I can see this leading to AeroMobile cleaning up. They have microcells on many international flights that charge you crazy roaming rates particularly for data. Your phone connects and uses it automatically. Right now mostly only intentionally as people are fairly used to actually turning airplane mode on.

My carrier Telstra charges $3/MB still now for AeroMobile. Madness. I wonder if anyone has a non stupid rate with them? It’s also 75c/SMS and $5/minute for calls.
