That’s exactly what T-Mobile says here:

Here’s the relevant part if you don’t want to click the link:

• T-Mobile Inflight is offered on Gogo-enabled flights by several domestic carriers, such as:
  • Alaska Airlines
  • American Airlines (on limited flights)
  • Delta Airlines (on most flights)
• To check if your upcoming flight is Gogo-enabled, contact your airline.
