We're pretty much stuck with AA. Love their trick that lets you get to the book your seat page and low and behold, the only seats available are upgrades! You do get a separate receipt for that payment, which I always carry just in case.
Last trip a week or so ago showed every seat filled, but was 3/4 full
Elaine - do you fly out of Hartford or JFK. We gave up trying to go from Hartford. Just JFK and can almost always get a direct on JB or Delta. Other option would be connection to Westchester which sometimes works great. Other times not so much!!!!
