I am an occasional visitor to London with Virgin (off peak fares)from Preston , Lancs ,and I hold a senior railcard. I usually purchase an off peak zones 1-6 day travelcard capped for me at £7.80 . I have started using my contactless bank card when I estimate my journeys will be less than £7.80 in total. Am I right to assume that should my single off peak journeys within Z1-6 come to more than £7.80 ,then that is all I pay per day ? I have registered my bankcard with the tfl online page so they know I am a senior railcard holder!
