An Airbus order may not be out of the question. Consider that Airbus have had little success in the no-frills market - except JetBlue, but they are an exception and are not as no-frills as others. Coupled with the fact that there are few such large orders in the near future they will be very keen to get this business.. .. .Also how much spares/maintenance commonality is there between the 737-300 and -700? In some respects easyJet is already operating a 2-type fleet.. .. .So if Airbus are that keen for the business they could broker a deal which outweighs the advantages of staying with Boeing.. .. .I don't know how it's looking right now, but it's certainly not a no-brainer decision.
