I flew back from Santiago Airport in Spain. The airport will sell you a box for your bike: cost 14.50 euro.
The guy who boxed my friend's bike was very helpful, and your luggage can be shrink wrapped for 8 euro. I also had my my FOLDING bike, an Airnmal, shrink-wrapped in its bag and took it on the plane as hand luggage, the wheels in their bag and my panniers went the usual way. |
