Dunno what a CASS is, but Kalitta will get you as far as Bahrain, via JFK and BRU. They offer seats to almost everyone with an airline ID badge. Commercial tickets available between BAH and KWI on GF, a quick check on their website revealed a ticket price of around USD 270 return; I'm fairly certain that if you shop around there are cheaper options available.
FedEx is a regualar in DXB, and commercial tickets are also available from there to KWI. Who knows, Feddie might even serve Kuwait from Dubsie. You may also want to check out SHJ with either Atlas or Polar. It's a short 45 min drive down from SHJ to DXB. Air Arabia out of AUH (a further 1 hour drive down from DXB) is the local LCC in the area, you may want to check if they have a sweet deal on KWI.
I can't remember ever having seen the Brown Brigade in that part of the world, but maybe I just wasn't paying attention.
Best of luck.
