Hi ! I am traveling in a couple of days to San Sebastien from Vancouver. My question is on my return flight home my flight is BA 7071 operated by Air Nostrom for Iberia ( EAS to MAD.) If I do online check in do I check in with BA, IB or Air Nostrom? I then connect on to BA operated by AA flight in Madrid to Dallas and then VAncouver. When I check in online (if possible) for first flight from San sebastien will they check me through to Vancouver and provide boarding passes or do I need to check in online also with AA? Or BA? This is all on a single ticket with ticket number beginning with 125. I can access all flights in itinerary with 1 reference number. By the way does anyone know if I get 1 full meal or 2 on a BA long haul overseas economy flight that is 9.5 hrs? There seems to be confusion getting an answer online or even after calling BA directly. Some say 2 and snack others say 1 and 1 fun sized chocolate and others 1 meal no snack.Thanks.
