Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

On time arrivals and departure, good in flight entertainment, courteous flight attendants, decent meals, reasonable seat space

3hr delay and then missed connecting flight with another 6hr wait at the airport before getting a continuation to my trip, worst trip ever in my 50+years of flight travel

Without a doubt, my “customer service” experience with SWISS was the worst of my life. Multiple disconnections in conversations, very cold and indifferent staff, failure to follow up with promised status updates — simply put, T. H. E. W. O. R. S. T. A full week later, and I am STILL waiting to hear from them. Never again for me with SWISS. Disgraceful.

The flight and all amenities were good to excellent. SWISS was awful to deal with. Every step of the way they nickel and dime you. Chose your seats? $14. Change your seats… No accounting for the prior payment. You get billed again. 17 pound restriction on overhead luggage, nonsense. It’s a weight in the plane whether it’s in the overhead or in check baggage. They just milk you for every cent they can and I resent it. The flight was excellent.

plenty of legspace, snacks, no pull face from flight attendants when asking for a wine. Also fast transfer ability at ZRH.

The noise in the plane made the highest level of sound in the entertainment system ineffeective. The leg room was better than most flights bu the seats are not made for comfort. Food was ok but nothing to look forward too.

The flight itself was fine, but due to a snow delay my connection to Lisbon was delayed by six hours. Despite this, Swiss Air still managed to lose my luggage. Not acceptable. Someone else on the flight also lost their luggage.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

The trip was great until my luggage was lost on transfer from United to Swiss. It took Swiss 3 days to get my luggage to me though it was located almost immediately.

Horrible!! The WiFi was not working, the food was awful

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

On time, reasonably comfortable for economy, decent food. All in all a very good experience.

Every flight got canceled or delayed. Customer service was awful.

They lost my luggage and can’t find it. My trip is ruined. Online tracking of lost luggage doesn’t work

No free Wi-Fi. I have SkyMiles but not a high status, having an account has been enough for Wi-Fi on other flights, but this one was going to charge me to use it. Also turbulence was really bad toward the end, but I didn't count this in my ratings since I know Delta cannot control the weather - it's 2026 and lack of WiFi alone is enough for a poor rating.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Crew members were excellent. The seat wasn’t the best as well as a food options.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

They messed up my seat so I didn’t get the one I paid for

Put me on standby; flight was late; missed my connecting flight; disaster

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

In my first flight with Air Canada we sat in the plane for 4:00pm to 6:30pm. Finally we were asked to get off the plane and we were told the flight was cancelled after 7:00pm There was o clear explanation of what was the problem. I was booked without my permission on a Delta Flight at 7:30pm that was leaving at 8:00pm and I still had to go get my luggage(my final destination was Rome with one stop in Toronto. The luggage claim for Canada was closed so had to return to finally get it on the luggage belt.. Of course I missed the Delta flight and all the next day flights were booked. I also lost what I paid for my stay in Rome because I did nt cancel in time. A complete nightmare.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.
