My flight from Las-Dfw-Hel-Arn was diverted yesterday to ABQ and then cancelled and left me ABQ overnight with very long queues for rebooking. Due to DFW issues. Do I have right to EU261? Flying ABQ-LAX-HEL next day but delay is 24 hours. I cannot go to ARN anymore so they routed me directly to HEL. Does this affect for compensation? Ticket was Finnai but LAS-DFW leg operated by AA
