This year I have flown Delta to Orlando 4 times, and will do so again (taking son, daughterinlaw, 8 yr old, and 1 year old) to OKW in October. We have had no problems with Delta Express. The only delay was one hour - it changed our flight from 7am to 8am. We are very pleased with the service. We used to fly USAir.....but I was tired of spending a day in transit instead at WDW.
