Having said all of that if you really have to do it, the following would probably work if you can make it happen:
- get a separate reservation in A on the relevant AA flight (don't link it to a ticket number or anything - just get AA or a TA to make a reservation - and don't cancel the BA reservation)
- get the reservations for all the flights after the BA BOS-LHR split into a separate PNR - you will probably need a tame TA to make new reservations for you
- just check in at BOS at the AA F desk as normal, saying that you have moved your reservation to the AA flight - the check-in agent will see a ticket that says "Valid on AA/BA/CX etc." and a reservation on the AA flight; should be no problem</font>
Currently, my only reservations are for BOS-LHR, connecting to LHR-SIN, both on BA. Suppose I walked up to the AA ticket counter at Logan and asked if they could switch me to the AA BOS-LHR flight. (As of today, it's wide open in F.) The AA flight would make my BA connection illegal, so I also would ask them to switch me to BA's flight to SIN that leaves 40 minutes later (interesting that BA has two LHR-SIN flights within 40 minutes of each other). If I got the AA agent to issue boarding passes for both flights, would I be in the clear? Again, not a big deal, but just curious.
