Gate-side basics in T2
Terminal 2 at Don Mueang runs on grab-and-go, and FamilyMart is one of the few 24/7-style convenience options here once you’re airside. It’s in the domestic-focused terminal, so think Thai commuters, late-night buses, and early AirAsia runs all feeding through the same snack stop.
Prices track close to city branches: bottled water around 10–15 THB, canned coffee under 30 THB, onigiri and simple rice meals in the 30–50 THB range. That’s cheaper than most sit-down spots in DMK T2, and it keeps you under 100 THB for a quick breakfast plus drink without hunting the terminal.
You’ll find typical FamilyMart stock: triangle onigiri, packaged sandwiches, cup noodles, crisps, plus a few hot items in the warmer near the register. Expect basic Thai staples like pork floss bread and sausages on sticks alongside instant noodles you can hydrate using the in-store hot water dispenser.
Lines spike around the 06:00–08:00 and 18:00–21:00 departure banks in T2, when multiple domestic flights board at once. Figure on 5–10 minutes at the single main checkout during those peaks, and under 3 minutes in the quieter middle-of-day stretch.
Tip: grab water and snacks here before heading to distant domestic gates in T2; options thin out the farther you walk from the main central concourse cluster.
