I found the same thing by checking fares for future travel. When I compared fares for roomette with 1 vs 2 passengers, the cost for the additional passenger was about $100 more than the coach fare. I've also noticed that sleeper accommodation fares have increased substantially, especially for bedrooms. They are now typically twice the cost of a roomette. I've been taking the Southwest Chief from Cin-FLG in a roomette for the past four years in March and point cost has gone up 70%, and bedroom cash price has tripled..
