VS01 LHR to EWR on 1st of July

Hi,

I'm tracking which plane was used on the route (as I'm flying later this month and hope for UC refit cabin). I'm using thevssource.com but it doesn't show anything for July 1st ... does anyone know which plane serviced this rout?

Thanks

Looks like there was no VS1 service on 1st July. Flightradar is showing no record of it either.

That is weird ... why would they not fly LHR-EWR on a Saturday ... and VS01 is the only flight for this route
