Flying Allegiant or Sun Country into Orlando for a Disney or Universal trip? Starting Thursday, Oct. 29, both airlines check in and claim bags at MCO’s Terminal A.
If you’re flying Allegiant or Sun Country to Orlando this week, don’t follow your old habits at the airport. Starting Thursday, Oct. 29, both airlines are moving from Terminal B to Terminal A at Orlando International Airport.
The airport announced the switch on X on Wednesday, Oct. 28, and tagged both airlines. “Please plan accordingly & safe travels!” the post said.
That’s a small change on paper. But anybody who’s dragged a stroller, two car seats and a cranky toddler across MCO knows the wrong side of the building can feel like a whole extra park day.
Here’s a spring tour of Terminals A and B from Poko Traveler, so you know what you’re walking into:
Where do Allegiant and Sun Country check in at Orlando airport now?
Per the airport’s post, here’s the new setup starting Oct. 29:
Check-in: Level 3, Terminal A
Baggage claim: Level 2, Terminal A
Sun Country gates: 1-29
Allegiant gates: 30-59
WDW News Today was first to share the change, and it said both airlines currently run out of Terminal B. The airport didn’t give a reason for the move.
Is Terminal A the same building as Terminal B at MCO?
Yes, more or less. Terminals A and B are the two sides of MCO’s main terminal building, the older one with the hotel and the big atrium. Terminal C is the separate, newer terminal on the south side.
So you’re not going to a different building. You’re going to the other side of the same one, and that still matters when you’re picking a drop-off spot or telling your ride-share driver where to go.
The bigger risk is baggage claim. Level 2 of Terminal A is where your bags will show up, so head there when you land instead of drifting over to B out of habit.
Why does MCO keep changing things?
Orlando International is in the middle of a big makeover. The airport’s $6.9 billion Capital Improvement Program is paying for a lot of it, including new Gate Link trams.
The first of four new trams entered service on Oct. 2, serving Gates 100-129, per WDW News Today, which quoted the Greater Orlando Aviation Authority. Each new tram carries up to 240 passengers, and the project costs $253 million.
GOAA CEO Lance Lyttle put it plainly back then: “we are building an airport for the future, and this Gate Link milestone brings that vision to life.” The airport has also said it plans a new baggage system for Terminals A and B by 2030.
How busy is Orlando International Airport?
Very. MCO handled 57,675,573 passengers in 2025, up from about 57.2 million in 2024, according to the airport’s July 28 press release.
That makes it the busiest airport in Florida and the seventh-busiest in the U.S., up from ninth the year before. It ranked 25th in the world.
“These numbers are reflective of Central Florida’s continued growth and global appeal,” Lyttle said in that release. Translation: a lot of people want to see the mouse, the wizard and the beach.
Are Allegiant and Sun Country the same airline now?
They’re still flying under separate names. Allegiant announced a deal in January to buy Sun Country for about $1.5 billion, according to WFTV.
At the time, WFTV reported the airlines would keep operating separately and there’d be “no immediate changes to flights, tickets, or scheduling.” Neither the airport nor the airlines tied this week’s terminal move to that deal.
Both are budget-friendly options for Disney and Universal fans coming in from smaller cities. Allegiant started flying out of MCO in 2024 after years of using Orlando Sanford, ClickOrlando reported in 2023.
What should Disney World guests do differently at MCO?
Check your airline before you leave home, and double-check the night before. Then tell your driver “Terminal A” if you’re on Allegiant or Sun Country after Oct. 29.
If you’re riding a resort shuttle or a car service, send them the change too. Drivers who’ve dropped off at B for months may not have gotten the memo yet.
And leave a few extra minutes. New signs, new check-in lines and a holiday travel season about to kick off are a recipe for a little confusion on the curb.
