SCANDIC
What's that based on??!! The paintwork??!!
Jet2's 757 fleet age is varied with some models built in the mid to late 90's. All Jet2 aircraft have recently had new interiors fitted over the last few years. I wasn't overly keen at first but passengers often comment that they find them more comfortable and roomy than some of jet2's competitors.
Have a look at the age of Monarch's remaining 757's. Perhaps you're basing your assumption on engineering? Jet2 757's are not quite at the 'need scrapping' stage as you put it. It's sad to say that the performance of the 757 hasn't nearly been matched by any new 737 or A320 variant.
It's true that the summer season plus the age of the avionics of the aircraft can take its toll but I've seen just as many Thomas Cook or Thomson 757's with some tech issues this summer.
I'm not having a pop at you, I just find your comments a little odd?!
