Last time I used Greyhound with a box bike was between Denver and Frisco CO. It was not a good experience but got me there.
A ticket gives you one free check bag. I had the bike and a second bag. The second bag was going to cost me more then the online ticket fare. So I booked two tickets in my name. You can only imagine the confusion that caused. The manager had to tell the counter person that I have two tickets so I get two seats and two free checked bags.
check baggage is not really check baggage. They put a tag on it and have you carry it to the bus so the driver can load it.
Upon reaching Frisco the driver all most drove off with out unloading the bike and bag. Had to tell him twice that I had check below.
Add to that a two hour delay because they didn’t have a rested drive available.
Bike arrived un damaged but a experience. Would have to think hard before I did it again
