We changed them from a flat 4000hrs jet to an alternative of 2500hrs on specific types that were useful (basically Boeings and Airbuses) specifically to try and get the types of younger guys at the likes of easyJet, Ryanair and Jet2 who had shown as being good value.
Have a look at the recruitment thread here- still plenty of 4000hr guys applying- the company would prefer someone with a few less hours from a more relevant operation.
