Por El Amor de Zih

We booked our direct fight r/t from Chicago flying down 1/2 and return 1/30 in Feb. It still shows the flight is still scheduled. I was just playing around today for Sept even though we were not booking. Was surprised the Sat to Sat was over $1000. I know the price changes from day to day. We are concerned when United starts their Houston flight to "Z" and their direct on Saturdays from Chicago.
