The cheapest way to travel across America depends on the mode of transportation. Generally speaking, taking the bus or the train is the most cost effective way to cover a long distance. If you plan ahead, long-distance bus companies such as Greyhound and Megabus often offer discounted fares.
Riding the bus is often much cheaper than taking a flight, and allows people to evade airport hassles. But trips can take far longer than advertised and disruptions can hit buses as surely as they hit planes.
Water transportation is the least expensive and slowest mode of freight transport. It is generally used to transport heavy products over long distances when speed is not an issue.
A family of five may find a road trip more economical than buying plane tickets, she said. However, if only one or two people are going on the trip, driving may not be the more affordable option once gas and food are factored in.

Plane travel is safest, reports Ian Savage, of the Dept. of Economics & Transportation Center at Norwestern University, in the Huff Post Live video clip above. Trains are three times more dangerous than flying but safer than traveling by car (which is 40 times more risky than flying), according to Savage.
No.The speed difference between the fastest aircraft and the fastest trains is about an order of magnitude. The atmospheric density at ground level would generate too much drag for a train to go as fast as a typical jetliner, let alone go supersonic.
