Paris CDG to Renumber All Terminals and Gates in March 2027

Paris Charles de Gaulle will renumber every terminal on 16 March 2027, and the gate-letter plan attached to it reverses the existing system at the airport's core Air France hub. Groupe ADP confirmed the scheme on its passenger site. The change touches every carrier at Europe's second-busiest hub, from Air France and its joint-venture partners to easyJet, the alliances and the low-cost carriers packed into the old Terminal 3.

The terminal renumbering itself is simple. Seven numbers replace today's fragmented layout:

• Terminal 1 (Star Alliance carriers) keeps its name.
• Terminal 3 (leisure airlines and ULCCs) becomes Terminal 2.
• Terminals 2A and 2C (largely oneworld) become Terminal 3.
• Terminals 2B and 2D (mostly easyJet and Air France partners) become Terminal 4.
• Terminal 2E (non-Schengen Air France and JV partners) becomes Terminal 5.
• Terminal 2F (Schengen Air France and partners) becomes Terminal 6.
• Terminal 2G (Air France regional flying) becomes Terminal 7.

More terminal numbers should help wayfinding. That is the defensible part of the plan.

What happens to the gate letters?

The gate scheme is where the logic frays. Today's Terminal 2 used lettered sub-terminals — A, B, C, D, F, G, and, for reasons never explained, K, L and M inside 2E instead of E gates. KLM does not use them. It operates from 2F.

The new plan gives every terminal lettered gates. In the new Terminal 5, the mapping runs backwards: today's M gates become B, L becomes C, K becomes D. The airport has inverted its own sequence.

Terminal 7, the regional operation, gets N gates — not A, and not on the north side. Groupe ADP's CDG 2035/2050 development vision explains part of it: T7 will eventually be demolished and replaced by a parallel concourse that will take the A letters. Why the A designation could not simply transfer with the terminal name, as N apparently will, the airport has not said.

Terminal 6 splits into E and F concourses — the E gates sitting in what is today Terminal 2F. Terminal 3 keeps only F gates; Terminal 4 divides between G and H. The split may track Schengen versus non-Schengen, but ADP has not confirmed that, and both current terminals mix the two flows. Some airlines will have to move.

The oddballs at each end

The new Terminal 2 — today's T3 — will use V gates. Some maps show P and V; official communications say only V will survive. The P may mark non-Schengen operations today, consolidated under a single letter. Why V was chosen is not documented.

Terminal 1, which today uses plain numbers with no letters, will split into R and S. The connected pier takes R for non-Schengen traffic; the satellites take S for Schengen operators such as Aer Lingus and Icelandair.

Assembled on a map, the pattern runs A-to-H from the southeast heading west, jumps to N, then leaps to R, S — and possibly V. The gaps suggest ADP is reserving I through Q for concourses that exist only in renderings: the 2035/2050 vision shows potential new midfield piers, and V may be a placeholder for a rebuilt Terminal 2 with T, U and a new V.

What does this change for airlines and passengers?

For airlines, terminal moves and gate re-lettering mean reprinted signage, re-briefed ground staff and updated booking systems before March 2027. For connecting passengers at a hub where misconnects already depend on bus rides between 2G and 2E, the risk is an 18-month window of confusion during transition. For ADP, the scheme buys a numbering framework that can absorb the 2035/2050 build-out without a second rebrand — the one clearly rational motive in the plan.

The airport has promised coherence. The gate letters so far do not deliver it, and ADP has published no rationale for the reversals, the N gates or the V.
