On one of my recent jaunts from Toronto to New York, I was able to experience one of WestJet’s freshly refitted 737 cabins. These cabins have a much cleaner look compared to the traditional premium cabin (3 seats with the middle blocked off).
Not only are the seats more comfortable, but they are wider since there are only two seats. No more worrying about tipping over the spacer that turns the middle-seat into a shared table! Add to that a universal plug as well as a USB charger and ample leg-room (without entertainment boxes taking up space), you don’t have to worry about your carry-on fitting.
