We flew out of DCA for the first time last month and had a pretty good experience. Our gate wasn't in the new, remodeled part of DCA, it was in one of the older annexes. The pros of that was a non-existent security line, but the downside was a lack of options for breakfast. Our flight out and coming back left on time.
Going out was the planes with three seats on either side, coming back was two and two. We did decide to upgrade to the extra legroom seats anytime we're scheduled to fly on the smaller planes, there's just not enough overhead bin space so getting to board early is a plus.
We also live less than 10 minutes from Dulles and had gotten very spoiled by the proximity, but as long as we can get early, nonstop flight down to MCO and a late, nonstop flight on the way back, we'll schlep to DCA. Plus, both our January and May roundtrip tickets were only $180 apiece.
