Sailing, I don't dispute that you heard that, but it does not match the numbers Delta reported to the DOT BTS. According to those numbers, the 757 is about 15% less to operate and the -300 is the most efficient airplane in the fleet.
You are correct the airplane is simply getting old. The construction of the fuselage cycles out. Maybe maintenance is the killer.
The 757 is a clearly superior airplane, which is easier to fly and enjoys more "big airplane" systems. Unless they change that L1 door, closet, galley choke point, it will be difficult to have any efficiencies as far as turn times go.
I like some of Boeing's big, flat and fat dual aisle designs. The A330 and 767 are so much easier to get on and off of. Even the baby bus' lager aisle width allows folks to drag bags, making it easier to exit.
End of the day, I'm thrilled we are investing in our narrow body fleet. Job security is bottom line.

Interesting that someone noticed 20 717s are no longer for sale on Boeing.com.

Not just derated. Even full power it can be a runway hog. I often ask for full length in EWR instead of 22R at W. All the widebodies are taking the intersection and my little 737 needs full length- all 12,000'. The company likes the derated power for obvious reasons and the plane is often good at W with a derated thrust, but why drag the gear through the grass at the departure end? I'll do full power and/or full length to rotate on the numbers on the other end (with the displaced threshold). It all depends on the weight and conditions. We often use the longest runway, full power, and/or bleeds off in the 900ER. I do a lot of SFO and request 28 for departure because we can't do the 1's.
