Although Gatwick and Heathrow are both London airports, they are 45 miles apart and there is no quick way to travel between them. If there is any way to avoid this journey, avoid it.If you need to pick up a connecting flight how long will you need to get from Heathrow to Gatwick? This is another common question.
BA suggests a minimum connecting time between a flight into Heathrow and one out of Gatwick of 3 hours, including a coach journey of between 1 and 1½ hours. But this must be for domestic flights
We don’t think that 3 hours is anywhere near long enough for international flights, where you would need to be at Heathrow a minimum of 2 hours before your next flight. We think the minimum should be 5 hours for an international flight, more if you are travelling during rush hour (see below). And this assumes that your flight into Heathrow lands on time.
Here are your options if you need to travel Heathrow to Gatwick:
Train: There are no direct trains from Heathrow to Gatwick. To do the journey by train you have to take the Heathrow Express from Heathrow to Paddington train station (15 minutes; £14 single), then transfer to the Underground and take a ‘tube’ to Victoria underground station (Circle Line, about 30 minutes; £2 single). Then it is another walk – from the Underground to Victoria train station – before you take the Gatwick Express to Gatwick south terminal train station (30 minutes; £11 single).
Including transfers, walking between the underground and train stations and waiting for trains, you can expect this journey to take around 2 hours and cost £27 per person.
Coach: National Express Coaches (National Express) run up to 100 buses a day between Heathrow and Gatwick. The fare is £17.50 for an adult and £8.75 for a child. The official journey time is 60 – 70 minutes, which is fine for most of the day.However, if you are travelling during rush hour on the M25 (any time near 07:00 – 10:00 or 16:00 – 19:00), or there is roadworks, an accident or any other hold-up, you can add 30 minutes or more to that average journey time. It will still be quicker than the train, and you don’t want to travel through London during rush hour.
Taxi: You could also take a black cab or organise a transfer via a taxi company advertising airport transfers. But they will take the same route as the coach (there is no quicker way or short cuts for this route that the coach won’t take too). So the journey time will be about the same as on the bus, but the fare would be from around £90 plus tip!If we were doing it, we’d allow plenty of time, buy a novel, and take the bus.
