I agree.. and frankly, if regulation was re-introduced you could do something about it. Often, persistently late routes are due to competitive scheduling. The airline schedules a flight at a time which is unrealistic to achieve given the volume of traffic available. In a properly regulated market, the slots would be managed by the FAA and such scheduling would not be possible. It is surprising that Southwest are the airline most commonly doing this.. lets see if it is a statistical anomoly or if this is something which is happening consistently. Given the wide geographic spread of the routes, I do think the fault would have to be squarely at the airline's door.
