I took seat 15A in anticipation of window seat, there is no window.

I took seat 15A in anticipation of window seat, there is no window.

The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

The cabin temperature was nice and cool. The wifi was not working.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

As previously noted, this flight was great: departure was timely, the crew was friendly and attentive, and wifi connectivity was seamless. In particular, I appreciated that the flight attendant just told me to stow the laptop right before takeoff/landing, and trusted me to do so (which I did!).

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

Entertainment is ok! Boarding and seat with zone is terrible. I paid for the seats but you didn’t give me what I paid for which is exit isles.

Flights were on time. Free Wifi on plane. Everything was well organized.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

No seat back entertainment. And app had a hard time getting entertainment loaded.

ticket agent lady wás very helpful , she arranged wheel chair for my elderly mother

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

The flight attendant in business class was excellent! Professional, friendly and attentive.

Delays with no explanation. It could have been handled better.

Ceiling fell down and had to have maintenance come and duct tape it up. No WiFi on the flight.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The flight attendant was friendly and efficient. The temperature was kept nice and cool. The plane was nice, but filthy. There were visible spills on my tray table. The gate agent was somewhat rude with her announcements and in speaking with other customers.

I appreciate that I finally got the seat I paid extra for this time. Thank you

I would have liked a pillow. The vegetarian wrap and oaten cake was good.

I would have liked vegetarian and gluten free options for evening dinner time flight. I would have like a pillow on the international overnight flight . The veg wrap and oaten desert on the international flight was good

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

They canceled both the flight to Myrtle beach and the return flight. They are an awful airline and they ruined my trip. I will never book with Spirit again.

The flight was a big joke very uncomfortable I had a horrible experience and I will never fly with them again everything about the flight was bogus and I’m not happy with it at all this experience makes me not want to fly ever again

Pricing, boarding time communication, over priced baggage and overall service is lacking, seating unconfortable

Flight attendant was all so sweet and pilot got us to our destination safely and on time

They cancelled our flight. 2 hours before we were supposed to take off and offered us nothing! We got our money back and that was it. No other flight to get to our cruise no working with another airline or with us to get there. Terrible customer service, no apology.

we boarded the plane and then sat for OVER AN HOUR on it, first waiting for fuel and then the crew timed out. the flight kept getting delayed longer and longer, a 9:30pm flight is still on the ground at 1:15am.

The airplane rattled near the left wing as if several screws were loose. Then after we landed in Fort Lauderdale, we had to sit and wait on the runway for quite some time. It was very scary and TOTALLY unacceptable!

Smooth flight staff very friendly and we arrived 15 mins earlier

I was in the airport when I'll check the status of my flight and it was canceled and without any reason. The worst of the worst ...

I never had an opportunity to experience them! They cancelled my flight TWICE!!!
