The London-to-Gatwick transfer heads south out of the capital, picking up the M23 for the final run down to the airport — around 28 miles in all, though the escape from central London is where the clock really ticks. It’s a longer haul than the Heathrow run, so leaving enough time is essential for a flight.
Gatwick’s split between North and South terminals makes it important to tell your taxi partner the right one, since being dropped at the wrong terminal means a shuttle ride with your bags. A pre-booked taxi is popular for early departures and family groups where the Gatwick Express timing doesn’t line up.
Allow around an hour to 90 minutes for the 28-mile trip, more at peak times. The slow part is usually getting clear of central London before the M23 opens up.
Gatwick has North and South terminals linked by a shuttle. Check your airline’s terminal and give it to the licensed taxi partner so you’re dropped at the right one.
Because central-London traffic is unpredictable, build in a generous buffer on top of the estimated journey time — especially for early-morning or peak departures.
