Finally! It was completely ridiculous that this wasn't done from the start. For those who don't know, the Metro line used to be as close as less than a mile from the airport for decades. The story I read on the news was that someone was worried about the loss of parking revenue for the airport (/city?). Realize that this is also one of the most car-congested airports around, which totally fits with it belonging to one of the most car-congested cities.
