The thing to remember for shipping by air is that price is based on volume, not just weight - so being able to get the bike into smallest box possible without compromising protection is the trick. I generally use DHL - if you use one of the online bookers, you'll save on the standard price - I sent a bike to Taiwan and it was delivered 2 days later - online tracking too. I wouldn't use Parcelforce - stuff disappears into the ether never to be seen again.
