Portsmouth sits around 67 miles south of Heathrow, and the route down runs primarily via the A3, typically taking 75 to 90 minutes depending on traffic through Guildford and around the Hindhead tunnel. It's a route we know well because a good share of these bookings are cruise passengers connecting straight from a long-haul flight to a ship departing from the Portsmouth International Port.
If you're catching a cruise, we track your flight the same way we would for any transfer, and can drop directly at the terminal rather than a general city-centre address. For naval and military personnel connecting through Heathrow to Portsmouth's naval base, the same fixed-fare approach applies — no surprises if your flight's delayed or the A3 is slow.
