Hi guys, I know this subject has been posted somewhere, but I need an answer ASAP, I tried to google it but cant find an answer. I am an AA exec platinum, I know if i purchaes aa basic, I wont get any of the perks as AA exec.. But if I purchased an Iberia/ BA plane ticket basic ticket from LHR to BCN . It says on there that you wont be able to check in a luggage, unable to choose seat but if I am an emerald, will I be able to check in luggage fr free, choose a seat in advance even my ticket is basic? I dunno the rules of Iberia/BA.. thanks much
