Ryanair Cancelled More Than 1,000 Flights in September, Here’s What You’re Owed When Air Traffic Control Is to Blame
Ryanair blamed UK air traffic control, Belgian strikes and Etna ash. The CAA says cash compensation is unlikely, but refunds, rerouting and hotels are not optional.

If Ryanair cancelled your flight in September because of air traffic control, you are very likely not owed cash compensation, but you are owed a choice of refund or rerouting and, while you wait, meals and a hotel. Ryanair reported more than 1,000 cancellations last month, and the UK Civil Aviation Authority’s guidance on the 8 September air traffic failure draws the same line.

Key facts
- Ryanair cancelled more than 1,000 flights in September 2026 out of 111,700 operated
- It carried 20.1 million passengers, up 4% on a year earlier
- Causes it cited: the 8 September Nats software fault, a Prestwick connectivity issue, Belgian ATC strikes and Etna ash
- CAA: compensation is unlikely for the 8 September disruption, but refunds, rerouting and care still apply
What caused the cancellations
Ryanair attributed the cancellations to two air traffic control problems within a fortnight, plus Belgian ATC strikes and volcanic ash from Mount Etna. The first was a software fault at the National Air Traffic Services (Nats) on 8 September. The second was a connectivity issue at the Prestwick centre in Scotland. Ryanair has joined calls for the Nats chief executive, Martin Rolfe, to resign, and Transport Secretary Heidi Alexander has scheduled meetings with the Nats chairman. We covered the second failure in our piece on Britain’s flight control failing twice in 13 days.

Why you probably will not get compensation
The CAA said of the 8 September disruption that passengers are unlikely to be entitled to compensation, because air traffic control failures are likely to count as extraordinary circumstances. It added that this is guidance, not a legal ruling, and you can still try to claim or go to court if you disagree. Our rule of thumb: an airline’s own staff strike or fault can pay out, an outside body’s failure usually does not.

| Distance | Amount |
|---|---|
| Under 1,500 km | £220 |
| 1,500 to 3,500 km | £350 |
| Over 3,500 km | £520 |
What the airline must still give you
Even when compensation is off the table, the CAA says airlines must offer the choice of a refund, rerouting at the earliest opportunity, or rerouting at a later date. They must also provide meals, refreshments and hotel accommodation proportionate to the delay. If they cannot arrange this, they should promptly reimburse the reasonable cost of your own arrangements. Keep every receipt. UK rules apply on any airline leaving a UK airport, and on EU or UK airlines arriving in the UK.

That is roughly one flight in 110. The odds are small, but over a 20-million-passenger month it still strands tens of thousands of people.
What to do if you are the one stranded
Ask for rerouting in writing, and ask about a flight on another airline if the next Ryanair seat is days away, since the CAA says other carriers may be offered where significantly faster. Book food and a hotel at a sensible price if the airline will not, and claim it back with receipts. A card paid flight can also give you a chargeback route if a refund is refused. If you booked travel insurance before the disruption, read the strike and air traffic clauses; see our guide to what airlines owe you when air traffic control fails.

What this means for you
Budget a buffer night before any long-haul connection. If you are flying out of Europe or the UK to Kathmandu, a Ryanair short hop feeding a Gulf flight is the weakest link. Book that leg a day early or on the same ticket as the long-haul.
