Travelers south of the border are getting some decent deals on airplane tickets.
The U.S. Department of Transportation reports the average price of domestic airfare dropped to $363 in the fourth quarter of 2015 -- the lowest level since 2010.
The 8.3% annual drop is due largely in part to cheap oil. The price of oil fell to as low as $33.98 U.S. a barrel in the last three months of 2015.
But while low oil prices are a win for passengers, it can take some time to trickle down to their wallets.
Cheap oil boosts airlines' profits and allows them to grow and add routes and buy better planes.
Low-cost carriers, like Spirit Airlines and Allegiant Air, have been expanding to new cities and putting pressure on the existing carriers to drop their prices in order to compete.
Travelers in Chicago, Dallas and Philadelphia are catching some of the biggest prices discounts in the country as the competition heats up in the cities, he added.
The department's figures don't include added fees for things like checked luggage or more legroom, which are also big revenue boosters and don't go away when oil prices drop.
