Yes, the JL website is quite annoying. What is this with having to pick every time your language and location? Anyway, I've always had some kind of trouble accessing JL flight reservations using AA ticket numbers. It usually works for me as long as the flight is not the codeshare, but the JL flight number.

This time, a new result. Recently bought a ticket on the JL website (JL ticket number) that included both a JL flight and an AA flight (AA flight number). All good on the website, could access the reservation, pick seats, and order special meals. Called AA to apply a SWU to the AA leg, so the ticket got reissued to AA stock. Now, bupkus access, with the JL PNR, the AA ticket number, etc.

The message I get is this one:

Error: We sincerely apologize for the inconvenience.
The schedule of your reserved flight has been changed. However, reservation details cannot be displayed due to the following reasons:
• Reservation includes an upgrade
• Connecting flight must be changed due to a flight time change
• Flight route or seat class has changed

I think everything is OK (my seat and meal choice selections have been preserved), and I can see the flights (but not the JL seats) on the AA app. But is it possible that the reissue mucked up the seat assignments and meal choice?
