102 seats in a 321? Wow, US 321's are configured for 183 and parker is in the process of adding 4 or 5 more per plane now.
Little bit of historical trivia: The first jet transcons between JFK and LAX, flown by AA in early 1959, featured 707s with just 112 seats. The 102 seat 3-class A321s will debut almost 55 years later with 10 fewer total seats.
