jorun I am not going to repeat your extensive post, but you essentially say that given C‑367/20 I do have a case to claim compensation under EU261 for a missed connection JFK-LHR (on Delta) - AMS (on KLM) at LHR due to late arrival of Delta? One ticket, Outside EU to an EU country, community carrier did part of the journey, so condition in 3 (1) fulfilled. Interesting and thanks for the extensive analysis.
