CAA sets out if passengers get payout after Monday delays

Following heavy disruption to flights on Monday, the UK Civil Aviation Authority (CAA) has outlined when passengers affected by widespread airport delays may be entitled to compensation and when airlines are only required to provide care and refunds.

What happened on Monday and who was affected

Large numbers of flights departing from and arriving into UK airports on Monday were delayed or cancelled after an operational incident affected air traffic and airport operations. Published coverage indicates that thousands of travellers faced missed connections, overnight waits and abandoned trips as airlines adjusted schedules and reduced capacity.

Publicly available information shows that, in situations like this, delays often arise from a combination of air traffic flow restrictions, airport system outages and subsequent knock-on effects as aircraft and crews are left out of position. When disruption builds through the day, later services can be affected even after the original technical or operational problem has been contained.

The CAA has previously issued similar guidance after major events affecting air traffic control systems and airport infrastructure, making clear that passengers have strong rights to care and alternative transport, but that fixed-sum compensation under UK law will not always apply where the root cause lies outside an airline’s control.

How UK passenger rights work after severe delays

Passenger protections on most flights to, from and within the UK are set out in UK261, the post-Brexit version of the former EU261 regulation. According to the CAA’s official guidance on delays and cancellations, travellers have three broad types of right when a disruption occurs: the right to care, the right to choose between a refund or rerouting, and, in some circumstances, the right to financial compensation.

The right to care applies widely. The CAA states that if a flight covered by UK261 is significantly delayed, airlines must look after passengers at the airport by providing meals, refreshments, and, if needed, hotel accommodation and transfers proportionate to the length of the wait. This duty to care applies regardless of what caused the delay or cancellation.

In addition, if a delay stretches to at least five hours, or if a flight is cancelled, passengers can normally choose either a refund of the unused part of their ticket, or an alternative flight at the earliest opportunity. Where a flight was part of a return journey and the outbound leg is cancelled, CAA material notes that travellers can usually claim a refund for the entire booking if they no longer wish to travel.

The right to financial compensation is narrower. CAA financial compensation guidance explains that fixed payments are only due when a flight arrives more than three hours late or is cancelled at short notice and the disruption was not caused by circumstances considered extraordinary. The size of any payment depends on flight distance and delay at arrival, not on the ticket price.

When Monday’s delays count as extraordinary circumstances

Key to the CAA’s explanation after major incidents is the concept of extraordinary circumstances. UK passenger rights legislation exempts airlines from paying fixed-sum compensation for delays or cancellations where they can show that the primary cause was an event that could not have been avoided even if all reasonable measures had been taken.

CAA statements following previous air traffic and airport outages indicate that technical failures within national air traffic control systems, sudden runway or terminal closures for safety reasons, and certain airport-wide security incidents are generally treated as extraordinary. In those cases, passengers are still entitled to care, rerouting or refunds, but are unlikely to receive additional compensation under UK261.

Guidance published after past system outages has also explained that onward disruption directly caused by such an incident, including flights later in the day that operate with long delays or are cancelled because aircraft and crews are displaced, will typically fall under the same interpretation. This means that passengers on Monday whose delays stemmed entirely from these knock-on effects may find that airlines decline compensation while still being required to provide meals, accommodation and replacement flights.

The CAA’s consumer-facing information notes that this interpretation does not prevent passengers from challenging an airline’s decision. Travellers can pursue complaints through an alternative dispute resolution body or the courts if they believe that the disruption was within the airline’s control, for example where staffing or maintenance planning rather than air traffic restrictions were the real cause.

What help passengers should receive at the airport

Even when Monday’s delays are classed as extraordinary, airlines still have clear obligations. The CAA’s delays guidance explains that once a flight reaches specific thresholds of delay, airlines must provide care at the airport, increasing as the wait grows longer.

For short-haul flights, the right to care usually starts after a delay of two hours or more; for longer flights within the UK and Europe, the threshold is generally around three hours, and for long-haul services it is around four hours. From that point, passengers should be offered vouchers or other means to obtain meals and drinks, and given access to communication such as phone calls or emails.

If the delay stretches overnight or the new departure time is the following day, the CAA’s consumer leaflets state that airlines are responsible for arranging hotel accommodation and transport between the airport and the hotel. Travellers who arrange their own rooms because assistance is not forthcoming are advised in CAA material to keep receipts, as reasonable costs can later be claimed back from the airline.

In severe disruption of the kind seen on Monday, the CAA’s previous advice following major incidents at Heathrow and other airports emphasised that care obligations continue for as long as passengers are waiting for the alternative flight offered by their airline, no matter how long the delay lasts or what originally caused it.

How to check if you can claim compensation

To work out whether they can seek compensation after Monday’s delays, passengers first need to confirm that their flight is covered by UK261. According to the CAA, this includes any flight departing from a UK airport on any airline, and flights arriving into the UK on a UK or EU carrier.

If the route is covered, the next step is to look at arrival time at the destination. Public CAA guidance on financial compensation states that for delay claims, the important measure is whether the traveller reached the final destination more than three hours later than scheduled. For cancellations, it matters whether the replacement flight arrived more than two hours late and how much notice was given of the change.

Passengers then need to consider the cause. If airline communications and subsequent explanations indicate that Monday’s delay was mainly due to an airport or air traffic control outage, the airline is likely to argue that extraordinary circumstances apply and decline compensation while still offering care and rerouting. If, however, the disruption appears linked to factors within the airline’s control, such as crew resourcing or technical issues with a specific aircraft that are not linked to official safety directives, some travellers may decide to submit a claim.

The CAA’s published advice encourages passengers whose claims are rejected to ask airlines for a clear explanation of the reason given and, if still dissatisfied, to escalate complaints to an approved alternative dispute resolution scheme or the regulator, or ultimately to pursue the matter in the small claims court. For those affected by Monday’s events, that process may determine whether any financial redress is available beyond the care and refunds already provided.
