Researched guidance, not a firsthand report, checked 8 November 2026 against the linked official sources.
Choose the route before the payment method
Start with your accommodation address, arrival airport and terminal. Those three details narrow the useful routes before you compare timetables. A good plan also names a fallback, because queues and delays can make the first choice unavailable. This guide covers the payment decision, the ticket rules worth knowing and a first day with a sensible radius. Treat it as a starting plan rather than a complete city guide.
Pay as you go, with one card or device
Contactless and Oyster support pay as you go on the services listed by Transport for London. Use the same physical card or device throughout the journey; on rail, touch in and out, while on buses and trams you only touch in. Some services and areas have exceptions, so check the exact airport journey instead of assuming every airport follows the same rules. The fare finder is the place to confirm how your route is charged. [1]
Visitor options include the Underground, buses, the DLR, the Overground and the Elizabeth line, and walking can suit shorter journeys. The official visitor guide links to maps and accessible transport information, which helps you choose by destination rather than by mode alone. A second mode nearby is useful insurance when your first choice is disrupted. [2]
Do not assume one cap covers everything
A single fare cap is not a promise that every mode, airport service or outlying area is included. Check the specific route you will use, and look separately at any part of the journey that falls outside standard pay as you go. The operator's route planner can show the rule that applies, and any leg with its own ticket should be bought separately rather than covered by assumption. [1]
Build the first day around one corridor
Pick a cluster of places that sit on one bus or train line, then add one nearby fallback in case a queue or the weather changes your plan. Walking between close stops can be more rewarding than another train ride, but the distances add up; save the long hop for a bus or train and keep your legs for the area you came to see. Leave the evening unbooked. One neighbourhood, one meal and one landmark is a realistic arrival-day target.
Sort the details before you land
Save your address, the station or stop name and a screenshot of the route. Make sure the phone you plan to tap is charged, and carry a backup payment method if you have one. If your flight is delayed, check live service information before choosing a route. Take the option with the fewest changes that you can handle with your luggage, then commit to it.
