Adding a passenger to sleeper reservation?
In a few weeks I'm taking a trip on the Southwest Chief. I'm looking at a bedroom to reserve right now, and since it's available, I'd like to just go ahead and reserve it.
However, a friend might be coming with me, and doesn't know with certainty yet.
If he's able to make it, and I know ahead of departure, can I have a 2nd passenger added to the reservation and pay the fare difference? Nothing else about the reservtion would be changing (origin, destination, date, or room type).
Thanks much.
