It is always difficult when joining a brand new airline. All I can say is that the manager is someone that you can trust on and that keeps his commitment. His team has to be reliable and of course he asked his former "favorite" colleagues to join his team. It is far from easy to launch an airline and I wish them a successful story.
If you want to join, you will certainly be facing tough roster at the beginning but I am sure, when everything will be set up, conditions will improve continuously. A small airline like this should take care of their employee to be successful and I think they knows what to do.
