I book F because I want a seat that I can actually comfortably sit in and depending on the time of day and my jetlag can either work or nap. But then again I've always been the opinion that in-flight food is better to be avoided if you have a chance, especially so on US domestic flights. But hey, more upgrade space or buyup space for me if more people thing like you. In that twisted sense I'm all for these changes by UA
You are exactly the type of customer United prefers =). They can charge more and give less! Might as well fly Spirit or Frontier then! Some people actually spend more and want a premium product. United though isn't much different than Spirirt in F and its Big Front Seat on many routes.
