Airline reviews

Pros: "Comfortable seats with free TV, movies, on time departure"
Cons: "Nothing"

Cons: "Reading lights did not work. Fortunately I could move"

Pros: "Poutin"
Cons: "Higher bagge fees and missed the bus"

Pros: "Everyone super friendly no other complaints"
Cons: "Boarding delay. Also asked last minute before boarding for passport in a new line so had to wait in the back. Consider some of us are crunched for time when we get to destination (rental car before closing, etc)."

Pros: "I checked my baggage with ease.The whole trip was without any inconvience. My daughter in CO made my reservations both ways thru you. I appreciated the great $fare. We will use you again . Thank You, Merry Christmas!"

Cons: "I dint know i needed a chinese visa to travel to shanhai, My flight began on denver then seattle and from seattle i wasnt able to fly to china. I received no help at all, all they did was cancel my booking not received any kind of refund and i got stuck in seattle, i had to buy new tickets to go back to denver after losing my flights and not getting a dime back, this is unacceptable!"

Pros: "Dexter Alaska agent in Seattle helped get me to Portland then Medford a day late."
Cons: "Denver agents seemed not to care at all and said I could not get a hotel voucher in Seattle. Phone agent said I could get a hotel voucher because it was mechanical failure. arrived late late late into Seattle to be told there were no hotels available. I had to be insistant to get agents to make the effort to get me routed. They to me I would have no hotel and then wait until 5 pm the next day to fly to Medford. They gave no food vouchers. I had to pay for a hotel I never slept in in Medford and meals. Seems like Alaska has few flights out of Seattle and Denver and no other partner agreements to help route you. Really horrible bad experience. Not what you expect when you patly $500 plus trip insurance. Pathetic."

Cons: "Nothing at this time."

Pros: "Nothing"

Cons: "Delays layover very poor"

Pros: "X"
Cons: "My daughter missed her first two days back at college because of your cancelled flight. You refused to even attempt to book her on another airline. Very poor customer service."

Pros: "The overall experience was exactly what anyone would expect."
Cons: "The overall experience was exactly what anyone would expect."

Pros: "Inexpensive flight Nice desk people they did give us regular updates and clear expanation of why we were delayed"
Cons: "They took our small carry on bags planeside with a PROMISE to return planeside in Calgary - but didn't - they came through just like a checked back 25 minute wait in Calgary and one of the LAST bags off the flight! Plane was 20 minutes late leaving"

Cons: "Just the oldness of the upolstery."

Pros: "The crew was really friendly and the seats were comfortable with more legroom in coach than most other airlines. I did not partake of food or entertainment, so gave one star because there was no box for "n/a""

Pros: "Great service. Crew was awesome"

Pros: "We left early and arrived early."
Cons: "Vents were weak. Way too warm."

Pros: "Service was good. Not overbooked flight"

Pros: "This is by far the most comfortable Airline I've ever flown! I'm guessing at least six more inches between seats and I could stretch out my legs!"

Pros: "The pilot was very friendly and made sure to point out landmarks as we flew over."
Cons: "The boarding crew in DIA was less than friendly, forcing people to gate-check their carry-ons. She used the claim that the flight was overbooked and 20 people needed to check their bags, then threatened to randomly take them. Meanwhile, 60% of passengers were boarding without roller bags. When I boarded the plane, which was almost full, at least half the overhead bins were empty. I had already gate checked my bag to avoid a confrontation with this pushy lady. Ridiculous!"

Pros: "Friendly"
Cons: "Should show free movies"

Cons: "A quick drink service would have been nice, it was provided on the same flight going the opposite direction"

Cons: "Load the plane from back to front. It makes sense as people leave the plane from front to back"

Pros: "Good"

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."

Pros: "In flight entertainment"
Cons: "Food provided, other than snacks, would be a plus"

Cons: "Delayed 4 hours"

Cons: "Nothing my timing was a bit off it all worked out well"

Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."

Pros: "Comfort + was nice."
Cons: "Had a middle seat between two other men. I was given my seat by the gate. It would have been nice if they placed my more strategically. That might be asking too much but seems reasonable."

Pros: "Nothing spectacular."
Cons: "The headrests won’t stay up. And it’s hot."

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: "Seats are so small. Flight was delayed."

Pros: "Staff from Check in to aircraft very pleasant. Snack choice in Coach impressive."

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"

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

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."

Pros: "Everything was easy and smooth."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Pros: "The staff was polite and snacks were good (healthy options)."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Pros: "Good flight crew"
Cons: "Delayed due to mechanical issues. For 3 hours. No offers for free drink or wi fi. When we finally land we were on the runway for half hour."

Pros: "The staff at the gate were efficient and very friendly, as were the onboard staff."

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Haven't left yet!!!"

Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Pros: "Makes all the difference to have Flight attendants and pilots all wonderful. Gratefully, ~Elana"

Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."

Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "Most comfortable flight I have taken in some time. Spacious seat, power, good entertaiment, attentive flight crew. On time. Not usually a Delta flier, but times and destination made Delta the choice. Turns out a great choice."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Fast and efficient boarding again! Most impressed!"

Pros: "Nothing."
Cons: "Everything"

Cons: "You were out of earphones"

Pros: "We were allowed to board early with my father, who is disabled."
Cons: "Denver airport was a nightmare with my disabled father. We were given a “wheelchair” but no escort through a nightmarish security scene. Airport is terribly designed, lacking clear signage and navigation. TSA was a disaster and no one seemed remotely concerned about my father’s comfort or needs."

Cons: "Less boarding groups"

Pros: "Good, cheap flight that gets the job done. No issues boarding, seats were fine. Cannot comment on most things as I fell asleep almost immediately."
Cons: "Would've been nice to have had an eye mask / blankets on a red eye flight..."

Cons: "I have changed flights. Been delayed 5 times now. And still haven’t left the USA."

Cons: "I researched and called and found a 45L backpack so I could carry on my dive bag. That’s the reason I’m going all the way to Fiji. Not letting me get it in LA I’d also ridiculous."

Cons: "Delay due to equipment failure, were not able to estimate delay"

Pros: "American"

Pros: "Nothing."

Cons: "The crew was a little late"

Pros: "Not using kayak"
Cons: "Kayak booked me the worst itinerary in the history of air travel!"

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: "Nothing!"
Cons: "Almost everything!"

Pros: "Pilot made up time so we made it in early!"

Pros: "The helpful steward"
Cons: "The bumpy ride"

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."

Pros: "On time. Efficient boarding."
Cons: "Stingy with the cookies. Somewhat uncomfortable seating. But what can anyone expect anymore?"

Pros: "Everything"
Cons: "Nothing"

Cons: "Everything"

Cons: "Delayed flight due to crew."

Cons: "Sitting on the runway after landing because the gate is occupied."

Pros: "No surveys"
Cons: "No surveys"

Pros: "El problema es que el vuelo estaba sobrevendido y han cerrado las puertas antes con lo cual me he quedado abajo sin pode abordar. En el aeropuerto de Denver habia solo dos personas en el securty check por lo cual la demora fue involuntaria en mi caso. Cuando estoy haciendo la fila para ingresar al avion (esyando en la misma cola antes de ingresar) me informanque no podre embarcar..(claro ya habia designado mi billete a otras personas. pesima atencion y pesimna experiencia con los empleados de ese vuelo. Denver a Miami"

Pros: "The Denver airport is beautiful"
Cons: "I will never fly AA again - see below"

Pros: "Love the movies!!!"

Pros: "Friendly service"
Cons: "Snacks"

Cons: "American delayed the flight 7 times before cancelling it. They then put me on a flight 7 hours after the initial departure time. That flight was delayed 7 times and then they cancelled it. I wasted 10 hours at the airport."

Cons: "More drinks, snacks"

Pros: "Good legroom,"
Cons: "Older aircraft, tray tables not level, rear washrooms no water, delayed departure"

Cons: "No delays"

Pros: "Nothing"
Cons: "Waiting for a plane to go that wasn’t ready to move, going for 2 rounds of de-icing when the 1st wore off, losing our place in line. Should have waited a little longer at 1st de-icing so we could have left in allotted time period (20 minutes after application). Also fairly certain we left Toronto Airport past the 20 minutes of 2nd de-icing. Which resulted in many passengers missing connection flights (myself included) with as much as a “We are sorry” from Air Canada. I know the weather was an issue, but wasn’t sole cause."

Pros: "On time and new plane"

After a confusing conversation from the officer not understanding that I was not travelling to France ( assumption) I was asked to show evidence I had the right to enter UK !!!! I explained I lived there permanently ; I was then asked why French hate English so much!!! To which I explained only narrow minded people would believe so and that the style of her comment were not appropriate . I explained my children were half French half British and that her comment was offensive ."

Pros: "its was smooth"

Pros: "1 stewardess was great"
Cons: "Flights were delayed. Did not check boarding passes which was scary."

Cons: "Wifi didn’t work after I paid for it"

Cons: "Paid full fare ticket and boarding as a Zone 5."

Pros: "I like the service I receive ."
Cons: "I didn't like the walking to and from the plane."

Pros: "Prompt.. Cleaning"

Cons: "Rather than notify the passengers that our flight would be delayed prior to our arrival at the airport, we waited at the gate for several hours."

Pros: "Calgary air port was very beautiful. I did enjoy movies."

Pros: "Since it was very hard to sleep in the airport due to issues caused by air canada, I slept almost the entire flight."

Pros: "It was a normal flight. Only one hour."
Cons: "Snack options could have been better, only a biscuit."

Pros: "It was smooth and great trip."

Pros: "Liked everything about this new class of service on Air Canada. Seat was comfortable with good recline that didn't interfere with fellow passengers. Food was excellent, entertainment system was well stocked, flight attendants were friendly and high energy. Even got to use lounge and fast-track security lane at Heathrow."
Cons: "Zero complaints."

Cons: "Plane was too small with extra small overhead bin. We were asked to keep Cabin Luggage beneath our seats even though it fits the prescribe dimension. Return flight was first late then was told that the Restroom inside the plane is not working which is weird (atleast i never experienced this before)."

Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"

Cons: "See above."

Pros: "The seating on the airbus 319 in main cabin is very cramped. Prefer Westjet 737. Will use them in future."

Cons: "Hey there good Air Canada folks. I'm a full-time, working, touring musician. I enjoy flying your airline overall, but touring with an acoustic guitar and/or a banjo is constantly stressful. There are clear guidelines about your policies for musical instruments posted on your website, yet your employees never seem to know them. Please have something posted for them at the gates, so I don't have to convince them EVERY TIME that it's okay for me to carry on my instrument in a soft case. A side note: Since airlines started charging for baggage, people are desperate to carry on as much as possible. This means there is always a struggle now against people with a bunch of clothing and personal items in their rolling luggage, to fit the instrument that is my LIVELIHOOD on the plane. Please find a way to make touring with Air Canada easier for musicians. At least return to gate check policies."

Pros: "The landing of the aircraft was second to none when we landed in Calgary."
Cons: "The seats we were sitting in were uncomfortable. There seemed to be a ridge near the back of the seat cushion and it was very uncomfortable for the entire trip."

Cons: "My seat partner had a dog with her. I like dogs but it was more of a irritant and distraction, didn't seem that nice for the dog either. What happened to the pretzel/nut snacks?"

Cons: "See the above review"

Pros: "On-time departure and courteous crew. Smooth flying on this leg of our trip."
Cons: "I don't have any major complaints about this flight."

Cons: "Flight Attendant was REALLY late. We had to delay boarding to wait for her. 15 minutes. then it took longer to wait for gate check -- green tag bag - than if I had checked the bag. when we finally got the gate check bags and headed through customs the checked bags were all on the carousel. And I have Nexus. So Customs was 3 minutes. NOT a good process. Figure it out YYC international terminal!!!"

Pros: "Amazing plane with great features! Incredible staff!"
Cons: "Bathrooms should be bigger"

Cons: "Delayed and got downgraded"

Cons: "Not like Air Canada ... I can tell the staff are tired of their jobs. Entertainment you needed to pay for. Really bare bones"

Pros: "Co passengers friendliness"
Cons: "The tiny cup with more ice than refreshment. Small bottles of water would be great - less likely to spill over in bad weather and thirst would also be quenched. Lack of luggage space for those of us with the correct allowance hand luggage instead of all the extra large pieces because people don't want to go to baggage claims or pay for baggage. Truly their suitcase not paid for is the same as mine paid for. Difference is the inconvenience of having to keep my hand luggage at my feet because of the larger pieces filled by passengers in group 1, 2, and 3 over my designated seat area."

Pros: "There was a lot of space and a quick departure."
Cons: "When we got to LA event though we were early we had to wait. I know its not the airlines fault but it sucked."

Cons: "Nothing"

Pros: "Nothing"

Pros: "The kindness of the staff."
Cons: "Having to go back to Denver because of a storm-in Omaha."

Pros: "We arrived safely along with our baggage."
Cons: "Major weather issues so delayed boarding and flight. That's understandable, but poor, often rude, gate operations. Often no, inaccurate, or misleading information. They seemed confused, as if this were the first time event."

Pros: "Love the free tv/movies with the United App. That was great!"

Cons: "Delayed 3 times. United is known for delays, everyone jokes about United delays!"

Pros: "crew personable"
Cons: "Wifi didn't work"

Cons: "Their plane broke down, no assigned gates ,"

Pros: "Everything went as planned"

Cons: "No compliementary snack. Customers that pay to check their bags should get a snack included with the cost of checking a bag."

Pros: "Plane was fine, but very cramped."
Cons: "Seat was very cramped. Overhead bins are too small and had to gate check my carryon."

Pros: "nothing"
Cons: "t was delayed without informing me i stay in airport 6hours"

Pros: "Met a cute girl!"

Pros: "United is predictably competent and professional."
Cons: "The seat pitch is very close in coach. Being already 3 by 3 on the A320, sitting at such a close pitch is uncomfortable."

Pros: "Small plane completely booked."

Pros: "Smooth with courteous staff"

Pros: "I recomend it..."
Cons: "No complementary food!!!"

Pros: "Everything was very good!!!"
