At the time, airlines were allowing two free checked bags per passenger. Two project volunteers were able to transport 50 XO laptops, each taking two crates as checked luggage and extra XO laptops in their carry-on bag. As a result, we ended up having virtually no excess baggage fees, and our overall shipping costs were minimal. This saved us hundreds of dollars.
When the laptops reached their destination, we removed one side of each crate and turned the crates into charging shelves. The extra side panels were used to hold the stacked crates together. Power strips were inserted into a compartment on the side of the crates. The XO adapter/power cords were plugged into these, then run along the top of each crate, with a short length of the end hanging loose, just enough to plug into the shelved XOs.
We also brought extra batteries (seen on the shelves). We swap these out with charged laptop batteries and then charge the extras while in the XO laptops.
