A word of caution,
At the moment there are many foreign F/O's 'working' for Pegasus. They completed their TR last year/recently.Pegasus told them that to complete 200 hours linetraining would take aproximately 3 months after the TR.
In fact, it will take them much longer, hence they can expect their first salaries at least 4 months later than expected.
So, if you are planning to do the typerating at Pegasus and fly hours subsequently, please take into a account a much longer timespan than will be 'promised' to you.
@Özcan,
It seems they prefer Turkish nationals for the long term. The yabancis are just sort of backup.
I believe there are classes starting this year only for Turkish nationals.
