The entire experience convinced my wife, Cathy, and me that traveling Polaris on United is the only way we’ll fly in the future. From check-in and baggage drop to the end of the 12-hour flight, the customer service was exceptional, with numerous staff members exemplifying the very best in care. On board, Andre, our primary crew chief, was sincerely friendly, a consummate professional, and, along with Freddy, one of his team members, truly among the best of the best. The captain even came through the cabin to chat with passengers—a wonderful personal touch, especially on such a long journey.

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

The first flight was an hour and a half late leaving, thus missing my connection. The second flight Departure was two hours late Leaving.

The width of the chair is very small. Not comfortable at all.

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

one hour to board connecting flight from frankfurt trying to beat the far Z gate and with immigration of USA ppus waited for delayed boarding in gare for an hour and fly half gour late worst transit im frankfurt this airlines are for profit passengers are victim of dysfunctional airline frankfurt so crowded restroom are too small

Seats were very comfortable and everything was in good working order. Crew was disengaged to the point of being rude.

Based upon our entire experience with Iberia, we will never fly the airline nor recommend the airline to anyone. The flight to LA was fine and the crew on this one flight was god, but Iberia treats its customers (us) horribly. There was not one flight on this trip that they did not treat us poorly. We were bumped, lost seats, lost luggage etc all on flights we booked over a year in advance. Not one leg with Iberia went smoothly. And now they have lost our luggage somewhere in Madrid. This is a horrible airline. A truly horrible airline. And Underpricer recommended by Kayak is horrible as well. The lesson learned is to book directly with an airline and stay away from Iberia at all costs.

Boarded in group three at Barcelona, which meant going from a gate outside onto a bus to ride across the airport to a plane waiting on the tarmac. When we arrived at the plane, crew behavior told us something was wrong. Bus driver would not let us off for almost twenty minutes, despite being crammed shoulder to shoulder. Eventually, we got onto the plane, but were then told that someone “forgot” to refuel the plane and the truck to do so had not arrived. We departed late enough that we missed our connecting train in NYC, which was the last train of the evening, so we had to stay awake all night in the passenger waiting area of Amtrak’s Penn Station, which was almost impossible to get to because the station was now closing, as it was after midnight. We had to haul four suitcases a few blocks on city streets in the rain to get to the one remaining open entrance to Penn Station. We ended up being up for 36 hours straight because someone couldn’t do their job. Never, ever again would I fly this airline.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

I originally chose two aisle seats for my daughter and myself in the same row. We got seated in the middle, three rows apart. Both of the men sitting in front of us reclined their seats fully leaving us NO room. A totally uncomfortable flight for eleven hours.

No entertainment and WiFi for a 13 hour flight is outrageous. Old plane. Broken seats and toilet of order. To have to pay for food and a blanket under those conditions is ridiculous. We are never flying with Level or Iberia ever again.

We had a seat that would not function. No Wifi or inflight entertainment was available. Food was very poor. Attendants were very accommodating and apologized for the problems.

Booked with Iberia but flight was with Level. This switch of airlines was not published anyware and I was not made aware. Service was horrible, attendants were rude and nowhere to be found. Interior of plane was disgusting and dirty, trash on the floor, bathrooms were dirty (probably because flight attendants were not collecting trash from passengers). I have never encountered this on any other flight or airline. A public bus or metro in Los Angeles is 10 times cleaner. Had I known this was not an Iberia flight I would not have booked this tickets.

We flew Level for the first time direct from Barcelona to San Francisco, and wow, we were pleasantly surprised: large, comfortable seats in economy class, the crew were very friendly and polite the entire trip, and the food and entertainment options were great. We would absolutely fly them again.

Flight was assigned to Level Airlines and meal information was not provided to Level. Level flight attendants refused to serve meals to our family because it was not indicated on our tickets.

Good and they are leaving at time and arriving on time

Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Come on. A two hour, 7am flight and a small bottle of water and a tiny chocolate bar was provided. No coffee, no nothing. Poor.

Plane was crowded, seats narrow, legroom nearly nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to repair it. This flight was in direct contrast to a very comfortable Lufthansa flight from RDU to Frankfurt about a week earlier.

Rushed due to connecting Lufthansa flight delay Seating very tight and uncomfortable with poor leg room Long lines for rest room

Better when flight announcements are better produced and slowed down a bissele

My only complaint would be that we paid for insurance in case we needed to change our flights. However we still had to pay to change and was not helped on either travel parties. I would like a refund for my change fees as indicated in our insurance plans.

Le personnel attentionné et trilingue, la tranquillité du vol. Aucun aspect négatif

The only really annoying part was the TV screen. It was kinda messed up. Like it would just randomly turn off or switch. It was also not responsive. Which gets annoying on an almost 12 hour flight

Luftansa over booking canceled my flight 2 days before I left, so I called to reschedule but didn't answer, so I had to cancel. This has ruined my vacation plans and I already had to pay 3 days for a hotel reservation in Barcelona. I don't think I'll ever book this flight again in my life.

Missed this flight. $5000 to rebook next day. Horribly rude staff in Frankfurt. Everyone we encountered was either not helpful or outright mean.

Condor's computers do not work. They do not leave enough time to catch a connecting flight. Condor had to book passengers on a different airline to make their destination. They lost my niece and nephew's luggage. The bathroom had pee all over it before the flight took off.

Premium economy meant only extended legroom and when the passenger in front of me leaned back, I lost the little space I paid for. Food was not great. Movie selection is okay. Feels somewhere between a mainstream and a budget airline.

The jet is quiet but the food is uneatable and the new seats are horrible .One cannot find comfort on them. When do airlines learn that there is a better service for your clients. Go to a flying wing design save fuel offer a human seat where your arm does not interfere with your neighbor . Provide food that tastes good and offer free drinks

One of the female flight attendants had an attitude. The snack toward the end was pretty bad. My husband and I were both sick the next two days.

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.

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

It’s a budget-friendly airline, so expect smaller meal and snack portions and no free alcohol to drink on international flights. Airline food is never exciting in economy class, so I always plan on taking my own food and snacks- and I don’t consume alcohol, so no complaints from me! Flight attendants were friendly, attentive, and helpful. The airplane was newer with USB a+c charging ports, massive infotainment screens, and a lot of entertainment media to choose from. The airplane seats are less padded than other airlines I’ve been to, but the benefit is that there was more legroom because of the thinner seat profiles. Honestly, more legroom gave me more comfort than having more padding on a seat (which just gets flattened over time and repeated use) Overall, I really liked my Condor experiences (4 different planes) from LAX-Frankfurt-Barcelona and back. I would not hesitate to fly with them in the future, if the prices are lower than other companies

It would be nice to have a cleaner facility, it was hard to access it. It was always full of people working in that space. The covers and especially the matt of bad quality and old. Many times reused. I would not use it. Food: the bread rolls were old, and food had strange choices. Chicken was terrible.

One of the stewardess was really rude to a customer right near me. I ordered water and was given sparkling water which kind of surprised me as I've always been given still water but I didn't say anything. The lady after me ordered water as well and when she saw it was sparking water, she stopped the stewardess who then said very curtly "You could have told me sooner." Whoa...that was rude! Later this same customer had some liquid spilled on her as the same stewardess handed a drink to the person sitting next to her. I know it wasn't intentional, but it was rather strange. It was very hard to navigate how to get through the Frankfurt airport to our connecting flight. No one told us you'd have to go through security again so it was rather confusing as we didn't have a boarding pass. Luckily we were able to get necessary papers and get to our flight. Sadly, my luggage did not make it out of Frankfurt though.
