Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at DAY handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Concourse A is the larger of DAY's two concourses, with 12 gates (numbered in roughly the A11–A24 range) reached from the main terminal via a short walkway past the single central security checkpoint. It handles the bulk of American, Delta, and United departures. On-concourse amenities include the 12th Fairway Bar and Grill near Gate A15, the Wright Stop TravelMart newsstand near Gate A20, gate-hold seating with built-in power outlets, and companion-assisted restrooms.
Concourse B has 8 gates (numbered up through roughly B14) and is reached from the same central terminal area as Concourse A, on the opposite side of the shared checkpoint. Allegiant and a mix of mainline carrier flights use this concourse depending on schedule. Amenities include MVP Bar & Grill, a nearby Quiznos, a post-security Dunkin' location, the Dayton Marketplace newsstand near Gate B14, and the Airport Police / Lost & Found office.
DAY is one compact terminal building — Concourse A and Concourse B both connect directly to the main terminal on either side of the airport's single central security checkpoint, so there is no train, tram, or airside shuttle between them. The full walk between the two concourses takes well under 10 minutes.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at DAY — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
Head to the main terminal (not a specific concourse) for check-in and the one central security checkpoint; after screening you'll reach a shared pre-gate area with signage directing you to Concourse A or Concourse B gates — there is no wrong checkpoint to use since both concourses share the same one.
A few habits that prevent last-minute sprints:

Look for departure boards throughout the terminal for real-time gate information.
