So I turned up at NCL without OLCI at 9.30 and proceeded straight to the check-in counter. The helpful lady was on the phone for 20 minutes and sorted me out with NCL-LHR-MAD-BCN. So I will hopefully get there in the end. Looking forward to my first flight on Iberia. We had the ex-BMI flat beds on the way down too - not bad, but certainly not as good as Club World. For a flight of that length I think row 1 of regular CE is actually slightly more comfortable.
