it’s actually really hard for private jets / charter (whether part 91 or part 135) to use dca. requirements include having an armed officer on board. as a result almost nobody flies charter into dca.
Yeah, it's at least partially Congress's fault DCA is as busy as it is. Every few years, they push to allow more flights, and longer flights, into the airport, because they all want to convenience.
Which is silly, it's not like IAD is all that far away. It's a straight shot down the Access Road to 66 and then into the city. Of course, with the RTO mandate, the portion from 66 inward is going to get busy again, but hey, Congress wanted that too, so reap what they sow, I suppose.
DCA is much nicer in pretty much all respects other than having a fairly restricted set of routes. When the routes are available, I’ll pick DCA every time. It’s a gem, and I’m glad that Congress’ selfishness overrode their terrorism paranoia on this one.
That's true, DCA is smaller footprint, so easier to navigate inside. And even better now that the remote terminal redone and linked properly (vs the old "Take a bus and wait on a bench").
But, the last few years, I haven't had any issues at IAD. Yeah, it takes longer to get from the front door to the gate, but that's about it. The security lines are more reasonable now (pre-COVID they were pretty long at times).
I pick IAD when I can, but that's only because I live in Reston. If I lived inside the Beltway, I'd pick DCA, but only because of the shorter drive, not the airport experience itself.
And I wouldn't want DCA to be shuttered. But, it's been at capacity for a while and Congress keeps pushing that limit.
Also DCA is the most popular airport and congress would stage their own revolution if they had to go further.
