MCO Terminal B Guide: Airlines, Gates and Recovery
Read the airline, checkpoint and gate number as three separate pieces of information. A Terminal B label helps a driver find the right side of the building; it does not tell a passenger which security queue or Gate Link to use.

The answer first
Terminal B is one side of MCO’s main A/B building, not one post-security gate area. Airline check-in is on Level 3, baggage claim is mainly on Level 2, and the correct checkpoint depends on the flight: B airlines use both gates 1 to 59 and gates 70 to 129.
Navigation decision
Match the airline to the checkpoint, then verify the flight
Use this task-specific route, then follow current airport signs and airline instructions. The table does not replace a live gate assignment.
| Airline or situation | Landside label | Checkpoint or move | Gate or recovery rule |
|---|---|---|---|
| Alaska | Terminal B | Gates 1 to 59 checkpoint | Directory lists gates 30 to 39; confirm the current flight display. |
| American, United or Allegiant | Terminal B | Gates 1 to 59 checkpoint | Directory lists gates 30 to 59; each flight still has its own gate. |
| Breeze | Terminal B | Gates 1 to 59 checkpoint | Directory lists gates 1 to 29, illustrating why B is not a single airside. |
| Delta or Air Canada | Terminal B | Gates 70 to 129 checkpoint | Directory lists gates 70 to 99; follow the boarding pass and signs. |
| WestJet or Sun Country | Terminal B | Gates 70 to 129 checkpoint | Directory lists gates 70 to 99; recheck assignment before travel. |
| Dropped at A instead of B | Still landside in the A/B building | Go to Level 3 and cross to B | No interterminal vehicle is needed for the A to B landside crossing. |
| At the wrong security queue | Main building, before screening | Recheck the gate range, then walk to the correct checkpoint | Do not use the B sign alone as checkpoint evidence. |
| Already at a gate group | Past a security checkpoint | Ask staff before passing an exit | Paired gate areas may connect, but crossing to the other checkpoint group requires rescreening. |
| Flight actually leaves from C | Separate terminal building | Use Terminal Link or the B65 terminal shuttle | Allow for the landside transfer and the C departure checkpoint. |
Recover the plan
Wrong-side recovery in four decisions
Only the A/B letter is wrong
Remain landside and cross on Level 3.
The checkpoint range is wrong
Reconfirm the gate, then choose the correct entrance before security.
Already through security
Ask staff about the permitted paired-area route before crossing an exit.
The flight is at Terminal C
Treat it as a building transfer with another departure screening.

Why a B airline can use either end of the building
MCO’s current directory places American and United on the B side with the gates 1 to 59 checkpoint, while Delta and Air Canada use B with the gates 70 to 129 checkpoint. Those are different security choices despite sharing a terminal letter. MCO airline directory
Use the table as an orientation example, then check the live directory and boarding pass for the day’s flight. The gate display controls a last-minute change; a screenshot of an old airline list can send a passenger toward the wrong train. MCO airline directory
Codeshares deserve an extra check. Find the airline actually operating the aircraft, use its check-in instructions and compare its terminal assignment with the airport display instead of relying only on the airline whose website sold the ticket.
If the boarding pass lacks a gate or conflicts with a directory entry, ask the carrier before entering a queue. Settling the question beside check-in is easier than correcting it after screening or riding to a gate area.
Three levels, three different jobs
Level 3 is the B-side airline check-in floor and the place to cross landside between A and B. If a driver uses the A curb by mistake, the airport instructs passengers to return to Level 3 with their bags and walk across the building. MCO terminal maps · MCO getting around
The airport map lists B-side baggage carousels 20 to 32 on Level 2. Check the flight-specific carousel display before waiting; luggage delivery is an arrival task, separate from choosing a departure checkpoint. MCO terminal maps
Level 1 includes bus, shuttle and rental-car facilities. Rideshare pickup can depend on current airport instructions and time of day, so use the app and signs for the actual assigned level rather than directing every driver to Level 1. MCO terminal maps
For a meeting, send a precise location such as terminal, level and marked door or carousel. An airline logo, a generic arrivals sign or “by the train” can describe several places, so confirm a location that both people can actually reach.
Recover without adding an unnecessary security trip
First determine whether the mistake is only the landside A/B side. Both letters belong to the same main building, and the airport’s Level 3 crossing solves that problem without a shuttle or a trip to Terminal C. MCO getting around
If the issue is a checkpoint, match the flight’s gate range to the signs before screening. The Gate Link people movers serve gate areas after the checkpoint; they are not a universal route between every flight at MCO. MCO getting around
MCO describes access between paired areas, gates 1 to 29 with 30 to 59, or gates 70 to 99 with 100 to 129. That transfer depends on remaining in the permitted secure circulation rather than passing the exit into the public terminal. MCO getting around
International-arrival handling can interrupt that paired-area access and require another screening. Ask airport staff about the current route before leaving the Gate Link platform, especially if the next flight boards soon or the plan depends on visiting a lounge. MCO getting around
When the onward flight is in Terminal C
Terminal C is a different building. From the B side, the airport describes Terminal Link access in the Level 3 East Hall / Hotel Atrium area, with the train arriving at the station connected to C by the Garage C walking route. MCO getting around
The other published option is the terminal shuttle from B65 on B Level 1 to C272 on C Level 1. Both terminal-transfer services are listed as running 24 hours, but walking, waiting and any assistance needs still belong in the connection allowance. MCO getting around
Check the bag tag and airline instructions before moving buildings. An onward journey on separate tickets may require another check-in, and a same-reservation connection can still have itinerary-specific requirements for international luggage.
If a vehicle, rental car or hotel shuttle is meeting the arriving flight, confirm the arrival terminal with the provider. A departure from B and return to C can create a parking or pickup mismatch even when the airline booking itself is correct.
Keep the boarding clock in charge
MCO recommends being at the security checkpoint two hours before departure. Add the time required for the B-side counter, baggage deadline and the journey to the terminal; the airport recommendation is not a promise about the length of the security line. MCO security guidance
A PreCheck indicator or a reserved screening slot does not change the flight’s gate group. Choose the correct checkpoint first, then follow the lane instructions that match the boarding pass and the service actually operating. MCO security guidance
For wheelchair assistance, contact the airline in advance and describe any terminal change. Keep the party together until the route and handoff are clear; luggage and a mobility device can turn a seemingly simple wrong-side correction into several separate tasks. MCO getting around
Find the departure gate before committing to a sit-down meal or shopping detour. If time is tight, the useful recovery question is what remains before boarding, not whether another terminal has a better amenity.
Traveler questions
Terminal questions
Are Terminal A and Terminal B separate buildings?
No. MCO describes them as opposite sides of the same building, connected landside on Level 3.
Does every Terminal B airline use gates 70 to 129?
No. The current directory assigns several B airlines to the gates 1 to 59 checkpoint, including American and United.
Which checkpoint does Delta use at MCO?
The checked directory lists Terminal B and the gates 70 to 129 checkpoint for Delta. Confirm the current boarding pass and airport display.
Can I walk from the B side to the A side?
Yes, landside on Level 3. If starting on Level 1 or 2, the airport says to take the bags back up to Level 3 to cross.
Can I change gate areas without security again?
Some paired gate areas can be reached while staying in secure circulation. Airport restrictions or an exit to the public terminal can require screening again, so ask staff before exiting.
Is the Terminal Link the same as a Gate Link?
No. The Terminal Link connects the main building with the Train Station for C, while Gate Links carry passengers to the main building’s gate areas.
