Airline reviews
Pros: "The crew’s positive energy and great service were truly amazing. Kudos Delta!"
Pros: "The crew’s positive energy and great service were truly amazing. Kudos Delta!"
Cons: "Not enough leg room. Flights are costly enough and it just seems wrong to upcharge passengers for more legroom. Legroom should be standard outside of first /business class."
Cons: "Delays both in DETROIT and a huge delay in Shanghai."
Cons: "It felt like the flight attendant had a long day. Chairs weren't super comfortable."
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."
Pros: "Love the fact that the head rests move to support your head better."
Cons: "The flight was 2.5 hours late. Then it was freezing in the flight. I let the crew know and it warmed up at the front and back of the plane but it was unbearable in the middle. It took me two hours to warm back up!"
Cons: "Too much delay - departure was planned on March 15 @ 7 pm and take off happened on March 16 @ 12pm - a complete failure!!!!"
Pros: "The seats were awful .how many can squeeze in. .horrible"
Cons: "Room to breathe, move a little"
Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."
Unlike other airlines, did not allow for basic economy flexibility for new COVID spike. Disappointing.
Cons: "Passenger that sat next to me occupied part of my seat."
Cons: "Flight was broken we had to get off. I had to book a hotel room was so tired"
Cons: "Try not to loose my luggage next time full of my family’s Christmas gifts. It was a short flight and a giant Leopard print bag. Crew was rude, didn’t wake me to let me sit up. She just shoved my seat forward"
Cons: "We are stranded in Miami due to another passengers medical needs. That delay caused us to miss our Connecting flight. We are now unable to get to Belize until Friday and the best they will offer is a coupon for like $30 off a crappy hotel. Next time I’ll lsy more for delta’s far superior service"
Pros: "Flight was on time. They fed us two meals."
Cons: "Seats in coach are incredibly cramped, and blankets are comically small. The food was pretty terrible and the vegetarian option not particularly nutritious."
Pros: "The crew were great and the flight was quick."
Cons: "The blankets are really thin and so we were cold. They do not offer eye masks anymore. So sad"
Pros: "Crew was kind & friendly. They found my wife and I empty seats where we could stretch out. Food was great too. No complaints."
Cons: "N/A"
Pros: "Boarding, entertainment"
Cons: "Arm rests were immobile, meaning could not take advantage of empty seat next to me."
Pros: "I like the fact that I made it to London alive. The turbulence was so bad and the pilot never came on and reassured us I was shaking and nervous all the way across the ocean"
Cons: "The boarding issue to me is a big problem you should put the conditions of the ticket up front and center for example boarding last when you are on an international flight with bags that need to be put in the overhead is a big problem having to pay for each seed internationally for each leg of the trip made my ticket just as expensive as if I had bought it from a regular company never again will I use your service rip off rip off. Once you buy the ticket then you send clarification letting the passenger know they have no rights I had no right to anything I was wondering if they were going to tell me I had to clean the plane in order to be transported from New York to Spain. A satisfied customer is a repeat customer you got over on me once but never again"
Pros: "The new premiere plus was pretty nice and roomy with recliner feature and big personal screen. I'll try this again."
Pros: "Good crew"
Cons: "This flight had no snacks or drinks and was also delayed what else is there to say."
Cons: "The breakfast could have been more substantial than just a muffin. But everything else was very good!"
Cons: "Missed connecting flight from Copenhagen to Geneva since flight from Newark left over an hour late.. They booked me on a flight to Zurich and then to Geneva. Had a connection to France booked separately that I had to move."
Pros: "Flight left on time and arrived almost 30 minutes early."
Cons: "The general shrinking size of airplane seats is ridiculous. And one of the restrooms was not locking properly."
Cons: "Serious delay, deplaned once and arrived 5 hours late with no real reasom."
Cons: "Pretty much everything I hated, starting from the time they charged me extra 100 bucks for second luggage which was mentioned as free both by kayak and Lufthansa to me, major breach of customer trust. Apart from that the crew was in general rude, didn't find the experience anywhere close to comfort"
Cons: "I was seated right behind first class. While still on the runway and for about the first 15 minutes of flight, There was literally a few frozen water drops, condensation I guess, dripping down on me because it was like a walk-in cooler. I asked for a blanket and the flight attendant said they were for first class only. He did then get me one and said "I had one left." Obviously a lie... but I was grateful for the blanket at that point because I was very cold. Other than that it was a fine flight and check-in was a breeze online."
Pros: "We liked the fact that George and Amanda were so very nice helping us when our flight was so late that we might miss our connecting flight. They assisted us getting seats on another carrier."
Cons: "We didn't like that they kept changing the times we might be departing. One minute it's an hour, the next it's 2. No consistency."
Pros: "It was spacious"
Cons: "When the captain talks on the radio it is super loud and when the flight attendant talked you could not hear what they were saying"
Cons: "The seats were not super comfortable, nor did they recline. No snacks, drinks or even a small bottle of water was served. We thought that the seating arrangement would take Covid 19 into consideration, & have the passengers spread out a little bit, but no, it was a full flight, we were sitting right beside other passengers, both on the outgoing flight & the return flight. We dislike that there is a fee for carry on luggage."
Pros: "The crew was amazing and the communication was great. The flight was not bad and was handled well"
Cons: "The seats were less padded than expected but were surprisingly bigger. They don’t recline. I brought my own “padding” and slept through the flight"
Pros: "1 flight attendant out of 3 was genuinely kind."
Cons: "Delayed flight without explanation caused me to miss my connecting flight and the airline did nothing for me until I directly asked about all my options. There were few. I ended up waiting in an airport for 10 hours to catch a flight to an airport that was not my original destination, to wait 8 more hours for a bus so I could ride 2.5 hours on the bus to my original destination. Last time I ever fly with that airline."
Pros: "Boarded timely, crew was polite and efficient. Cabin temoerature was comfortable"
Cons: "It was a 3 hour flight and no service was offered. If you wanted a water or anything, you had to either ring the call button or go to the galley and ask"
Cons: "While I was on my way to the airport, I received an email (3 hours before the aircraft was scheduled to take off) stating that the flight had been cancelled. I tried talking to a Frontier representative but every time I called their customer service number it was all automated. I was unable to speak with someone regarding the situation. I ended up having to spend $600 to book another flight with American Airlines due to my need to be in El Paso, Texas today. I still have not been able to speak with anyone at this point."
Cons: "No power outlets, seats didn't recline and were very hard and close together. Arm rests were hard and hurt my arms. Floor was filthy and so were the bathrooms."
Pros: "The staff seemed quite nice."
Cons: "The seat padding reminded me of what I imagine they would have in the trustee's area at a correctional facility. Also the "tray table" was not really big enough to support an open paperback book and definitely not a magazine."
Cons: "The plane needs to be cleaned. There is dirt and grime around the windows, on the little tray infringed of the seat and my seat had crumbs on it."
Pros: "Great take off and landing as well as in flight service."
Pros: "Not much"
Cons: "Paying for bags, paying for water and snacks, delayed because they overbooked and let too many people on the plane"
Pros: "In addition to price, I was assigned an aisle seat without paying extra"
Cons: "This Florida base crew at most was average compared to the crew assigned on my flight out of Baltimore. Maybe because it was an early morning flight."
Cons: "Horrible airline. But I knew that. Didn’t have much choice on short notice. I avoid this airline as much as humanly possible."
Pros: "The low initial ticket price"
Cons: "Having to pay for a seat and baggage after buying a ticket. I got an earlier standby Delta flight on Friday so I skipped the first Spirit flight (which ended up being delayed anyway). On my flight back to Denver today, I found out in the terminal that my entire trip was cancelled because I missed my original outgoing flight. I was never notified of this cancellation through email or phone call. I was then asked to pay another $200 for a one way ticket back to Denver. Luckily I was able to fly standby on Delta again instead. Never flying Spirit again. Terrible customer service as well."
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: "Nothing"
Cons: "I arrived at the terminal three hours early, connecting from a non-Spirit flight from Central America. Spirit employees wouldn't check me in, saying they were too busy and I need to wait, but no worry, there's plenty of time. Asked again later and was told to check in online. Checked in online and was told (after the many upsell screens) that I couldn't print a boarding pass and needed to go to a Spirit counter. Went back to the Spirit gate and they said I hadn't checked in so they gave away my seat, and they didn't have another flight until tomorrow. Did I want it? Nope. Bought tickets on a real airline. Will never, ever travel with Spirit again."
Cons: "The seats are cramped and on the way back, they canceled all flights back to Houston, causing us to pay an extra $600 in order to get home to work on Monday."
Pros: "Absolutely ridiculous policy on making me go to a different terminal to get a boarding pass. Every other airline in the United States can issues electronic boarding passes these guys blocked me out 1 hour and ten minutes before the flight and said I had to go to terminal E counter to get boarding pass. I was at terminal A. Because I did not have boarding pass I could not enter through terminal A and use skylink I had to take the bus instead. That took 25 minutes. Then when I arrived at counter they said the flight was closed. And even though it was 25 minutes before boarding I was out of luck. The rude counter person said I should have been there 3 hours before the flight and now all they can do is reschedule for another day and it will cost an additional $100. Fortunately there were about 10 other people in a similar situation as mine and it became overwhelming for the counter people and they started issuing us tickets. This caused 10 of use to rush to security yelling we only have 10 minutes to get to flight. Fortunately all the people in line were understanding and TSA did the best they could but it still took time and probably stressed everyone out at security including TSA. This was just a money grab by Spirit airlines. Any other airlines an electronic ticket would have issued to my phone and I could have entered security at terminal A, caught skylink to Terminal E for my flight and been at gate 30 minutes before departure. This ridiculous policy of locking me out over an hour before the flight caused a great deal of stress to myself, the spirit counter crew, the TSA, all the other airline passengers waiting at security, and all the other spirit passengers who were gamed by Spirit airlines moneygrab. I intend to file complaints with Better Business Bureau, FAA, and Homeland security. This was totally unnecessary chaos!!!!"
