So it's basically 2 hours long, and in the evening rather than midday. I imagine it will help - especially a lot of leisure travellers - not a massive announcement I was hoping for though "We're changing Happy Hour to 4-6pm AEST Monday to Friday. It's now twice as long, double the happy! For today only, we're giving you a sneak peak of the fares that will be available between 4-6pm AEST. To book, visit virginblue.com.au during our new 2-hour Happy Hour and double your happiness today."
