Was due to fly BA0218 today from Denver to Heathrow. Checked in last night with no problems. Woke up this morning to family telling me the flight had been cancelled so logged on to MMB - which said the flight was confirmed and operational. Then checked flight information separately and flight shows as cancelled. Can't get through to anyone at BA by phone to check which is correct. I don't want to rebook if the flight is actually going ahead.

Any advice?
