I doubt that anyone is denying BA failed to deliver the service that was paid for, but it is legitimate to question the assumption that that automatically provides an entitlement to “compensation”. If my weekly grocery delivery arrives with the eggs and bread missing I suffer far more inconvenience than I would having to endure a 40 minute flight without a small salad, but no compensation would be due. Why does every BA service shortfall automatically have to lead to a credit to our bank or Avios accounts?
