Story summary

Here's a summary of the news story:

Thousands of flights were cancelled and delayed at Heathrow, Gatwick, and other UK airports on Tuesday and Wednesday due to a technical issue with the National Air Traffic Services (NATS) system.

900 flights were delayed or cancelled at Heathrow and Gatwick on Saturday, causing chaos for travelers.
A similar issue occurred on Tuesday, when 1,300 flights were axed in total across UK airports, affecting tens of thousands of passengers.
NATS blamed a "flight processing system" failure, which was resolved on Wednesday, but the backlog of flights continued to cause delays and cancellations.
British Airways cancelled over 190 flights at Heathrow alone, while Gatwick saw 33 cancellations.
The issue has sparked calls for NATS CEO Martin Rolfe to resign, with Ryanair's chief operating officer Neal McMahon saying that "nothing has changed" since a similar incident in 2023.

The technical failure is believed to be related to climate change, which is expected to increase turbulence and disruptions in the air travel industry. The UK's air traffic control system is under scrutiny, with many passengers left stranded for hours or even days without compensation.

Why this leaning score

This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
