We Just booked our tickets on Southwest - couldn't beat the price - almost $100 less than everyone else. We've never used Southwest before so I'm hoping someone can help. I know you can print the boarding passes 24 hours in advance, but I remember seeing different lines at their gates which determines who boards first. For myself it doesn't matter where i sit but my daughter needs a window - she's slightly claustrophobic and I need to make sure she gets a window seat. Any help would be greatly appreciated!!

Thanks! Michele
