Disembarkation has started around 7:30-7:45 for all of the 3 sailings we've been on out of PC. We just had a 12:25 or 12:35 return flight from our recent cruise. We didn't hang around on the ship too long because we saw how crazy long the security check line was the morning we sailed out. We got to the airport in plenty of time. It did take 35 minutes to clear security. We were down near our gate with time to get breakfast and relax for over an hour. Just make sure you don't hang around the ship a long time. Get moving early and go to Cabanas for breakfast or skip breakfast and get it once you clear security at the airport. You should be fine.
