We are arriving from DFW F award ticket at 12:45, BA wants $101 for an award connection to EDI at 8 pm. I said no thanks and bought a BA LHR-EDI ticket for 60 pounds leaving at 3:45; will AA attach the BA reservation so I will not have to mess with our luggage at LHR? On our return I am leaning towards EDI-LGW, bit cheaper, less hassle but we are thinking of buying a London Pass w/travel, 3 days for 91 pounds, but it says it is only partially good from LGW to London (staying at Hilton Trafalgar). We are flying BA to BUD 3 days later from what I read the London Pass will get us to LHR as long as we don't use the express.
