Yeah 16 minutes from Metro arrival to boarding is maybe a bit too close. You're relying on Metro to be very on time at that point. But it'd be interesting to see how long it actually takes you. My experience with the early TSA line at DCA is smooth even in the non-precheck line, and none of the gates are a long walk.

Edit: and especially since your plane isn't coming from somewhere else, there's no turnaround time for the plane to be cleaned and refueled. It's a high likelihood of leaving on time or even earlier.

Does the flight depart at 630 or begin boarding at 630? If its the later metro is probably ok, but if your boarding starts at 6:00 then probably need to take an Uber.

Thanks /u/thanks-_- !

I'm out of the loop, can anyone explain?

If you are athletic at all (or not), sign up for a local 5k turkey trot! They are a fun and good way to burn off that pumpkin pie.

As long as it is not spikes, you are ok.
