Ask Customer Care and see what you'll get for arriving 33 minutes later than scheduled to FLL. Keep us posted.
I probably wouldn't get too chafed in my briefs over what ends up being a 30ish minute delay on the day AS did the cutover for eliminating the last traces of VX as a separate airline from the face of the earth (April 25th was that day), but you do you.
Things happen at airports. SEA's worse than it was even just a couple of years ago because DL's ramped up flights even more (in percentage terms) than AS has. More flights, same size airport = easier to get knocked off of schedule due to ATC holds (it's not like they can whip up another runway or taxiway if there are too many planes running around). The operations at SEA went pretty smoothly overall (you're the first thread complaining, and I checked delays yesterday, they were pretty "(excrement happens)" routine instead of the meltdown that happened when UA took over CO in 2012).
