 In contrast, fans of the North American sports leagues would need to travel by air if they wanted to attend most of their team's road games.Even if many thousands of fans suddenly had the means and inclination to do that on a regular basis, the North American commercial aviation industry at present would not have sufficient spare capacity to accommodate them – even events such as the Super Bowl which draw the most interest from fans willing to travel cause a major logistical challenge for airlines and airport authorities.As a result, unlike in most smaller and more densely populated countries, teams are typically not required to (and typically do not) set aside whole sections of their stadiums for opposing fans.
