The aircraft are relatively new and in excellent condition. They heavy crew the 737-800s s they fly alot of DOD trips and fly half way round the world with just a fueling stop.
Pay is very low for the work performed, but you will build up alot of flying time and international experience that you can't get flying commuters or regionals.
Catering is very good... so you won't starve.
Your pay comes as scheduled. They have a 401(k) and medical benefits plan which is fairly descent for a charter company. You will never get thrown out of a hotel because the bill was not paid or denied boarding a commercial flight because the ticket was not paid for either. They are very reputable when it comes to fincanial matters.
They are the first 121 carrier to be certified to be a paperless airline too which is a remarkable achievment.
They do have high standards and are very serious as far as training is concerned. If you take the job do the studying as there is no tolerance for substandard performance for obvious reasons.
All in all good company and people to work for.
