What to know
The airside can vary by flight, so check the gate before entering security.
Airport layout
MCO has Terminals A, B and C. Terminals A and B share one main landside building and connect to numbered airsides by automated people mover.
Getting to the gate
At MCO, the A or B label identifies the landside check-in side; the airside number tells you which gate complex to use.
Connections
A and B passengers return to the shared main terminal between airside complexes, which can require another security screening.
