If you have a trip booked from JFK or Newark to London this spring, listen up. That “slap on the wrist” for missing travel documents is officially a thing of the past.
While the UK’s Electronic Travel Authorization (ETA) technically launched in early 2025, the British government has officially ended its “grace period.” As of February 25, 2026, the requirement is being strictly enforced at airport gates. If you don’t have your digital approval, you will be denied boarding before you even leave the tri-state area.
What exactly is the UK ETA?
Think of the ETA as the UK’s version of the U.S. Electronic System for Travel Authorization (ESTA). It’s a digital permission—not a visa—required for travelers from 85 countries (including the U.S.) who are visiting for:
- Tourism
- Visiting family or friends
- Business trips
- Short-term study (up to 6 months)
- Transiting through the UK (even if you’re just switching planes at Heathrow)

The “No Permission, No Travel” Rule
Previously, carriers were given some discretion to allow travelers through without an ETA while the system was new. However, as of late last month, the UK Home Office has switched to a “No Permission, No Travel” policy.
Pro-Tip: This applies to dual citizens too. If you hold both U.S. and British citizenship, you can no longer use your U.S. passport to enter the UK without an ETA; you must travel on your British passport or show a Certificate of Entitlement.
The Quick Facts: Cost, Speed, & Validity
- The Cost: Currently £16 (~$21 USD). Note: The UK government has signaled this will likely increase to £20 later this year
- The Turnaround: Most applications are approved in minutes, but the official advice is to apply at least 3 working days before your flight just in case of a manual review
- The Validity: Once approved, your ETA is valid for two years (or until your passport expires) and allows for multiple entries

How to Apply
The easiest way to get your approval is through the UK ETA app (available on the App Store and Google Play). You’ll need to scan your passport, take a “liveness” photo of your face, and answer a few quick security questions.
If you prefer the desktop version, you can apply directly via the official GOV.UK portal.
Warning: Be wary of third-party scam websites charging extra fees. Only use the official government app or website to ensure your data is secure and your ETA is valid.
Planning a trip soon? Make sure to double-check your passport’s expiration date alongside your ETA, as the authorization is digitally linked to that specific document. Check out a guide on applying for the UK ETA below:
