Meet vs. Zoom at 30k Feet

Members of my teams happened to be presenting at two entirely different events today, on back-to-back hours. One one Zoom, one on Meet. Both streamed from American Airlines' Go Go Inflight on an A319. The Meet worked. A few moments of dead air, but mostly streamed live audio and slides, complete with transcription. Zoom failed to connect over app and multiple browsers. At this point I've been trying Zoom for 15 minutes and will probably give up.
