Orly Airport Terminals Explained: Orly 1, 2, 3 & 4 (2026 Guide)

Short answer: Paris-Orly has four halls — Orly 1, 2, 3 and 4 — that together form one connected terminal building. Halls 1, 2 and 3 occupy what used to be called Orly Ouest (West), and Hall 4 is the former Orly Sud (South). They’re joined by internal walkways, so you can move between all four on foot without leaving the building. Which hall you use depends on your airline and destination, shown on your boarding pass and the airport’s departure boards.

TL;DR — Orly terminals

• 4 halls: Orly 1, 2, 3, 4 — all connected, one building.
• Halls 1–3 = former Orly Ouest; Hall 4 = former Orly Sud.
• Your hall depends on your airline/destination — check your boarding pass.
• Connected to Paris by Metro Line 14, Orlyval + RER B, Tram T7, RER C, Orlybus, taxi.
• Arriving or departing? A fast-track service speeds you through the busy control points.

How Many Terminals Does Orly Have?

Orly has one terminal building divided into four halls: Orly 1, 2, 3 and 4. This numbering came from a reorganisation that retired the old “Orly Sud” and “Orly Ouest” names in favour of a single sequential system. The practical takeaway: you won’t catch a shuttle between separate buildings the way you might at a larger hub — the halls are internally connected, and walking from one end to the other is straightforward, if a little long at the extremes.

Which Orly Terminal for My Flight?

Your hall is determined by your airline and route, not by a rule you can memorise — airlines are assigned to halls and can occasionally shift. The reliable sources are:

• Your boarding pass — it states your hall and gate.
• The airport departure boards — confirm on the day, in case of changes.
• Your airline’s check-in area — signage directs you to the right hall.

Here’s the general layout to orient yourself:

Because assignments change, always confirm your specific hall on your boarding pass rather than relying on a fixed map. The good news: since the halls connect, ending up at the wrong one isn’t a disaster — just a walk.

How Are the Orly Terminals Connected?

All four halls link through the building’s central area, so transfers and corrections are done on foot. This matters most for two groups:

• Connecting passengers — your transfer is usually a walk between halls rather than an inter-terminal train ride. (See our full guide to connecting flights at Orly.)
• Anyone who’s unsure of their hall — you can move freely landside between halls to reach the right check-in area.

The connected layout is one of the things that makes Orly easier to navigate than larger, multi-building airports — once you’re inside, everything is reachable without leaving.

Getting From Orly to Paris (and Back)

Orly connects to central Paris through several options. Pick based on your budget, luggage, and how fixed you need your travel time to be:

For arrivals especially, having your onward transport sorted before you land removes a decision point at exactly the moment you’re most tired — which pairs well with a meet-and-greet arrival service.

Making the Terminal Experience Smoother

Knowing your hall is half the battle; the other half is the control points — security on the way out, passport control on the way in. These are where time disappears, particularly at peak hours and on non-Schengen routes. That’s where fast track changes the day:

• Departing from Orly? A departure fast-track lane gets you through security via a priority queue, whichever hall you’re flying from.
• Arriving at Orly? An arrival fast-track greeter meets you at the gate and walks you through priority passport control to the exit.
• Connecting through Orly? A connection fast-track escort handles the transfer between halls and any re-checks.
