Or from the system full stop.
Costs didn't increase overnight, but on axing the T&W ticket, fares did.

Saying that, travelling prior to 2006, I never bought an adult day ticket, other than a GNE product.
Had Teen Traveltickets, but never bothered with the adult equivalents.
Since 2006, I have very rarely purchased a GNE product, other than singles and very rarely a red or red/green when going that way.
The Day Rover and weekly/monthly equivalents are no brainers as far as I am concerned. Offering fantastic flexibility throughout Tyne and Wear - not just a couple of zones.
If a bus is late, I can jump on a metro. If the metro is having issues, I jump on a bus.
I can get on any operator and have a day out at the weekend too - getting fish and chips at North Shields along the way, after jumping on the ferry.
