I don’t think it helps that the BA website /app doesn’t make it clear.

I have a redemption return booking from MAN to New York in ET MAN-LHR (no CE available), and onto NYC in J. Similar on return (J international/ ET domestic).

MMB shows I have lounge access at MAN for outbound, which I wasn’t expecting, and am prepared to be turned away (especially as it’s the day before the long haul flight).

More worryingly, it doesn’t say we have lounge access at LHR between our long haul and domestic return flights. I understand from the rules that we should though. Hopefully not a problem as we have a few hours layover.

edit: apologies for slight hijack of this thread, given it started off talking about bag drop
