Terminal JEPPESEN-TERMINAL hosts 23 airlines. It's United Airlines's home turf at DEN.
Level 6 is departures, Level 5 is arrivals
Jeppesen Terminal is Denver’s single landside terminal, handling all check-in for airlines from United and Southwest to Aer Lingus, Lufthansa, and Turkish Airlines before everyone rides the underground train to Concourses A, B, or C. Level 6 holds ticket counters and check-in, while Level 5 holds baggage claim, international arrivals, and ground transport like RTD buses, rideshare pickup, and hotel shuttles.
A longtime DEN regular points out a simple orientation hack: look at the first digit on the door number. Doors starting with 5 mean Level 5, doors starting with 6 mean Level 6, which helps when you come out of an elevator on the north or south end and lose track of where you are. That trick matters because Jeppesen stretches more than 1,500 feet end to end, and it’s easy to burn 10–15 minutes just backtracking between doors and security zones.
Security checkpoints and the train to the concourses
All TSA screening for flights on carriers like American, Frontier, Alaska, JetBlue, and Volaris feeds through Jeppesen, then passengers take the underground train to A, B, or C. Regulars warn that the main checkpoints on Level 5 can produce lines that snake across the central hall and past multiple door banks, and TripAdvisor reviews mention waits that feel "insanely long" at early-morning and late-afternoon peaks.
Build the buffer. If you’re originating at DEN, 2 hours is the floor; on heavy mornings with big United and Southwest banks, 2.5–3 hours is smarter, because you still need 5–10 minutes to get down to the train and another 5–7 minutes to ride out to far gates like A81 or C54. If you’re connecting from a US domestic flight and get forced back to Jeppesen to re-clear security, assume 45 minutes just for TSA and the train ride back out.
Food and coffee before you ride out
Most restaurants sit in the concourses, but Jeppesen still gives you a few useful stops. Voodoo Doughnut sits on the mezzanine level on the northeast side of the terminal, just above the main Level 5 floor, and regulars grab a dozen pink boxes to bring into town before heading to baggage claim. Prices land in typical airport territory, with single doughnuts a few dollars each and specialty boxes higher.
Once you clear Jeppesen security and hit the train, your dining choices jump. In Concourse A’s center core you’ll see McDonald’s and Shake Shack facing each other, plus a Chick-fil-A kiosk not far away, all reachable within about 10 minutes of leaving the terminal. Further out, Breckenridge Brewery near Gate A71 and Aletitude near Gate A81 handle sit-down plates and local beer, while Coors Silver Bullet Bar near Gate C29 is the classic pre-flight beer stop for Rockies fans.
Concourse B and C options tie back to Jeppesen by that same train ride. Starbucks sits in the B Gates center core, reliable for a quick latte on a 15-minute leg between the terminal and a United gate on B East. Over in C, Auntie Anne’s by Gate C26, Santo near Gate C49, Bar Dough near Gate C54, and another Coors Silver Bullet Bar closer in at C29 soak up a lot of Southwest traffic during midday and evening waves.
Lounges you’ll reach after Jeppesen
No airline lounges sit directly in Jeppesen, so every premium cabin flyer starts in this terminal, then heads to a concourse. American passengers check bags with AA on Level 6, ride the train, then use the Admirals Club in the A Gates; Delta flyers do the same for the Delta Sky Club; and United travelers split between the United Club A Gates West and United Club B Gates East depending on departure gate.
Non-airline lounges tie into the same flow. The American Express Centurion Lounge and the Capital One Lounge (operated by Plaza Premium) sit past security in the concourses, not in Jeppesen itself, so don’t plan on a pre-check-in visit. US military travelers can use the USO Denver location airside as well, meaning you still have to clear one of Jeppesen’s checkpoints first on Level 5.
Shops, Global Entry, and ground transport
Shopping technically starts once you leave Jeppesen, but it’s worth knowing the brands you’ll hit. In Concourse A you’ll see Tumi and Kiehl’s for last-minute bags or skincare, plus an iStore and Hudson News near the A Gates for cables, snacks, and magazines under $20. That means if your carry-on dies at check-in with Aeromexico or British Airways in Jeppesen, you can still fix things after the train ride.
The Global Entry enrollment center hides in Jeppesen itself on Level 5, near the international arrivals zone on the north side, just east of the main arrivals doors. Frequent flyers time appointments to line up with inbound flights on carriers like Air Canada, Lufthansa, or Edelweiss, then walk a couple of minutes from baggage claim to the interview instead of making a separate airport trip.
Ground transport all feeds off Level 5. RTD’s A Line train into downtown Denver departs from the Transit Center under the south end of Jeppesen, airport hotel shuttles line up outside the Level 5 doors, and rideshare pick-up zones sit a short walk from the baggage claim carousels. One last tip: know your airline, head directly to Level 6 for departures or Level 5 for arrivals, and skip wandering the central tented hall until your bags and boarding pass are handled.
