Jeez you really don't want people criticising jet2 do you?! I fly for them and even I wouldn't defend them so vociferously. At the end of the day all airlines get complaints and in my opinion jet2 respond to them as well as most uk airlines. For the vast majority of the fare paying public though, unless they've had a really bad experience with a particular airline, will just go down the usual whichever is the cheapest on the days they want to fly route. And virtually none of them will have any interest in CAA statistics on complaints!
Anyway, the latest I've heard on the announcement which probably won't be an announcement announcement is that it might be in March, and PM has been spotted in Seattle, make of that what you will though.
