Footlongs at Gate C2 when you want cheap and customizable
This Subway sits post-security at Gate C2 in Concourse C, and it’s one of the few IAD spots where you can still point at the veggies and build a made-to-order sandwich without paying $18. Price tier is firmly $, and the rating hovers around 3 out of 5, which lines up with “standard mall Subway” expectations.
You’re right at the head of the C concourse, near Potbelly and several United gates, so lines spike whenever a couple of flights dump at once. Reddit regulars mention they hit it outside the 11:30–13:30 and 17:30–19:30 rush if their connection is longer than 45 minutes. The space itself is tight, and Google reviews call out a cramped ordering lane that clogs easily when six or seven people queue.
Menu is the usual national setup: Veggie Delite, turkey subs, and the standard cold cut and tuna lineup. Multiple reviewers flag the Veggie Delite and plain turkey as the safest bets on days when quality feels hit-or-miss. Expect typical airport upcharge, but still under $10–$13 for a basic footlong, which is cheaper than most hot options nearby.
Watch out for supply issues later in the day: several comments mention running out of Italian herbs and cheese or wheat bread after 19:00, and sometimes key toppings disappear too. Staff pace can be slow when they’re restocking, which turns a 5‑minute stop into 15, so don’t cut it close for a C or D gate departure boarding 30 minutes before wheels up.
What regulars do: order one footlong, have it sliced into two 6‑inch halves, eat one at the C2 seating area, and bag the other half for a transcon or overnight. If you’re walking over from B gates via the AeroTrain, add 10 minutes each way and aim to hit Subway at least an hour before a long-haul boarding time.
