So normally as a Floridian I drive to all ports. However we got the Alaskan cruise offer and booked. I booked back in September but couldn't do my flights on Southwest until January. I purchased transportation thru carnival from Sea tac to pier and back before my flights were bought. We gave them all of our flight info last week.We have an 11:40 am flight the day of debarkation. Hubby read the fine print and it said flights need to be 12 pm or later, I didn't see that when I booked but it's there ...now I'm wondering if that 20 minutes really is going to be a big deal and if I'm going to be in trouble..advice guys?
