“I flew on a Boeing 737 Max 9 in 2019. I remember it had a very weird climb to cruising altitude compared to other airplanes I had flown on. It was also a wireless WiFi streaming entertainment airplane that needed passengers to use their phones to stream to the airline app that had to be installed prior to take off. It had weird cabin lighting I had not seen before.” PhonesLightingAirlineClimbAirplanesWifiMax 9Boeing 737CabinCruising Altitude Author:Steven Magee
