The analysis, compiled by passenger rights specialists AirHelp, found that Portugal recorded the highest average delays among European countries, reflecting continued pressure on the aviation sector during the busy travel season.

While delays affected airports across Europe, Portugal’s heavy reliance on tourism and seasonal air traffic contributed to particularly significant disruption, especially at the country’s busiest airports.

Tourism and growing demand

Portugal welcomed record numbers of international visitors in recent years, placing increasing pressure on airport infrastructure and airlines, particularly during the spring and summer months.

Lisbon, Porto and Faro all experience substantial increases in passenger numbers during peak holiday periods, while air traffic control restrictions, adverse weather and aircraft rotation delays elsewhere in Europe can quickly affect flights operating to and from Portugal.

Although many delays originate outside Portugal, the interconnected nature of European aviation means disruption in one country can have knock-on effects across the continent.

Millions of hours lost

The report shows that European passengers collectively spent more than seven million hours waiting because of delayed flights during the first six months of the year.

AirHelp said the figures underline the continuing operational challenges facing airlines despite the industry’s recovery from the pandemic, with staffing shortages, congestion in European airspace and increased demand all contributing to delays.

Know your passenger rights

Travellers affected by lengthy delays may be entitled to compensation under UK and EU passenger rights regulations, depending on the cause of the disruption and the airline operating the flight.

Under EU Regulation EC261, passengers may qualify for compensation of up to €600 if their flight arrives more than three hours late and the delay was within the airline’s control. Extraordinary circumstances, such as severe weather, airport closures or certain air traffic control restrictions, are generally exempt.

Passengers are advised to retain boarding passes, booking confirmations and receipts for any additional expenses incurred while travelling, as these may be needed if making a claim.

Summer travel expected to remain busy

With millions of holiday makers continuing to travel throughout the summer, aviation experts expect airports to remain under pressure during peak periods.

Travellers are encouraged to check flight status before leaving for the airport, allow extra time for check-in and security, and monitor airline notifications in the event of schedule changes.
