Check in was quick and easy during early hours. Flight was on time, and customer services was a plus.

Check in was quick and easy during early hours. Flight was on time, and customer services was a plus.

I understand that the food on the airplane wouldn’t be fantastic. However, it wasn’t good at all. 😭

The flight was comfortable with the exit row and great service

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Ok. Get a different kosher caterer. The food was odd.

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

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

1.It will be better if sandwich is warm. 2.The food is too salty. 3.Breakfast needs some vegetables or fruits.

Very fast boarding. Crew members were super nice. I loved it!

My luggage got lost and until today there is no solution to the problem. It's still missing

I am writing to demand an immediate refund and compensation for the absolutely unacceptable experience I endured with VUELING this week. On Monday, my flight was canceled, and despite this, I have yet to receive any refund. I was then taken to a hotel in a terrible location, where no food or even water was provided. The next day, I was rebooked on another flight, for which I had to personally cover an additional €50 in transportation costs—only to have that flight canceled as well. After waiting 10 hours, only 10 of us were offered alternative accommodations, while the rest were left stranded. We were forced to remain in this situation until Thursday without a single explanation or proper assistance. During this entire ordeal, we were only provided with breakfast and dinner, while being charged extra for drinks. This level of treatment is completely unacceptable. I expect an immediate refund for the cancelled flights and full compensation for the inconvenience, additional expenses, and the significant distress caused.

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

Nothing. There was no flight. They cancelled the flight with no replacement about 9 hours before takeoff.

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

Boarding with some sense and communication. It was a total free-for-all everyone coming all at once, no organisation of row numbers or priority.

Horrible, flight cancelled and had to come back the next day

Terrible. For clarity - this was the Level flight to Boston. Not Vueling. Would urge customers to avoid this airline. Gate agent was singularly unhelpful. He was argumentative, rude and went out of his way to ensure that every penny was collected for the baggage (which we realized given how early we were for flight we could have saved hundreds of dollars if we checked in on app). No onboard entertainment or WiFi. Half of the front section was empty because the seats did not work! Plane was falling apart.

temperature was too cold there should be free blankets, seat are very uncomfortable, entertainment is limited.

It was hidden that I needed a special fee to bring my guitar on. They charged me an extra 69 euros at the gate and did not refund me the checked bag I paid for and the over head bag I paid for which I didn't use because I had to pay for the special guitar case. Criminal behavior. They were very unkind about it as well. Terrible experience. I'd like my money back for the extras I paid for.

Basic service for a decent price, all amenities are à la cart

It was extremely cold in the back of the plane. The seats are uncomfortable and space very small. Crew was excellent as usual.

The plane needs upgrading, the seats are uncomfortable, we are a family of three and they split us and did nothing to group us together, and the food is horrible compared to other airlines bu

Horrible almost missed my flight because my 1st flight was delayed. Airline crew is so unprofessional. The people on the plane do whatever they want kids running screaming. Will never fly this airline again Suitcases never arrived

Horrible experience airline crew was unprofessional. Flight was delayed. Suit cases did not arrive. Never flying iberia again

Chairs do not recline. Finished the trip with an aching back.

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

It was chaotic. It was overbooked so we didn't have seats until the end but they turned out to be good seats. The gate was at the end of the airport. We had to get busses to the tarmac and board. It just seemed chaotic. Flight was OK. Food was not so good. Lufthansa used to be such a great airline and now as it's with everything else: If you have money you get comforts but if you don't then you end up below deck with the rest of the cattle.

Welp - they boarded us appropriately...then had us sit on the plane for over two hours before cancelling the flight...which meant another night in Munich. I probably had it a little better than most as over 500 people had to be accommodated/re-booked etc. The next day I boarded the same flight (for which I had now been ticketed 3 straight days) and - with "only" an hour delay, managed to finally get home over 2 days later than scheduled. I haven't flown Lufthansa to Europe in years...and I won't be looking to do so again in the future. To be clear, though, the people I interacted with - flight crew, Service Center, check-in were all professional and courteous - management is clearly to blame for their lack of communication and unpreparedness for when things go wrong.

It was a short flight, everything was good with it.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.
