We've done it. We don't like it, but if we want to fly nonstop to Florida, DCA is the only choice with Jetblue. We live in WV, so Dulles is only 1 hour away. We got a ride to Shady Grove and dragged our bags on the metro. It took 1 hour to get to DCA on metro along with the 1 hour to drive to Shady grove. TSA was very easy, but we didn't like DCA at all. The terminal was packed and there was no place to sit. Coming home we rented a car and drove ourselves home, then returned it back to Dulles the next day (with someone to pick us up afterwards). It was a hassle, but since we only take 3-4 trips a year, it's not like we have to do it all of the time. As for someone posting that Jetblue doesn't fly out of Dulles, well they do, but they no longer offer non-stop flights to Florida out of IAD. In October we flew out of IAD on United (and I remembered why I didn't like United after that flight). But it was only 2 hours so we sucked it up. We had to pay for our bags, but we were trying all options. I just booked my January flights yesterday and again going to try the metro thing again. We booked the 1:00PM flight so that we can try to avoid some of the rush hour, though 270 is always rush hour no matter what time you take it. Since I spent 30 years of my life working in DC, metro was not a big deal for me, though my DH was amazed at how easy I made it seem. Again in January, we will most likely rent a car, but will just drive to Dulles and wait for someone to pick us up there. I know it sounds crazy, but since our trips are generally anywhere from 10-15 days, we just don't want to pay to park. I wish they would return to Dulles, maybe when the metro is finished they will come back. I was hoping another airline would start flying non-stops to Florida out of Dulles besides United.
