I was caught in the 27 May disruption, and I had connecting flights, I'm trying to work out how much compensation I should correctly receive. Here are my flight details:

27 May CAI-LHR BA0154, arrived on time but stuck on taxiway/gate for about 3 hours before deplaning (I don't know the exact timings, but flightaware shows on time but I remember being in passport control around 4pm).

27 May LHR-FRA, I should have connected directly to BA0912, however this was cancelled and I was rebooked onto 29 May LHR-FRA BA0904, so arriving just a bit less than 48 hours late.

Total flight distance is more than 3500 km, but the second flight is the connecting flight and is much shorter. 600 euro or 300 or 250 - ?
