I have a friend coming to visit me the day before my birthday and the only flight that I could find that arrives in the morning into Milwaukee from LAX is on Delta..I don't have any experience with Delta flights..the price is good considering he's just over 2 weeks out only $89 plus luggage which i know is $23 for the first piece..what other costs do I need to tell him about? does he check in online 24 hrs ahead? he hasn't bought his ticket yet but will soon and i know those prices can change...just want to be prepared as to what he can expect..do they changed their schedules a lot? thanks for any info you can give...opps i posted this on the budge board, meant to put on transportation, mod can move if need be
