Wouldn't know about UAL/DAL/AA/ etal., as I've been an expat for many years, and have had the benefit of being an educated consumer, and contract negotiator before accepting any position.

Be very careful should this be your first experience beyond the Boarders of the US. Make sure you do your home work. For example, many places do not provide transport to and from the location of the operation. Many do not provide accommodations while awaiting approvals from DGCAs. Many are very dodgy and evasive on terms and conditions. Some offer contracts written in there home language too, without interpretation. Some realize that you may have spent a great deal of money and will sign any documents, and accept the terms and conditions regardless of what was promised in there Red Herring. As the saying goes... "Buyer beware."

But good luck to you just the same aviatorhi.
