My seat (9A) was very very comfortable. It was a convertible club Europe seat (these can be found in rows 1-17). It was very very wide, and reclined a lot. It is in front of a bulkhead yet it still reclines to the fullest degree. It had acres of legroom and felt very spacious. This plane was a widebody so there was a great feeling of spaciousness and it was not at all claustrophobic like some of the smaller planes. It is a shame they are phasing out these by the end of this year. They are being replaced with an Airbus a321.
The crew was top notch and answered all of my questions helpfully and were very cheerful throughout the flight.
If you going to book a flight to Athens, Larnaca , Istanbul or Stockholm this year try and book the 767 before it gets phased out!
