Jet2 fleet looks OK until you see something new parked next to it, the same is true of the bmibaby fleet.
I don't think pax care too much unless it translates in to tech delays, if you can keep the paint clean and the interior tidy then you have an ok product.
The Ryanair aircraft will use the same fuel to the Med but can carry an extra 37 pax and knock at least 15-20 minutes off the flight time.
Pax numbers for both will make interesting reading over the next six months
