I made a discovery which may be helpful to those flying to DC on American Airlines. They have a program on their website-“Travel Perks”. For $139 you enroll in a program which gives you $100 off two tickets twice a year. So, if you and a friend or spouse is going to DC, you can knock $200 plus tax right off the top of the cost of the tickets. There are lots of other perks too, but Im not working for American, I just think this works out great for those of us that can use this airline.
