Airline troubles!!

Alec Baldwin is the second celebrity that I have read about getting kicked off a flight for childish things. Today Alec got kicked off a LAX flight for not turning off his phone when the flight attendant told him to. I may not understand the acquirement for the airlines but im pretty sure all phones now have something to not interfere with the signals. A couple minuets later Alec tweeted "Flight attendant on American reamed me out 4 playing WORDS W FRIENDS while we sat at the gate, not moving. #nowonderamericaairisbankrupt." I don't know what it is with airlines these days but some of the stuff i read is ridiculous.
