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.

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

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

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.

Cramped seating for me. Luckily it wasn’t a long flight

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

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.

Horrible. Flight was delayed for 4 hours first till 7pm. Then for one more hour. Then again and around 9pm we were finally boarded and waited for catering delivery for another hour. At 10pm we were not interested on food at all. Tired, sleepy we arrived after midnight. Insane.

I've never seen such poor lack of information at a gate station in 69 years. The flight from COS was to depart at 12:37pm. At boarding time, the gate agent in the microphone mumbled something completely unintelligible. I understood one word. "mechanical". Nothing else. Absolutely nothing else was reported for the next 1-1/2 hours. Past the time for departure, at 12:37pm, the gate agent simply walked away and the station was left unattended, as all of the passengers waited expectantly. The board still said that the flight was ON TIME. That was hard to believe since it was then well past 12:37pm and we all were sitting at the gate and there was absolutely no gate agent anywhere in site. I stopped an employee who was standing somewhere else and said that we can use some information. Much later, the same gate agent said that he will have information for us about 5 minutes but he "doesn't know any more than you do." Of course, five minutes came and went and he did absolutely nothing. One and a half hours after 12:37pm, he opened the door and began boarding. No explanation, no apology. Once we were boarded, the same happened on the plane. We sat. No explanation, no apology, from any flight attendants. Finally, finally, a pilot apologized and explained that there would be a delay. WELL NO KIDDING !

Our flight from Chicago to Des Moines was the problem flight due to a dismissive flight attendant. His conduct was unnecessary and unprofessional.. I will avoid using Americam Airlines again because of the situation. Very disappointing.

Mostly excellent. However, many too many gate changes. Connecting flight at ORD changed gate 6 times.

Mechanical issues and delays. I get it but bad experience. Turned my 3 hour airport experience into a 9 hours

The baggage process at the gate was terrible. Stay was not friendly at all

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

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.
