River...you ever been on a flight that landed in a thunderstorm? Would you rather have them divert? And since you don't fly SWA very often, consider this, if the flight got into MSY
around 11:00 a.m., Southwest has flights to Houston at 11:20, 12:45, 1:20, 2:10, 2:50, 4:00, 4:35, 5:10, 6:25, 7:10, 8:10, 9:10, and 10:15. In other words, they most likely were able to accomodate the HOU
passengers more quickly out of MSY
, and still get the aircraft to JAN pretty much on schedule.
