Last-minute tips to save on Fourth of July travel, from gas to airport parking

Americans are expected to hit the road and take to the skies in record numbers for the upcoming Fourth of July holiday.

For those seeking last-minute deals or hoping to keep to a strict budget, ABC News chief transportation correspondent Gio Benitez shared a few tips that could come in handy for anyone looking to save or stretch their dollar.

Those taking to the skies during the holiday stretch could still find savings on airfare, even if their flight has already been booked.

Travelers can check to see if the original price of the flight has gone down, for example, and if it has, they can call the airline, let them know the price dropped and ask for a credit for the fare difference.

While this may work on most major airlines, it does not apply to tickets purchased within the basic economy fare class.
