My Saturday 07:25 departure on an E190 from Madrid had a grand total of 16 passengers on it. I passed out in 2D before we took off as I had not been to bed, and did not wake up until just before landing. A lovely plane but I think in this instance CE was wasted on me. Then again it was a £64 POUG. Is that early service into City always that empty?
On the way out I was on an Iberia A330-200 which was basically brand new, but that's for a different post!
