The Main difference between Boeing and Airbus is that Airbus ia 'cheaper'...Not built to Boeing strengths(lighter) for more performance...But as a friend who has recently 'checked' out on the 757 said compared to the 320/330"it's a nice simple aircraft"(circ1980)
When I was asked how I liked the 320,after flying the 727 for 10 years,I could only reply"the 727 was stronger,I don't think the 320 will'last'as long as a 727...But any aircraft that can give me a single engine autoland in WOXOF conditions is'nt all bad"
Cheers
