In this case, the problem isn't BT, it's the advertising sites that publish misleading ads on many companies. There is only one base: Riga. You start your duty in Riga and you end it there. There are operational bases from which aircraft fly, but as a crew you fly from there and sleep in a hotel afterwards for 5 days.
I've been flying for them for several years and I'm fed up. The rosters in winter are very chill, but from March to October it's 3/4 ACMI layovers in Zurich or Munich per month. The work-life balance is non-existent with 20 days a month away from home. The rosters are FLEX and sometimes make no sense at all. In August I have a 5-1-5-2-6-1-6-4. It's not sustainable in the long term.
The management has brushed off criticism of the conditions with a ‘take it or leave it’ policy. The result: no improvement and many pilots have resigned or are in the process of leaving. Some are happy.
As far as salary is concerned, I got an average of €3,200 net after tax as an FO1, plus €500 per diem. There's been a small increase of €300 gross recently.
Beyond that, airBaltic is not a bad company. If we had the possibility of being based in Tallinn and Vilnius, with a fix roster, that would be a very good condition. In the meantime, it's not worth it unless you're on a turboprop or want to switch to a left seat.
The aircraft are well maintained, and most of my colleagues are very professional.
