Some people ran into trouble with DFW airport's "Orange Wednesday" sale

People trying to take advantage of DFW Airport's "Orange Wednesday" sale ran into some trouble.

At midnight, the airport started selling prepaid parking passes for $6 a day. But, some reported the website kept freezing.

The airport reassured customers that its promotion was not sold out and they were looking into the issue. In the meantime, travelers can still use the DFW app.

The sale lasts until midnight Wednesday.
