You must store them in their own case, and wrap them with LDPE to prevent anyone from opening the case. Surely at the airport you can ask for indications.
I would transport by train or truck. Depending on delivery times.
since the transportation is taxis, cars, bus, or donkey I would transport the guitars by bus this would be the best way and and the fasted way to get the guitars to the United States this is and would be the fastest way as well as the safety to me.
I would not use the pipeline. It is easier and cost less to do intermodal shipping.
That is so funny I am writing a paper on the same subject, well to give a little bit of help to my fellow students I would have to say I would transport the guitars from Mexico to the US by air because from what I found in my research is that the air traffic control from there to here is very tight they keep a close eye on what goes in and out so your guitars would make it safe id you chose to transport this way. Good luck...
In a box
I have tried it and dosent make much of a diffrence!
Caster wheels are wheels that swivel, allowing the object to move in any direction. Shopping carts use caster wheels, and caster wheels are commonly attached to furniture to make it mobile.
Nothing. "Shadow Caster" is English why would you think it would have meaning in Spanish since it is English? that is a stupid thing to think.
You could travel by boat, but it would be a pretty large voyage.
IATA (International Air Transport Association) code would be MEX.If you refer as local abbreviations, there is no official one, but most Mexicans know Mexico City as Mexico, "Ciudad de Mexico" or "La Capital".
