Airline reviews
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
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."
Cons: "No AC for an hour before takeoff - very uncomfortable. Audio for tv did not work."
Cons: "More leg room and seat width. I don’t like having other passengers pressed against me."
Pros: "Love the fact that the head rests move to support your head better."
Cons: "No meal option and my video screen volume did not work"
Pros: "Crew was nice and welcoming"
Cons: "Well, if our plane had been leaving on time it would've been superb."
Pros: "Jeff was our flight attendant in first class. He is an excellent flight attendant. He has an amazing attitude and his manner made us feel as if we had been friends with him for years."
Cons: "Passengers who pay retail for first class on domestic flights should get access to the Delta lounges even without the AE card. Other airlines do this, and we have come to expect it."
Pros: "I like American Airlines in general."
Cons: "I noticed there was a disagreement/issue between a passenger and the aircrew, but it was handled quickly when the passenger just left. I understand there are some issues sometimes, but I noticed attitude from three of the flight attendants during the flight. There were three teens in the back that kept rambling about how all planes have bombs, everyone there was turbulence we could go into a spiral, the plane engines could blow up, etc. It was clearly making passengers uncomfortable because they kept turning around and one lady even yelled at them. I'm honestly shocked the flight crew never said anything to them. I wasn't too worried, except that they ruined any chance to get some rest."
Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."
Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."
Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"
Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."
Cons: "Three of my five most recent flights with American have been delayed. Champs."
Pros: "Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane."
Cons: "Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down."
Pros: "."
Cons: "Delayed 4 hours there, delayed 5 hours on the way back. Messed up plans a bit"
Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"
Cons: "This was my final connection from a long flight, we did a line to check in and get our boarding passes, when we got to the gate I found out I didn’t have a seat number asigned but husband did, they gave me one there but of course it was not next to my husband, it was the last seat available at the end next to restroom. The smell coming out from the it was so disgusting even before th first person went in, they should do something to improve the cleaness in the restroom between flights. It would probably take them 30 more minutes to do so, and I would not mind waiting for it even if this was my final flight after 15+ hours."
Pros: "Nothing"
Cons: "Flight attendants passing out drinks completely skipped us, even though we were looking right at her."
Pros: "Stuck in Chicago. Never made it to Denver because of weather. Had to get hotel."
Cons: "Better accommodations by United."
Cons: "It sucked in many ways. But that wasn't united's fault. The weather was threatening lightning in Denver and of course because of that the world stops turning."
Pros: "Delayed. Bagage mis-rerouted."
Cons: "Be honest when bags are not routed correctly after assuring passenger twice that bags will be at the same airport they were re-routed too. Do not ask passengers for a bag delivery fee when the mistake was United's. Keep passengers informed of delayed flight and keep inconvenience to a minimum."
Cons: "It’s just crowded. The crew was great. Safe landing"
Pros: "Crew was nice and very efficient"
Cons: "Maintenance didn't have plane ready to depart on time"
Pros: "Everyone was really nice, and there was a decent amount of leg room etc."
Cons: "I honestly can't say that I have any complaints about it. Thank you. :)"
Cons: "Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had."
Pros: "Great staff, pleasant flight, nice options on the screen to choose from, etc."
Pros: "We had no difficulties and the crew was friendly and helpful."
Cons: "Awful flight and experience in general. Totally enjoyed being surrounded by individuals vomiting"
Pros: "I was pleasantly surprised this time around with Frontier. Last time I flew with them they were late on the way there and the way back. This time they were on time both ways, even though there was a snow storm on the way back. I like getting to pick my seat and my bags showed up so I was happy."
Cons: "Had to pay $75 because my bag was 7 pounds over the 50 pound limit so that sucked, but it was my fault. On the way back I just reorganized my stuff and avoided the extra fee."
Pros: "Flights were smooth and crew was great."
Cons: "Maybe it was listed in the booking details but everything has been stripped down and everything has an outrageous fee. $45 at check in to check a bag OR carry on a bag , $3 for a soda in the plane, no free snack, stripped tray table, seats don’t recline, poor armrests. I won’t fly Frontier again if given the choice."
Cons: "Due to all the delays on my first flight I just decided To re-book a different flight back I will never fly with this company again terrible the only reason they get a star because I can’t give them nine terrible"
Cons: "I had surgery on my shoulder a week prior to our flight. I needed preboarding .. even after talking to the gate attendant they still failed to notify me and other passengers that need pre boarding .. I got bumped around by several people. The seats were very uncomfortabl, no entertainment, prices were high for in flight food and beverages. I will never fly Frontier"
Pros: "We got delayed because the plane broke down. Everyone else got $100 credit, but I didn't because I booked through Kayak. Could you please give me the credit?"
Cons: "At check in the Frontier gate agent couldn’t get my TSA Pre check number attached to my ticket so I had to spend about 30 extra minutes in security."
Pros: "The staff was wonderful. Great people with great personality."
Cons: "Everything from getting on the plane was not only difficult, but uncomfortable, and with a lack of detail towards the customer. From the small tables at knee level, to the chair angle, this entire experience was either wrought with an inability to sit easily and definitely was painful every time I needed to move."
Cons: "Airline did not let us fly 45 min prior to the departing time, we were a party of 10 people; half of us checked in online and had payed baggage fees online but when ww got to the counter airline assosiate said we did not check in. Not only dod we loose our tickets but also the money for the fees we had already payed for. I had an uderstandong that the gates closed 10 min prior not 45. We had to fly becuase we had an emergency and this inconvinience just made our experince horrible. Defenetly dissapointed."
Cons: "Considering you paid for luggage, no complimentary beverage service and attendants whom expected "team" work to clean the plane, this was the worst example of customer service I have experienced. I travel frequently and very disappointed in Frontier's service and comfort. The space between seats were uncomfortable for a couple of half marathoners. Again quite disappointed and will be avoiding Frontier in the future, no matter the perceived savings."
Pros: "As far as flights go it was pretty ez."
Cons: "$50 carry on fee caught me off guard. I assumed it was 20 or 30...but that’s my fault for assuming."
Cons: "Flight delayed 2 hours. Sat on the plane for an hour of that delay."
Pros: "I like nothing about it and the customer service sucked"
Cons: "I hated everything about spirit I was waiting at my gate for about an hour until they announced all last minute that our gate had changed and the flight was boarding when I went over to the new gate there was no one there and the flight had left! 8 people experienced the same thing and missed their flight. The manager who came to save us was rude and did absolutely nothing about it. I had to find another flight on my own and pay extra and reschedule my car rental and hotel reservations. By far the worst experience I've had at the airport please don't be cheap and think you are saving with spirit, they are a headache and worst service ever!!"
Pros: "Flight wa direct and on time"
Cons: "Crowded!!! Seats too small- middle person spilling over into other seat soaces"
Pros: "The crew was very attentive and professional. The seats were VERY roomy and we even had leg room! No other flights I've taken in the last ten years have had that much room in coach, it was like first class."
Cons: "Luggage charge way too much Crew not friendly or even particularly hospitable"
Pros: "Nothing. I was treated so poorly I walked away from their customer service and bought a ticket on another airline."
Cons: "I was 5 minutes late over their 45 minute required check in window. So they cancelled my ticket. For $100 they offered to reschedule me. And for another $50 they would check my bag. On a different airline I paid another $100 and got a complete round trip ticket, about 10 minutes later."
Pros: "Everything is at an extra cost. From snacks to luggage to picking your seat."
Cons: "On finding that my flight was cancelled, exactly 10 hours before my flight, I cancelled the flight because they didn't have another flight in a similar timeframe (it was just a 24hr trip). I cancelled the flight and they only gave me back credit for another spirit airlines flight that I must purchase in 60 days. They never gave me a reason for the cancellation. I then tried to call into their customer service line, which was completely disconnected (this was the number online and the one they had shared with me via email). Needless to say I will never fly with spirit again."
Pros: "I booked via Kayak and knew there was a charge, but I didn't notice a spot during booking to add it. I assumed a $25 charge, and was surprised by the $50 at the check-in counter."
