Tbe last couple of days seems to have descended into a squabble about who knew what when about when the 757's were leaving - guess what plans change. Being old enough to remember when the new 757 was being talked about as a derivative of the 727, they're just another of the ubiquitous twin jets...
I was told years ago by somebody in fleet planning for Britannia that selling the seats was the hard part. If they do, they'll always find somebody to operate the flights - doubt things have changed much.
