What Terminal Is Delta at MCO? Gates, Check-In, and the Fastest Way Through

I spent twelve years working Delta gates down at Atlanta, so when someone asks me where Delta lands at Orlando, I don’t have to look it up. Here it is, straight.

The Quick Answer: Terminal B, Airside 4, Gates 70-99

Delta flies out of Terminal B at Orlando International Airport (MCO). You check in on the Terminal B side, clear the security checkpoint that serves gates 70-129, and board from gates 70-99 — the Airside 4 satellite concourse. That’s the answer to the exact question you typed. According to MCO’s own airlines page, Delta also runs curbside check-in at the Terminal B departures curb, which is worth using if you’re only dropping bags.

Now the part the brochure pages skip: gates 70-99 are not attached to the building where you check in. Airside 4 is a remote pod. The only way to reach it is a short tram ride after security — nobody walks to a Delta gate at MCO. More on that tram in a minute, because right now it’s the single most important thing to know about flying Delta out of Orlando.

Terminal B Layout: What’s on Each Level

Terminal B stacks three levels, and once you know which one does what, the building stops feeling like a maze.

Level 3 — Check-In and Departures Curb

Everything starts on Level 3. That’s the departures level: Delta’s ticket counters, the curbside check-in podium, the self-serve kiosks, and the security checkpoint all live up here. Drop-off traffic pulls to the Level 3 curb. Once you’re screened, your boarding gate is on this same secured level — you just ride out to it.

Level 2 — Bag Claim and TSA PreCheck Enrollment

Landing instead of leaving? Delta’s baggage claim is on Level 2, carousels 20-32. Watch the arrivals boards for your number. Level 2 also holds something most travelers walk right past: a TSA PreCheck Enrollment Center near baggage claim 23, open Monday through Friday, 8am to 1pm and 1:30pm to 4:30pm. If you’ve been meaning to sign up, that’s the spot.

Level 1 — Ground Transportation and Rental Cars

Ground transportation is the bottom level. Taxis, rideshare pickup, rental car counters, and the hotel and resort shuttles all stage on Level 1. Tell whoever’s collecting you “Terminal B, Level 1,” and have them wait in the cell phone lot until your bag is actually in hand. If you’re driving yourself, here are parking options near Terminal B.

Delta Sky Club at MCO: Where It Is and When It’s Open

Good news for Sky Club members: the lounge is right in your airside. The Delta Sky Club at MCO sits in Terminal B, Airside 4, in the Center Atrium near Gate 71 — so once you step off the tram, you barely have to walk. One rule to plan around: per American Express, access is limited to within three hours of your departure. If you’re on a layover as a cardmember, that window doesn’t apply to you. Everyone else should time their arrival so they aren’t turned away at the door for showing up too early.

How Delta’s Check-In Cutoffs Actually Work at MCO

This is where people get burned, so let me be precise. Delta changed its rules on April 8, 2025.

• Domestic with a checked bag: checked in at least 45 minutes before departure. That’s up from the old 30-minute rule, per AFAR — an extra 15 minutes that catches a lot of returning vacationers off guard.
• Domestic with no checked bag: 30 minutes before departure.
• International: 60 minutes before departure. MCO isn’t on Delta’s list of extended-cutoff airports — the ones like JFK that require 90 minutes — so the standard 60 applies here, according to Frommer’s.
• Everyone, every flight: be at the gate ready to board 15 minutes before departure.

Miss the check-in cutoff and it doesn’t matter how short the security line is — the system won’t take your bag. Treat these as hard deadlines, not suggestions.

Heads Up: Construction Is Disrupting the Tram to Delta’s Gates

Here’s the thing no competing page will tell you, and it’s the reason I’d pad your timing right now.

On December 3, 2025, MCO started a $253 million Gate Link Replacement Project that runs through Fall 2027, according to reporting from Spectrum News 13. It’s rebuilding the trams that carry passengers out to gates 70-129. The airport upgraded Southwest’s gates (100-129) first, for about a year — and after that, the work moves to gates 70-99. That’s Delta’s airside.

Normally the Gate Link ride out to your Delta gate is nothing: 1 minute 30 seconds each way, with a 40-second pause at each station. The original system dates to 1990 with cars replaced in 2008, which is exactly why it’s being replaced now. During construction, though, only one of the two trams on an airside runs during the day. That adds a few minutes even at peak times — survivable if you know it’s coming. The part that bites: from roughly 11pm to 4am, both trams on an airside can shut down entirely, and you’ll be routed onto a 24/7 shuttle bus instead, per travelers tracking the work at Practically Perfect Pixie Dust. If you’ve got an early-morning or red-eye Delta flight, build in the extra time for that bus.

How Early to Arrive for a Delta Flight at MCO

Because of the tram work, MCO is pushing a simple “3-2-1 rule” right now: be at the airport 3 hours before departure, through security 2 hours before, and at your gate 1 hour before boarding. That’s not padding for its own sake. Chase Travel ranks MCO as the third-longest security wait among major U.S. airports, and the construction only tightens things.

Outside of construction, GOAA — the authority that runs MCO — sets its baseline at 2 hours to the security checkpoint, and tells you to confirm the specifics with your airline. My honest read as a former gate agent: for an ordinary weekday morning, 2 hours is fine. For a holiday, a weekend, or any early flight while the tram work is on, take the airport at its word and give yourself the full three.

Flying In From Abroad? Where Global Entry Is on Delta’s Side

If your Delta flight arrives internationally into gates 70-99, you clear immigration before you touch baggage claim. At MCO that happens on Terminal B, Level 3, over on the B side of the terminal — that’s where the Global Entry kiosks and passport control sit for Airside 4 arrivals. Clear there first, grab your bag on Level 2, then head down to ground transport on Level 1.

Delta vs. Terminal A: How MCO’s Layout Compares by Airline

Delta is a Terminal B carrier. The airlines travelers most often mix it up with check in over on the Terminal A side of the building — but only one of them is cleanly separate from Delta’s gates. Southwest flies out of Terminal A from gates 100-129 in Airside 2, its own checkpoint, well clear of anything Delta touches.

Frontier is the one that trips people up. Frontier’s gates are also in Terminal A for check-in, but Frontier is split across two different checkpoints: some flights leave from gates 1-29, and others board from gates 70-99 — the very same Airside 4 pod Delta uses. So don’t assume a Frontier gate is nowhere near a Delta one at MCO; out on the 70-99 side, the two airlines share the concourse. Southwest, over at 100-129, really is a separate airside.

Here’s the reassuring part on the terminal itself: Terminal A and Terminal B aren’t separate buildings. They’re opposite ends of the same one, only about 525 feet apart. You can cross between them — but only on Level 3, the departures level. If you’ve already ridden down to Level 2 or Level 1, you have to go back up to Level 3 to cross. That matters if you’re dropping off or picking up a companion flying a different airline than you.

One more that trips people up: Terminal C. MCO moves nearly 58 million passengers a year across three terminals, and Terminal C is the newest, reached by the Terminal Link tram and a walk of roughly 1,200 feet through Parking Garage C. It’s for international and leisure carriers like Aer Lingus, British Airways, Emirates and JetBlue — not Delta. If you booked Delta and you see signs for Terminal C, they’re not for you.

Delta at MCO: Quick Answers

Is Delta in Terminal A or B at MCO? Terminal B. You check in and clear security on the Terminal B side, then ride the Gate Link tram out to Airside 4, gates 70-99.

Which airlines are in Terminal B at MCO? Terminal B feeds Airside 4 (gates 70-99), where Delta boards. You check in on the B side and screen at the checkpoint serving gates 70-129.

What airlines use Terminal A at MCO? Southwest and Frontier both check in on the Terminal A side. Southwest boards from gates 100-129 in Airside 2 — a clean, separate airside from Delta. Frontier is the split one: it’s spread across two checkpoints, gates 1-29 and gates 70-99, and that second range is the same Airside 4 Delta uses. So Terminal A isn’t entirely walled off from Delta’s gates the way people assume.

Is Delta Terminal 3 or 4 at MCO? Neither. MCO uses lettered terminals, not numbered ones. If you’re coming from JFK or LaGuardia, where Delta lives in numbered terminals, that’s the mix-up. At Orlando, Delta is Terminal B, and it boards from Airside 4 (gates 70-99). The “4” is the airside, not the terminal.

How early should I get to MCO for a Delta flight? Two hours to security on a normal day; the full three the airport recommends during the current tram construction, on holidays, or for any early departure.
