I think that this is probaby true, to an extent, with slight corrections. The retirement flights will be not to LAS, but to Mojave, CA. As with other retirement flights to Mojave, the crew will then deadhead to Las Vegas for a layover before returning to Atlanta. The retirement flights will be open to employees; however, only a limited number of people will be accommodated. Although I don't know of any official "parties" in Vegas after the flights, I would fully expect the crew and passengers to have a good time at the hotel during their layover.
