Yes with Iberia, Air Madrid, Air Europa and above all Air Nostrum.
Nothing sure, you can encounter very nice captains (

) as well as bloody B

ones...
Note that those companies are just some spanish ones ( with UK companies, just forget it, don't even waste your time trying ).
Things are not getting as easy and automatic as it used to be 5 years ago. You must speak spanish as well

..
Good luck and welcome to Europe
