A night flight on a Boeing 757-200 - 4 hours 40 minutes approximately - which was punctual this way, as well as the way out.

It showed that Britannia has the industry minimum seat pitch (28 inches) - I'm not very tall, and I found it incredibly uncomfortable - the poor legroom made me want to spread out width-ways, but I couldn't do that either, as the seats are too narrow.

In addition, they dim the cabin lights so you can sleep, and then put the video monitors on, making it more like a disco than a sleeping environment.

However - all that said, the aircraft was reasonably clean, the flight attendants were polite and helpful, and the pilot kept us well informed.
