There are six airlines offering flights to London. The most direct route isn’t necessarily the cheapest – being flexible is key to finding the lowest airfare rates. For example, try searching by month to see the best time of the week to fly. The cheapest date is currently 07 / Feb / 2025.
London Heathrow is just one of the airports in London. If you're not set on a specific airport, try changing your search from London Heathrow to London to see a broader range of flights – they might be cheaper. It usually takes about 19 hrs 35 mins to fly 8043 km to London Heathrow.
During this peak season, hotel and holiday prices often increase too, so it's best to book early. Or you could keep your fingers crossed and hold out for a last-minute deal.
