So, this is probably dumb but I don't really know the answer, hence the reason I'm leaving it up to the experts here to tell me the info. IF I booked my flight to Santiago on AA and it's operated by LAN, do I still get mileage credit for miles flown? I won't fly LAN if I don't get credit for miles flown so I need to make sure first bc it seems like on such a long flight I should make sure to get my miles flown. Please advise, thanks...
