Lets hope Iberia agree to the same - I originally filed with BA as i booked with them, and was on a BA flight number.. .they told me to refile with Iberia as the operating carrier...who knows if they'll agree to the claim
Im still out of pocket as we never made it to madrid and BA refused to reimburse the non-cancellable hotel in madrid so i now have to claim on travel insurance and lose out on the excess £50
