Taxi to LHR and then onto BA/AA to JFK ?
its poor but from the BA perspective it must be one of the easiest routes in the network to be forced to cancel and have the ability to shuttle passengers via heathrow to the correct end destination still.
Mot saying it’s good. It if you have a tech aircraft at Crowley international this route stands out as the obvious one to scrub and reaccomadate people
