For each game one team is the home team, and the other team is the away team. The team playing in its own city is the home team. The away team is the opposing team that is from a different city. The Super Bowl is played in a neutral city that is determined before the season starts.
Several games a year are played without real home or away teams. The Super Bowl is always played on a neutral site, and the home/away designation switches between conferences each year. The Pro Bowl is also played on a neutral site each year, primarily in Hawaii. The NFL also travels abroad once a year for the International Series. Since the 2007 season, this game has taken place at Wembley Stadium in England. For this game the team that agrees to give up a home game and be the designated home team in England receives financial incentives.
