Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Read more about Delta
Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."
Pros: "This is a delayed flight after having my flight to the previous night delayed to the extent that I could not take it and make my connecting flight out of Minneapolis."
Cons: "This is a delayed flight after having my flight to the previous night delayed to the extent that I could not take it and make my connecting flight out of Minneapolis."
Pros: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."
Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."
Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."
Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"
Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."
Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."
Cons: "The landing was pretty tough and we took off almost a half hour late."
Pros: "The staff was polite and snacks were good (healthy options)."
Cons: "Nothing was terrible, but due to the short flights I assume they don’t worry about having planes with entertainment available."

Flight booked from Montreal via Toronto to Huatulco. Toronto to Huatulco flight was cancelled, lost one day of vacation in Toronto waiting for next flight. Flight from Huatulco to Toronto delayed, missed connection to Montreal. Westjet counter closed. No hotel, no connection flight for 4 days to Montreal to finish the journey. I shall go to Small Claims Court to get compensation for all these troubles. Westjet never again.

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."
Cons: "My other WestJet flights let me have access to wifi via the WestJet app and the entertainment console. I was disappointed to not have access on this flight."
Pros: "On-time flight, satisfactory crew."
Cons: "Seat felt cramped (not helped by overweight guy next to me), plane was warm with very mediocre airflow, window seat was missing window."
Pros: "Consistencies on bagage claim info, and changes in boarding gates."
Cons: "Inconsistencies, on my way back to montreal from the philippines, i was informed that baggage would be claimed directly to final port of destination but didnt, when i arrived at toronto i had to take my bagage and drop it off again, although my next flight would be with west jet airlines, korean air was not able to communicate well with their airline partners as to bagage claim and changes in boarding gates."
Pros: "The air hostess were very nice and dis their job well. I complained about the baording lady who got us boarded on to flight and they apologized. They saw the whole incident when the lady came on the flight but they did know know her name when I asked later. That served well with smiles and jokes"
Cons: "I went on the flight running through security to make it on time for my flight. Unfortunately security was too long and took a while. I forgot my hand luggage when I grabbed my other bag. I tempted to go out and get it after I boarded. She spoked high toned voice instructing me to go back on flight. I went back and i did... she brought my bag from security I was grateful until she spoked loud in the mid section of the plane to me sarcastically and rudely "so you left a whole bag" and walked out after placing it up. I was sitting way back and people saw it all. I felt she embarrassed and very bad and i think customers should got be treated that way."
Pros: "The flight was on time."
Cons: "That I had to pay $30 for one checked bag, would have thought the first one was free!"
Pros: "Great flight, quick, efficient, good service & on time."
Cons: "In flight entertainment was unavailable- solely GPS map was accessible on in flight entertainment."
Cons: "Late, late, late. No window, and prisoner in my seat!"
Pros: "Kayak and the WestJet app are a great combination. Overall the trip was excellent. No food (just a light snack from Toornto to Montreal) and no entertainment, but the flight was pleasant."
Cons: "No food, no usb for charging."
Cons: "The crew, could have paid attention to their guest. It was terrible, this flight reminds me how much I enjoy flying Southwest, instead of American Airlines. The only reason that I flew this airline, was because It was free with Points"
Cons: "I never made it... I had a trip interruption and got stuck in Chicago and would of had to wait another full 24hrs to take the flight to Denver. tired and nauseated after being all day at the airport that at midnight, i knew that I couldn't hold off till the next evening, took the next flight back."
Cons: "The flight was delayed which caused us to miss our flight in London our family was delayed for 12 hours"
Pros: "The crew is good and attention"
Cons: "They need to prevent to inconvenience or un conformity towards to the people or customers becouse they don't give information in time"
Cons: "Delay due to equipment failure, were not able to estimate delay"
Pros: "Older style cabin, but still a comfortable flight. Crew was friendly."
Pros: "Great service, friendly staff. Plenty of in-flight entertainment options"
Cons: "N/A"
Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."
Pros: "seat"
Cons: "Staff seemed exhausted. American has no customer service phone to explain to customers what is going on. Bad experience all together."
Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."

During boarding, the crew told us there was new room left in the overhead bins, so carry-ons that didn't fit under the seat needed to be checked. Barely half the passengers had boarded at that point. I left my carry-on case outside the plane for checking. When I got on the plane, I saw there was still plenty of space in the overheads, so I went back and got my case. Another complaint, there was literally no entertainment of any sort on this plane. No screens for movies, no headphone jacks for music, nothing. I could understand if it was a an hour-long commuter flight, but it was 3+ hours.

Flight was cancelled on the departure day. We had to drive an extra 250 km to make it to another flight that was also cancelled. Finally booked on another flight that was also delayed 1h30...weather was fine on all flight. Every delay because of technical issues. Horrible experience.

More delays and almost got diverted to another city. Didn't get set up for text notifications.

4 hour delay that caused me to miss my connection. Couldn't get changed to another flight until arrival. Instructions for checking in for the first flight were wrong. There is no Air Canada counter in OKC to check in with.

Air Canada is a reputable airline, dedicated to supporting customers.

Cons: "There were several announcements to download the Air Canada app in order to access in flight entertainment. They must have been 5-6 announcements about this. WiFi access was to start after take off in order to use the app. but was never available."
Cons: "Food had little taste. Movies were not that current and selection was sparse"
Pros: "It was basically a United flight instead of Air Canada. Had usuall good quality United service"
Cons: "No problems"
Pros: "Cabin crew were terrific!"
Cons: "The unfortunate delay of our flight. And the entertainment systems seems to be getting old. What I mean is that it is by todays standard very very slow to switch between menus etc. And in some cases did not display all the menu content."
Pros: "very nice crew"
Cons: "plane was too small and there was 1.5 hour delay departing"
Pros: "The crew was great and the landing into Denver was very smooth."
Pros: "The people were nice and helpful. And the aircraft did not feel cramped. I again did not use the entertainment or anything like that."
Pros: "Seats were pretty comfortable"
Cons: "In-flight entertainment depended on the Wi-Fi working. It did not work the whole flight."
Pros: "The app promoted me to check in on my phone and would not allow me to check in. So I assumed the time on the ticket would be my boarding time. I was late for my flight."
Pros: "I purchased a ticket for my 18 year old dog $ 125.00 each way to fly with me to Kalispell and back. She is so old that she can not SEE, HEAR, or BARK any longer. I understood she needed to be under the seat for take off and landing but I was told by the ticket agent and flight attendants on my first flight that she could sit on my lap during the flight. Everything was great on the way there. On the returning flight,.... the flight attendant was so RUDE to me. She saw that after we were airborne and at a steady altitude, I brought my dog "Kacey" up into my lap. She immediately raised her voice and stated the dog needed to remain on the ground. I politely explained her condition BUT she refused to listen to anything. I put my poor old dog back under the seat. After approx 20 min I could hear her patting very loud. I lifted her again and asked a different flight attendant for some water. She was very hot on the floor. Or course, the flight attendant saw my little chihuahua drinking the water and said that after she drinks a little more, she must remain under the seat. By now, my husband is getting annoyed. He tried explaining to the flight attendant the medical needs that my dog has " she's on protein shakes" which were approved their security. and how fragile she is. She can't BARK, SEE, or HEAR. Yes, we will be putting her down soon but we took her to Montana for my daughter to say her GOODBYES!! Sorry to say, but that flight attendant has turned me away from UNITED AIR LINES forever. Feel free to call me 352-804-8344. You may send this to UNITED AIRLINES too!! Thanks Karen Hope"
Pros: "I enjoyed my interaction with the other passengers."
Cons: "Several delays compounded to make trip a lot longer and far less comfortable than it needed to be."
Cons: "The air did not work on this plane and it was hot and uncomfortable! Usually once you take off the plane cools down. We sat on runway for 15 minutes due to weather(which the airline cannot control). However once we took off the air still did not work and the plane was uncomfortably warm with little air movement."
Pros: "There was plenty of space on the plane even tho it was completely full"
Cons: "I missed my flight due to a nonsense delay from Charlotte. Arrived at the gate 1 minute after scheduled take off and the plane was gone. Not even an attempt to waiting as I ran, 5 months pregnant, through the airport. I was rebooked to arrive in Las Vegas at midnight. 12 hours after the original time. I bought a flight from Southwest. I will never fly united again"
Pros: "The crew was excellent"
Cons: "IF A PASSENGER CANT FIT IN ONE SEAT MAKE THEM BUY A SECOND. I SPENT 2 HOURS WITH SHREK SITTING ON TOP OF ME"
