I don't think the average airport taveler and the average american line up that well. Someone making 7$ an hour is going to fly far less than someone making 70$ an hour.
Yea, but I don't think doubling would be enough. Also the economic value of someone’s time is more than what they are paid. I get billed out 40 hours a week @ over 100$ an hour, but that does not end up in my paycheck.
Granted reducing wait times is not going to get directly translated into extra working hours, but the current system also cost travelers more than just their time spent in line.
