Seattle - On Board Airline Checkin - Southwest Airlines

We have a late post cruise flight out of Seattle at 6PM. We are on Princess. We would like to do some sight seeing without our bags.

Does Princess and Southwest Airlines participate in the On Board Airline Check-in listed on the Port of Seattle website. Unfortunately there is little information on the website.

Check with Princess, we are taking RC out of Seattle, and I know Southwest was on their list as participating in the on board airline check in.

Princess says Southwest only participates in Fort Lauderdale.

You could pay extra and have checkin automatically done thru Southwest. It costs $12.50per ticket.
