Paris Orly's Runway Closure Is Rerouting Flights to CDG

Paris doesn't usually make you choose an airport. You land, you leave, you forget the runway number existed. Not this year. Runway 4 at Orly closed on 10 August 2026 for repaving and won't reopen until 17 December, and Aéroports de Paris has already rerouted or cancelled roughly 3,000 flights because of it. If your ticket says Orly and your travel dates fall anywhere in that window, the airport on your boarding pass may not be the one you actually land at. This isn't a strike day that resolves itself by evening. It's a four-month capacity cut, and it behaves differently — and it's the kind of detail that never makes it into the blog post ranking for "best time to visit Paris."

ℹ️ Orly's Runway Is Down Till December

Runway 4 at Paris Orly shut on 10 August 2026 for repaving and reopens 17 December — about 3,000 flights are being cancelled or moved to Charles de Gaulle in the meantime. Check your airline's app before you lock in a hotel or transfer near Orly.

Aéroports de Paris, which runs Orly, confirmed the runway works would begin 10 August and finish 17 December 2026 — pavement renovation, taxiway redesign, and new ground lighting across 3,350 metres of surface, plus seven taxiways and an access junction. That's not a maintenance window you route around with a delay. It's a reduction in how many aircraft the airport can accept, full stop, which is why the affected-flight count is measured in thousands rather than dozens.

easyJet, one of Orly's largest operators, said its own cancellations run from 10 August through 24 October, with alternate flights offered to customers. Other airlines are working through their own schedules on their own timelines — one carrier's cutoff date isn't a guarantee for anyone else's ticket. If you're flying Orly before mid-December, the honest answer to "will this affect me" is: check your specific airline, not the news.

There's also a meaningful difference between a cancelled flight and a diverted one, and it changes what you're owed. A cancellation usually comes with a rebooking offer or a refund. A diversion to CDG means your flight still happens — you just land somewhere else, and the airline's obligation to help you get from CDG to your actual destination is a separate conversation you may have to start yourself. Read the actual wording of your schedule-change notice before assuming either outcome.

Leisure travellers on low-cost, short-haul European routes into Orly are the most exposed group, simply because that's where the airport concentrates its schedule. French domestic and Maghreb-route carriers face the same compressed runway capacity even when their name isn't in the first headline about it.

The traveller with the genuinely awkward version of this is someone who booked an Orly-to-Orly connection — arriving on one flight, departing on another, both from the same terminal. Orly and Charles de Gaulle are not a quick airside walk apart. If one leg of your trip gets moved to CDG and the other stays at Orly, you're now budgeting an inter-airport transfer you never planned for, on a schedule you didn't choose.

Most Indian travellers land in Paris on a direct long-haul into CDG to begin with, so this closure rarely touches the India-to-Paris leg itself. Where it bites is the layer most itineraries add on top — a budget hop to Nice or Barcelona, a quick loop into Lisbon, the kind of intra-Europe leg that gets booked separately and cheaply, often specifically through Orly because the fares there undercut CDG. If that describes any part of your route, that's the segment to open your airline app for, not the transatlantic or India leg.

If you're only passing through France on a Europe leg — say, a Paris stop inside a longer Euro trip itinerary — the fix is usually simpler: build the transfer time in now, before the airline forces the question on travel day.

⚠️ Don't Book Non-Refundable Orly Hotels

A flight that shows Orly on the day you booked it can still move to CDG, get cancelled, or shift by several hours before you fly. Hold off on non-refundable stays near Orly South or West until your airline has confirmed which airport you're actually using.

A strike usually resolves within a day and the original schedule comes back. A four-month runway closure doesn't work that way — airlines trim frequencies, consolidate departure banks, and shift residual flights to CDG in stages as the works period runs its course. That means your itinerary can change more than once between booking and departure, not just on the day. And capacity doesn't necessarily snap back on 18 December either — winter demand can outrun a schedule that's still being rebuilt, so a late-December or January Orly booking deserves the same weekly check as one in September.

The rule of thumb: if any leg of your trip touches Orly between now and well into the new year, open your airline's app once a week, not just the night before. It costs nothing, and it's the only way to catch a schedule change early enough to actually do something useful with it — rebook a hotel, adjust a transfer, or just stop worrying about a leg that turned out fine. Keep a screenshot of your original itinerary and any change notice too; it's the kind of paper trail that matters if you end up asking an airline to honour a rebooking or refund.

Vani can search live flights into both Orly and CDG side by side, so you can compare an Orly-routed itinerary against a CDG one on total trip cost — fare, transfer time, and the taxi or RER ride into the city — rather than just the ticket price. That total-cost comparison matters more than usual right now, because the cheapest fare into the wrong airport can quietly cost you more once you add the transfer.

I've seen this pattern before with flight comparisons generally: a traveller books the ticket that's ₹3,000 cheaper, the layover eats four hours in an airport with no lounge, and the saving evaporates before they land. A runway closure just adds a second version of the same trap — the fare looks fine until you price in getting from CDG to your actual hotel. If your trip also needs a hotel rebooked closer to whichever airport you actually land at, Vani can pull live availability for that too, filtered by distance to the airport rather than just star rating.

What Vani can't do is call your airline for you, sit on hold on your behalf, or guarantee a specific rebooking outcome — that decision, and the final booking, stays with you. Nine times out of ten the airline's own app has already made the decision for you by the time you check; Vani's job is making sure you notice before it becomes a same-day problem. If your plans are already this complicated, you can also talk to a human expert on WhatsApp once you've got the essentials sorted, or start the comparison yourself with G8Trip's trip planner.

The runway will get fixed. Your itinerary, in the meantime, is your problem to manage — the airport isn't sending you a personal apology note, just a schedule-change email you have to actually open.
