The cheapest flight and the cheapest airport are not always the same thing. A bargain fare from Stansted can be eaten up by a longer transfer, while Heathrow's convenience sometimes justifies a few pounds more. Here is how to weigh airfare against the true cost of getting there from the Chilterns.
- The low-cost hubs, Luton and Stansted, usually have the cheapest headline fares for European routes.
- Heathrow offers the most routes and is closest to the Chilterns, often worth a small premium.
- Always add the transfer cost and journey time to the fare to find the genuinely cheapest option for you.
Which airports have the cheapest fares?
For European city breaks and holidays, the low-cost carriers based at Luton and Stansted typically post the lowest headline fares, easyJet, Ryanair, Wizz Air and Jet2 fly from there precisely on price. Heathrow and Gatwick carry more full-service and long-haul routes, which are not always dearer but rarely the rock-bottom option.
Cheap fare, but how far is the airport?
This is where a bargain can unravel. Stansted is 80–95 minutes from Gerrards Cross and Luton 40–55, versus Heathrow at just 15–30. A £20 saving on a Stansted fare can be outweighed by the longer, pricier transfer and the extra time. Always compare the total, not just the ticket. See our airport transfers guide.
How do you find the true cheapest option?
Add three things: the fare, the transfer cost both ways, and the value of your time. A cheaper fare from a distant airport may still win for a big saving; a small saving rarely justifies an extra two hours on the road. Run the comparison for your specific trip rather than assuming the budget airport is always cheapest.
Does the closest airport ever win on cost?
Often, yes. Because Heathrow is so close to the Chilterns, the shorter, cheaper transfer can offset a slightly higher fare, especially for a family or a short trip. Convenience has a value too, an early Heathrow flight beats a 4am Stansted slog for most people. See our cost comparison.
