American sandwich chain Subway has partnered with four major online delivery platforms to offer food from across 9000 restaurants in the US.

As part of the deal, DoorDash, Grubhub, Postmates and Uber Eats will deliver sandwiches, wraps and salads to customers from Subway restaurants.

Subway global convenience senior director Michael Lang said: “Delivery is more than just giving our guests a way to order the sandwiches they want.

“Amazing partners like DoorDash, Grubhub, Postmates, and Uber Eats give us the opportunity to reach guests wherever they are.”

“We want to connect with consumers and give them the convenience of choice, whether it’s in a customised, made-to-order sandwich or in how they get their meals.

“Amazing partners like DoorDash, Grubhub, Postmates, and Uber Eats give us the opportunity to reach guests wherever they are and whenever they get a Subway craving.”
