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: "On time"

Pros: "Friendly staff"

Pros: "The crew was very nice"
Cons: "There wasn't any good offered without paying"

Cons: "I liked everything. No complaints"

Cons: "No actual meal given to passengers unless you paid for it"

Pros: "Friendly people."

Pros: "The flight attendants were awesome! Very helpful and attentive.`"
Cons: "I was told that I would have internet onboard the flight. I was very much looking forward to that. When time came to connect, all I got was inflight onboard local network. No texting, no watching of football games. I would not complain had I been told up front there was no internet access."

Pros: "Seat room"

Cons: "Gate at Seattle airport was crowded. Not airlines' fault but it was tough to navigate Seattle airport."

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."

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."

Cons: "I wasn't able to check in early, and received an error that perhaps I didn't pay in time when I bought this months in advance. Fortunately I called early to get it sorted, but I wonder if I would have been left at the gate due to Alaska's error."

Cons: "I paid for a window seat and the seat next to it. I ended up with two aisle seats. This meant my grand-daughter and I were not sitting next to each other. NOT ACCEPTABLE"

Pros: "On board service was terrific."
Cons: "Flight was over an hour delayed and then there was no gate available upon arrival!"

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

Pros: "Plane was new 737-800 on first leg of trip. Flight Attendants (FAs) were very attentive, courteous and helpful. NOTE: I have not flown first class since the TWA days so anything above coach service is impressive. Second leg was just as impressive but plane was same model but slightly older. Special thanks and kudos to FAs Elinor and Rita! Hey we're great as was the entire crew including the ticket counter staff and everyone associated with the experience."
Cons: "The portable tablet had a few minor issues but did provide a source of entertainment options."

Pros: "I had a connecting flight in Seattle and the gates were conveniently right next to each other which was great. The crew was awesome very friendly & helpful!"
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""
Cons: "Arriving 20 minutes late to Seattle, which was the fault of the airport, not Alaska Airlines, but it still affects my rating of the trip"

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

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!"

Cons: "My seat was uncomfortable with the cushion being hard"

Pros: "Seats have good legroom"
Cons: "I was discriminated against for having a service dog without all the records and forced to stuff a 5 month old puppy in a tiny carrier or be cancelled off the flight. I guess pro is they let me on but is this really necessary in these times? She didn’t let out a peep even though she was in the equivalent of a large man in a small seat. I’m never flying JetBlue again. Thanks but everyone else can use my travel money."

Cons: "The tray table was very dirty when I put it down. I brought my own wipes but that was pretty bad."

Cons: "Loved the sleep pack, you guys rock!"

Pros: "The crew and pilot were awesome! Very friendly! Nodding was pretty quick."
Cons: "It was an older plane. WiFi Didn’t work. But not a huge deal. It would be nice if they ask you to check at the gate due to overhead space if they could have those bags come out first from the baggage claim."

Pros: "Crew was nice, and pilot was helpful and got us there early."
Cons: "My screen for movies didn’t work, and the level of comfort was... almost none. I would’ve upgraded to more room, but for $55? When I’m already checking a bag for $30? On top of flight price? Too high, expected JetBlue to not jam pack all the seats like the exit aisle.... for long flights, not again."

Pros: "Everything"
Cons: "Nothing"

Cons: "Maintain their planes, we were delayed more than 3 hours and this was such a poor way to handle it."

Pros: "The crew was really professional and I liked a lot of leg space."

Pros: "TAP Portugal was great."

Cons: "Update delays earlier. There was no plane at the gate. We knew it would be delayed especially with the weather in Denver. Honesty earlier."

Pros: "The crew members were polite and courteous, and the flight was ahead of schedule in arriving."
Cons: "The cabin could have been a bit cleaner."

Pros: "JetBlue is by far the best airline I’ve flown. Love them!"

Pros: "Loved it."

Pros: "Seat was spacious and comfortable"
Cons: "The flight was nearly an hour delayed and the only way to talk to someone until right before the plane arrived was to go back to the ticket counter (and go back through security)."

Pros: "Appreciated the second round of water"

Pros: "JetBlue provided ear plugs and a sleep mask. I honestly slept most of the trip. Red eyes are awful, but JetBlue made it bearable."
Cons: "Couldn't turn brightness down on headrest monitor. Both of the other screens were able to crank brightness down to off"

Pros: "Comfortable seats, snacks, good price, nice & helpful were all the flight attendants and persons at the counter. Flight was 20 min late arriving at Denver, but our pilot got us to Boston on time-much appreciated. Free WiFi was great.seats and the next plane (my plane)o not"
Cons: "Could have taken an earlier flight from Boston to DCA, but there was $75 change fee even though the plane had lots of seats. But I do not hold this against JetBlue."

Pros: "The crew were very nice and respectable and did their job as professionals! We landed on time and the disembarkation was smooth, with no problems!"
Cons: "The person on my right (I was in the middle), wasn't very considerate! He hogged both arm rest, had one of his feet on a personal bag (I had in front of me) and was just plan rude and impolite as a passenger!"

Pros: "Arrived 20 minutes early"

Pros: "Extra room seat was great. Crew was nice. Boarding was easy. Lots of leg room. Appreciate mask and overnight kit for sure."
Cons: "Flight was very cold."

Pros: "New plan was clean, good staff, pilot did great landing in storm"

Pros: "Liked eye mask"
Cons: "Couldn’t recline seat"

Pros: "The crew was awesome. Christina went above and beyond"
Cons: "Every flight by JetBlue out of Denver to Boston has had a problem. Been canceled and or delayed Everytime. This time was delayed 30 mins then another 30 mins then the delay was retracted via email but when I arrived to the airport the delay was still in effect. Ended up being delayed 20 mins but it was chaotic and frustrating with no apologies"

Pros: "No food served only soft drinks and chips"

Pros: "The flight and crew were totally fine. I slept the whole time."
Cons: "There was not a single JetBlue employee at the Denver airport until exactly 2 hours before the flight. There were many passengers (upwards of 20 and many with small children) waiting around to check their bags and unable to access the food/bathroom/go through security. Everyone was confused and upset. While I understand that there are no flights for several hours prior to the late-night flight I was on, that does not mean that there is no need for an employee presence. Many people arrived multiple hours early because the most common destinations for Denver travelers are the mountain ski towns and the last departures of the shuttles that run from the mountains to the airport leave at 3:00pm. Therefore a large number of passengers arrive by 6:00pm for midnight flights and are left waiting in the check-in area until 10:00pm. The situation was made worse by the poor communication--there were signs saying that checkin was open only from 8:00am-11:00am, which left everyone very confused, given that we were on evening flights. There were many angry people sitting on the floor around the JetBlue counter."

Cons: "Flight was late taking off from Denver."

Pros: "everything"
Cons: "nothing"

Pros: "The staff was super friendly and lively even though it was midnight. The flight was so smooth I slept through the landing"

Pros: "On the overnight we got eye masks and ear plugs and pleasant lighting. It was very nice. Every one of the staff members were nice and accommodating."

Cons: "nothing"

Pros: "Staff, seat size"
Cons: "It was brutally hot, not just for myself but the whole row. The air vents did not work."

Pros: "Comfortable seats. For cheap seats."

Pros: "Ghj"

Pros: "My red eye flight was quick once we took off."
Cons: "We were delayed, then undelayed. There always seems to be some type of hickup with my JetBlue flights in and out of JFK. The flight attendant that boarded us made numerous mistakes when calling up particular rows, then yelled at the passengers to move back and get out of the way. Once we landed, they weren't ready for us at the gate so we had to sit on the plane for around 10-15 minutes until they found staff to receive us."

Pros: "Everyone was friendly and very helpful"

Pros: "Absolute BS"

Pros: "Always a fan of JetBlue - boarding process, flight crew, snacks, wifi, TVs. Great experience."

Cons: "No complaints. One of the flight attendants seemed kind of annoyed, and put off by any request anybody made."

Pros: "Boarding seemed to be pretty efficient, especially compared to my most recent experiences on American. Flight was smooth (of course, airline doesn't have much to do with that). Got to my destination along with my luggage. Did not feel cramped on the plane and I was in a regular seat. Did not feel like I had to spend through the nose to just have a passable experience."
Cons: "Flight was almost 2 hours delayed. Plane felt a little shabby. Sometimes I found it hard to understand the flight attendant who did most of the announcements - she had an accent, which would have been fine, except that she either spoke too fast, or was mumbling. All that together, made it hard to understand her. Pilots never spoke to us. Not once."

Cons: "40 minute flight delay and my luggage was lost/stolen."

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

Cons: "100% as always.. delta has never disappointed! Keep up the good work guys"

Cons: "Delta.... they’rrrrrr Grrrreaaate!"

Pros: "The crews were super accommodating and my seat was so comfortable I actually feel asleep which is something I have never done on a plane before."

Cons: "Everything was really nice. The snacks were good. I don’t know if there are excellent t snacks but very good."

Pros: "Crew was friendly and efficient."

Pros: "Good"

Pros: "I think Delta is upping its game, and I’m pleased to see that. Almonds for snacks, phone info about the state of your checked bags—good stuff."
Cons: "Of course the seat was not “super comfortable,” but whe you pick Economy, you know that."

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: "Quick flight...ahead of schedule"
Cons: "Cheese It’s are boring...miss the snack mix"

Pros: "The service, on time, employees very nice."

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

Cons: "Choice of healthier snack"

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."

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"

Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."

Pros: "Check in Denver super helpful Gate staff hustled to turn around flight Flight crew excellent"
Cons: "Flight delayed, almost missed international connections"

Pros: "Boarding, friendliness of staff"

Pros: "Everything was easy and smooth."

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

Pros: "The fact that there was a screen for movie selections and a charging port for my phone and the flight attendants were super nice"

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: "No issues boarding as a group of 6, including one child. We all had at least a personal item and/or a carry-on to stow. The flight was easy, comfortable, and the free movies were current and definitely helped pass the time."
Cons: "We were seated right behind the delta comfort+ and saw the special snacks they got. Being teased by that is not a huge deal, just a little disappointed by the regular snack selection, the snack mix was definitely subpar."

Pros: "Getting home in one piece"
Cons: "Why do airlines schedule 2 flights for the exact same time in the exact same gate? Just to watch passengers squeeze in like cattle??"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "The crew forgot to turn the heater on in -3°F creating a situation where the lavatory water lines froze. This caused a two hour delay which made me miss the second leg. Because I missed the second leg I was put on the very last flight out of ATL and got to spend Xmas eve in the airport."

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

Pros: "What a city.. Unique for hell sure..."

Pros: "Newer plane with movies."

Pros: "Great,I loved it!"

Pros: "Food, crew, boarding"
Cons: "I had a screen in front of me that did not work. It was annoying. Fix it."

Cons: "I fly Delta quite often, and am usually pleased with their service, but the morning of June 23 was terrible. I got to the airport in Denver at 5:30 am for a 7:30 am flight to Atlanta, and the line to check a bag was about 40 people long. I waited 55minutes to check my bag, as they kept moving the ski priority people, and people in danger of missing their flight, to the head of the line. There were obviously not enough Delta workers on staff to process all the flights at that time."

Pros: "The moviea"
Cons: "The time of night"

Pros: "Everything else fine."
Cons: "Made me check my bag - even though ther was plenty of overhead bin space."

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "First we had a mechanical after boarding. I was rerouted through Atlanta. That flight is now delayed by 2hours. I then had to reroute to West Palm Beach instead of Ft Lauderdale. I will leave 9 hours after my original flight time and arrive 8 hours later. Just ridiculous"
Cons: "See above"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "Entertainment options"

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Cons: "Seats too close - I'm not that tall and my knees were jammed against the seat in front of me."

Cons: "Overbooked and crowded, on a Sunday."

Cons: "Everything was dandy!"

Cons: "Crew was not attentive. Temperature was cold."

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: "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"

Cons: "Checked baggage untimely, causing me to miss the train"

Cons: "Boarding crew was not very polite. You can get the same message across with out being rude. Just not necessary."

Cons: "Less boarding groups"

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: "They have very long and annoying credit card announcements"

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

Pros: "Nothing."

Pros: "Short flight"
Cons: "It was so ht on the aircraft, Almost no aircirculation"

Cons: "Nothing"

Pros: "Nothing"
Cons: "Everything"

Cons: "No surveys"

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

Cons: "I had a severe back injury in Denver and they were unable to move my flight up a day to get home and see a doctor.

Cons: "Once again I had to see an agent to get a seat assignment on a 30 min layover. I though I got an upgraded seat but instead they gave me the wrong boarding pass. Same last name different first name so I had to wait till it got figured out and then be the last person to board so once again I couldn't find a place for my bag. Probably one of the worse flying experience I've had in a while"

For health reasons I did not want the trip to baggage and I did not want to risk my bag being lost. I drive 3 hrs o the airport and I did not want to drive back or wait 3 days for a lost bag to be sent to me as I have before. The person at the gate was rude when I said you won't lose my luggage will you? he said Probably. I said really, and he said well you did ask."

Cons: "Nothing"

Pros: "Peaceful"
