Thank you very much for your answer!
Concerning Thai smile, I was considering to fly regularly with them, because of their close relationship with Thai airways. But, I still have some difficulties to find precise informations on their own safety standarts.
E.g. I know that Thai smile pilots might have different contracts than Thai airways pilots. Hence, I was wondering how this very young airline has arrived to attract sufficiently experienced pilots in a so short time? (I mean if no experienced Thai airways pilots work for them?)
Also, I usually like to try to fly with companies having some kind of international safety audits. This helps some non-professional guy like me to trust in an airline. In the case of Thai smile, I do not know whether they have their own international safety audit? (I mean independently of Thai airways?)
Once again thank you very much for your fast answer and help that I really appreciate!
