On December 29th I called the Select Executive Amtrak Rep to book at trip from Los Angeles Union station(LAX) to Tucson for February 12th, using cash. I check on line before I called and found the Sunset Limited roomette cost $238...while strangely the Texas Eagle #422, same departure, same train, same tracks, cost $348. So I told the rep that I wanted to book LAX to Tucson for February 12th and was told that it would cost $348. I said I want the $238 train, Train #2. Ahhh, I was told that costs $238. I asked why would anyone pay $110 more to ride the same tracks? I was told, " Well people prefer that." I also wondered why the rep would have choosen a more expensive train for me. I asked no more questions and booked my ticket on the Sunset Limited. Later that same day December 29th, I decided to have my wife call to book the same exact booking I had just made. She was also first booked on Train 422 and told it would be $348. When she challenged the cost and asked why she was not told of the Sunset Limited, she was given the same answer I was given earlier that same day. So...What is going on? Has anyone else gotten this "up charge"? If I hadn't been looking at the Amtrak website, I would have assumed the only train from LAX- Tucson cost $348. Something is going on that shouldn't. Help me understand.
