In case you are not aware of the reality, first year salary (First Officer) at Iberia: 2400€ per month all included. (IBeria mainline not Iberia Express).
Easyjet crap deal as well, small base likely to close down any time, small network, crap staff benefits, bad roster, bad contract.
You won't find many Vueling pilots leaving to go to Iberia or easyJet, that's for sure.
What is true thow is that Vueling have recruited people with High experience (ex Emirates, Qatar, etc....).
Reason of the recruitment: fleet growth and new FTL rules...
This year 28% of applicants who were present on the first step of the selection process were offered at job...
