They're so concerned about people making calls, yet they've had airline phones for years.
And how is it any worse to be trapped on a plane with such idiots than on a bus? At least on a plane you're only stuck with them for a couple hours, not all day on an overland trip.
Airline phones = Way Expensive = Nobody used them = No Problem
Idiots on a bus = People who don't have enough money to fly = Fewer people used them = Not as big a problem.
