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

8.0 ExcellentAnonymous, Apr 2025LAX - DEN

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

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

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

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

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. 👍👍

Compared with other carriers business class for an overnight was not worth the extra expense.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

The staff were the friendliest I have encountered in years. Absolutely great!

Plane changed to one with no entertainment system or ability to serve hot meals

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Terrible. First my return flight was rescheduled to a terrible itinerary. Paid for window seats where there was no window. All of my seats were mediocre or terrible despite paying in advance for them. Zero onboard entertainment- it didn’t work or wasn’t available. If it was available there were zero instructions provided. I also didn’t like being forced to check my carry-on luggage. Delta screwed me around on the way home with a 2 hour flight delay that caused me to miss my connecting flight so my luggage did not come home with me but had to be shipped on a later flight. Just grateful they found it. But Delta attendants lied about the delay - a supervisor at an info booth assured me they would compensate because it was the fault of the pilot arriving over an hour late but when I went to the boarding gate to get help with this they insisted it was a ground problem in Toronto and not Delta’s fault BUT another flight to Toronto was going around the same time with no delays and West Jet agents in Toronto said there was no notice of any ground delays at the airport (which I have on video). When I went back to the info desk to find the Delta supervisor she was gone. I had to run through Toronto airport asking any availabile West Jet staff I could find to book a new flight home as I didn’t have a connecting flight anymore. Baggage wouldn’t help OR give me my bag back. Because we were one of the last flights into the airport all staff had left. I finally decided to go through security to find an agent at a boarding desk and was lucky to catch one before she left to get booked onto the next flight home in the morning but I still had to spend the night in the airport. It was awful!!! I was scared, travelling alone and desperate to find help - which was a extreme challenge. Maybe 2 out of the dozen people I asked were pleasant. The rest difficult. I felt betrayed. Oh and I kept getting directed to the information desk in Toronto airport but no one was on staff and I used the phone to try calling someone but I kept getting useless recording. I will not be flying Delta or West Jet again. It will be a long time before I feel safe to travel again. Many tears. This was an awful and highly stressful experience.

Good. Would be better if the carry on baggage was free.

Lots of delays and a broken plane, would not recommend

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

Westjet is one of the worst airlines in the world. 100% guaranteed to have flight delays and flight cancellations. Will never book again with Westjet.

Westjet is the worst airline. If you fly with them, you can expect 100% delays or flight cancellations. I support all Canadian, but not Westjet. They are terrible at what they do and will avoid them as much as possible.

Plane should have entertainment, instead of people paying to use wifi

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

No Charging ports for personal electronics, which were required to use wifi entertainment.

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone

Plane was old, cabin was small, overhead bins were small, seats really uncomfortable, no seat-back entertainment

Excellent crew, great food despite catering issues. We need more people like this.

1. The PA system was painfully loud. 2. Overhead bin #33 was missing—I find this troubling.

I had a disappointing experience at the San Diego airport with one of your gate agents. Despite being in Zone 4 and traveling with a standard carry-on bag that has never been an issue (30 flights in Q4 alone), the tall, blonde gentleman forced me to gate-check my bag. When I politely asked if we could verify the bag’s size, he became confrontational, even threatening to deny me boarding twice. His behavior appeared erratic and unprofessional, projecting a negative attitude onto passengers, as if he was going through something mentally. Notably, there was ample overhead space once all passengers had boarded. In contrast, the tall, older Asian agent handled the situation with professionalism and calmness, making a clear effort to de-escalate. As an avid traveler, this unnecessary inconvenience set a frustrating tone for my trip to Asia.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

The flights were in time and the bags arrived. well done

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Overall good. I was surprised how easy it was to get from plain to plain in such a short time. Food choices were not so great and quite expensive. Entertainment was ok. Flights were smooth.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(
