TfL have announced that, for a trial period starting on 8th March, all Friday travel will be charged as off-peak. I am interested in travelling from Reading to Gatwick airport on a Friday in what would previously have been morning peak period. TfL's single fare finder quotes a fare for this journey of £21.10, compared to a normal peak time fare of £44 and a ticket price (from BRFares.com) of £54.80 for any permitted route, or £31.70 via Gomshall. If I travelled via Paddington and Farringdon (or Paddington and Victoria) and used contactless payment then it seems clear that the TfL fare would apply, but would that also be the case with the direct service via Gomshall, which goes outside the TfL fare area?
