Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

It was beautiful easy and smooth experience. Thank you. Will definitely get Delta for my next travel.

Great!! I haven’t had a bad experience with them.

Ran out of my choice of main course in BClass. Kind of weird combo for substitute.

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

Leg room was lacking. Legs crammed into seat in front.

Flight was delayed but reasonable notice and communication was always there for the passengers.

Despite travelling ultra basic for the first time due to such increased rates we both managed with one bag each. Even boarding last wasn’t SO bad.

Flight was early. That’s the only positive I can share. I paid for wifi on the flight and it didn’t allow me to use any streaming services so it was a waste of $20. West Jet also lost my ski equipment on my way to a ski vacation. They told me it would be delivered to the hotel as soon as it arrived at the airport. It was never delivered. I had to pick it up at the airport on my way home. I am completely disgusted with my experience on west jet

I was seated near a "stinky" person. That's not the fault of Westjet🙁😶‍🌫️

my carry-on bag was delayed and I did not receive it until the day of my return at the airport. This delay caused me significant inconvenience, as I did not have access to my personal belongings for the duration of my trip. I had expected to rely on my carry-on items, and being without them negatively impacted my travel experience.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

Westjet has a terrible boarding crew. I had a zone 3 pass and my wife and kids had zone 9 as we purchased tickets separately. After scanning our boarding passes, the boarding Filipino lady rudely says that my family has zone 9 passes. I said I have 3 and wanted to board as a family and she started a rant that they have 9 and they were small kids to board with me. I told her that I am not going to separate family because of this and what she said didn’t make sense. It’s a shame to Westjet if they have such policy. It’s a shame to the WestJet employee to start this rant after the passes were scanned. Westjet has to train people to speak politely and not with rude demanding tone. If that’s Westjet policy, I will pick a different airline next time. Westjet is not the only one out there.

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

Sat on the tarmac for 1.5 hours after landing. The flight was OK, after that, not so much

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

The luggage was completely damaged. It was ripped at the corner and the lock was stuck. We had to rip it open.

Awful. We had an 8 hour mechanical delay- no vouchers and no kind/courtesy/professional representatives in the entire airport. Not only was it a terrible experience for both my 7 year old and myself, I still have not heard back from American about how they’re going to correct it- I’ve sent 2 or 3 emails about our experience- which was just awful. Not to mention according to national traveling laws, we should be reimbursed… but of course they’re not responding.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

The flight was delayed and we were told the airplane is on its way to the gate from the hangar. We were told this for 2 hours and the flight was continually delayed in ~30 minute increments. Then we ended up having a new airplane. The issue wasn’t clearly communicated and it left everyone feeling confused about when we would actually be leaving. Whenever they communicated a new boarding time it felt arbitrary and random. The boarding process was a mess and disorganized, which made it last longer than necessary. Landing was rough. Seats were uncomfortable.

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

As previously mentioned in last review , seats are small and uncomfortable, and baggage fees are high!

We got home a day late because of mechanical problems and that they wouldn’t put us on available other flights.

The seats have no leg room and my seat head rest was broken

Flights delayed over 4 hours with no compensation. No agents at counters to assist with re-booking.

Well organized check in and boarding. Aircraft had comfortable seats and lots of leg space, both ground staff and crew members were nice.

We culd not check in ovr the inrnt since e did not have the unied airlns boing efence Tis is alays a issue when boing coe shae flits witstr allince

The flight was good they didn’t take off on schedule

It was a pleasant flight all around. The staff were courteous and it went by quickly. The pilot was great and the plane, well, I just couldn't do it without them. Blessed to arrive safely, thank you.
