Reviews of the top 5 airlines serving from Buffalo to Illinois
Maybe different snack selection. To much sodium in them. I know refrigerators are not available but there has to be healthier items.

Wasn't expecting this, but, we actually ended up getting assigned to the first row of seats!!!!! The extra legroom came in handy
Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.
Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!
Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!
It went well. Plane wasn't full. Will be great when assigned seating is in place
My bag was damaged and is now missing a wheel. I tried to buy a claim in on the website but it would not accept my confirmation # for submission. Other than that, everything else was good!
As always it was a pleasure to fly on southwest.
Excellent! There was a delay due to the weather and they did all they could do to keep us comfortable & updated. Thank you!
Couldn't connect to the internet and movies. Needed help.
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 seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.
3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.
The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.
Their app did not recognize my Aeroplan frequent flyer number and would not allow me access to my boarding card. Ground staff was readily available at the airport to print it out to me.
The flight attendant was snarky and the flight took off very late. I know it was an issue with air traffic control and the runways in Boston, so not really anyone's fault, but very frustrating, I missed an important meeting because of rgr delay. They didn't offer headphones to watch the TV, but luckily I remembered my own and was able to enjoy watching a movie.
The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.
JFK is the worst airport and JetBlue is the worst airline
Very poor help no one answering a question regarding seating. Very rude staff. They don’t care, as if it’s not part of their job. Flight was delayed for no good reason and no apologies given.
Jet Blue cancelled my flight after I had boarded. They attempted to rebook me for a new flight two days later. I was able to rebook with a different airline, but not until the next morning. As such, I was forced to get an expensive hotel and missed important work meetings Monday morning. I am very disappointed with the customer service and will be pursuing full reimbursement for my hotel cost.
You did a great job rescheduling my cancelled flight. However, you made me pay for two seats for $118 even though the seats on the original flight were free. I think that was a very unfair thing to do.
A more comfortable seat. Padding would be really helpful but I've read the airlines don't want customers to be satisfied with economy seats.
Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.
I volunteered to let them put my carry on suitcase in the baggage storage area. But when we landed I was told it was being unloaded IN A DIFFERENT TERMINAL! I had to walk (painful for me) a long way to retrieve my bag and my ride had to move from the waiting area they were in to a totally different one. Not happy.
In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.
It was OK, but it was delayed about an hour, and my luggage didn't arrive till about an hour and a half after the flight
Another American Airlines flight, another significant delay. At least this one wasn't canceled like many others have been. This time we sat on the runway at LaGuardia for 2.5 hours. By my count that is 7 American flights the last three months that have been delayed 2 hours or more or canceled entirely.
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.
On time departure & early arrival. Made a long day much better.
The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.
Flight was delayed half hour before boarding, but when I checked flight aware the plane that would Pick us up had a delay of more than an hour. AA should let us know in advance to avoid waiting several hours in the airport
There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.
It was good experience this time. The flight was on time.
The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.
The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.
Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy
The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve
Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.
This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.
The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company
Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.
Severe turbulence. Captain never came on to reassure passengers after things settled down.
We were delayed three times ,and that destroyed my plans, and reservations
The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew
Be prepared for crowds and chaos upon arrival at the Orlando airport
