In a worst case scenario event, I’m not sure I want to have to evacuate from a smoke filled cabin and have a ladder involved in the process. Seems like a risk for falls/breaks/sprains if you’re trying to peace out of the plane quickly.
I think the only serious answer to this issue is to reduce the number of seats everywhere on all flights, raise prices heavily, and let the high prices and scarcity of seating dissuade people from flying except in extreme cases when it’s worth the money.
Especially finding ways to force businesses to do this, and simply refactor to use teleconferencing, regional offices, etc., and stop having commercial business activities that require flights.
