We booked our Aug 1-13th flight with United in Feb. I check my reservations every once in a while, just to make sure nothing has changed. Good thing I checked this AM!! United has merged with another airline and they totally changed my flights. We were leaving DesMoines at 6:00 AM, arriving in Chicago 7:30 Leaving Chicago at 9:00 into MCO at 12:30...... United changed my flight to leaving DM at 6:00 AM Leaving chicago at 6:10 AM I was on hold with United for 55 minutes and they finally changed my flights. I had upgraded to "economy plus" at the time of originally booking....well the new plane from DM to Chicago is so small they, do not even offer economy plus seats. I am having to request a refund on-line. Has anyone ever been refunded from United and how long does it take? Check your flights and hopefully you won't be affected to much!
