This was the 3rd time in a row that my flight was late leaving or canceled. Other airlines seemed leave on time.

This was the 3rd time in a row that my flight was late leaving or canceled. Other airlines seemed leave on time.

The flight was delayed multiple times and then finally it was late by 5 hours. I tried to be patient and then when I finally asked if there was an earlier flight to LA, I had just missed it. I would have appreciated an updated text or something to let me know that was an option earlier. It would have been better for me to get a bus to L.A. with that time!

The original flight was canceled, but thankfully the airline made an effort to rebook to a later departure. However I lost a day and had a layover in LA. My original seat which I purchased was no longer applicable on the new flight and there was some kind of bulkhead that forced my legs to the left. This is more an Airbus thing than anything else. In flight entertainment system was hard to navigate because screen was not calibrated. Pluses: rebooking by the airline Didn't have to claim my luggage for the transfer. Minuses: lost original seat purchase IFE was quirky Did not eat Original flight canceled Weird bulkhead in way of legs

Liked the flight was on time. Seats and leg room need major imptovement

Alaska prevented me from selecting a seat and was only assigned a seat at the gate. This gave me unnecessary anxiety prior to boarding. Several 15-minute delays (probably weather though no explanation was provided) eventually pushed departure back by one hour.

Gate agent was VERY efficient, even as his 2nd wasn't there. But... Great Landing! (I suspect he's done this before.)

For a 6 hour flight better snacks at least bag of chips should be offered all we got was connamon pretzels going and coming back nothing but maybe bc it’s an overnight.

Our flight was experience was great. The captain announced what to expect on the flight. The weather was stormy in Florida our destination and he explained we would be going thru some turbulence but all would be good. He took time to announce when we flew over notable areas of the country. Flight crew was good. The snacks need to step up. One Biscoff for a five hour flight on a $650.00 ticket is slack.

Sort flight, helpful staff. A special thank you for allowing me to board early, I'm almost ninety and I have problems lifting , was able to get done. Thank You

Boarding was well organized, seats comfortable & it was a very pleasant flight

The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Terrible airlines, kept lying to me about the fact that my connection flight was cancelled. Left me hanging until last min. NEVER AGAIN

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

I was surprised how good an American airline can be - I was really impressed.

Over all experience was good. However the connection time was too short at CPG. We missed our connecting flight to AMS as the passport control line was too long and by the time we got our passport control done it was too late I wish there were some SAS staff to help us out at the passport control center Though they put us in a KLM flight from CPG to AMS, That flight was also delayed by over two hours

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

Business class seats narrower and the most uncomfortable Business class I've ever experienced. Clothes on the seats was itchy, head of the bed was elevated causing us to slude down even though they were "lie flat seats". Plane was way too hot. My partner and I were both sweating just sitting in our seats. Staff appeared sad or depressed

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

One of my checked luggage was damaged. Cracked on the top by the handle.

Not so good. Crew was not as attentive as they should have been especially if flying business class. Only offered dinner 2 hours after takeoff. My flight attendant seemed overwhelmed. Pushed my help button but no one came. I explained everything on my previous review.

I have been flying united for a long time but now I’m done

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.

Flight was over two hours late, but they notified us early in the morning. They ended up changing planes the food on board that was extremely mediocre and we were in premier class.

Food was very bad Crew was not so welcoming. Chairs was so uncomfortable

Due to delays at SFO, my WestJet light missed its connecting WestJet flight. If they had held the plane in Calgary for 15 minutes, 2 families with children would not have been stranded in Calgary for more than 24 hours. I understand the need to be on-time, but when it is the same company, you would think they could make a phone call. Or maybe they could go to a higher altitude to make up for lost time? Instead of attempting to put us on another flight, they rescheduled us for the same connecting flight 24 hours later. We then had to scramble to find a hotel, which they state that they were not responsible for since the delay was not their fault and therefore became an additional out of pocket expense for us. The customer service is severely lacking here at this company. They also mentioned that if we purchased our tickets through a 3rd party site (Kayak) versus WestJet directly, that they couldn't help us. Seriously?? Additionally, we lost 2 days of travel and missed out on tours and taxis that were pre-booked. I will not be using WestJet again,

They lost my bag. Hopefully it will be here tomorrow.

The trip from LAX to Calgary was aboard a 737-700, which is more than twenty years old. Service was fine, and the food was good, but there was no inflight entertainment, and no WiFi. The flight from Calgary to Vancouver was also delayed more than an hour, due to congestion on the Calgary tarmac. And no food service, but there was in-flight WiFi which made a big difference.

Kayak was the problem! The tickets we bought did not allow for carry on or checked luggage and we ended up paying more for those services than the tickets! The paperwork Kayak provided for the receipt left the luggage policy for Westair intentionally blank. This was intentionally decietful on Kayak's part. Our additional cost was over $400.00! I will be calling customer service today asking for refunds and I will keep you informed on any review sites as I can. Keith

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

The flight was on time - which is good. But pretty much every other aspect of the experience was bad. They charged 55$ for a carry on bag!

Flight was old and the seats were not comfortable at all. They made me pay 55$ to take my carry-on bag onboard.

The seats were very comfortable. However the meal on the transatlantic portion of the trip was not very good, even by airline food standards.

They made my minor daughter leave the area and go back though security during a flight connection with her checked luggage

Only coffee, tea, and water were complimentary. Seat did not recline.

Overall professional and reliable; only complaint was the lack of complimentary food or beverages on the flight. I’m not accepting an upcharge on things one can reasonably expect.

Movies were old and third rate. Very poor on a seven hour flight. Food was OK but not business class caliber

Although the flight from JFK to Keflavik is not inexpensive, Iceland Air offers nothing but water, no soft drinks, to passengers without a charge. The seats are uncomfortable, there is no leg room, and there was no available internet to purchase.

Was hard to sleep, but other then that everything was good.

We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.

Hard to figure out how to put back the seat, how to get the entertainment, how to upload passport docs. Also, a warning in the airport that food was all for purchase would have been helpful.

Horrible. My dad was recently hospitalized and diagnosed with lymphoma and Icelandair refused to refund flight even though I had a letter from his physician.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.
