No wifi, seems to be very common with Southwest currently. Everything else was normal.

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

Great job! My family doesnt fly often but we felt safe 100%

It was as expected and I was grateful for the wheel chair help and ease of use.

Great vacation. Can't wait till next year for another one.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

Tight seats. Be prepared to sit in the middle if you are in boarding group C.

This was a connecting flight for me and I had already traveled for 7 hours. First, the Pilot didn’t show up and then the gate changed twice, after which the flight was rescheduled for 2 hours later. This made me late and I had to make other transportation arrangements to get home to Astoria another 1 hour & 45 minutes away. This cost me $250 more than it should have. Will not fly southwest again.

It was good. I wish you had gluten free snacks for my husband.

Long layover in Chicago. Wish that could have been lessened.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

I am a die hard Delta flyer, but they missed it on this flight. It was on their very dated 717-200 aircraft, which I knew when I booked it so I knew it wouldn’t have seatback screens. However, the internet was awful and it wouldn’t even send texts a lot of the time, much less even connect to the delta app. It was also very hot while in the air, which never happens. What was even more disappointing is that the crew only gave me cheezits and a beverage, even though I was in Delta Comfort. The main cabin fare gets these items. I didn’t get any kind of improved snacks and that was unacceptable. The crew wasn’t very visible at all either. If this was my first delta flight, it would be my last. I am just going to assume it was a one-off flight.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

The crew on this leg continue to be extremely helpful with my wife’s mobility issues. They also came by many many times to ensure we were comfortable and had drink some food.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

I liked the cleanness in the bathroom and good crew on board and at boarding gates. There was no Hindi (Bollywood) movies. The entertainment can be improved as it is one of the worst one I saw when I compared it with other airlines. The Mumbai to Amsterdam flight did not have any food for my family which does not contain eggs in it though we have selected “Hindu Asian vegetarian meal”

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

they made me check my carryon. There was space in the overhead bins.

Cramped and uncomfortable seats. Not enough room for 6’2” person such as myself.

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

Everything went as planned. The only issue I had was with the gate C31 attendant. The person could barely speak English and was very difficult to understand.

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

Because of rescheduling, they had to put me on a flight that didn't go through Dallas

Packed commercial flight was as comfortable as can be expected

We were re routed due to a flight cancellation. We did not fly out of Miami. We originally booked first class and were moved to coach without being compensated.

2 gate changes, several announced delays, not enough room and seats at the gate. Many had to stand while waiting. The actual flight was fine.

American Airlines customer service was extremely poor. They canceled our flights multiple times. Then put us on standby trying to get on flights instead of booking us on a confirmed flight to get us home. So flight after flight we kept our hopes up just to be disappointed and stuck from a connecting flight. We had never been to Dallas so we were sleeping on the floor at the airport waiting to get home.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

The worst flight of my life. Never will I fly frontier again

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.

Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!

My departure gate was E10 but no kiosk at E10 for check in & no one to ask. A United attendant helped direct us to E38 for check in. The kiosks at E38 were all malfunctioning. A counter agent had to check us in. We then had to walk back to E10 for boarding. E10 to E38 at DfW is not an easy trek. No where in all the info they sent us indicated there were issues to over come. They can cut only so many corners. Luckily we arrived plenty early to deal with Frontier’s inefficiency.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.
