If your on board a British Airways A/C or an Air Wales A/C then don't be alarmed then you will be on the correct flight.
I can only think of once the BHD - CDG service has been cancelled and that was mainly to a 3 hour slot at CWL.
*** Please be advised that the a/c stops in CWL en-route to CDG and is on the ground for 25 minutes. You will not have to disembark the a/c but don't be suprised if the A/C picks up a slot at CWL. ***
