An official announcement from the Detroit Red Wings has not yet been made, but a seating chart has been posted on the team's official website for the 2013 Winter Classic at Michigan Stadium. A seating chart has also been posted for Comerica Park, although it's not clear if the prices of the tickets on it are for the Great Lakes Invitational, the Red Wings-Maple Leafs alumni game or both.
The seating chart for Michigan Stadium (see below) shows a price range of $89-279 for tickets to the Winter Classic. The cheapest tickets are for the seats closest to the field since it'll be harder to view the action the farther you are down the bowl. The prices gradually go up to levels of $129, $149, $189, $219, $249 and $279. The most expensive tickets are in the luxury boxes on the east sideline.
For Comerica Park, the prices are much more affordable (see below). There are three price levels: $18, $28 and $38. The most expensive seats are in the upper deck, while the cheapest ones are in the outfield and around the first and third base lines and behind home plate.
Right now there isn't a specific date for when tickets will be made available to the public for the 2013 Winter Classic and other events.
