(WJW) — Subway is giving away 10,000 footlong subs Thursday for National Sandwich Day, but to get one, you’ll have to go 35,000 feet in the air.

The sandwich chain’s new sweepstakes is open to air travelers stuck in the middle seat on a Nov. 3 flight.

They will need to upload a photo of themselves flying in the middle seat to SubwaySandwichSeat.com. They will be entered to win a gift card for one Subway Series footlong sandwich. The promotion ends just before midnight Thursday.

“With air travel demand hitting record highs ahead of holiday travel season, Subway is making flying a bit better for those passengers in the dreaded ‘sandwich seat,'” reads a news release on the promotion.

Even if you didn’t fly Thursday, Subway sandwiches are “buy one, get one” right now using promo code FLBOGO on Subway.com or on the Subway app.

But Subway isn’t the only one handing out deals on National Sandwich Day. Here is a list of others:
