I have a trip booked with Southwest. I booked with points a few months ago, now the same trip is 7k points less. Is it worth it to cancel and reschedule it? Also when looking at the times on the flight is it always my time or is it local time? I cant figure out how long the flights actually are. It says I have a 8hr flight from Baltimore to Puerta Vallarta, leaving bwi at 6am and arriving at PV at 1pm
