I am sure Jet2 have done their market re-search. I seem to remember trying these seats or similar in the front few rows of a 757 about 2 years ago. Maybe someone at Jet 2 can comfirm this.Its not possible to please everyone unless you offer full service business class so they must aim to please the average passenger I suppose.They are definately better than Ryanair with the floppy tray table sticking into your stomach even when you are not over weight.
