I know however they structure the tiers and dates etc we will always complain but having the "General Sale" as late as the 11th April is pretty harsh. My pal is trying to fly over from Australia... but can't confirm he has a ticket until 11th... that's pretty wild and most folk abroad will be in this situation trying to arrange travel & hotels last minute.
Ideally they would have done the sales 2-3 days apart rather than 1 week... it cuts things quite close to the wire.
The length of the windows makes no sense. After today we'll barely sell another ticket for a week. By which time hotels, coaches, train tickets become harder to book or more expensive.
