The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Klm start boarding while somw air issue in the plan

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.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

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

Food was terrible. Crew was kind but skipped over my row for providing sandwiches and beverages.

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.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

David went above and beyond to make our flight the best that it could be

Cabin crew was very friendly, requests were satisfied promptly and cheerfully, and the cabin was reasonably clean when I boarded. The United lounges at Newark and Heathrow are always well-run and comfortable, especially Newark. I look forward to the new lounge that will be part of the rebuild of Terminal 2 at Heathrow.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

The 787 Dreamliner that we flew on was relatively new and a nice aircraft. We flew on a 777 which was noticeably older and the seats were average” but the 787 was very nice, especially for the price. No window blinds anymore, instead high tech adjustable polychromatic glass!! Nice.

Most courteous, helpful employees and all flights were on time.

an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Everything was very good, short delay Toronto to Regina on my return to Canada but not a big deal. Thanks Kayak, Dr. Ian Stewart

Boarded smoothly, took off on time. Entertainment screens were reliable and the movie library is abundant. Food better than wtst was served on the first leg of the journey by another airline.

Check in was incredibly fast, fukuoka was comfortable and crew very pleasant. The only negative was that the boarding was somewhat chaotic, but it so often is these days as airlines tend to board by how much you pay and not by what an orderly process of filling the plane would be.

It was ok. Even after the airport bus took us to the terminal , we did not expect to walk 35 mins inside the airport to the gate . A 15 min walk is ok . Especially if there was any delay in TSA check which happens to is too then people can easily miss the flight.

Excellent bit seats are still a little too small and there's that $75 baggage charge.

Very disappointed with how we left Heathrow, and the service from Air Canada. When food was given, I was skipped by the attendant, and when I went to tell him, he just dropped the tray of food on my table. Leaving Heathrow and landing in Montreal were bad, which is not Air Canada’s fault, but the service itself was not good.

We had a lot problems in beginning but Air Canada took very good care of us

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

The plane was late (as was my flight out from Birmingham the day before)

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

The flight was delayed by an hour. Made the connection uncomfortably tight.

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.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

No food, terms when selling are not clear. To pricy for the service in general

Seats are very tight even in Plus, no complimentary snacks or beverage

I receive a service for what I pay, so it is fair.

i think the flight was late because they were so strict about measuring everyone's personal items to try and charge them $119. It was really petty and made us late.

Business class seats did not lie flat. There was only powdered milk for your coffee....in Business Class!! Food was good.

The seats were very uncomfortable. I would have upgrade or got different flight if I knew. I usually sleep in the plane but I couldn’t sleep at all. Very uncomfortable. Also no food or drink everything was to purchase, and that’s u usual for international flight.

There isn't much space in-between seats and even water needs to be paid for during the flight.

We were not aware carry-on bags cost extra until we arrived at the airport so, we were charged $240.00 for two small carry- on bags! There was a substantial fee for drinks and snacks. No wifi, or other entertainment was available. Waiting areas were crowded and uncomfortable.

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

Be very careful of the initial low price because Avianca wil bill you for a carryon of $120 or a checked bag for $120. Also, be careful with connections because the customs entry process is slow and the connecting terminal is not close.
