Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

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

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

I had planned to watch the Westjet entertainment for the entire flight however, because the seat mounted outlets in our row did not work.

Not a bad flight but our priority tagged luggage was the very last to come down the carousel.

I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

I really do not like the basic in basic economy.

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

There were delays on both ends. It made it less than excellent. This plane was great though

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

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.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

Terrible quality wifi and they charge a lot for it. They nickel and dime you for everything.

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!

I don’t know if there were any snacks served on the 5 hour flight. I might have been napping when the attendants came around. But I usually wake up when they do.

Food offerings need to be more plentiful and beverages need to be more healthy.
