I would appreciate your advice and/or confirmation.

I was due to fly on BA-operated flights from Amsterdam to San Francisco via London (purchased as codeshare with American Airlines) on 5/28. My flight from AMS to LHR was cancelled due to the IT meltdown. Luckily, I was rebooked by AA from AMS to Dallas onward to SFO with a delayed arrival of 2 hours.

Per the information in 11.2 (Cancellation), I should be receiving 300 euro in compensation due to the +2hr late arrival at a destination that is >3500km (EU to non-EU). Did I understand it correctly?
