My JetBlue Airbus A321LR flight from New York to London–my first-ever daytime eastbound transatlantic light–was pleasant and productive, even in economy class.
Our flight departed from gate 23 and boarded 40 minutes prior to departure.
JetBlue (at least for now) is the most generous US airline when it comes to standard economy class pitch. Instead of 30 inches, you get two inches extra on JetBlue. JetBlue also has an “Even More Space” section in the front of the economy class cabin: 24 seats with 35 inches of legroom.
A great solo travel tip spotted this week on Live and Let's Fly.
