I first noticed this on a flight to Paris. I was building a Flutter app using Firestore, and tho I had not paid for the onboard wifi (I was doing local development) I was connected and all of my Firestore calls were succeeding.I thought this was novel, and assumed it was just something to do with websockets, so I switched to another, non-firebase-but-yes-websockets project and noticed it didn't work.
At the time, I debated moving calls to Firebase just so that I could work for free while I was on flights, but realized the ROI wasn't remotely there. Glad to finally have someone else acknowledge it happening, and give some insight as to why.
Some flights have a free tier of wifi that allows messaging apps. Google Voice and Google Hangouts usually work on those so wouldn't be surprised if some other Google services make it through.
