Well they settled with me today. Deadline for CEDR after repeatedly telling me the 268 (2-6-late more like) was not 261 eligible.

I guess it’s easier to tell a full a380 that they are not eligible and hope that they go away.

“…firstly we'd like to apologise for the disruption to your flight home from Los Angeles. We don't underestimate the inconvenience caused. We appreciate you were initially advised that your claim for compensation in line with EC Regulation 261/2004 had been refused because the delay was “extraordinary circumstances”. We have re-assessed the details of this flight, and can confirm that EU compensation will now be paid for this delay. Please accept our apologies that this was not decided sooner. Should you wish to accept our offer, please select the option to accept on this portal and we'll process a bank transfer using the Starling bank details previously provided to us. Best regards, British Airways"
