right now, there's just one sleeper that goes the entire Lax to NOL and the crew occupies 6 of those rooms, leaving just a handful of rooms for sale to general public. There is a 2nd sleeper that goes part of the way (Lax to San Antonio), but if you are boarding east of San Antonio or getting off at any stops east of San Antonio, it's very hard to get a room all the way through. You might try booking Lax to El Paso and then El Paso to Nol. Even though you might have to change rooms, the crew might keep you in the same room all the way thru. We used to have 2 sleepers all the way thru, but Amtrak took off one during Covid and Amtrak is very beaurocratic and takes forever to change. I make about 10 round trips a year in the sleeper between Houston and LAX and I've been fighting this problem for a long long time. My educated guess is they will put back that 2nd sleeper, sometime between now and the next 5 years
