The entire crew were wonderful but 1 flight attendant stood out with his sense of humor on the microphone. I told him as much as I exited the plane.
8.0 ExcellentDanielle, Oct 2026
The entire crew were wonderful but 1 flight attendant stood out with his sense of humor on the microphone. I told him as much as I exited the plane.
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.
The flight was smooth. The Southwest experience has degraded overall, but this one was okay.
The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.
no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.
For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.
Great flight. I didn't get a drink because I was asleep whole on the flight.
Love them will get a Southwest card to track my points and keep flying with them. My family and I were pleased with the services.
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
It was as good as it could be. Flying is not a pleasant experience these days.
The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.
Smaller plane for a longer flight than my first one. Doesn’t make sense.
Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow
There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.
The whole experience was excellent. As it most often is with Delta
It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.
Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.
The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.
The first leg of my trip the Republic Airlines aircraft was late due to a maintenance problem. Then I called United to reroute. Their reroute airline lost my bag but found it and returned it two days later. Hopefully my return trip home is better.
There was not even a single time where united airlines from lga has made to the gate straight , 1 hr if delay today
Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.
Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.
I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A
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.
I had requested wheelchair assistance prior to flight. The airport staff had no record of it. It was not provided at Cedar Rapids which was a small airport, so I managed on my own. At O'Hare airport the same thing happened. The staff told me they had no record of my request for a wheel chair. But they finally provided it after a delay when I insisted that I needed it.
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.
first leg from san diego to chicago, only had cookies for snack. 1 flavor of sparkling water chicago to washington dc had option of cookies, pretzels, or gold fish. had 2 flavors of sparkling water. 2nd flight better however the best part was there was no delays!!! Got to chicago and washington dc early. That was wonderful!!!!
Business class flight attendant was very good. But our flight was delayed two hours for a “mechanical” bathroom issue that literally took 5 minutes to fix. Our plane landed early from its previous flight but still waited for a mechanic to show up to fix an obvious minor issue for almost three hours. This caused us to miss our connecting flight. They put us up in a Days Inn that was 17 miles away from the airport that took a half hour of driving just to get to and this was at 11pm at night. Then when we finally got back on a plane after a full day delay they left our luggage back in the airport. This was an international flight, so no luggage or belongings after flying 8 hours to a different country. We will NEVER fly American Airlines again.
12 hour wait in pdx to my initial flight to Dallas to hunstville
The flight from Chicago to Orlando was delayed inordinately. My whole journey from Lansing to MCO took 9.5 hours is just annoying and frustrating. We can understand the delays may be beyond their control, but overall the journey was so much waiting until reached to MCO. This is NOT the first time for me - but at least 80% of the time in this route. I barely remember reaching places on time.
Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.
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
The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.
