Super friendly crew, good communication. I wasn’t expecting food on a short flight but they handed out a cheese sandwich on pretzel bun, very nice!

Super friendly crew, good communication. I wasn’t expecting food on a short flight but they handed out a cheese sandwich on pretzel bun, very nice!

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.

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

One would expect far better service and quality of seats from Swiss. The crew was super cold at best. My wife and I are both Star Alliance gold members and none of them even bothered to come and acknowledge our status and make us feel special. Seat is in need of a major overhaul. It’s simply outdated and the TV screen is far too small. Food and drinks selection was very sub par.

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.

OK they lost my hold luggage but notified me straight away. My main complaint, after losing my suitcase, I was told my cabin bag had to go into the hold because of it’s size. I, obviously, didn’t want this to happen bearing in mind what happened to my suitcase and when I voiced my concerns I didn’t get an explanation I was just told it would be taken from me on entering the aircraft. Looking around I was surprised to see many passengers not only with larger bags than mine but sometimes two or three bags,taking them onto the aircraft. In the end, nobody bothered taking my bag off me so I just walked on with it. The whole procedure was disjointed, poorly explained and not terribly efficient.

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.

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.

I'm a United 1K member and have ben for 10 years. The gate agent had no control over the boarding process and had us passengers queued for hours as delays were announced. On the plane, the overhead air nozzle was broken so col over was powering through on me and the passenger next to me. Not a great experience for a million miler on United. Feel free to contact me. Josh Smigel - DM426089

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

It was perfect! United Airlines staff was extremely caring, super friendly and professional

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

United has maintenance issues and can then never recover. No operations ability and simple issues always turn into multiple hours long cascading delays. Worst airline on earth.

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Everything was the best it could be. Crew found me with pre- ordered food. Excellent experience!

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

When you consider the price I ended up paying for everything. This was not a good deal! I had no idea that this airline had changed to a bargain basement no frills airline. So, it was disappointing to have to pay for every little thing. The only thing included was water and coffee. You have to pay for everything else! So I just felt nickel and dime.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

The movie choices were poor. The worst problem is the treatment of passengers durinng pre-boarding. In one case the primes were checked in and sent down the boarding tunnek only to stand waiting there while the plane is cleaned. In the second case the bus was loaded, the doors closed and just stood there unmoving like sardeines in a tin for over TEN minutes. In both cases it was rough on us old guys who find standing for long periods trying.. In other words, Donnt just stack us up and forget us.

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

This Condir premium economy is terrible. All it is is a few extra inches of legroom in an economy seat. British airways premium economy is the same as a first class domestic seat, wider with more recline. Plus the flights were all late to leave, arrive, etc. terrible day.

Absolutely the worst food I ever had on any flight. Half of passengers simply didn't eat their meals, as I noticed.

Food could be better. Service was just ok without any enthusiasm...

The breakfast snack was horrible. No nutrition value. I couldn't finish it. The main meal had no taste, no real vegetable, the brownie had no chocolate taste., I was not even sure what the salad consists off.

Breakfast was terrible. Sugary yogurt, inferior pastry, poor quality fruits. No protein.

Our connection in Frankfurt was the worst ever. No one from the airline or the airport seemed to be bothered to get us into our connecting flight on time! The procedures at the airport took us forever and we barely made it into our flight. If we had missed it, I’m sure we would’ve missed our cruise. Looks like everything is on autopilot and no one is interested in helping customers anymore especially us 69 year olds

Crew was very responsive to give soft drinks etc.. At Frankfurt Airport Special Assistance did a great job for us. The seat cushions were simply bad and not up to the mark for Premium Economy which we chose. All the cushions from Business to Economy were poor. Also, any snack besides lunch and breakfast, you have to purchase including chips and chocolate. It is simply cheap. I don't think I will fly Condor anytime soon

The short leg flight was fine. Crew and airport were nice to allow special assistance which helped.

Planes are new and clean and staff is attentive. Food wasn't great and chair cushions were very uncomfortable for long haul flights.

The boarding process is a nightmare. They put you on a bus for 30 minutes with no air flow. The process was extremely slow and we were behind schedule so they auto rebooked us on a flight for our layover. The new flight was 4 hours later in the day, we landed an hour and 45 minutes before our layover flight so this was completely unnecessary. When I called to get us back on the original flight the support staff was useless
