Both 737 and 320 in MIA. Both are “international” categories so can go pretty much anywhere AA flies. Bus category is smaller than 737 and a bit more senior. Both cover MIA, FLL, PBI. 737 trends toward 90/5/5 percentage trips out of those bases in order. Bus closer to 75/20/5. That’s very subject to change at a whim but seems to be the trend over past few years. 737 has more turns as a percentage of total flying than the bus, which locals like. Most of the turns are Caribbean, Mexico, Colombia, etc versus domestic. Bus has a TGU turn which is not popular and always in open time, MIA 737 also appears to have a higher number of turns as a percentage than western domiciles (LAX, PHX). Most 737 turns are out of MIA. PBI flying goes senior on both, but doesn’t appear to have a ton of turns... the handful that do exist go stupid senior.

Other than that, it’s got the same mix of 1-5 day trips as anywhere else. Commuters like commutable 4-5 days. Locals like easy turns and 2 days. Then a ton of people fall in between. Seniority is everything, surprise.
