Do you have a source for this? From what I can find, the up-and-coming A220 has the same design[0] for the overwing exit as the 737, which was added in the 737N

  The issue is probably the other doors. The 737 doesn't have any sort of gas assist to help in opening the main doors in an emergency. https://www.airliners.net/forum/viewtopic.php?t=761051 https://www.airliners.net/forum/viewtopic.php?t=761051

  Actually I misremembered. It was not the plug style that causes issues but the size of the exit. The change from the throw out door to the hinge version in the NG is apparently a change they made to satisfy JAA: https://www.flightglobal.com/news/articles/boeing-details-emergency-exit-on-new-737-21088/ https://www.flightglobal.com/news/articles/boeing-details-em... Oddly enough that news bulletin says it's still a plug door which it clearly is not in the final design. Overall the root cause I believe is generally weight of doors and evacuation time. I had a few conversations about this around the time the second accident happened and grandfather rights were brought up by people from the industry I talked to as an expensive problem for a new type rating.

  The A220 is in service today, on Delta. I flew one this afternoon.
