Good to know
Flying to London — your questions answered
- How much are flights to London?
- Round-trip fares to London (Heathrow, LHR) start from around $276 in the low season and average higher in summer. From the US East Coast, expect roughly $400–$600 return; from within Europe, nonstop fares can dip below $100.
- When is the cheapest time to fly to London?
- February and November are typically the cheapest months to fly to London, while July and the summer holidays are the most expensive. Booking one to three months ahead and flying midweek (Tuesday or Wednesday) usually secures the best fares.
- Which London airport should I fly into?
- London has six airports. Heathrow (LHR) is the largest and best connected to the centre via the Elizabeth line, Piccadilly line and Heathrow Express. Gatwick (LGW), Stansted (STN) and Luton (LTN) mostly serve budget and European airlines, while London City (LCY) is closest to the centre for short-haul business routes.
- How many days do you need in London?
- Three to four days covers the essential sights — the Tower of London, Westminster, the British Museum, a South Bank walk and a couple of neighbourhoods. Five days or more lets you add day trips like Windsor or Oxford and explore areas such as Greenwich, Notting Hill and Shoreditch at a relaxed pace.
- Is London expensive to visit?
- London is one of Europe's pricier capitals for hotels and dining, but it's easy to save: most of the world-class museums and galleries are free, an Oyster or contactless card caps daily Tube spending, and markets and pubs offer good-value meals. Budget travellers can manage on around $90–$120 a day excluding accommodation.
