Preference. What you would like, not necessarily what you will get. It's like saying, yes I will try to accommodate what you want, but what I want always takes priority. It does sound good, but so do lots of things. This preferential bidding system is not up and running anywhere else in easyJet but I believe its setup is being discussed. Be wary of putting faith in something that is not even in operation yet!
Just out of interest, has anyone seen the f/o pay scales?
