This flight was scheduled to leave at at 8:50 PM and due to "maintenance" issues, the flight left after AM on May 24. Ultimately, the flight arrived at LHR at 2:20 PM on May 24, instead of scheduled time of 10:40 AM. I'm unsure exactly what time the plane's door was closed.

Announcements were sparse and the AA app wasn't very helpful. The departure time changed several times.

I understand UK is still part of the EU 261 rule.

I missed my train to York and was forced to take a later train, for which I wasn't charged extra,

What does AA owe me. I've seen where arrivals are more than 3 hours late, it could be several hundred dollars. Is this provided by voucher or cash? What response can I expect from AA> I have 75K (Emerald) with AK, not with AA.

My return flight was fine and uneventful. Any thoughts from FT?
