It doesn't have the same food selections, but employees who work at one of the classified defense installations, including Area 51, in the Southwest desert commute daily by 737.

The Air Force has a classified airline known as JANET. They fly 6 unmarked 737-600's and various executive aircraft out McCarran International in Las Vegas. Those defense installations are so far out in the boondocks, the employees live in Vegas and commute daily by airliner. The terminal is unmarked on the West (Strip) side of the airport. I doubt many tourists know what goes on there, but many locals do.

The 737's are somewhat conspicuous since they have no markings, but at least the 600's look much less out of place than the old 200's they flew for years.
