Pros: "Thanks for choosing customer safety over profits. I specifically chose Delta because they continue to not sell the middle seats."

Pros: "Thanks for choosing customer safety over profits. I specifically chose Delta because they continue to not sell the middle seats."
Pros: "Good Crew. Landing was very smooth"
Cons: "line to drop bag was so long!! but on the plus side, we were through it in an hour and didn't miss our flight!"
Pros: "non stop flight"
Cons: "Crowded, small plane. No air after people had boarded while fuel was being replenished (dangerous?), sitting at gate for 20minutes. This, after a 2 hour delay. Then a rough landing in Minneapolis- plane brakes sharply and suddenly, shuddered to a taxi rate of speed. simple snacks, not very good."
Pros: "Nothing"
Cons: "Worse experience ever, flight delayed, lost connection, many hours in phone trying to fixed and anyway lost the flight, spent so many time at the airport with the front desk so disappointed"
Cons: "You guys didn't allow me to get in this plane and i missed my flight."
Cons: "When we booked this trip via Kayak, we thought that we were booking on Westjet. Westjet knew nothing about the flight when we tried to check in."
Cons: "Plane had to divert from Salt-Lake City due to a storm. My son 17 years old traveling alone once in Salt-Lake City should have been given priority for an overnight stay instead of sleeping on an airport bench! Dinner + Breakfast vouchers would also have been nice compared to the 15$ food voucher..."
Pros: "Our flight crew were great. Pilots were great too."
Cons: "I missed my connection due to weather in Minneapolis. Was diverted into Milwaukee, but nope we are diverted to Chicago, but wait no we go to Milwaukee. Deboard into a close gate area. Rest rooms were closed. Then once refueling is done get back on and make Minneapolis at 12:15 am. Connection missed"
Pros: "The on board food was amazing, nothing like I’d ever had on a plane before. I was also pleased with the choices for entertainment."
Cons: "The seat was not comfortable in economy. I could not sleep and there were no air vents. Every time I tried to rest my head on the seat in front of me the screen would turn on and get super hot. I wish there was a cover or something you could turn the screen completely off."
Cons: "There was huge issues with our original plane and the lady at the desk was horrible with communication to all the passengers waiting for the flight updates. The one time I finally asked her if there was any updates, after almost 1.5 hours of delay and waiting, she took a very rude and snappy tone."

Great flight, comfort, and staff. Prefer tv in back of seat but watching on phone will do

Pros: "Friendly staff and the support they offered to my mother who needed a wheelchair."
Cons: "I would have liked to have had WestJet internet and entertainment access. It was not offered on our flight from Toronto to Fredericton."
Pros: "It ran on time. The pilot landed the plane without a big jolt. We could board and deplane using 2 exits."
Cons: "Seat space"
Pros: "Rotten stuff cancels out the good doesn't it. Be great if you could take some courses from Stephen Covey as you are missing some skills sets in hospitality. And stop being so cheap with the 3rd rate old old movies!"
Cons: "I did not appreciate having the second row to the last on my 2nd plane coming back - I only had a turn around time of 20 minutes to catch my third Westjet flight. When we asked if the plane would wait for us - your crew just laughed in our faces."
Pros: "Great, friendly crew in this scenic trip across to Victoria. Nice new aircraft operating this route."
Pros: "Efficient crew and reasonable seating"
Cons: "Need more legroom or a device to fold passenger legs for the flight duration..."
Pros: "Crew was good. Seats need to be updated and are confining. I appreciated being able to disembark through front and rear door."
Cons: "More space between the seats."
Pros: "the crew was very polite but the flight was too short to have a meal"
Cons: "delayed embarking"
Cons: "No plugs to charge phone. Though flight was budget class, other airlines does it better when it comes to food."
Pros: "The crew were great! Ingrid was so sweet as soon as I stepped on board !"
Pros: "seat space was great and I was lucky enough to have medium size passenger next to me :-)"
Cons: "Can't really think of anything . . . my expectations were exceeded"
Cons: "The aircraft was old and in need of some work. Nice crew and smooth flight. Just aging equipment."
Pros: "Free open seats"
Cons: "Opd plane. USB ports only in Comfort Plus and above"
Pros: "Preflight announcement on smart bags. Beverage servive god. Snack could be more than 2 cookies."
Cons: "2 flights need more than 2 cookies."
Pros: "Staff was great and service friendly. The flight attendants were truly exceptional."
Pros: "Good flight. Nice staff."
Cons: "Old plane with obviously dated cabin, questionable cleanliness, smaller than average seats. Short flight without beverage service (understandably so)"
Cons: "SeAts too close to each other. The girl next to me kept hitting me with her elbow the whole time."
Cons: "I missed my outbound flight from Chicago to Dallas, and although I called to inform Delta, my return trip was cancelled and i did not find out until the day of my return to Chicago. When I called Delta to figure out what was going on, I was put on hold for two and a half hours. I'm not giving the flight a bad review, since I never got on the plane, but I'm disappointed with the accuracy and care for customers that I've experienced with Delta service. Delta was the first company I've ever flown with when I first started travelling when I was twelve years old, and it is unfortunate that I will probably never book with Delta again."
Pros: "I've done many flights this distance, and just take for granted that there will be entertainment. There wasn't."
Pros: "Unfortunately there were unavoidable delays due to weather but the staff gave regular updates and were very honest. Also, they brought out food and drinks for people bc they knew people wouldn't feel comfortable leaving the gate in case of changes. Staff handled the whole situation very well."
Cons: "the crew verifying that the passengers will use mouth covers during the flight"
Pros: "That it was not to crowded"
Cons: "That their was not much communication when it looked as our flight was not leaving on time"
Cons: "Fue un viaje , sin ningún problema satisfecho sólo con algunos detalles en cuestión de equipaje no se si son los trabajadores de la aerolínea, ya que mis maletas sufrieron varios daños las 4 q traían espero la aerolínea preste más atención en estos detalles ."
Cons: "Plane was delayed for an hour, Mexico city federal police was there and some other teams to ask quest about if someone had approached us to hide something or if they touched us without our permission...it's was weird but this delayed the whole trip."
Pros: "Good service"
Cons: "If you would update your media systems To be able to charge your Devices."
Pros: "The large plane that I was on was great. Comfortable and a smooth ride. Movies were good. Drinks good."
Cons: "Food could be a little better."
Cons: "Was not allowed to board the plane, this causing me to miss my flight."
Cons: "They pushed the first leg of my flight forward 15 hours, but only told me 5 hours before my flight, and they didn't even change the second leg. Was on the phone for an hour trying to get a new flight, and there were very few options. Very stressful."
Pros: "Entertainment on the long haul was good, no entertainment on the fight from Mexico City to La Paz"
Cons: "Multiple delays and gate changes"
Pros: "No complaint at all, I am very satisfied."
Cons: "Gate no printed on boarding passes. I understand that gate no are subuject to change, but at least it would point me on the Wright direction"

The flight was delayed multiple times. I had to buy a new tickets (4 tickets) for my family for a total of $5200 cnd And missed thanks giving with our family. Very very poor and disappointing service.

Room on aircraft was nice main cabin. Interaction with cabin crew could of been nicer....only seen them once

Incompetent crew at the boarding counter. Never flying AA again.

I think the flight attendant and first class was terrific, but whoever had to work in coach where I say didn’t seem happy about it, extremely mediocre service, not friendly, just putting 1 foot in front of the other. Just seemed “over it.”

Pros: "Air Crew was professional and polite - flight was quick and lasted less than 90 minutes in the air, was overall enjoyable"
Cons: "Gate attendant was fairly rude (could be a result of holiday travel stress) - several travelers didn’t speak English fluently, and she would snap at them or roll her eyes they weren’t comprehending instructions. Boarded extremely early (almost an hour) but sat on tarmac for some time - eventually took off about 20 minutes late. Not airlines fault and likely result of holiday backlog Retrieving baggage from plane was biggest issue - use a carry on to but was required to valet bag as opposed to storing overhead. Baggage unloading was late (again, holiday backlog) but no personnel were available to inform passengers of delay, and bags were not in initial cart. Resulted a delay of offloading by roughly 20 minutes. Was ultimately found in the second wave of luggage, and witnessed baggage handlers tossing luggage carelessly onto cart floor. Nothing was damaged but was annoyed at lack of communication and overall disorganization."
Pros: "quiet, comfortable. good food in first class"
Cons: "people with "emotional support animals" should board LAST, not first"
Pros: "The crew was amazing, and the duration of flight time was reasonable"
Cons: "Comfort of the seat, space between seats"
Pros: "No amazing crew, just average. The should airline should have follow through on a specific request, but the airline's computer wipes out such things."
Cons: "Airlines should listen to the requests of the passengers."
Cons: "The booking process. Went through a third party (ka$@k) and at the last minute was transferred to a cheap aggregator I had never heard of. Needless to say customer service was a joke. Plain fraud."
Pros: "Fast boarding, flight relatively smooth, got to my destination pretty quickly as well."
