Might interest London peeps. Improved Hopper fare Improved Hopper fare Unlimited bus and tram journeys in one hour for the price of one. Make a journey using pay as you go (contactless or Oyster) on a bus or tram, and you can now make unlimited bus and tram journeys for free within one hour of first touching in. Touch in using the same card on all the bus and tram journeys you make and the free fares will be applied automatically. Hopper fares apply to all pay as you go journeys. You can now travel on Tube, DLR, London Overground, TfL Rail, Emirates Air Line, River Bus or National Rail services between Hopper journeys, and Hopper fares will still apply. Hopper fares will not apply if your Oyster card has a negative pay as you go balance after the first journey. If you clear the negative balance within one hour of touching in, subsequent journeys made within the hour will still be free.
