Sometimes competition with lower costs lead to a race to the bottom in quality where you cannot even buy anything of the former quality even at higher prices. You will see carriers nickel and dime you everything that was previously included.
This already happens, every time I sit through United's forced-ads talking about how "I saved up to $100 on checked bag fees". (All to promote their crappy Chase partnership.) Still, pretty cheeky to rub the baggage fees in people's faces, I think.
Or, United not carrying amaretto on some flights, or having the nerve to charge $6 a drink for it in the lounges.'
