Longest flight I had in an airliner was from amsterdam to london gatwick. It is also my only trip in an airliner as to date. So my experiences with airlines is rather small...
I did however flew an hour or so in the Chech republic. Just a round trip around the beautifll countryside. it was in an very old plane, there where some holes in the fuselage where the calbes went out to the control surfaces and you could look tru them straight outside
that was my first flight.
