I've got a friend who worked there as an F/O for about a year. Ran away as fast as he could when he got a new job.
Perks: Relatively easy to get a job there. You're flying heavies earlier than you normally would. You get to see the world. Four day sits in honolulu. You can live where you want.
Drawbacks: 18 day trips. No lines, all reserve. Kuwaitt is a dry country. Lowest pay in supplemental industry. LOTS of deadhead. On other airlines. In coach. Upgrade isn't seniority based. Non Union.
