Yes, you can use an Oyster card (or a contactless payment method like a bank card or mobile device) to pay for travel on the Gatwick Express between London Victoria and Gatwick Airport in 2026. However, it is a high-value peer tip to know that while Oyster is accepted, the Gatwick Express is significantly more expensive than the regular Southern or Thameslink trains that run on the same tracks. In 2026, a one-way fare using Oyster on the Gatwick Express is roughly £22, whereas the Southern train might cost around £17–£19 for a journey that takes only 5–10 minutes longer. Note that you cannot use an Oyster card if your journey starts or ends outside the London "Pay as you go" zones, and you must ensure your card has sufficient balance for the high airport fare before you touch in. If you are a frequent traveler, the daily price cap for London zones 1–6 does not cover the Gatwick Express, meaning the airport fare will always be an additional cost on top of your standard daily travel spend.
