BS. BS. BS. Phone calls are allowed on planes ! Last flight I took, the back of the seat in front of me had a freaking phone and a credit card swipe and it was encouraged to be used. Evey row had them.
So its OK for me to phone and carry on a conversation on the phone but not over a WiFi ? That's BS !
Its all about them not being able to charge you for it. God forbid you get a free long distance phone call out of them.
And sorry everyone but an airplane is not your private space. You are not entitled to privacy on a plane unless you paid for a private room. People have the right to carry on conversations whether its online or with the person sitting next to them.
