Status quo is a hard thing to change. Everyone keeps passing the buck at the moment. Needs a high profile name like Sully to advocate for this. The general public mostly won’t care because most don’t fly much, but there are a lot of important people who are frequent flyers who if they feel it may affect them might make a difference. Unfortunately if this is just made out to be a flight crew issue only, nothing will happen.

Does the new A220 have a cabin bleed air system?
