Greyhound bus from Iowa City to Chicago – is it reliable?

Hey everyone, has anyone taken the late-night Greyhound from Iowa City to Chicago?

I’m looking at the one that leaves around 1:30 AM and gets to Chicago around 5:45 AM. I have a flight out of Chicago, but there’s only about a 3-hour window between arrival and boarding, so I’m a bit worried about delays.

Flights from CID are super expensive right now, so this seems like my only option—but I don’t want to risk missing my flight.

Has anyone taken this bus before?

Does it usually run on time?

Have you experienced delays?

Would really appreciate any insights!
