CX only has recently installed their new sleeper seats on 2 of their aircraft (17 more to go) but these are only deployed on the London routes.

The óld´seats are still extremely comfortable but one travels on CX for the service, food and reliability. I´ve had the experience on travelling on the óld´seats to London once and I was extremely impressed - they are better than BA´s flat beds too !

You have to note however, that CX only offers First Class on their lonh haul fleet - meaning 747-400 and A340-300 aircraft. All other aircraft only have Business Class seatings.

Still, they have excellent service.

Asiana on the other had DO offer their fully flat beds between US and Seoul. (They also have a much better safety record than the other Korean airliner).
