Are there any Web Sites offering advice on how to calculate season ticket refunds or changeovers? This is so one can work it all out themselves before deciding what they might like to do next if anything. Sitting tight seems the best option now but I'd like to try calculating it all the same, How long would one need to be not travelling to make it worthwhile to change ones season ticket to a cheaper one and then change it back to a more expensive one afterwards? That is what I'm really interested in working out If you revert to a more expensive one, do they do it at the annual daily rate over 40 weeks or the day rate as if you held an odd period season ticket of between 1 month and 6 months? Clearly if one does this and then reverts back it is going to be at this years rate, so the time off would need to be long enough to make it worthwhile verse the increased price remaining on ones season ticket. I do appreciate one doesn't know how long they will be off and the closer one is to 40 weeks, the less the benefit. There again maybe the closer one is to the start of their season ticket year, the worse it is to change. However, a rough estimate of time would be interesting. Going for a cheaper season that doesn't cover me for travel to work might, of course, invalidate my travel to work loan I get. I have been using my annual season ticket for 5 months and 3 days, aka 155 days including today.
