Hi I'm trying to buy an annual season ticket for a colleague. They normally purchase Gidea Park to London, but I'm being given the option of a ticket with AAA Emerson Park for the same price. Am I right in thinking this means the ticket would give access to the Upminster c2c line into Fenchurch Street/Liverpool Street, as well as the NXEA line into Liverpool Street? Seems strange for the same price to give quite a few more options... Thanks!
