Lots of interesting information. I didn't know it was different WIFI systems on the airbuses versus boeings -- which does explain why I never ever seem to connect on the 737 Max 8 or Dreamliners compared to Airbuses. I've tried with Safari and Edge, but didn't with Chrome so I'll give that a shot when I'm having issues.

My flight yesterday was on an A321, connected immediately with no issues or drops -- I htink this is the first time in months!
