Southwest today.... was in A boarding, middle of pack. A commuting FO was ahead of us by 15 slots or so and grabbed the good exit row seat. I only noticed because the group of SEVEN one person ahead of us took took the seat next to him.... and another 2 rows of all exit rows. But not all 7 of them boarded at once... just 1 and then later the other 6 joined. I felt bad for the pilot, he had to deal with some jerks next to him. My friend and I got a whole row to ourselves though.
