But to be fair easyJet and Ryanair are huge scheduled airlines with a proven track record of hiring zero hours pilots and providing them with top training, and you know unless you royally screw things up you will pretty much have a job at the end at a secure company. Adding to that, one of these 2 on your cv will do you no harm in the long run, and I don't work for these airlines so I have zero bias.
Smartlynx is a acmi with 9 aircraft with no real bases, they work on behalf of other airlines, your entering the unknown so to speak with the program and the training,, you hardly can compare them to RYR and EZY on the stability of the job offer or the track record. Your the first ones, it could go brilliantly or be a damp squib.
