Q, Y, W, P ... And so on, what does all the class describing letters mean ? Isn't it enough with just F for first B for business and E for economy ? As far as I have noticed there are at least ten different letters in use, what do they mean and is at the same for every company ? I've heard that some letters are used together with discounted prices and such but it sounds a little bit wired. Anybody have a clue ?
