When going to the kiosk this morning I noticed my flight this evening was delayed. At least that's what the computer said. So it gave me an option of free changes (up to 2 days later).
I had to go to the counter to let them know to change my checked bag as well. And the lady said it wasn't delayed.

Currently on UA's website it says it is delayed 28 minutes.

Isn't it funny how these things work? I do prefer an earlier flight though.
