I've noticed that airline wifi doesn't block DNS traffic. You can likely accomplish the same thing with a DNS tunnel like Iodine (https://github.com/yarrick/iodine).
Many years ago, I noticed I could browse the Google Play Store on a flight WiFi without paying for it. No images would load and no apps would download, but I could browse through app listings and read reviews.
Probably not. I bet something in Android didn't work properly until they whitelisted some Google domains — for example, maybe it didn't detect the Internet connection when the user paid for it, or maybe something on the entertainment tablets broke (I don't know if they usually run Android or something else).

Would this be related to DNS?
