Traveling Overseas with Bikes
So, I'm a US Expatriate. That is, a US citizen, living in Dubai. We travel. And we travel with our bikes. 

There is no need for stress regarding traveling with a bike. It just requires preparation. When you buy your tickets, tell them you will be checking a bike case. It legitimately falls under the sporting goods exemptions for oversized luggage. Most airlines have a flat fee. American, who we're flying with in 2 days, charges 150 USD each way. 

Print the airline policies regarding bikes to take with you to checkin. Many airlines employees don't know their own policies, so you need proof for their sake. 

Use a hard case. Some airlines require it no matter what, and others won't guarantee the condition of your bike without one. 

S&amp;S couplers are a good idea, and the electrical issues can be worked out.  A 62cm frame will fit most boxes, especially if you have couplers. And if you're unsure, look at B&amp;W Bike cases. Good quality, plenty big, and airline safe. As for losing or breaking your bikes, nothing to be done there. Except check the bikes thoroughly before you leave the airport, and make them pay. They must replace or repair a damaged or missing bike. While it will be unpleasant, it won't be the end of the world. 

Mostly, it's not too big a deal. Delta's policies state that their 200 USD fees are not supposed to be for each leg. It's supposed to be for The whole distance, city to city, unless you booked each leg separately. 

That's the average, about 200 each way. Be prepared, and don't back down. You'll be fine.
