Once again, an airline (this time Virgin) left their passengers stuck on a tarmac for 7 hours in NY due to bad weather preventing their takeoff. Which prompted Congress to talk about creating a "Passenger's Bill of Rights" that would put a limit on the amount of time airlines could keep passengers immobile on the tarmac. It bothers me that Congress would have to do this, and makes me very suspicious of monopoly-like tactics being employed by the airlines. Otherwise, why wouldn't one single airline advertise an X-hour maximum tarmac time before they unload?
