Cons: "Had to wait for a gate for about 10 minutes after landing"
Pros: "Crew was funny and had a sense of humor, especially regarding the safety instructions."
Cons: "Free Wifi. Paying for it is silly as ticket prices are expensive anyways."
Pros: "Crew, entertainment"
Cons: "Free messaging wasn’t working. I tried imessaginb and whatsaap but it wasn’t working properly. The boarding process is usually super cramped. They can space out the pillars a little more so that people don’t have to squeeze in. Wish they had more snacks like sandwiches and stuff for purchase"
Cons: "Plane was late coming in so we were late leaving."
Cons: "I always miss drink service when it's not there."
Cons: "Ground staff was rude to me. I was trying the self check in and got the bag tags. I just asked the lady at the counter to help me but she got annoyed."
Pros: "Crew was good. On boarding was smooth"
Cons: "It’s a 4 hours flight. Snack has to be better."
Pros: "Jet blue flights seem generally good. Like the WiFi access to be Able to use flight time efficiently."
Cons: "Had to check carry on and go to baggage carousel delaying my getting out of the airport"
Cons: "Had to check carry on and then go to baggage carousel delaying my getting out of the airport"
Cons: "JetBlue's livery is really beginning to show its age. The entertainment screens flicker and flash and the once-luxurious leather seats appear worn. The crew is still great, as usual, and our flight in general was excellent."
Pros: "Legroom!!! JetBlue sets itself apart from the rest by letting you breath in your seat!"
Cons: "Entertainment / access to entertainment on the app was mediocre"
Pros: "The crew was friendly and seats seem to be bigger than other airlines"
Cons: "My tv was broken, and that has been one of the amenities on jetBlue that is normally marketed somewhat heavily so it was a bummer. The flight was also delayed for weather reasons (I know that is not their fault, but it added to the general bummer of a flight)."
Pros: "Personalized service, even in economy. Friendly faces, who seemed intent on providing the best customer service."
Cons: "Not much."
Pros: "The flight was shorter than expected"
Cons: "It would have been better avoiding a delay but the crew arriving in time to the plane and another 20 min delay in the plane after leaving the gate"
Cons: "I pressed button for flight attendant help and no one came. Flight was delayed and made me miss appointment, turbulence, drinks weren’t served until the very end of the flight. Not pleasant."
Pros: "The boarding time was delayed two hours and then changed back to the original time half an hour before boarding."
Cons: "The boarding time was delayed two hours and then changed back to the original time half an hour before boarding."
Cons: "The crew was overly aggressive with mask policy enforcement. They patrolled the aisles and routine pointed at passengers directing them in a hostile manner to keep their masks on their faces, even when they were trying to eat or drink. They also threatened customers by stating it was a federal law several times. It was very uncomfortable to say the least. I will not fly delta again by choice."
Pros: "Crew was friendly and engaging"
Cons: "I wiped down my seat area to clean it. It would be nice to know what Delta is doing as well."
Pros: "Crew was exceptionally nice. Live DISH TV unexpected and appreciated."
Cons: "Flight was freezing. Crew was overly concerned about my tree nut allergy. Been flying for 40+ years and this was the first time any one has asked...appreciate it but they went overboard"
Pros: "It was all good glad the last leg of the trip was pleasant."
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Pros: "Crew was very friendly"
Cons: "the seats are horribly squished and uncomfortable. It’s the only thing that makes the flight not excellent"
Cons: "The unfortunate delay prevented me from attending my grandmother’s wake. Fewer delays would be helpful."
Cons: "Announcements were too loud in earphones (could damage ear drums) and entertainment was turned off while waiting 30 min for the gate to open."
Pros: "No comments"
Cons: "Cleaners had not done a great job. There were paper napkins left over in the seat pocket from earlier flight."
Pros: "On time."
Cons: "When I checkied in online for my flight i had to pay for the seat, as well as for my carrying luggage. No idea ahead of time these fees would be added."
Cons: "Got another plane or somehow figured out a way to get us home instead of being delayed 6 hours."
Pros: "On time and comfort of leg room"
Cons: "The gates are at the far end of the STL terminal"
Cons: "Why should we have to buy a seat after already buying a ticket to check-in. The check-in process should be separate from the seat buying process so passengers can check-in without having to buy a seat like all other airlines do. You need to maintain the basics."
Cons: "They could upgrade like some of the other airlines and add entertainment of some kind to the flights"
Pros: "Well considering I lost my wallet on the way to the airport and was unable to check in. I would have to say I didnt like it"
Pros: "The inflight crew were great. The price of the tickets were also good."
Cons: "The crew at the check in on our way out of nashville had the worst attitude I have ever experienced from an airline. They got us quickly up to the counter (good) but when I had to ask questions because I didn’t have time to read the signage they got an attitude with me. “Didn’t you see the sign?” And turning to another employee, “isn’t there a sign with all the information posted?” Same employee came down to the terminal and announced the wrong destination for our flight while we were boarding. On the way out of Miami and back to Nashville the crew had great attitudes but it was so disorganized we had the longest line to wait in to check in for both concourses. People were going to miss flights. They fixed that eventually but I’m not sure they did it fast enough for some. Getting through security was far faster than check in. Also, they nickel and dime you for luggage, snacks, etc. It’s a no frills flight. I’ll probably give them one more chance though."
Pros: "Our flight was delayed over 2 hours and there was ZERO notification from the airline - we found out once we were at our original gate. Paid substantial amount to check bags and for seat assignment......after choosing seats when flight was booked online! Crew and flight were fine but will not fly Sun Country again. Too much hidden BS!"
Cons: "See above"
Pros: "Portland, Oregon agent customer service"
Cons: "This weekend has been an awesome spending time with my Arizona family..... but my experience at Phoenix Sky Harbor International Airport is DEFINITELY NOT "America's Friendliest Airport" as they like to advertise throughout the airport! When I went to check in with the exact same airline that the 7 of us flew out on, Sun Country Airlines, I was told that my bag was suddenly 9 pounds heavier than when we left.... even though my bag was packed EXACTLY the same and nothing had been added. As we were finishing up paying, a random lady from the ticket counter stopped me and in a very snobby and aggressive way told me I needed to check an additional bag. I was BEYOND CONFUSED because this bag was considered a FREE "personal item" when we left Portland and now I'm being forced to pay an extra $40 dollars. She then started talking to me VERY aggressively and belittling me as if I couldn't afford the extra charges. That was not the problem! I wanted an explanation as to why the policies are suddenly different just 72 hours later? After I re-ran my card and paid the additional charge, we start to leave again, AND THE SAME GIRL tells me I need to check ANOTHER BAG that was considered a "carry on" when we left Portland. She was starring at my family, our belongings, not listening to what I had to say and continuing to harass us, while demanding I pay more money, without answering any of my questions! I spent $120 to check our bags just to get back home- $75 more than when we left! I asked for her badge number to reference my conversation with her when I call and speak to her manager and she refused to give it to me! Her body language was defensive, unapproachable and snobby- rolling her eyes multiple times.I was able to see read her name on her badge before she flipped it over, "Mika" who happens to be based out of Portland International Airport but working out of Phoenix Sky Harbor International Airport today, December 10th. Sun Country Airlines advertised themselves as "travel convenient and trouble free for all passengers"...... WHAT A JOKE! I will NEVER fly on this airline or recommend them to anybody ever in my life! This has been the WORST TRAVEL EXPERIENCE AND CUSTOMER SERVICE in my life. #DoubleWhamy #SunCountryAirlines #SkyHarborInternationalAirport #AmericasWorstService #DontFlySunCountry #NotFamilyFriendly"
Pros: "Quick boarding"
Cons: "After quick boarding we waited 30min after departure time for luggage to be loaded"
Lots of turbulence on this flight, which limited beverage service. Despite the length of the flight, there was only one beverage service, and the "snack" they handed out was a single packet of Biscoff cookies. It was a newer plane with outlets for plugging in devices and a shelf for placing a cell phone to view -- all that was great. The free entertainment was also great and much appreciated, as my husband had finished his book and needed something to amuse himself during the long trip. But if the airlines could just give us passengers a bit more seat space, it would improve things immensely; the guy next to me was well over 6-feet tall, and he couldn't help but extend his knees into my space.
Pros: "crew was great and moved me further up in the plane to make a tight connection"
Cons: "food"
Pros: "Crew were amazing"
Cons: "WIFI please for the god sake it’s a transatlantic flight"
Pros: "Smooth price getting boarding pass and we were anytime sit together"
Cons: "All good"
Pros: "Flight diverted. Poor communication"
Cons: "Realistically explain options of what may happen due to weather issues"
Pros: "Seats seem to get smaller but overall a good experience"
Cons: "Seat room"
Pros: "Movie selection was good"
Cons: "Fortunately I ate breakfast before getting on because I was only offered two stale cookies on board"
Pros: "Smoothest flight ever"
Cons: "Terminal at Ohare is terrible. Severe shortage of restrooms, poor signage"
Pros: "Nothing"
Cons: "You were late per usual. I wouldn’t have a job if I operated like you. It would be nice if there was some accountability"
Pros: "The boarding was quick and easy and the lights were dimmed as it was a red eye flight. Couldn't have asked for anything more."
