What is the best way to get in and out of airports in London and PhnomPenh?

When getting to the airport for your flights from London to Phnom Penh, take into account the distance you would need to travel to each airport. Heathrow is the most central with the best transport options, but each airport has its transport lines. Taxi or rideshare is your most convenient option when travelling on a long-distance flight, but it is pricier. To Heathrow, catch the Heathrow Express at Paddington station to arrive at the airport in 15 minutes. Or, you can take the Piccadilly tube line direct to the airport and arrive in about 50 minutes. The cheapest option is to catch the bus at Victoria Station. To Gatwick, the express train or tube from Victoria station will take you there in the quickest time, but the coach will be the cheapest. Arriving at Phnom Penh, there are limited transport options, with the bus being the cheapest. You can catch the No 3 bus to the city, which runs daily. The most convenient and safest is hiring a taxi from the airport, but if you want to experience the local transport, a Cambodian tuk-tuk will be a fun way to enter the city. Which cities can you get to from Phnom Penh? Travelling in Cambodia is an adventure, and there are many cities to explore. If you want to dig deep into the history, then a journey to Krong Siem Reap is a must-see. Explore this resort town in northwest Cambodia and admire the carved stone buildings on the Cambodia flag. You can fly there on average in an hour or choose from a bus journey that will take about 6 hours. A shorter trip for a day outing is Krong Kampong Cham, which is, on average, a 2 hour ride. It’s a city on the Mekong River, famous for its French colonial buildings. Visit the famous Buddhist temple Banteay Prey Norkor and feel the ancient spiritual background. Stroll on the bamboo bridge and embrace the essence of the culture.
