Delta Air Lines is reportedly planning to offer free WiFi to all its passengers as early as next year, according to the Wall Street Journal.

The airline is already testing free wireless internet for members of its frequent flyer programme which is expected to expand significantly through 2023.

According to the report, Delta will start rolling out free WiFi “on a significant portion of its airplanes” before expanding the service to more of its fleet. Once the programme is available for all passengers, it will likely require a SkyMiles loyalty number.

CEO Ed Bastian first announced the airline’s goal of free wireless access in 2018, and it recently stepped up testing. It currently uses Viasat and Intelsat for internet access, and it reportedly plans to equip most of its US domestic fleet with the Viasat service by the end of this year.
