I already asked a very similar question, but the answer wasn't was I was expecting. Hence this time I am more specific.
How can you recognize a plane from the inside, when you are already sitting as passenger?
In particular, is there a way to understand if you are inside a Boeing or an Airbus based on interior features of the aircraft?
The question is specifically related to the differences in interior features between aircraft built by the two companies. I am not looking for answers such as "check on your ticket", "ask the flight attendant" or "read the evacuation pamphlet".
