nearly new
Easyjet have a mixed fleet and will at some point soon wish to sell on some nearly new 737s. Banning all the oldest planes will firm up the market for nearly new. Sometime I think Easyjet and Ryanair make a lot of money bulk buying planes on the cheap and reselling them after 3-5 years.
I am not so sure that the likes of silverjet will be so happy as they have said they wish to go from 2 to 10 planes in the next 3 years. Most startups have got going with very old planes till they could aford better.
