That’s amazing, I never knew that option existed!
Two quick follow up questions:
– it is only available on LU machines from boundary to certain stations – i.e. is it just Lizzie Line, or also places like Gatwick, and up and down Thameslink
– is it available in reverse? Can you buy from Gatwick to Z2 boundary with or without railcard from a Gatwick machine, or do you need to do that awkward “buy a ticket to Clapham Junction because that’s the only station you can think of in Zone 2” thing?
