As a season ticket holder you are one of First Great Western’s most important customers, apparently, and as a thank you for your continued custom, they would like to offer you a free First Class upgrade during off-peak journeys on your normal route for three months.
Go here and fill in the form to print off your upgrade voucher.
I know it's not much use to those who only use the train during commuter hours, but if you've been working late, why not take advantage of the comfy seats? I know I will be.
I don't want to sound an ungrateful note here, but do you know how I found out about this promotion? Not on the FGW website, not on a poster at the station (though apparently there are some, maybe I'm not paying enough attention), but on a FGW customer's forum. I sometimes get the feeling FGW have a tendency to bury their good news, why would they do that? Still, there it is, sign up today!
