The carrot of an early command at Easyjet has been a major card for several years now. However, once Gatwick has fully converted to the bus and the gaps on the 737 fleet filled the number of Commands in the UK will reduce significantly probably as soon as the end of this year.
The UK Easyjet operation has pretty much reached its limit and the majority of future expansion will be into France and Germany. There will of course be the shuffle of aircraft and personnel around the UK bases and natural attrition of crew that will have to be replaced with fresh blood, but this will be no where near the requirement that we have seen in recent years.
There will still be a large demand for pilots but the lions share will be for European bases on the Airbus and not in the UK on the 737.
