Doubling bandwidth available to an airplane is awesome of course, but it seems like people are expecting a giant step here and not a simple doubling. It will be most noticeable in decreased latency so much better for phone calls and Zoom meetings. But the use case of 1/3 of passengers streaming video to their personal terminal seems already solved with existing satellite providers.

"Starlink delivers up to 40-220 Mbps download speed to each plane, enabling all passengers to access streaming-capable internet at the same time. With latency less than 99 ms, passengers can engage in activities previously not functional in flight, including video calls, online gaming, virtual private networks and other high data rate activities."

"SpaceX has revealed the official details of its Starlink satellite internet service for aviation, and it promises to deliver speeds of up to 350 Mbps for each airplane.... If Starlink Aviation can truly deliver on SpaceX's promises, that would make it a lot faster than other satellite options that only offer speeds of up to 100 Mbps per plane at most."
