Air traffic controller strike: how to check if your flight is at risk
You’ve just read there’s an air traffic controller strike and your plane departs tomorrow. Your heart races, you open Google and start frantically searching for information. But the news is confusing: which country is affected? Is your flight really at risk? And most importantly, what can you do?
ATC (Air Traffic Control) strikes are one of the most feared causes of cancellations and delays in Europe, especially in countries like France, Italy and Greece. In this guide we explain how they work, where to find reliable information and how to prepare.
How an air traffic controller strike works
Air traffic controllers manage air traffic within their country’s airspace. When they strike, the capacity of that airspace drops dramatically. The result:
- Flights departing from and arriving in the affected country may be cancelled or delayed
- Flights that fly over that country may be delayed due to route deviations
- The impact can extend to all of Europe due to the domino effect on traffic
A practical example: a French ATC strike doesn’t just affect flights to and from Paris. It can delay a Milan-London flight that crosses French airspace, or a Rome-Amsterdam flight that has to detour.
”Minimum services”
In many European countries, ATC strikes are subject to guaranteed minimum services, meaning a percentage of flights is still managed. In Italy, for example, controllers must guarantee a minimum level of service. This means your flight might not be cancelled, but the probability of delays remains high.
In France the situation is different: minimum services are less stringent and strikes tend to have a greater impact. It’s no coincidence that French ATC strikes are the most feared by European airlines.
Where to find up-to-date information
When it comes to strikes, sources matter. Here’s where to look:
Official sources
- EUROCONTROL Network Manager: the European air traffic management centre publishes bulletins on the expected impact of strikes
- Your airline’s website: when a strike is confirmed, airlines publish notices and offer free rebooking options
- National aviation authorities of the affected country (DGAC in France, DFS in Germany, AENA in Spain)
Informal but useful sources
- Travel forums and groups (FlyerTalk, dedicated Facebook groups): experienced travellers often share real-time information
- Airport social media accounts: some airports post flight status updates during strikes
- Local news from the striking country: they often have details that international sources don’t report
How FlightGuard monitors strikes
FlightGuard automatically collects news about strikes and disruptions from the GDELT database, one of the largest global news collections. When a strike event is detected, the “strike” factor in the risk calculation activates, increasing the risk score for potentially affected flights. This gives you a summary indication without having to trawl through dozens of sources.
ATC strike vs pilot strike: a crucial difference for your rights
Not all strikes are equal, and the difference has direct consequences on your wallet:
Air traffic controller strike (ATC)
- It’s considered an extraordinary circumstance under EU261 regulation
- The airline is not required to pay financial compensation (250-600 euros)
- You still have the right to assistance (meals, hotel) and rebooking or refund
Pilot or airline staff strike
- It is not considered an extraordinary circumstance (according to EU Court of Justice case law)
- The airline must pay EU261 compensation in addition to assistance
- Airlines often try to classify it as extraordinary: don’t accept this response
This distinction is crucial. If your flight is cancelled due to a Ryanair, easyJet or any other airline’s staff strike, you’re entitled to full compensation. If it’s cancelled due to an ATC strike, you’re not — but you still have the right to assistance and rebooking.
How to prepare for an ATC strike
If you know there’s a strike planned around your travel dates, here’s what to do:
In the days before
- Check flight status daily on the airline’s app
- Activate notifications from the airline to receive real-time updates
- Search for alternative flights proactively: if yours is cancelled, you’ll already know your options
- Prepare a plan B for transport: train, car hire, BlaBlaCar. For some routes (Milan-Rome, Paris-Lyon) the train can be a viable alternative
On the day of the strike
- Arrive at the airport on time, even if you fear cancellations. The flight might depart with a delay, and if you’re not there you lose your rights
- Bring everything you need for an extended wait: charger, snacks, an empty water bottle (to fill after security), a book
- Keep handy the airline’s customer service number
- Document everything: screenshots of schedules, communications, expenses
If the flight is cancelled
Follow the procedure described in our guide on what to do when your flight is cancelled. In short: contact the airline immediately (better by phone), request rebooking and keep all receipts.
Countries most at risk of ATC strikes
Not all European countries have the same propensity for controller strikes:
- France: the country with the most ATC strike days in Europe. French strikes have a huge impact because French airspace is the busiest on the continent
- Italy: frequent strikes but with more robust minimum services. The impact is generally more contained
- Greece: less frequent strikes but with significant impact, especially in summer
- Spain: less frequent, but when they happen they hit hard due to the large volume of tourist traffic
Countries like Germany, the Netherlands and the UK historically have fewer ATC strikes, though they’re not immune.
In summary
Air traffic controller strikes are a real risk for travellers in Europe, especially at certain times of year. The good news is that most are announced several days in advance, giving you time to prepare.
The key is staying informed, having a plan B and knowing your rights. And to monitor all the risk factors of your flight in one place — strikes included — there’s a tool designed precisely for this.
