Excuse me Jethro - this just in from the CC Thread ...
Where did you get your figures from. Here are the planned and cancelled flights between 0600 and 1200 today from LHR (excludes codeshares on IB, AY, etc):
Time Total Cancelled
0600-0700 3 1
0700-0800 22 9
0800-0900 19 2
0900-1000 24 8
1000-1100 16 4
1100-1200 22 8
Total planned flights 106, total cancellations 32. So, BA operated 74 flights or 70% of flights, which is better than the plan.
