Best overall coach-class airline in North America: JetBlue
Even after the current downgrading, JetBlue's extra legroom still beats any other airline. The de facto charge for a checked bag, at $15 over the minimum fare, is less than on most other airlines. The satellite-based Wi-Fi is free, at slow speeds, and $9 an hour for enough bandwidth to stream movies. And seats in JetBlue's Airbus planes are an inch wider than on any competitors' 737s.
Hope to see you soon on one of my flights!
