A close friend of mine works there, but on the A310.
Its a Portuguese company, no stakes owned by airbus or any other connection except they use their birds.
Belongs to former Airluxor management (also Pt).
The 330 I heard they have some kind of leasing based in London.
Work scheme I believe irs also the same: 20 on 10 off
From my understanding, its not a dream job, but not a bad one either. There's better and worse out there.
Also, I believe you need some kind of connections to get there. Or at least a very nice recomendation.
Good luck on it
Cheers.
