What would happen (Option 1) if I didn’t have any checked luggage and didn’t take the last leg back to Chicago? Mark rene 1 year ago Reply @Mark – Likely nothing at all but know Delta, and all airlines, don’t like this. Also, in case or an IRROP, you may get routed to Chicago another way. Unlikely but could happen. Also you will get full credit for all the legs you fly but not the one you do not fly.
