I'm with DollarBill on the sleeping thing. I'll sleep in economy no problem. I've slept in cockpit jumpseats (got woken up by turbulence once and was extremely confused) and the fold down seats cabin crew use during take off and landing, and I can assure you those are far less comfortable than an economy seat, even an FR one! Couldn't walk right for weeks.....
Connecting from CFN to GLA, all depends on the times of the T/A flights, and where they are going, who with etc. I can't praise JetBlue enough in comparison to the U.S. legacies, who are all woeful, especially AA. DL are the best of a bad bunch in my experience.
