Australian/UK citizen can't check-in online when leaving Australia
I'm flying Australia - Singapore - UK, and I get this error when I try to check in with my UK passport:
Unable to complete check-in
There are issues with the details entered for the following passengers:
• [redacted passenger name]
If you have a valid ETA, ensure the details entered during check-in match those in the ETA applications before trying again. If the issue persists, please proceed to the airport counter for check-in.
(Error Code: C4212)
And this error when I try to check-in with my Australian passport:
Online check-in is not successful for one or more flights in your itinerary. Proceed to the airport to check in for this flight.
(Error Code: C4220)
Has anyone else had this issue?
I assume the Australia - Singapore leg is checking for an Australia ETA (which my UK passport doesn't have as I can't get one given I'm Australian citizen).
And the I assume the Singapore - UK leg is checking for an UK ETA (which my Australian passport doesn't have as I can't get one given I'm UK citizen).
No issues using my Australian passport to fly from UK - Singapore - Australia, I guess the UK doesn't check exit visas.
It would be great if I could check in the 2 legs with separate passports, but can't seem to do this online. I also can't check in one leg at a time. Means I can't choose my seat!
Very disappointed, I can't be the only UK/Australian citizen flying from Australia to the UK!
