The aircraft scheduled to operate the LGW-JFK-LGW service is currently enroute from Dominican Republic to Gatwick and is operating to schedule with no significant delay. Just keep checking in the morning and the current ops delay should be absorbed. There's no significant weather related issues at Gatwick tomorrow. The only thing that could potentially affect things is there not being enough crew to operate the service. With so many services from JFK to LHR, the LGW service is usually the slack in the system when a flight needs to be canned but its highly unlikely that will happen.
