Best Internet for Working on a Plane?

For people who travel a lot for work, what’s the best way to get WiFi so you can work on the plane? I used to be able to buy the United WiFi and it was a secured network so would work on my laptop (sometimes slow/unreliable). Now that they’ve added Starlink (which is personally life changing and so amazing), my laptop won’t connect because it’s a public network.

Any hacks or ideas? Can I buy some sort of hotspot? Turn off my vpn?
