For a red-eye flight, it was overall okay. My biggest complaint is that my seat recline was broken and I paid more for a premium seat. That was disappointing.

For a red-eye flight, it was overall okay. My biggest complaint is that my seat recline was broken and I paid more for a premium seat. That was disappointing.

The issue was not alaska airlines. The ticket you printed was innacurate.

Seat 6F was very good, but had loud engine noise

I APPRECIATED THAT THEY CALLED ME TO LET ME KNOW THAT I NEEDED TO BOARD ASAP AS I THOUGHT I STILL HAD AFEW MINUTES LEFT TO FINISH MY BLOODY MARY.

first class on these new Boeings is horrible, absolutely not worth the money, its bad. I need to find a IAD to SFO with an Airbus like Virgin used to have, that was the best ever. I am now only looking for flights with an Airbus

It was prompt. The only problem was that there are electric outlets at the seats, but they're on a slant, so my computer charger just fell out if I wasn't holding it. Flight attendants were fabulous.

Everything went smoothly, with the exception of a two-hour delay on the return flight, which wasn't the airline's responsibility.

As soon as we arrived Ash greeted us with a warm smile, positive attitude, and was incredibly helpful. He again met us at the counter by the gate and prepared us for our long trip to the Philippines. We shared some small talk on the jet bridge as he was passing by. The best experience I have ever had with any airline. Keep up the good work!

extremely bad. crew at the gate and in flight unprofessional, unfriendly , refusing to offer any help

Most everything was as expected, but the flight attending crew were loud and obnoxious.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

Ability to watch movies.No earbud sound system.Marginal beverage service.Unexplained late take off resulting in VERY tight connection in LA which proved maximally stressful.

Ability to watch movies.No earbud sound system.Marginal beverage service.

Great service; lots of water offered, frequent trash cleanup; tasty food

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

The lady at the check in counter wasn't helpful

Crew seemed annoyed by the fact we were there. Very unpleasant

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

WiFi was not working. Zero entertainment. Did not receive a discount etc to make up for this.

Calgary WJET supervisor was the most professional, and diligent official who I have experienced personally to resolve our flight issues.

Flight was canceled last minute and no re-booking was offered. Had to buy a same day flight from another carrier at double the price. I’ll never fly WestJet again.

Don’t actually know how this flight would have been since we missed it.

It was fine. I had a lot of trouble trying to buy a seat. The Westjet website charged me and then didn’t give me my seat. I ended up keeping the seat I was assigned and hope that the charges didn’t go through.. they didn’t. But this problem with the website (trying to purchase a seat at check in) has happened a few times before. But overall the flight was good.

Terrible! Delayed three times, landed at some corner of airport, walked in bitter cold night, took a bus, bad experience

My wife and I had an uncomfortable experience with your WestJet ticket counter rep at the WestJet Priority Member ticket counter at YYC (Calgary) on May 15, 2024. I not knowing this individual’s exact name, however, in order to easily identify her, she was one (of only two at the time) ticket counter reps at your Priority members ticket counter check-in, upon our arrival around 12:15 p.m. She was a Caucasian woman with blonde hair, and wore spectacles, approximate age being probably somewhere in her 30’s or 40’s. Background: After arriving in to the West Jet terminal in Calgary (YYC), I asked a terminal employee where the West Jet check-in ticket counter was. He told me, “Column 16”. My wife and I continuing to walk through the terminal, we finally arrived at the Column 16 area, i.e. this woman’s ticket counter area, which we discovered later was the Priority Member ticket counter. However, I was simply going by the directions given to me by the previous employee, i.e. “Walk to column 16.” Standing in her line (my wife and I being the only people in her line at the time), I tried to get her attention, and I then gestured to her, motioning to her as if to ask her if I should then possibly leave the waiting line in order to then proceed to walk up to her ticket counter. She never really motioned me to come forward. I sort of had to figure this out on my own, as my wife and I then finally decided to walk forward to her station. From this point on, after I arrived at her ticket counter, never once did she ever look me in the eye. She was always looking at her computer screen, or down at the ground, as she and I occasionally exchanged conversation with one another in order for me to be able to acquire my boarding passes from her. Shortly after she began servicing us, she commented that her work section is for Priority members only. Fair enough. I did not realize this at the time. Wishing to be polite, I then mentioned to her that, if I should, I could then walk over to the regular West Jet check-in ticket counter in order to complete the check-in process. She remained quiet, never responding to this goodwill gesture of mine. She continued to work in order to print out my boarding passes, and then finally handed them to me, never at all the entire time looking at me. I told her, “Thank you.” Never once did she respond. My wife and I then walked away. Even my wife commented to me afterward that this woman absolutely never looked at us. I cannot say that this attendant was outright rude. However, she certainly was not at all warm, congenial, nor friendly. Additionally, … After getting on the plane, we then discovered that she had needlessly assigned us seats in the very last row of the plane, these being the seats adjacent to the restroom back wall, thus, unfortunately not at all reclinable. I think that the row number of this last row of seats was 30. [However, I am not sure.] How strangely awkward that we were assigned these uncomfortable row of seats when in fact the row immediately ahead of us, i.e. I think that was row 29, had two vacancies, which could have otherwise easily seated my wife and me. That is, my wife and I could have easily been assigned these more comfortable seats, which would be reclinable, and then row 30 could have otherwise had instead our two vacancies. After our flight departed, and the fasten seatbelt sign was turned off, my wife and I had hoped to “jump seats”, that is, to leave row 30 and instead sit in row 29 to utilize the reclinable seats. However, another couple apparently had the same idea as us. That is, these other two people, for whatever reason, decided to leave their previously assigned seats, and instead, seat themselves in row 29. Thus, my wife and I were stuck with these miserably cramped row 30 seats for the entire 3.5 hour flight. To reiterate, the WestJet rep we originally encountered, knowledgeable of the plane lay-out as it appeared on her computer screen, could have easily assigned us the more comfortable row 29 seats, instead of the non-reclinable row 30 seats.

It was very, very cold extremely uncomfortable almost unbearable I was sitting at the front of the cabin

Was the longest flight I have ever taken to Orlando. Not Westjet’s fault necessarily. There was a traffic issue in Orlando. We sat in the airplane for about 2 hrs before leaving Calgary on a 5 hour flight was just a little long to be stuck in the plane. Once we arrived in Orlando we were stuck in traffic on the ground for another 30min. I guess maybe the flight could be delayed so boarding would have been later so we wouldn’t have to have the discomfort of being on the plane so long.

Airport monitors did not give the gate for our flight returning Detroit to Vancouver Juice served from glass storage containers are a far more healthy alternative for people. And would also minimize the need for recycling plastic or aluminum containers

It was fine. Give us free headphones or allow Bluetooth or something, or an app to watch on your phone. Grow up

The nicest thing I can say about Air Canada is that they are consistent. Consistent delays plagued our trip. We never had one leg of the journey as scheduled.

It would’ve been very helpful to have people directing traffic when we got off the plane at the Toronto airport however, the person who appeared to be having that responsibility was sitting on a chair playing on a cell phone instead of doing their job

A 6 hour flt and only offered water twice the entire flight. A small bag of flavored pretzels was offered as well w/ the first round of beverages. The landing was ‘hot’ but I arrived safely. The plane was nice and new and the seats were roomie. I’m use to warmer more generous hospitality but all and all I’d fly with them again but I’d bring more water and snacks.

Experienced flight cancelations and delays in 5 days. They seem pretty common to AC. Experienced with one of AC's check-in agents at the counter of a big liar. She lied and acted (yes like acting in a movie) that an early flight was fully booked and refused to rebook me, but my flight was delayed two hours so I could not make my connection. Later, I got help at the gate to switch the early flight (Big thanks to that agent). Ater boading, I found the early flight was only 2/3 full meaning there was almost one vacant seat in a 3-person seater, and multiple empty 3-seaters. AC is wired that it is filled with good and bad employees. BTW, AC employees seem never smile, or they don't know how.

My mother, 80years old, had arranged for wheelchair assist to and from the aircraft cabin and in the airport but, no one showed up for her to de-plane. Apart from Air Canada having a reputation of being late for every leg of its flight so nothing was new this time so this time they did worse by not assisting seniors. I guess our whole family is done with this airline

Seating for almost 3 hours in the plan before aircraft takeoff. Very exhausted .

The bathroom did not have hand soap. That is unacceptable.

Moderate size plane, not completely full, easy boarding, some rows with just 2 seats so a couple can have a row to themselves

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.
