Vueling pays as low as wizzair does.
I have no sympathy to the Vueling boys, hiring 200 hours stupid cadets with their trouser down, accepting ANYTHING to be able to sit in an A320. A 6 month contract and 830 euros gross per month plus a type rating to pay. Then you have lots of heavy landings, tailstrikes, crap english language on ATC. This airline is just a flying school. Plus they do have lots of maintenance issues. Lots, lots of issues. The spanish CAA is very concerned about that.
