London in a week: a practical guide for New Yorkers
Farehaven advisors · September 15, 2026
Before you fly: the UK ETA
US citizens now need an Electronic Travel Authorisation (ETA) to visit the UK, even for a short trip. Apply on the official UK ETA app or GOV.UK, not on look-alike sites that charge extra; it costs £16 at the time of writing and most decisions arrive within three working days. Your airline will check it at check-in.
From Heathrow into town
- Elizabeth line: the best value for most people. Direct to Paddington, Bond Street, Tottenham Court Road, Farringdon and Liverpool Street; about 30–40 minutes to central London. Tap in with a contactless card or phone.
- Heathrow Express: 15 minutes nonstop to Paddington, pricier unless booked ahead.
- Piccadilly line: the cheapest and slowest, but direct to Knightsbridge, South Kensington, Covent Garden and King's Cross.
- Taxi: a black cab to the West End is usually £80–£110 depending on traffic.
Where to stay on a first trip
Covent Garden, Soho and Fitzrovia put you within walking distance of theaters and restaurants. South Bank and Bankside are great for walking the river. Mayfair and St James's are quieter and grander. King's Cross is excellent value with the Eurostar on the doorstep. See our London hotels for places our advisors book.
Day one after the red-eye
Overnight flights land between 6 and 10 am. Ask for early check-in (we request it on every hotel we book), get outside in daylight, keep the afternoon light (the Tate Modern, a walk along the river) and go to bed after 9 pm local time. Coming home, day flights from Heathrow land in New York in the afternoon or evening of the same day.
Money and phones
Contactless works almost everywhere, including buses and the Tube, with daily fare caps. Tipping is lighter than in New York: 10–12.5% in restaurants, often already added as a service charge. Check your phone plan; many US plans now include UK roaming.
