Which passport rules apply to the ETA?
Your UK ETA is linked to the specific passport you apply with, and it stays valid only while that passport is valid, as set out by the UK Home Office. You must travel on the same passport used in your ETA application.
This linkage is the single most important rule. Therefore, you should always apply with the passport you intend to carry, and never with an old or soon-to-expire document.
In practice, American travelers find the uk eta passport rules straightforward once they have done it once. Therefore, keeping a short note of the steps and your approval details makes any repeat trip even faster.
What happens when you renew your passport?
When you renew your passport, your existing ETA becomes invalid because it is tied to the old passport number. You must apply for a new ETA with your new passport before traveling, even if the old ETA had time remaining.
There is no transfer process between passports. Consequently, frequent travelers should plan to reapply after any renewal, and budget the £20 fee again.
It is worth planning this early rather than at the last minute. As a result, you remove a common source of airport stress and can focus on the trip itself rather than paperwork.

Passport validity for the whole trip
Your passport must be valid for the duration of your stay, and because the ETA expires with the passport, a passport expiring mid-trip effectively ends your authorization. Always check the expiry date before booking.
Renewing early avoids this trap. In addition, applying for the ETA only after confirming a comfortable validity margin prevents needing to redo everything.
Because rules can be updated, it is always sensible to confirm the latest details before you fly. Consequently, a quick check of official guidance close to departure is a smart habit for any visitor.
Are passport-related ETA fees refundable?
ETA fees are generally non-refundable, including when an ETA is wasted because you renewed a passport or applied with the wrong document. The fee covers processing, so it is not returned even if the ETA goes unused.
This makes accuracy essential. As a result, double-checking that you are applying with the correct, valid passport protects you from paying twice unnecessarily.
For families especially, a little organization goes a long way with the uk eta passport rules. Moreover, handling everyone’s authorization together means no traveler is overlooked at check-in.
