Of course. It does all the time. It can travel through anything with molecules. Probably not a vaccum though.

Air travel is the very fast and convenient. There are many different airline companies offering both international and domestic flights.

The simpler approach would be to outsource travel services. These companies will identify some of the best air travel deals to your destination.
