Clearly a money grab by the Canadian Government!

2023 I think! In her case it was a U

I hold UK and US dual - just had an issue where I have a tight offline connection and little time to do a passport verify (WN to AA). Normally I don't do an ETA and just show the agent my UK passport, with AA and others checking API status for Home Office ETA flag this is now a problem.

Based on this offline connection, I was risking being a NO SHOW for check in. So I applied for an ETA on my US passport, got approved. AA check in still did not work - 10 min later it did and boarding passes issued. Really wish ALL airlines allowed you to enter a second a passport.

For those asking why risk it: Last minute trip due to a family emergency, so had little other choices with less flight availability - low risk missing the connection offline

Thanks for the data point that you were granted an ETA on a foreign passport despite being a British citizen. Have you ever submitted your US passport (or copies) to HMPO when renewing your UK passport?

Does AA not allow you to check in online without being logged in to your profile?

Yes; however, when checking in while not logged in to the AAdvantage account, one has to enter the PNR. That, in turn, pulls up their profile including the passport information. I would think that depending on which passport they are going to use to enter their destination, it is possible change the passport information in their AAdvantage profile prior to checking in to a flight.

For the UK - US dual citizen, travelling from the US to the UK, this is getting tricky, creating a conflicting set of requirements:

1. As US citizen, you have to leave the US using your US passport, so that passport details have to be on your boarding pass
2. As UK citizen, you have to have your UK passport on the booking during check-in, to avoid IDB
3. A UK citizen, technically, is not allowed to obtain ETA, unless they lie during the application process

When the ETIAS system is up, this will create a similar problem for the UE - UK dual citizens.

No. You have to "bear" a US passport. No requirements to have the data on your PNR.

The US government does not care about a US citizen having mismatched entry/exit records.

The US government does not have the capacity to detain an apparent foreigner leaving the US but having no entry records.

Oh OK, I stand corrected. Although, I know a dual citizen who was questioned, when leaving the US with the non-US passport.

The US does not have formal immigration exit controls. The final manifest, including the passenger information, is transmitted by the airline to the CBP via APIS.

In hundreds of international departures from the US, I have never seen any passport details on my boarding passes, not even when decoding the QR or bar codes. Yes, the passport information is in the PNR.

I stand by my earlier advice
