The old BOAC/BEA split looms again. The last time BA did a public change to the format of the company (something about Future Size and Shape) they specifically ruled out a return to long haul only.
I did not believe it then and I do not believe it now. When, eventually, all the short haul goes (to a mix of the LCCs and BDs etc.) they will say, "The market changed." Rather than, we mucked it up. Of course, the Brit govt forcing the merger over 30 years ago also mucked it up.
