This is a new wrinkle on flash tickets. I am guessing their Tier 1 games will not be available and those include games with Toronto, Montreal, Pittsburgh, Edmonton and Chicago.

Also fans will be able to buy concessions on their phone and just pick them up.

Their latest innovation will be dubbed the "Sabres Flex Pass" and will allow fans to access multiple games in a month by paying an $89 subscription fee. Tickets will be offered for 35 of the 40 home games, subject to availability, and can be requested 24 hours prior to the game. The subscriptions will go on sale Sept. 16 – the same day individual game tickets go on sale – and the Sabres are still determining how many they will offer.
Also fans will be able to buy concessions on their phone and just pick them up.
Fans who download the new version of the app will be able to access wait-time management, which will show lines at restrooms and concession stands near the fan's entered section number, and concession pickup ordering. The Sabres have partnered with concessionaire Delaware North to provide in-app ordering, which will start with three pickup points on the 100 level and one on the 300 level.
