On occasion I have found that I have purchased Y class tickets but I have no idea how I did it. At the time I did not notice any significant price difference from the usual non-Y fares that I'm supposed to buy. When I look for flights I don't seem to have any choice for fare class but there are occasions where I would like to have a Y class ticket.
Any suggestions as to how I would be able to choose from different fare classes? It seems that I can change my profile to look for Y on United.com but I'm supposed to just buy the restricted fares so I would like to be able to see and perhaps buy a full fare economy (if I think I can get away with it.)
Thanks
