In most cases the customer flying the plane hardly even notices the exteriors of the plane and 7 out of 10 people will never be able to make out the difference between an A300 and a B767 or an A330 and a B777 for that matter. It is only aviation buffs like us who keep note of all the subtle differences and keep in mind the range, economics, engines etc.
Well my mother never even knows what type of plane she is flying in...only the airline.
...and OK yeah they can only differentiate between a 747 and other types.
So i guess the factors that matter are crew behaviour, comfort, ticket price and of course the flight in general. (if it had been a turbulent flight then they would say it was a bad flight). I have noticed many friends of mine judging the pilot & the a/c by the way the landing is performed!
Well personally for me.(not in any particular order)
1. Looks (yeah they sure do count for me
3. Cabin crew friendliness.
4. width(i prefer wide bodies anyday)
Range, engine capacity does not bother me as i know the plane will be in that route only if it had the required range
Well i guess points 2 and 3 are airline dependent rather than aircraft. Personally i would like to be in economy in a 777 with 2-4-2 seating ...that would be great comfort on a great a/c.
