Reviews of the top 3 airlines serving from Chattanooga to Illinois
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
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.
Cramped seating for me. Luckily it wasn’t a long flight
5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.
Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed
Comfortable seats and good crew. There should be some breakfast options in menu for economy class to purchase Wifi was not working in the flight
On time. Accommodated carry on and personal bag in the plane. Good entertainment available and access without using own device. Gave a whole can of juice rather than a pour. Seat did not recline much.
Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.
The price. Omg $1100. Was crazy and it was not clear on the website.
Excellent. I had a medical emergency on flight SNA-ORD and the attendants were very helpful.
Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour
The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain
Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.
Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍
It would be helpful to be able to download an eticket from either American airlines or Cathay Pacific; not just Cathay Pacific.
The baggage process at the gate was terrible. Stay was not friendly at all
Not one thing to like. Three flights all with “mechanical” delays. Never got to where I was going and spent additional $500 for a hotel room. American Airlines is the worst in the industry!
It was canceled at the last minute. While I was literally at the airport. Messed my entire trip up.
The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?
Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.
Not sure the logic of the boarding in Groups. I was loaded first on the aisle. Then the guy in the middle. Then the guy by the window. Constantly holding up the other people boarding behind them with us blocking the aisle and this happened in most of the other rows
Delayed due to no crew. On a major holiday travel day.
Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.
Pulled out of the gate only to sit in the tarmac for an hour and a half for paperwork. Paperwork. Went back to the gate to refuel.
