The gate stands at DCA installed a few years ago listed “Bxx,” such as B17. Here’s why:

Terminals will adopt alphanumeric gate terminology to better guide travelers

Beginning June 4, Ronald Reagan Washington National Airport (DCA) will update signage throughout its terminals, roadways and parking areas to make it easier for passengers to navigate the newly expanded facilities and more closely align with terminology used at other major airports. Upon installation, the new sign package will simplify passenger travel from curb to gate.



The timeline of changes includes:

• Weekend of June 4-5: Passengers will see enhanced directional signs inside the airport leading to airline gates.
• Sunday, June 5: All airlines will begin displaying enhanced terminal and gate names on flight information screens and boarding passes.
• Week of June 6-10: Road signs leading to terminals and parking garages will transition from Terminals A, B and C to Terminals 1 and 2.

During the weekend change-over, gate numbers will remain the same, with the addition of each gate’s concourse before the number. For example, Gate 23, located in the newly named Concourse C, will become Gate C23. The new concourse that opened in 2021 will be named Concourse E, including Gates E46-E59. Signs throughout the airport will reflect the change, and airlines will begin using the alphanumeric gate designations on boarding passes and flight information screens on Sunday, June 5. While no gates are relocating and no airlines are moving, passengers are advised to check their boarding passes and in-airport monitors to confirm their gate assignments.

The following week, June 6-10, DCA will update signage outside the terminal buildings and along airport roadways and Metro station entrances to reflect new terminal names. The current Terminal A will become Terminal 1. It will contain Concourse A, serving Southwest, Air Canada and Frontier airlines. The current Concourse B/C will be renamed Terminal 2 and will contain Concourse B, serving Delta, United and Alaska airlines; Concourse C serving American and JetBlue airlines; and Concourses D and E, serving American flights.

Seems to be opposite of the new LGA gate naming/numbering strategy. I like the letter designating the concourse.

So what are DL's gates in the new system?

Billy Mumphrey

The same as in the old system, since the B concourse didn’t change letters. I believe they’re B15, 17, and 19-22.

Correct, and sometimes Gate B18, which is DL/AS shared.
