I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

They split our family into two trips due to flight overbooking. Horrible experience.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

It was not Iberia. It was with United. It was great!!!

Our flight was delayed by 2-hrs but I understand it was beyond the scope of the crew members

I am quite satisfied. The flight was on time and landed early. Staff was friendly.

I could change to business before flight and everything was perfect except for entertainment which was none.

Needed more info on connecting flight. Late flight made very short connection. Lost luggage that we still do not have!

Seats comfortable on economy plus and attendants very helpful. Food was ok. Bathrooms needed servicing.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

I liked the friendly crew and desk staff, all very helpful. I was surprised and a little annoyed on my outbound flight from LGW to MCO as I had prepaid and booked my seat, which was all correct at check in on my boarding pass. when I got on the plane someone was in my seat ! I was moved to another seat. The food choice is quite limited and I feel that an option of a muffin for breakfast snack would be welcomed, not everyone wants egg or bacon wrap. The choice of entertainment is good, plenty to keep you busy on a long haul flight. I liked the option offered to have the cabin bag checked into the hold, it saved me as an older, lone traveller lifting my case into the overhead locker or finding there was no space.

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Non stop flight from Barcelona to Rome, arriving on time.

3 hr flight from Barcelona to Gran Canaria. Ŵent according to plan No issues with staff oŕ flight. Many people includiñg us could not get luggage self checķ in termìnals to work. Had to wait in check in line.

The communication about the delay could have been better before and during the flight. Also, this online form could have less bugs. It is almost impossible to type in this window.

We got to the airport 2 hours before the flight. We waited in a line to check our bags onto the flight for an hour, even despite having checked in online, as there weren't enough self check terminals allocated to Vueling (yet loads of empty BA ones right next to them). There also weren't enough staff, making them stressed and rude. We had to try and rush through security to get to our gate, which they announced as gate 35 at first and then changed it after ten minutes with no announcement to anyone in the airport that it had changed. So we then had to rush to the correct gate to arrive just as boarding started. It was a thoroughly stressful process and one travelling couple almost missed boarding because of it. The flight boarding and the flight itself werre fine, the staff were polite, but I was dehydrated due to the airport and had to buy a bottle of water as they didn't offer free drinks.

Bought check in baggage but couldn’t do it at the kiosk, had to line up just to get baggage tag which was a very long queue with only 1 customer service agent handling all vueling flights. Had to wait about 45mins just to get a bag tag and drop baggage.

You have couple of KG's grace on checked luggage

Last time bucking this company if I would know I wouldn’t do it, they made me lose my flight

The baggage policy is pathetic. We paid for our carry-on bags online. Said if we don't remove the wheels of our carry-ons it's not considered a carry-on. We all measured our bags according to the website beforehand. We were not refunded for our bags and were obligated to buy it as checked in bags for over $70 online or $90 over the counter. First and last time I travel with this airline.

Because the scale includes two terminals, we almost lost our flights. That data was not referrenced to us. The check-in process was a pain too.

The whole checkin process was a diseaster! We were flying with Vueling! We had checked in on the app but still had to checkin at the desks with our 10kg hand luggage! The queue for this was 2.5 hours long, with no social distancing in the pandemic (Covid19). When we finally got to the top of the queue, our flight was closing also another queue was opened up! But if we left the queue we were in we would have ended up at the back of a different queue! This seemed pointless to be honest! What could have been done is a bag drop section of the checkin process (Like Ryanair has) it’s much more streamlined and quicker! After all this drama, we only had 15mins to make it through security snd passport control to make the flight on time! It was very stressful and very hot! I was so thirsty that I needed to buy a bottle of water at the boarding gate (to my surprise this small bottle of water was €5- a total rip off! After boarding (which was ok) we were looking forward to a nice cup of coffee on the flight as we usually do! It took the crew nearly 1.5 hours into the flight to get to our seats to serve us! The coffee was dreadful (a hotel type sachet of instant coffee costing €2.60) and a heart burn inducing Turkey, ham and cheese toastie (costing €5.50)! The horrified by the quality! Ryanair is definitely better on food quality, check-in and boarding experience and service, that’s saying something! The flight itself was grand (although lacking interaction from the pilot- which is always nice) it was a smooth flight! When it came to landing it was good but our baggage took nearly 45mins to come out onto the carousel in the terminal! And other delay! Overall I would be giving Vueling perhaps a 2 out of 5 overall! Not impressed!

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Boston Logan is a crummy airport - signage is terrible or lacking in areas. Boarding seemed to be a free for all and with all the different airlines speaking, you couldn't tell who was supposed to be where and when. Plain and simple, airlines should board from the back of the plane to the front. Also someone was sitting in my seat. By the time that was figured out, I had to place my overhead behind me which made de-planing more difficult. Logan is not Lufthansa's fault so that is not on them, Boarding is on them! Still, overall it was a Good Experience flying with Lufthansa. This is not my first flight with them...

Overall, the flight was comfortable without any serious issues. Transit through Frankfurt airport was a little confusing, but not too difficult if you follow the signs

There was a screaming child behind our seats. This prevented us from getting any sleep during the night.

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

Staff disappeared after dinner service until breakfast, no help with beds, no help running to our gate to catch connection cause flight was late, our luggage didn’t make it, took over 24 hours to get luggage to hotel, no compensation!!

Everything was good except food. I believe there is room for improvement

Houston to Porto flight delayed landing made us miss our connection. Tried to get on standby for the next flight and even though the lady knew we wouldn’t be able to get on it and she sent us down there. We sat there three hours and then we’re told there’s no way you’re getting on this flight. So we had to go to customer service and ended up having to spend the night in Frankfurt and missed a whole day of our vacation in Porto

my flight was at 3:45 after that they delayed to 4:40 I have transit from Chicago to Frankfurt and Frankfurt to vina airport from vina to Erbil buy the Time I come to Frankfort my other flight left me I have to stay at airport all day with my 5 kids ask for help no one help me I spent at airport almost $450 just for food was horrible flight ever I call and ask for hotel from united customer service they been telling me we can’t provide any hotel I need some refund or fixed my flight when I return to America need some one respond my email

It was a short haul trip, so food and entertainment weren’t a big issue

The plane seemed very dated. The entertainment was very limited. There was a school group on our flight and the crew seemed bothered by them. They were not overly friendly or welcoming.

Ok, but no entertainment. Left late, but made up most of the time.

May be it is not an ITA issue, but the bags took long time to go out.

Good. But there food was poor quality and 95% of movies didn't have English subtitles

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

Service from staff was poor, food choices were limited. Air plane was not clean or hygienic and seemed like not cleaned for days. Seats were uncomfortable.

service from stAff was barely there , food choices were limited. AirPlane was not clean and seemed like it was not cleaned for days.. Seats were very uncomfortable.

I paid for premium seats and the last minute they changed the aircraft for a bigger one, they bumped me to another seat which was NOT at all comfortable for an 11 hour flight, will fight for a refund!!

The landing was catastrophic. I was very scared. I thought it were my last lminues. Pilotes should be more experienced
