Heathrow–Amsterdam, Manchester–Dublin: The most stressful flight routes in Europe

Two UK air routes rank among Europe’s three most stressful flight routes for nervous flyers, according to a new AirAdvisor analysis of delays, cancellations, weather exposure and journey times.

London Heathrow to Amsterdam ranks second in AirAdvisor’s 2026 Nervous Flyer Index, while Manchester to Dublin takes third place.

The study examined 26 major European routes using operational data covering September 2025 through August 2026. It considered delays of more than one hour, severe delays exceeding three hours, cancellations, weather exposure at both airports, and flight duration.

Despite its name, the ranking doesn’t evaluate other factors that might make flyers nervous, such as the likelihood of turbulence, and it doesn’t imply these routes are less safe. Instead, it quantifies factors that can make flying more stressful and unpredictable for passengers who are already anxious about air travel.

Heathrow–Amsterdam has the highest cancellation rate

Heathrow–Amsterdam received a Nervous Flyer Score of 63.8 out of 100, making it the second-highest-scoring route in the study.

Its biggest problem was a high cancellation rate.

AirAdvisor found that 3.69% of flights were cancelled, the highest cancellation rate among the routes analysed and more than 2.5 times the 1.35% average among the top 20 routes.

• 3.63% of flights were delayed by more than one hour
• 0.37% were delayed by more than three hours.

Both Heathrow and Amsterdam had weather-exposure ratings of seven out of 10.

Once passengers manage to get in the air, the journey between these hubs is relatively short, with a flight duration of 80 minutes.

Manchester–Dublin has the highest long-delay rates

Manchester–Dublin followed closely behind with a score of 63.4, but had the highest delay figures in the study.

• 7.51% of flights were delayed by more than 60 minutes, the highest proportion among the top 20 routes.
• Manchester–Dublin also recorded the highest proportion of flights delayed by more than three hours, at 0.84%.

That means the route had the highest rate of long delays among the top 20 routes, but its cancellation rate was lower than Heathrow–Amsterdam at 0.81%.

Manchester and Dublin both received weather scores of seven out of 10. The flight duration is just 60 minutes.

Heathrow appears four times near the top

UK airports feature prominently throughout the ranking, with four Heathrow routes making the top 20.

• Heathrow–Frankfurt ranks eighth with a score of 44.2.
• Madrid–Heathrow is tenth at 40.8
• Heathrow–Dublin ranks 11th with the same 40.8

That puts five routes involving UK airports among the study’s 11 highest-scoring routes, four of them involving Heathrow.

Amsterdam–Barcelona tops Europe’s ranking

The highest overall Nervous Flyer Score went to Amsterdam–Barcelona, at 75.1.

Unlike Heathrow–Amsterdam and Manchester–Dublin, this route did not have the highest result in any disruption category. Its high score comes from a combination of high delay and cancellation rates.

AirAdvisor recorded hour-plus delays on 7.02% of flights, delays exceeding three hours on 0.83%, and cancellations on 2.93%. The flight is 130 minutes.

What does the Nervous Flyer Score actually measure?

AirAdvisor developed the ranking based on factors that can add uncertainty and stress to a journey.

“The purpose of this ranking isn’t to tell nervous passengers which routes to avoid. It’s to show where some of the factors that create uncertainty are more common, so travellers can plan for them and feel better prepared,” AirAdvisor CEO Anton Radchenko said.

Cancellations account for 25% of the score, delays exceeding three hours for 20% and delays exceeding one hour for 15%. Weather exposure at the departure and destination airports contributes another 15% each, while flight duration accounts for the remaining 10%.

Travellers can plan for these problematic routes to ease their nerves by booking earlier flights that are less likely to experience a cascade of delays. They should also familiarise themselves with their rights in case of delays or cancellations.

It’s also important to note that while cancellations and delays might make a journey more stressful, they do not make the flight less safe.
