Airbus A321 (N902AA)

Upgauges are always cool to see, and the huge travel weekend after Thanksgiving provides the opportunity to see many of them! In the airline industry we use the term "upgauge" for a larger aircraft being used on a flight instead of "upgrade" because unlike when a traveler gets upgraded from say economy to premium economy, which is a true upgrade, an upgauge is a larger aircraft being used on a flight. For most passengers this isn't viewed as better or worse just bigger. The same concept works in reverse in the airline industry with down-gauges as well. This particular flight was an upgauge from an Airbus A320 to an Airbus A321S. A side note is the aircraft flying this upgauge was N902AA, one of the first American A321S.
