Air Travel within the USA

Once in the U.S., international travelers can fly between states on U.S. domestic airlines. Airplanes offer a convenient means to get from one city to another. Most major cities have at least one airport with direct and connecting flights available. Traveling from the East Coast to the West Coast takes less than six hours by air, compared with several days of driving or train travel.

If you plan ahead, you can save a significant amount of money on airfare. Waiting until the last minute can be expensive. Summer is peak travel season in the USA making flights more expensive during this time frame. Traveling on or around public holidays and during spring break (usually in March) can also be more costly.

Most major airlines use electronic-ticket systems for ticketing passengers. Tickets usually carry a confirmation number, which includes information for the entire booking. You can check in online and print the boarding pass, or you can check in at the airport at a kiosk or the ticket counter. Allow extra time because there’s usually a line. Check with the airline in advance for delays, cancellations or flight changes.
