That was grandfathered in after 9/11 to allow them to have that service.... Which is great... But why only allow them? I think the knee jerk reaction was great at the time. But now it is time to allow airlines to make use of such... Also lets stop Nancy and others from taking their private jets and be like many others of our politicians and just get on a commercial aircraft and go to and from work.... I take pleanty of senators and congressmen in and out all week long.... She wouldnt have an excuse if we could go DCA-SFO !
