So i'll be flying into LAS from SJC on a Saturday, I am scheduled to arrived on a Delta flight (arriving at T1) and going onto a Virgin flight leaving from T3 going to LGW. Delta flight is scheduled to arrive at 14.10 and the VS flight to leave at 15.50. Is that enough time...?

The delta itinerary and VS are two separate bookings, so I think I know the answer... but can I check in my baggage at SJC right through to LGW?
