Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Bottom seat cushion is almost non existent. Very uncomfortable seat.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

The seats are uncomfortable, feels like a small seat pad on plywood.

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

Long line to check bags. Curbside check-in was closed. Seat back monitor was not working.

New boarding doesn't make sense. Filling front first is slow.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

Love delta but the delays and long waits for updates was just too much this time.

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.

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

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.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

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!

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.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

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 .

Very good crew. Food service above average. Seats very small for a 12 hours flight.

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.

Our flight was canceled for a reason that suggests gross mismanagement. We were re-booked for a flight to a different airport.

Worst: long walk to baggage claim Best: left on time

Great overall experience with TAP - would not hesitate to recommend for your next trip to or from Portugal

When I tried to enter my identity details, your app told me information was missing but did not highlight the missing data. This was frustrating. Also, there was an unexplained delay of about 2 hours in taking off. This was also frustrating. Otherwise the experience was good.

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

My seat was broken and unable to fully recline. My USB power point was not working and nor was the one next to me. It made a 12 hour flight feel a lot longer.

Gate closed way too early - over 1 hour before departure. Put onto next flight. Ticket had been changed without notifying us.

Boarding in Dallas was hell with extremely rude gate agents , especially a lady named Rajathi who was the epitome of rudeness with no compassion at all . She was horrible and I wonder why airlines have people like her on their roster who exude arrogance and haughtiness . Will probably not fly British Airwsys because of people like her .

Aer Lingus was the actual airline so they handled everything professionally.

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

They lost my special meal request and tried to tell me I didn't request it. I had the proof. Then they tried to get me to eat food I can't eat. No apologies

The flight from Porto was delayed by 3 hours. Arrived in the US late at night. Exhausted from all the waiting. And staff did not communicate well with customers.

It was a great experience. I did find that some menu options were not available, which was a bit surprising, but over all a wonderful experience.
