hello...i searched the forum, however no luck...

My recent flight from Seoul to LAX was a delta flight operated by Korean air. my company buys my tickets and normally I get a Y fare. However this time I recieved a K fare (this is on Delta's milage summary page for me). I checked the amount of money paid for the ticket and saw that the fare prices were similar for my previous Y ticket fares. Is it possible that Delta made a mistake??

Does anyone know how to check or where to check the fare class other than what Delta states? sorry if this is a stupid question....

Thanks
