How do air traffic control and crew problems differ?

The source of a disruption can affect carrier responsibility. Ask for the specific written reason and compare it with the applicable rule; neither label alone decides every refund, care or compensation claim.

What to check

Start with the airline’s notice, the original schedule, and when you actually reached your final destination. A departure delay and an arrival delay can lead to different answers.

What to do next

Ask the operating airline for its written reason. The rule checker can point you to the conditions worth reviewing.
