of course if you want the BT make sure to add another 5.5-6 K eur for 6 t&g!
Yes AIr Baltic, they do some offer like you wrote down , specially in summer time, but it's on the Classic Type, and yes for 1k you get the differences courses for the Ng version (1 hour Sim and a multiple choice)...but...not an exaustive training althought people there are nice and helpfull!
