What is the best domestic airline in the US?

• We will be traveling from Manila via Delta Airlines or Philippine Airlines (PAL) to Los Angeles. We are planning to travel to different states in the U.S. from L.A. to New York City or Washington, D.C. to San Francisco. Any recommendations to cheaper airlines that travel within mainland US?

• Answer:

  The cheapest domestic airline is often Southwest. At one time you could purchase a book or tickets for domestic travel in a foreign country. Check the web sites to see about your flights and costs. Look at www.bestfares.com and each major airlines. Virgin does not travel to all of your destinations.
