On August 25th the Giants are @ the Jets at Giants Stadium. Does this mean Giants fans sit on the visitor side of the stadium?

In the NFL there is no home and away side for fans... but since the Jets are technically the home team they would be on the side of the stadium with the press box.

yup you have it right.

It means that the Jets season ticket holders will get precedence over the Giants.

I think so. Is it just a pre season scrimmage, because they are in different divisions I think.

there arent really home and away sides, but the jets would be the home team, so they would sit, were ever the ticket says

Giants fans can sit on the Jets side if their ticket shows that they are sitting on the Jets or Giants side. So to answer that question, no.

The Jets will be the home team and Jets fans will receive preference to tickets.

It's pre season. What does it matter?

if the giants fans can get tickets
