but they charge $200 for a bike to travel, plus then I would have to ship my travel case home or to the finish.
At the risk of sounding like a shill, I enjoyed my experience with bikeflights.com. They ship your bike via FedEx and have a deal with them. Back in June I used them to ship my large LHT, racks, stove and fule bottle in a CrateWorks plastic case from Philadelpia to Missoula. I didn't have access to a scale so I wildly overestimated the package at 90 lbs. Four day shipping was $73 each way, which included a $5 charge for picking the bike up at a local shop. If you can transport the box to a FedEx/Kinkos location you can avoid that charge. Before I purchased the service I played around on their web site. Had the weight been 70 lbs. the base charge would have been $63. My airline wanted $175 each way. I used the savings to have the bike professionally packed and then reassembled and tuned in Missoula.
As noted, you don't have to use a personal travel case. Have the bike professionally packed in a regular bike box, or do it yourself. Remember that your bike likely travelled half way around the world via boat, train and/or truck to get to the shop in such a box.
