Good flights. On time. They had a gluten free snack option which was nice

Take this flight once or twice a month. Just don’t cut it from the schedule.

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

This is speaking of the original flight leaving on April 30th(DL 1957) not the rebooked the following morning DL 9887. On April 30th, it was unusually crowded at Sangster International Airport (MBJ) the morning my mother and I arrived for our flight. She had to exceedingly long time for a wheelchair, once a wheelchair attendant arrived to take us to thru immigration and security then to go to gate the flight was boarding. We stayed on board for 3 1/2 hrs until the flight crew notified the passengers that flight indefinitely delayed so we had to stay by gate area. Before that my mom had to wait an additional 20-30 mins to deboard the plane. Was given food vouchers, by the time I came back the gate agents said the flight was gonna to reboard, so all the wheelchair passengers lined up. We waited an additional 45 mins, while I received a notification from kayak that the flight was cancelled. And on my delta app updated that flight was being detoured to Miami then from Miami back to JFK. We boarded the plane started to eat, then the flight crew notified us the flight was indeed being detoured & that how come the gate agents didn’t notified the passengers. We stayed on board for another 30-40 mins then was told by the captain that they tried all avenues to get the passengers back to JFK but the crew couldn’t continue the journey and the flight was cancelled. So we deboarded the plane again. Was told that we were going to be setup in hotels for the night. The hotel that we setup to go to wasn’t suitable for my mother’s needs and requested one nearby we were located in Jamaica. So any we had called a taxi to come to take us back where we stayed in Jamaica, that we had to pay out of own pockets.

Food from the flight from Atlanta to Santiago was very poor..

Flight was delayed due to weather. Crew did a nice job of making us comfortable. No complain complaints.

Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

The service was great. However the lounge only gets passing grade

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

The flight was cancelled due to tech problem with the plane

The whole experience was very disappointing. Drinks could have been served and offered more frequently. The seats were reasonable but considering I paid for premium economy, I felt cheated. I flew premium economy with Japanese Airlines ANA 5 years ago and their service was by far, superior. We had access to the club lounge, better seats and excellent service. Out of 10, I would rate the experience as 4. Everything felt cheap and the Airbus aircraft are far better and more comfortable

Flight was okay however bags were left in London even though we had a 7 hour layover. Bags are yet to be confirmed to reach final destination. Horrible work.

Quiet and comfortable aircraft, pretty smooth flight. Very comfortable business class cabin with decent entertainment. Good service from the crew. All in all a good experience.

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Too much long line at the TSA and Security. Prepare for long walk for baggage claim.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

The boarding process was quite loud and chaotic. The flight attendants kept barking over the PA system about people needing to only stow large items in the overhead bins. During the one and only service, I was hit by the service cart. At the same time, a passenger was returning from the bathroom and the crew definitely saw him but stopped a few seats short of allowing him to sit down before starting service and made him wait a good 10 minutes before passing his seat and allowing him to sit down, after which he had to ask for his snack and beverage or he would have been passed over. Neither flight attendant thanked passengers as they left; in fact, I did not see them again once the plane door was opened.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The worst, flight cancelled because the aircraft was not full. Heathrow ground crew totally not helpful and arrogant. Lady proposed us flight with 40min layover instead of direct and said it is our problem of course she was unable to do anything as everything was beyond her control she claimed. after calling on hotline another flight was booked. Flight was cancelled last second so we could not take direct from Zurich but we had to stay overnight in London.
