Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"
Pros: "The seat was comfortable and the plane wasn’t over booked."
Cons: "I didn’t like that we took off an hour late."
Pros: "Comfortable seats"
Cons: "Delayed, may of been beyond the pilots control. Scrambled seating arrangements."
Pros: "Even though there was no TV screen in the headrest, we were all provided with IPads to view. The controls on the IPad were quicker than the in headset TV's. The seats were comfortable and we all received a flight packet that included a toothbrush, eye shades, ear plugs and a pair of socks for our comfort! Blankets and pillows were in our seats when we arrived."
Cons: "I missed being able to see our flight path. On a long flight it's difficult to keep track of where we are and now much longer we will be in the air without the flight tracker. My baggage was misplaced, so I was delayed by needing to fill out forms for lost luggage. Thankfully, it was located before I reached my connecting flight."
Pros: "The flight attendants were friendly and professional and took time for a little personal conversation."
Pros: "Management as well as staff nice...First trip with Alaska and made my trip nice .. Got a good deal price too."
Cons: "Nothing."
Pros: "Plane very warm, not comfortable. Only one pass for beverage service."
Cons: "Very warm air vents did not work."
Cons: "i wish Alaska would fly straight to Denver from Montana. I fly from Montana to Denver a lot and it ends up being a whole day of travel instead of a couple hour flight."
Pros: "The plane had far more leg room than typical airlines which was a pleasant surprise. It was newer than most, the flight attendants were polite and accommodating and the ride was smooth!"
Cons: "No complaints"
Pros: "It was a short flight. The overhead bins weren't overloaded."
Cons: "Boarding was a hassle. The flight was too crowded. The food was non-existent.. Seats were uncomfortable."
Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"
Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
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: "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."
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The flight attendants were amazing. 12 people had a connecting flight and they brought a shuttle bus. You dont see that kind of service any more 10 stars for that"
Cons: "Super small plane."
Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."
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."

Delayed because of late incoming , but once loaded, was a great flight.

Long delay die to pet mix up. Also bags took forever to get to carousel

Pros: "Crew did the best they could under the conditions"
Cons: "There was a broken toilet that was very loud and created long line ups because economy only had use of the 1 bathroom while the first class had 2 bathrooms for so few people"
Cons: "More than an hour late departing. Added to that it was almost an hour before luggage appeared. Not West Jet’s fault but it made us even later resulting in some of our long drive of our drive to Grand Canyon being in the dark."
Pros: "Head flight attendant who gave all the message was not friendly, rushed through her messages like she was not enjoying herself at her job."
Cons: "We left the gate late by 20 minutes only to stand in line with 8 or so other planes waiting to taxi to runway for take off. No explanation was given. However pilot did make up 30 minutes of that time in the air."
Cons: "No Food to buy available on board. We thought we could buy something. The coffee was good."
Cons: "The food could have been better. I don’t mind paying but some nicer, healthier choices would have been nice. It is airplane food so no real surprise. :)"
Pros: "Excellent pre Boarding service and announcements; reasonably comfortable seats; great landing;"
Cons: "There are never gluten free options in the snacks; there were no entertainment systems on the plane - that's not important to me but perhaps it is to others."
Pros: "Crew were fairly attentive, have experienced better. Liked the Canadian entertainment options, even if very limited."
Cons: "Seats were okay, the plane is really showing it's age. Movie selection was very limited, and very dated."
Pros: "Good boarding. The info I was given thru Kayak seemed to indicate my cheap ticket did not include any drinks or snacks, so I was prepared with my own for this long flight. So cookies/pretzels and juice, coffee, etc. were a pleasant surprise, Also the middle seat was empty."
Cons: "Clearer info on what was included in my ticket."
Pros: "Nothing. There were no Covid-19 measures in place and no social distancing. Unsafe. Crew without masks."
Cons: "Is it that hard to follow Covid-19 measures? The flight was full and people sitting shoulder to shoulder."
Pros: "The flight was on time. Excellent in-flight device. I would definitely recommend Aero Mexico to any potential patrons."
Cons: "They kept taking my carry-on luggage, and checking it in, even though it met the standards of being a carry-on luggage, including the weight, size, and the plane was not full. I felt discriminated against, and did not appreciate having to take risk and time to have to wait and pick up my carry-on at a baggage claim in both round trip flights."
Pros: "Nothing. Didn’t get to take the trip and had no customer service to assist in any respect to have a voucher or credit or anything. Garbage"
Cons: "Everything. Coronavirus lock down sucks, but some sort of accountability would be nice for having my money simply stolen."
Pros: "The crew was great except the pilot."
Cons: "The worst landing I have ever experienced. We hit the ground very hard, it was jarring."
Pros: "The fact that I made it to my destination on time was good. Flight attendants were very professional and attractive, pleasant to speak with."
Cons: "It was a couple days ago and I had had a long previous day so I don’t recall anything that was so out of place that really requires any improvement."
Cons: "Our flight from Cancun to Tijuana would not let us on the plane because we went to get something to eat after we had checked in and the Stuart at the gate said we were too late to board when we still had 35 minutes before the plane was scheduled to take off"
Pros: "the service was great! lots of great movie options"
Cons: "VERY hard to hear important details from the captain. Nothing could be heard. Also, the gate numbers kept changing CONSTANTLY. I was given one then like 4 more at Mexico City. Lastly, our flight was delayed and even after everyone boarded it took about 40 minutes for the plane to take off."
Pros: "FA in 1st was awesome"
Cons: "food presentation was nice but the pasta dish was like rubber and barely warm"
Cons: "How would you be able to up grade for a better seat"
