Travelers can see more of America for less with one-way car rental promotions from Avis, Budget and Hertz. These companies need to get cars out of the Sunshine State — where they've been used all winter in the busy tourist season. If you're willing to pick up a car at a Florida airport and leave it at selected locations across the country, you'll save major bucks. These one-way rentals are available with unlimited mileage and no drop-off fees.

The trick is to find a cheap one-way airfare to Florida. Check out fares — with a budget airline such as Southwest or Jet Blue — to Fort Lauderdale, Jacksonville, Miami, Orlando, Pensacola, Sarasota, Tampa and West Palm Beach.

Avis and Budget are offering minivans for $14.99 per day or $104.65 per week. Budget also offers other car classes starting at for $19.95 per day or $139.65 per week. Cars may be rented for a maximum of seven days, and travel is valid through June 30. Avis and Budget permit drop-offs in most locations in the continental United States, except California.

While Hertz has the lowest rates, starting at $9.99 per day or $89.99 per week, their cars can't be dropped off in Texas. Cars may be rented for 14 days, and travel is valid through May 15. Hertz rentals may be dropped off at selected East Coast and Midwest locations.
