I find this hard to believe, why then do airlines have such punitive policies for things like changing travel dates and extra fees for checking luggage? Airlines &quot;nickel and dime&quot; travelers now for every minor convenience that was previously included in a fare-  snack foods, in-flight entertainment, emergency aisle seats etc. If nothing really matters besides business class fares then please explain the existence of these insulting and petty practices.<p>Also can you site evidence besides anecdotally that you worked for an airline?
