Now we know it:
Money and comfort are the key to long-term relationships.
When you buy a Travel Card season ticket for a longer period of time, the price per day is significantly lower. In addition to being cheaper, long-term relationships are easier to maintain: you don’t need to remember to top up your card every few weeks or months.
If you have so far used single tickets, remember that if you make three or more return journeys a week, buying a season ticket is more economical.
