I will gladly take Amtrak over any airline to travel with a bike.

What I really like about Amtrak is that a week before you travel, your ticket will still be affordable. So, if doing a longer bike tour, you don't have to get your ticket months in advance like you would on an airline.

My biggest complaint is that there are not enough Amtrak routes, my options are quite limited on Amtrak in the middle of the country.
