On 8-8-2017, DL49 was delayed, causing me to miss my connection at JFK and arriving 6 hours late at final destination.
According to KLM, the delay was due to late arrival of the aircraft due to weather. Not true, the aircraft left the gate on time, but was on the runway for almost 1.5 hours, due to brakes needing to cool down. This information was given by the pilot.
What can I do to claim compensation?
