Where did you see that? My understanding is that it's an optional plug door that's used to assist with interior installation. Once the interior is done, it's bolted shut and interior paneling is installed over top. From the inside, you can't tell it's there.
- paranoidrobot 3y agoMy source is [1], specifically at about 5:05. Alaskan airlines chose a 178 passenger configuration for their 737-9, and so are not required to have a mid-cabin exit door. Lion Air's chosen to go with a 221 passenger configuration, and so are required to have an operating door. Obviously changing up the number of seats isn't done on-demand, you'd need to go for a refit/maintenance cycles. But if Alaskan decided to change density, or sold the aircraft to someone else who decided to change density - then they could go and do this.

- deelowe 3y agoAhh. Well, in the case of the Alaska flight, it's a plug door and not used as an exit. It's pinned in place with large pin that has a bolt, a castle nut and cotter pin which lock the pin.
