Yesterday I made some journeys to and from Gatwick to check out various questions. I’ve updated the post above, but here are the main points:
- Auto topup won’t work if you have between £10 and the entry threshold at either Gatwick Airport or the Express gateline (p13/14) at Victoria. The gate will refuse entry citing insufficient funds.
- The entry threshold at Gatwick takes no account of whether you have reached (or might reach) the daily cap for Gatwick. You still need the full single fare to enter even if you won’t be charged anything for the journey.
- Between 1600-1900 you need the peak single non-express fare to London even though if you go to London zone 1 you’ll be charged the off-peak fare.
- If you do use the gates to p13/14 and travel on a Southern train you will be charged the correct fare to any station other than Gatwick, but there is no OSI so any tube or Southeastern journey will not get linked and you may be overcharged.
