Is there something with this approach that doesn't work?
This is how it’s supposed to go. However, I’ve seen that some OLCI interfaces not work properly.
My sister has both US and EU passports, on AA.com I tried using the EU passport departing the US for Europe. It would not let me proceed without selecting if she has either an ESTA, visa or green card and entering respective data. I ended up pushing the OLCI thru with her US passport info.
My hope is that a solution will come for these situations if they ever become actual issues given how ETIAS seems to have the same implementation timeline as Real ID…
