BA look to have cancelled today's BA1311&1313 ABZ>LHR, and are now highlighting a delay on tomorrow's 1311(which I'm booked on). The seat maps also suddenly got a lot more restricted - yesterday there was lots of available space then this morning (before and after T-24) it suddenly became very restricted. Would this suggest BA are planning to pull the same trick tomorrow and cancel one of the planes going back and forth between LHR and ABZ and squeeze all the passengers on to the other plane? A cynic might suggest they are trying to use the fog as an excuse to reduce costs and squeeze everyone on to one plane.
