I got to fly in quite a few different intercontinental airliners over the years. My perception of each:
Boeing 747 - fast, seating a bit cramped, average noise levels.
Boeing 777 - reasonably fast, very noisy in most of the cabin.
Airbus 330 - slow, but quieter than B777.
Airbus 340 - slow, lumbering takeoff and glacial climb (especially -300 version), quieter than A330.
MD-11 - reasonably fast, very quiet, comfy. My favorite. Perhaps Thai airlines had better insulation?
Sadly I never travelled in a Tristar or the newer Airbus planes or Boeing 787.
I pretty much agree Carnot.
747 Isn't everything cramped to a greater or lesser degree? Otherwise OK. Even flew on that ghastly red aboriginal thing painted with crocodiles and whatever. Thankfully it was dark and didn't see the outside at Heathrow only when we arrived at Tullamarine.
777 definitely noisier than 747 - and just about everything else.
A340 OK but appears 'poky' after 747 or 777.
Never travelled on an MD11 only on DC10 and loved it.
Lockheed Electra beautiful - across the Tasman anyway.
Fokker 70 and 100 plus Boeing 717 very comfortable (2+3 seats). I think that some Australian airlines are now the major users of these frames and still buying available secondhand ones when they can.
Looking forward to an A350.
Adding up the miles a toss up between A340 and 777 as to the most miles flown on a type.
I miss the individual air vents even if only to direct them onto the head's of passengers in front who put their seats back too far.
