Starting Oct. 24, the Dallas-based carrier will offer free in-flight WiFi across its fleet, doing away with its $8-per-flight fee for internet access.

There’s one small catch — you need to be a Rapid Rewards loyalty member to get free in-flight WiFi.

The move is part of a first-ever collaboration between Southwest and T-Mobile, though you don’t need to be a T-Mobile customer to get the free WiFi.

We are focused on making sure our Customers have a great experience from the time they book a flight to the time they reach their destination,” Tony Roach, Executive Vice President, Chief Customer & Brand Officer at Southwest Airlines, said in a statement.

This is part of our ongoing commitment to elevate the cabin experience, with free WiFi being just one of the many enhancements Customers will see in the months ahead.”

The deal makes Southwest the largest domestic carrier in the country to offer free internet access across all internet-enabled aircraft — making it available on more than 800 aircraft by the end of the year.
