I'm an Alaska (relatively) frequent flyer. That airline offers a free "messaging" plan, that lets you send and receive messages on apps like iMessage, Facebook Messenger and Whatsapp. Though, it somehow prevents images/attachments from coming through on those platforms. I've always wondered how this is implemented technically, and if it might be possible to setup some kind of protocol/wrapper to send data that looks…

I've also wondered why Grindr but not Tinder works on the "messaging only" plan. Someone at Alaska must have had fun with that one. Flightaware.com also works, presumably because Alaska uses Flightaware for its tracking map.
Unfortunately, I couldn't get it to load on my Alaskan flight a few days ago on the free messaging plan. Maybe they've changed it

I used to do the same thing at hotels. Still often works. nmap -sn 192.168.0.1-255 To find everyone on the network, then start spoofing each of their MACs until you find one that works
Does that work if both of you are trying to send/receive packets at the same time?
When my son was younger - maybe 9 or 10 or so, we were on a plane and he was using his phone and I looked over his shoulder and realized he was on the internet... but I hadn't paid for an internet plan. I said, "son, how are you using the internet?" He said, "oh, a kid at school showed me - if you go here" (he opened up the wifi settings where the DHCP assigned IP address is) "and start changing the numbers, eventual…

I should probably know the answer, but what happens when two devices have the same MAC address?
MAC is Layer 2, IP address is Layer 3. One way or another, the packet destined for the person you're spoofing will end up at your computer and work its way through the layers. From there, if it's a TCP/IP packet, I think it'll get filtered out at Layer 4 (transport) because your computer wasn't one of the parties that initiated the TCP connection (the sequence numbers won't line up, etc).
Packets being broadcast to multiple machines is common enough in various network setups, it's up to the individual machine to decide whether to process or drop the packet.

This seems like a poor slippery slope argument. It’s not as if charging for internet is new, it’s been what? 20 years? And yet they still don’t charge for water
Is that an American thing? Absolutely paying for the water here.

Elevation is relative to sea level, not the ground.
The plane is measuring altitude , which is relative to a reference point, unlike elevation which is relative to sea level. And if the altitude is determined by pressure sensor, musn't it be relative to the ground directly below the plane, anyway? (Although personally, I agree with the sibling comment that the variability is likely an artifact of the sensor resolution.)
