Flights from Greenville to Illinois: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Greenville to Illinois 
Verified travelerFlew with American Airlines-Apr 2026
Chicago has a enormous airport so be ready to walk and transfer to international flights by train via terminal
EllenFlew with United Airlines-May 2024
Greenville airport is small, getting through security won't take too long (particularly if you have Precheck). Be prepared to walk for 10-15 minutes from your arrival gate in O'Hare to your next departure gate, if you have one. Sometimes those gates are really close together, but my experience is that they are typically farther apart and require a solid walk.

Be on time. No issues with weather etc. entirely on airline.

Requested an aisle seat at the gate and got it. The staff so friendly

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

The delay update was very late. I had a stressful short connection and RAN through Chicago to get to the next flight, only to find the plane wasn't at the gate yet an nobody was boarding. I would not have had to run if the delay was updated earlier.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

Same the delay was not ideal and the credits to move flights was not sufficient

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

The crew were diligent about ensuring that our pet dog remained in his carrier for the entire flight, as is their mandate. I wish that mandate was changed so that our poor, scared pets can be comforted during a flight, whereas service animals get to stay out and about for the whole flight. Thank you.

Very good I can’t complain one bit. Thank you American Airlines for making my flight enjoyable and safe!

Everything was excellent and I enjoyed myself. Thank for everything

When my flight was delayed due to weather, I was rebooked to another flight since it showed that I would miss my connection. It was a lot of work to get back onto my originally connecting flight which was also delayed. That part caused a lot of stress and frustration. The ticketing agent at the desk was not very helpful.
