The ill fated US soda charge and the UA BOB for International Y were ideas implemented when the airlines were losing billions. Through consolidation, rationalization and better capacity management the airlines are now making billions and should continue to do so save for something extraordinary such as soaring oil prices. Should airlines try to compete somewhat on amenities? If not, why not go the entire ultra lcc in Y and be done with it.

The fact is that more business flyers fly on AA, UA, DL and WN than Spirit, Allegiant or Frontier. Most of them are not EXP type flyers. For the exception of those that supplement their business travel with personal flying most are likely in the lower or mid tier levels and accordingly probably spending most of their time in Y. Why wouldn't AA try to do some little things to retain them. Hell, DL still gives out the little snack bags and from time to time a friendly FA will give you all three snacks.
