This might seem like a really dumb question, but I just booked an off peak return from Manchester to London Euston for tomorrow. Tried to get it from the National Rail website but it redirected me to Virgin Trains website... It was my understanding that an off peak return could be used on any off peak train, but on the Virgin site I had to start picking several times slots, so picked the one which was the most likely I would travel in (not really sure, just know I need to get there and back and spend 5-6 hours there). When I got the receipt it specified train times and said "Flexible ticket only valid at specific off-peak times of the day". I don't have a seat reservation as with an Advance etc, but the combination of the wording and the specific train times really confused me! I chatted to someone on the live web Virgin chat (if they were a real person) who said I could use any train tomorrow, so just wondered why they would have me picking time ranges and putting specific times on the receipt? Guess I am so used to using Advance tickets that I feel naked without my reservation and just want to double check I won't be getting someone telling me I have to buy another ticket tomorrow if I don't get on the train that the receipt lists.. Thanks!
