The Frommers' August e-newsletter discussed Spirit Airline's giving away of all seats on September 11.

Now, National Airlines is following suit; the seats aren't free, but they're only a single buck, and all the money collected will be donated to a suitable charity. Vegas-based National is also offering first-class seats for their usual low upgrade fees–plus the extra dollar–meaning you can fly first-class from New York City to Vegas for only $201. You can take advantage of this deal if you can depart out of NYC, Newark, Philadelphia, Washington, D.C., Miami, West Palm Beach, Chicago, Dallas/Fort Worth, Seattle, San Francisco, Los Angeles, Reno or Las Vegas. When Spirit made their announcement, all 13,000 seats were taken in under 24 hours. For more on-line info, see www.nationalairlines.com/itn/index.asp?page=webspecials.asp.

You can book online at www.nationalairlines.com,or at any of the big three booking sites; www.travelocity.com, www.orbitz.com, or www.expedia.com.
