The chain is offering free subs through Sept. 7

The only thing better than a footlong sandwich? Two footlong sandwiches!

Subway is offering a buy-one-get-one-free deal on subs through Sept. 7 at participating restaurants.

To score two sandwiches for the price of one, fans must use the promo code “FLBOGO” when ordering on the app or online. Customers can only snag one free sandwich per order, but the promo will reset every day during the giveaway period.

The sandwich spot has exciting news this week on land — and in the air. On Tuesday, the chain revealed “Subway in the Sky”: a new dining experience on a sandwich-shaped blimp.

The sub-inspired aircraft is a supersized version of the chain’s footlong sandwiches. The 180-foot-long blimp has a restaurant underneath it with room for six guests to enjoy sandwiches.

Guests will enjoy the four Deli Heroes sandwiches, a sandwich line introduced in July and meant to show-off the chain’s new freshly-sliced meat, aboard the airborne restaurant.

The "flying footlong," as they're calling it, will take to the sky on Sept. 1 and stop in several cities across the country, picking up sandwich-lovers along the way. The aircraft will take off in Kansas City (Sept. 5-7), Atlanta (Sept 13-14), Orlando (Sept. 19-20) and Miami (Sept. 24 and 26). Up to 40 fans per day can take a ride 1,000 feet in the sky.

Fans can reserve their spots on the blimp at Register.SubwayInTheSky.com starting on Sept. 2.

Dairy Queen also has a sweet deal for back to school. Customers can score Blizzards for 85 cents from Sept. 11 through Sept. 24. The only catch: Fans must use the DQ app to grab the deal.
