I'm currently in London, about to fly to Barcelona this afternoon to begin an ex-EU ticket to the US tomorrow morning. I'm flying BCN-PHL-DCA and then a return from JFK-LHR-MXP in a couple of months. I'm a US citizen with a US passport and an AA EP.

I purchased a ticket through Amextravel (I know...). It's a 125- ticket. The opening BCN-PHL leg is a BA flight operated by AA, as is the JFK-LHR return. The PHL-DCA leg is an AA flight with an AA flight number. The LHR-MXP leg is irrelevant for now.

I noticed at one point that I have one BA record locator and two different AA record locators for this flight. One (let's call it AAAAAA) has BCN-PHL and the two return legs, but no PHL-DCA leg. The other (BBBBBB) has all four legs. I contacted AA about this and was told that it wasn't an issue, that it was just a product of their backend and didn't affect my booking in any way.

When I go to my BA record locator, I can enter in my contact tracing info, etc, with no issues. Beginning the checkin process with BA forwards me to AA, but I'm sent to record locator AAAAAA, with the missing PHL-DCA leg. I can check in for this flight, but there's no PHL-DCA leg listed and no boarding pass for that flight.

If I go to to the AA site and try to check in under BBBBBB, I'm prompted to enter contact tracing info. When I do that, there's no link to continue my checkin, but when I return to that record locator to check back in, I'm asked to enter contact tracing info again on a loop. The app also throws errors.

I'm concerned that the outstation at BCN won't be able to resolve this tomorrow morning, and that the rest of my itinerary will be cancelled because I haven't checked in or flown for BCN-PHL on BBBBBB. If I go to the Gold desk at LHR early today for my flight, do you think they would be likely to resolve this?
