Airlines are different: my airline uses F A Z // J C D I U // W T P // Y B H K M R V N L S Q O G X E for selling classes in order highest/lowest!
This is interesting stuff to the average punter like meself....
I'm guessing that all airlines have some kind of commonality / pecking order--- F= first class or best. Y used to = 'tourist class' I believe (or bottom of the pile).
Quite often I buy a ticket based on where and when and have no idea what merits it has. Are there any rough guides as to what is good and not?
