Airbase One
Find alternate airports fast with this nifty tool. Save megabucks by flying into the cheaper destinations, then drive the remaining miles.

Alternate Airports
From 1Travel.com. An alternate city database. Click on the city and you will be shown alternate cities, the miles you will have to drive... and the type of road (divided, freeway, etc.) with the speed limit! Handy, huh? 1Travel.com also gives an excellent illustration of the savings you can achieve by hopping planes on cheaper routes. (don't try and use the search function, it frustrated the peepers out of me, just find your city and click on it)

Drive & Fly Guide
Drive a little, fly for less on low cost carriers. A quick convenient way to locate only those alternate airports that are served by a low-fare airline. You have a choice of performing a search using your departure city or your destination city. As the majors often compete with the low fare airlines on those routes, consumers WIN by saving MORE.
