JetBlue regulars in Terminal C treat Potbelly as the default.
Right in Terminal C, this Potbelly Sandwich Shop is the quick, made-to-order option JetBlue folks mention when they skip Legal Sea Foods. It sits post-security in the main C concourse, so you can grab a sandwich on the way to those longer JetBlue and Mint departures. The vibe is standard chain, but predictable beats mystery when your boarding time is in 25 minutes.
Price-wise it lands in the $ tier: most hot sandwiches sit in typical Potbelly territory, cheaper than the sit-down spots near the C gates. Figure on a sandwich, drink, and cookie running less than many table-service entrées in the terminal. With a 3.5-star rating, expectations should be “solid chain food” rather than anything you’ll remember after landing.
Menu is standard Potbelly: hot sandwiches pressed on the line, basic salads, and those thick cookies that reviewers call out. No BOS-only specials here; you’re getting the same styles you’d find at a downtown Potbelly. Flyers on long-haul JetBlue Mint runs from C often grab something here to dodge relying on in-flight timing or just to have a backup sandwich in their bag.
What regulars do: they either mobile-order ahead or hit Potbelly immediately after clearing Terminal C security to beat the lines that build closer to prime evening bank times. Some admit to buying two sandwiches at once – one at the gate, one wrapped for cruise altitude. If your flight blocks out around 18:00–20:00, assume a line and plan accordingly.
Watch out for the downside of that rush. Multiple reviews mention missing standard toppings and staff not explaining substitutions, plus hot sandwiches sometimes coming out lukewarm when the queue spikes. If the line is ten people deep at C around 17:30, check your receipt and unwrap your sandwich before you walk away so they can fix misses on the spot.
Tip: if you’re on JetBlue in C with under 30 minutes to boarding, place a mobile order while you’re in the TSA queue and pick it up on your way to the gate instead of gambling on a last-minute walk-up.
