I've only travelled with my bike once so I don't have a whole lot of experiences to draw from. I took it with me on a trip to France and it seemed like the best way to go at that time was to fly it with me. No problems with damages from anyone in our group so flying worked well for us.

The downside to flying is it's a pain to lug the big case through the airport. Luckily, most cases have wheels which makes it a little easier. Also, some airlines charge a fee to transport bikes. I've heard as much as $75 each way. We were travelling on a group rate that included the bike so I don't know how much we paid. If you decide to fly with it, find out the policy of the airline beforehand so you don't get surprised at the check-in counter.

I'm taking a trip in a couple of weeks and plan to bring my bike. This time, we're going to ship the bikes. We decided it would be cheaper/easier. The downside of this is being without your bike since you have to ship it enough ahead of time to make sure it gets there. And, it won't get back to you until several days after you get home.

I'll let you know how the shipping option worked out once I get back.
