Maybe you should pay a fee to use the elevator, the toilet, the electricity for the Coffee machine and the heating and cooling. Why should your employer pay for that? You are a real jerk. The fact is you can walk, LGA may be an exception but you cant walk to most airports, most airports wont allow you to walk, and as someone already pointed out mass transit isn't really an option, AA isn't being asked to bear the cost of us getting to work, but once we are there they pay the cost of having a place to put our means of getting there, not always a very convenient place either, we are probably further from our car than you live from your office. Many of us have to take a bus once we get to work, on our own time, to actually get to the location where they have us working, so after driving to the airport we lose as much as an hour each day of unpaid time.
