You mentioned in your initial post that you flew BA, should I be concerned as I'm flying on BA to Rome next Wed. as they had the best price and schedule. I too noticed that on some of the other airlines, they were code shared. I thought about it as I am in UA Mileage Plus, but was told that I would not qualify for free checked bag on code share portion of flight, so that is why picked BA since even though they didn't have free checked bag, they offered a better carry on policy regarding the weight, so trying to get by with carry on only.
