I have asked this question for Delta in an earlier thread - also for my DD (why does she fly more than me?! )....I have been trying to find a cheap flight for her home from DC on 7/17. I booked her outbound using miles(7/15) - but there wasn't any award availability for 7/17 at night or 7/18 in the morning to fly home. What I did find by searching other airports was a flight from DCA to MKE which has a stop/plane change in ORD for 7/18. This flight is priced $100 cheaper than flying from DCA to ORD only. So....my question is, can she get off the plane in ORD and not board the flight to MKE without any problems? Thank you!
