I havent a clue how my next flights are going to credit.

Got BA from MAN-LHR-DUB with my BAC number in there.
Would like to credit to AY, even though earnings might be minimal, but dont want to end up back in group 5, 9 or whatever. Suppose the flights arent too long, so if i get my hand baggage on board, that's fine regardless of where i sit etc. If it gets checked in for free, shouldn't be an issue either as staying over in Dublin anyway.
Flashing my gold card will get me lounge access anyway, and no security as such at LHR for CTA to domestic?


Changed from my original AY DUB-HEL-SIN to:
DUB-LHR with BA (Y) due to time changes.
Then QF PE (W) to SIN.

Return flights are AY PE SIN-HEL (P), and I paid about £86 to upgrade into business from HEL-DUB (U). Probably not worth it, but hey.

Do have my AY Basic number and my BAC number in the BA / QF part of the booking. AY number only for the return.
Not sure why the BA number is there as it was replaced by the AY number in the system.
Hopefully things credit to AY.
