I’m flying to Chicago from DFW today on United Airlines first class.

My original flight was supposed to leave at 5:45pm and got delayed 3 times and it’s now at 10pm.

I was able to change my flight to an earlier flight (which was originally later than my original flight if it wasn’t delayed so much lol) on the United iPhone app.

I was wondering, how does this work for my checked luggage? Will it end up on my new flight? I’m tracking the bag tag on the iPhone app, and it already shows that it’s been updated to my new flight number.
