How to Find Cheap Airfares within the United States

Most of us do not enjoy shopping for airfares. Very few of us would want to spend many hours each day online searching for a slightly lower price on a ticket.

Notice the word "perhaps." Airlines sometimes decline requests for these refunds. But it never hurts to ask, right?
