Top Gear did a race from Italy to the UK. Clarkson driving a Bugatti Veyron, Hammond and May flying in a Cessna 182. They couldn't fly over the mountains, and May wasn't qualified to fly at night. It didn't save a lot of time.
Not sure which bits you could cut with a flying car - the safety checks, air traffic control involvement, runways, refuelling stop, qualifications/licenses, but it would have to be a lot to make a large difference.
