We've flown in the last few years with Continental, US Airways, Virgin and Aer Lingus, all of whom have 31" seat pitch, and being 6'2, can honestly say I've never had a problem. Even with the seat put back I've still got enough room with my legs right under the seat in front. Dublin, Philly and Newark are all easy to connect in, and certainly in the case of Dublin and Newark - great terminals to spend some time in, if a direct flight is close to same price then its always going to win.
For those who are going to Riverside, you've chosen wisely. Any questions, ask away. As you'll see we've been there a few times now..
