To be honest, what appears on a ticket 11mths from now on a route that very likely won't be operated by bmi, Regional or any combination thereof is not very important in the greater scheme of things.
If BA are no longer talking to 'Granite' as is suggested above, then that is worrying - unless there is another game in town.
If not, then what is the point of BA, having said Regional doesn't feature in its plans, not selling it to someone that puts in a reasonable offer to take it off its hands? What has BA got to lose? If Granite has the funding which supposedly it now has with a new investor, then BA should gladly sell & let's see if the Granite team can run & develop Regional...it's not exactly as if BA & Regional would be in direct competition?
Airline politics...don'tcha just love it!
