We upgraded to Economy Delight at Heathrow and we were lucky enough to not have anyone else on the row of three with us, so the flight from the get go was fab! The upgrade is definitely worth it on a long haul flight as there is so much more legroom. The plane itself was very clean and comfortable. The staff were friendly and welcoming. The food was good with a nice selection to choose from. And with constant refreshments during the flight, it made for a very good flight. I look forward to flying with them again!
