Thanks, I’ve had a long look through the main thread and it’s still confusing me, mostly due to the various components of the changes.

- additional layover (probably not relevant)
- greater than 1 hour earlier departure
- less than 3 hour arrival ‘delay’
- part downgrade on short layover leg (2500km)
- it was paid in avios / 241 companion voucher


one thing mentioned in email is that it’s operational cancellation which is a positive (for a case).

my assumption would be €600pp + refund of downgrade of an assumed avios cost of ORD->SFO (maybe at 50% due to companion voucher being used).

I’ve had multiple flights cancelled / delayed recently and decisions seem to vary, none being as complicated at this.
