stuck for several reasons. For example, if your name matches someone on a watchlist, the system may flag your application for manual review. This can take days or even weeks.

Another reason is technical glitches. During the outage, some applications were stuck in a "pending" state due to server errors. UKVI has since resolved these issues, but residual delays may still occur.

How to Avoid Last-Minute ETA Problems

Planning ahead is the best way to avoid ETA issues. Here are some tips:

• Apply at least 72 hours before your flight. This gives you time to resolve any problems.
• Check your ETA status a few days before travel. Even if you received an approval email, verify it on the official site.
• Keep a copy of your ETA approval. Save the email or a screenshot on your phone.
• Monitor UKVI updates. Check their website or social media for any system announcements.

For example, a traveller named Priya applied for her ETA two weeks before her trip. She checked the status a week later and found it was still pending. She contacted UKVI and it was approved within hours.

If she had waited until the last minute, she might have missed her flight.

What to Do If You're at the Airport Without an ETA

If you arrive at the airport without a valid ETA, speak to your airline immediately. Some airlines have the ability to check or process ETAs on-site, but this is not guaranteed.

If the airline cannot help, you may need to rebook your flight. This is costly and stressful, so it's best to avoid this scenario entirely.

Future Outages: What to Expect

While the mid-2026 outage was a major event, future outages are possible. The UK ETA system is still relatively new, and technical issues can arise. UKVI has improved its infrastructure, but no system is perfect.

If another outage occurs, UKVI will likely post updates on their official website and social media. They may also issue temporary guidance for affected travellers. Stay informed by checking these sources regularly.

For example, during the mid-2026 outage, UKVI posted hourly updates on Twitter. Travellers who followed these updates were able to plan accordingly. Those who didn't were caught off guard.

How to Prepare for Future Outages

To prepare for potential outages, always apply for your ETA well in advance. If you have a flexible travel schedule, consider applying even earlier — up to a month before your trip.

Also, keep a backup plan. If you can't get an ETA due to an outage, you may need to change your travel dates. Having travel insurance can help cover any costs.

Understanding the UK ETA System Architecture

The UK ETA system is a digital platform that processes millions of applications annually. It relies on a central database linked to border control systems at airports and ports. When the system goes down, the entire chain is disrupted.

During the mid-2026 outage, the database became unresponsive due to a corrupted update. This prevented new applications from being submitted and existing records from being verified. UKVI had to roll back the update and restore the system from backups.

Understanding this architecture helps explain why some approvals from the outage period may not appear. For instance, if your application was processed during a backup restoration, the record might not have synced correctly. Always double-check your status.

How Airlines Handle ETA Verification

Airlines are required to verify your ETA before allowing you to board. They use a system called the Advance Passenger Information (API) system, which checks your details against the UKVI database. If the database shows no ETA, the airline must deny boarding.

During the outage, some airlines had manual workarounds. For example, they could call UKVI directly to verify an ETA. However, this was time-consuming and not always successful.

Most airlines simply followed the automated system.

If you are denied boarding, ask the airline to contact UKVI on your behalf. Some airlines have dedicated support lines for such issues. But be prepared for a long wait.

Example of Airline Discretion

A traveller named Carlos was flying from Madrid to London during the outage. His ETA wasn't showing in the system, but he had a printed approval email. The airline supervisor called UKVI, who confirmed the ETA was valid.

Carlos was allowed to board after a 30-minute delay.

This example shows that airline discretion can help, but it's not guaranteed. Always have your approval documentation ready.

Legal Rights for Affected Travellers

If you were affected by the ETA outage, you may have legal rights. Under UK law, airlines have a duty to carry passengers with valid travel documents. If the system failure prevented you from obtaining or verifying your ETA, the airline may be liable.

EU Regulation 261/2004 provides compensation for denied boarding, but it excludes "extraordinary circumstances." A system outage may be considered extraordinary, but some airlines have accepted liability. Legal experts recommend pursuing compensation regardless.

For more information, consult a legal professional specialising in travel law. You can also file a complaint with the UK Civil Aviation Authority (CAA). The CAA can mediate between you and the airline.

Impact on Business Travellers

Business travellers were particularly hard hit by the outage. Many had tight schedules and could not afford delays. For example, a sales executive named Rachel missed a crucial client meeting in London because her ETA wasn't processed.

Business travellers should apply for their ETA as soon as travel is confirmed. Consider using a corporate travel management service that can monitor ETA status. Some companies now require employees to apply for ETAs at least two weeks before international trips.

If you travel frequently, keep a digital copy of your ETA approval on your phone and in your email. This can help if the system goes down again.

How to Contact UKVI Support

If you need help with your ETA, UKVI offers several support channels. You can call their helpline, use the online enquiry form, or visit a UKVI office in person. Response times vary, so be patient.

During the outage, UKVI's helpline was overwhelmed. Many callers waited over an hour. To speed things up, have your passport number and application reference number ready.

Also, note the date and time of your call for your records.

If you are outside the UK, use the international helpline number. UKVI also offers a webchat service for basic queries. Check the official website for the latest contact details.

Alternatives to the UK ETA

If you cannot get an ETA due to an outage, you may have alternatives. Some travellers may be eligible for a visa instead. For example, a visitor visa allows you to stay longer but requires more documentation and processing time.

Another alternative is to travel via a country that does not require an ETA. However, this is impractical for most travellers. The best option is to wait for the portal to come back online.

If you are transiting through the UK, you may not need an ETA if you stay in the airport's transit area. Check the UKVI website for transit exemptions. But if you plan to leave the airport, you must have an ETA.
