Re: No so great in time savings
IMSMR check in for Concorde was far more streamlined than that :-) That high ticket price included some nifty pre and after flight experiences.
I remember well the "BA" blue slippers & eye cover you got in your "personal" travel pack.
If someone is stumping up £7.5K+ for a ticket on a plane they would not want to be with the great unwashed in the same lounge as those heading out to *Ibiza*.
