How do I enter my passport information into an existing international itinerary?
 

I purchased a vacation package from Southwest Vacations. I have the confirmation # and can manage my reservation by logging into my account via Southwest.com, however, there is no option to enter my passport information.The only options available are:

Change Reservation
Cancel Reservation
Add Rapid Rewards Number
Add Secure Traveler Information - To add your Known Traveler/Redress number to an existing reservation
View Travel Funds

I'd like to check in at T-24 and feel like I won't be able to without entering passport information. I know I entered the information on previous flights.
HELP!!!

I'm sure it's on the SW webpage somewhere, but I've never found it. I just enter it all into the mobile app.

That worked! Thank you!
