Unlike Ryanair, easyJet can defer the Airbus orders to a certain degree. They have chosen not to do this at the moment but what they are doing is replacing the 737 with the Airbus rather than supplementing them. Sadly this means a growth for 2009 of just a few %.
However AH is still predicting a fleet of 200+ aircraft in 2011. The money is there to pay for them and the first of about 20 EZY spec A-320's arrives in Feb 2009.
