Oh, how I wish I could know what F is like. To me, even J is a distant dream 99.99999% of the time. Being a government employee (U.S.), I have to fly whatever is the cheapest flights - and can be ticketed no more than 72 hours in advance, so never get even a good seat in Y. The OP makes me dream of how it would be to get jaded on J due to fabulous in F.
