Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

I'm glad it wasn't only 75% full because I could get a good seat

We waited in the airplane for over 45 min for a southwest employee to make the flight. This cause over half the plane to miss their connecting flight in Denver. When we confronted the desk upon arrival, they told us the only flight they had was the next day leaving at 8:50 pm!!! Or they offered to get us to Burbank or LA, but after that we were on our own to get back to Santa Barbara. I paid for a flight from sba to bna bna to sba. My re entry into mom mode has been 💯 rough because of southwest mistake with my flight. And now I’m leaving to Reno tomorrow for a vballl tournament and just discovered that my leg in Vegas has me and my 3 kids on a stand by flight even though I had booked these ticket last year November!! Do better southwest!

I flew twice this week on Southwest, was delayed over 2 hours both ways. From Pittsburgh to Chicago it was due to weather but the gate agents, pilot etc were great at updating everyone. Today from Midway to Pittsburgh the plane had come from an international location, kept getting delayed, no information was given until we were delayed for the third time. It was ridiculous, whoever scheduled that plane to fly to Pittsburgh after didn’t consider a lot of things.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

Worst experience I had on Southwest. Still better than most, but the seating was barely tolerable.

The crew was very nice and respectful and everything went well.

Having a direct flight between Pittsburgh and Austin makes traveling so easy.

The crew was excellent but the entertainment did not work. The 3mm jack for the headphones was faulty and no sound was available for entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

2+hrs delay without any reason provided and a cramped flight

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The employees at Sioux Falls airport were friendly and helpful. As a veteran/retired military Allegiant allows two checked bags, one carry on bag and a seat on the plane all at no cost. The flight crew and pilots were friendly and very competent.

The check-in and flight crew employees are excellent. The flight was good and the seats were adequate.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

No food is available without purchasing it and there is no in-flight entertainment. Both of these are OK because we got an inexpensive flight from Allegiant and, otherwise, our experience was excellent.

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

The flight attendance were very pleasant and funny. They made boarding and the flight very pleasant. Just wish the seats cushions had more comfort. Very flat and hard.

Flawless as usual. I understand on the smaller airplanes that WIFI is not available, and that is expected. The crew were awesome!

I sat in seat 22D near the back right of the plane. My phone battery was getting low, so I plugged my charger into the power outlets below the seats in front of me. They did not work. When I asked the flight attendant whether this was the case for the whole plane he said, "No. It's only this one. It hasn't worked for months". This should be noted to whomever services this plane so that maintenance can fix this for future passengers. I was on Flight AA5614 from Grand Rapids to Philadelphia on Wednesday, September 23, 2026.

I don’t think I’ve ever had a flight with American that has been without problems. Mostly delays - this time for over 3 hours. They should have just brought another plane into the terminal but they just had everyone sitting around misterable all day. They turned a 3 hour flight into a 12 hour trip for me (including the “planned” layover). It was ridiculous.

The flight was delayed but we were given no updates. The time just kept changing in the board. We were delayed on the runway as well. Then, my bag was lost and still hasn't been returned.

My flight depature was changed. Then it was delayed, and then cancelled after I reached the gate.I paid $231 for a hotel room that I didn't get to use because I arrived 24 hours later than I was suppossed to. My wife had to pick me up from the airport and I had to pay for an another ride back to the airport the next day. They did get me faster/ priority through TSA. The 2nd flight was okay

It was significantly delayed. Also the admirals club in Philadelphia airport near Gate B is absolutely filthy. Good was on the floor. Flies on the cheese. And the men’s restroom had pools of urine on the floor. I am not using that lounge again.

It was good overall. On my transition from Philadelphia to Boston,the gate information wasn't correct. When I went to check the gate information; I found out that my flight was boarding clear across the airport at another gate. Fortunately I rushed over there and made it on time while they were in the middle of boarding.

temp inside the plane was very hot and could not be adjusted.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

Not clean and was told I would get a great seat and it was not great at all

No knowledgeable staff at the counter or in a flight crew. No one knew why once flight landed at Philadelphia Airport then it took them 4 hours from runway to gate . Damn they took 4 hours to reach the gate . They messed up whole night for myself and for my kids.

Horrible communication about delay of flight and what options were available

Online check-in was not user-friendly. Too many fees, not cost effective.

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

I had a terrible experience with Frontier. I arrived before the 60 minute cut off and was told that Frontier has a two hour window for bags. I was then told the next available flight wasn’t until the end of the day (I had booked a 6am flight). I took a look around and saw other people being told that they could not board their flights or that they had to pay additional fees. I opted to rebook on American Airlines. There’s absolutely no straightforward way to contact Frontier, so this ticket was a complete waste of money. Oh - and the kicker is that the lady lied about the two hour cut off.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(

Everything costs something on this airline .... even snacks!! What a racket! We got to the airport nice and early only to wait in a line while there were no reps at the counter. Once we got to the counter to check our bags (which cost almost as much as the flight to check), we were told we were too early?!!! and had to wait an hour to check in. Then, to add insult to injury, because we didn't PAY to choose our seats, we were seated separately. I HATE THIS AIRLINE.
