We are flying SW for the first time next Friday out of BWI. We have purchased EB check in. How does the express bag drop kiosk work? Do we still have to check in in person, or can I just go to the express bag drop and go from there? Or, would it just be easier at BWI to use curbside and avoid everything inside? Also, once SW checks us in automatically, we don't have to go to the ticket desk do we? Thanks for any help, it's our first time on SW and just want to make sure we get it right. We are flying out at 730 am if that makes any difference.
