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.
