Airline reviews
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 very friendly"
Cons: "the seats are horribly squished and uncomfortable. It’s the only thing that makes the flight not excellent"
Pros: "No comments"
Cons: "Cleaners had not done a great job. There were paper napkins left over in the seat pocket from earlier flight."
Cons: "Crew was grouchy and rushed past you without really trying to cater to your needs/ get you what you want."
Pros: "Efficient, cheerful crew"
Cons: "Stop making seats smaller! The added revenue from 10 squeezed seats is not worth the discomfort it causes."
Pros: "I got to board early because I volunteered to check my carry-on. Very friendly flight attendants. Love flying delta. They are always consistent and the movies they offer with the gogo in-flight app are always updated and recently released popular movies."
Pros: "Even though the flight was delayed by a few minutes we still arrived on time."
Pros: "The crew was wonderful, the flight was on time."
Cons: "But the seats are so tight that we were definitely elbow to elbow and once seated I was unable to access even the purse that was at my feet. There was no entertainment and the tray table was tiny, not even an indentation for a cup!"
Pros: "Smooth flight, on-tome departure"
Cons: "Service in business class left a little more to be desired. I had to ask for food and drinks, because I feel off to sleep in the first round. Came to Gate early, but had to wait for agent to put the jet bridge. Only one person was available."
Cons: "Super cramped rows. No leg room at all. Delayed awaiting takeoff."
Pros: "Flight was super short."
Cons: "Flight attendant stated that phones couldn’t be used for the duration of the flight; even in airplane mode The gate and terminal changed at least 5 separate times before boarding."
Cons: "Lots of delays and sometimes confusing communications from the airlines about departure times."
Cons: "Seat wasn’t comfortable and the on flight entertainment didn’t work. AA in flight WiFi kept giving error messages"
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: "MIA to EZE we got the priority seats and it was worth the extra expense."
Cons: "Honoring paid reservations. Our flight was cancelled and rescheduled 4 times within the last few days. Communication. No one emailed me or called me to give me options or to even tell me they were kicking me out"
Cons: "Larger plane. Had to crouch all the way to my seat. Seat was comfortable enough."
Cons: "British Airways but the flights were operated by American Airlines who I've always had terrible experiences with. This was no different. TOTAL NIGHTMARE"
Cons: "When I made the reservation the code indicated that we would be able to purchase food on the flight. When I asked, the flight attendant said, nope, only choice is a pack of two cookies. We were starving on the 3.5 hour flight."
Pros: "Very helpful crew."
Cons: "Too often the video screen I’m given doesn’t charge up and it has to be replaced mid flight. This happened again during this flight when 2 screens didn’t charge and had to be replaced before the movie ended. The crew was helpful, but this problem is annoying."
Pros: "Boarding was great"
Cons: "Inflight Services was horrific and my stuff was damaged in my luggage."
Pros: "What flight are you talking about!? Airlines had NO SUCH FLIGHT! This household became very upset over some surprise obligation!"
Cons: "The turmoil of your false alarm!"
Pros: "The sleeper seats. Flight attendants"
Cons: "Temperature during the entire flight was too cold! Food was not great for a first class flight!"
Pros: "Boarding went smoothly for the most part."
Cons: "7am flight from Baltimore to LAX. How late in the morning does it have to be to get a cup of coffee? No beverages were offered until approximately 3 hours into the flight. No free snacks or purchasable snack options were offered. UNITED PRIVATE SCREENING WAS TERRIBLE!! Neither my companion nor I were able to watch any program or movie without constant freezing and buffering on our 1 year old iPads. It took me 2 1/2 hours to watch a 90 minute movies. Pathetic. Not ready for prime time."
Pros: "Arrived early. Airline offered free bag checking when plane looked full"
Cons: "Size restriction on personal item was smaller than other airlines, causing me to use a smaller backpack than I would have prefered."
Pros: "My seat neighbors were friendly. I didn't take a look at the provided entertainment since I had had to wake up at three in the morning."
Cons: "As far as refreshments are concerned, I wish there was a bit more variety in the provided snacks, and the drinks cart came more often."
Cons: "Heading from BWI to Newark to Boston on 9/29 on United. There were delays at Newark airport which lasted about an hour, and meant that we would be super tight getting in for our connecting flight. We had been told ahead of the departure of the delayed flight that there would be someone on the ground at Newark monitoring the delayed connecting flights, in case a flight needed to be held. Well, we actually landed about 15 minutes before our connecting flight was due to take off. However, we quickly found out that not only were the gates closed early, but the flight tracker was showing the flight had actually left early. There was clearly no communication between on the ground crews, and everyone working at the airport once we landed seemed confused about the situation. By the time we got within eyeshot of our gate, the gate agents were telling us that the Boston flight was already closed. This meant that no one was even monitoring the situation for us, and that they made no effort to hold the plane for the five of us who were supposed to be on that flight. Additionally, that was the last flight to Boston from Newark, so they literally didn't give one iota of care for our situation. I had a 10am wedding to attend that next day, and even after telling the agent this information she still asked me whether I wanted to get on a 10:38am flight to Boston, which made exactly zero sense. After all of this, she ended up getting me on a flight into manchester (that flight had been delayed for 3 hours by this time, and was delayed again after I was booked on it) which landed at 1:24am, a full two hours and some change after I would have landed in Boston, and a full hour away from Boston. Luckily, my boyfriend had his car and was able to pick me up. I finally got to Boston around 2:45am. My suggestion to the airport crews is to actually communicate when you have issues like this. It wasn't our fault, but we were greatly inconvenienced and they did not make an effort to prevent the situation at all. Adding to this, our pilot for that first flight told us that the reason for the first delay was that Newark was congested with too many flights into and out of the airport. THAT is entirely their fault for not being able to properly gauge their own capacity and should not have ended up inconveniencing passengers! I end all this with an additional inconvenience- when I arrived for my flight on Sunday at 4:40am for a 5:55am flight back to DC, I was told that my return flight had been CANCELED. Somehow, in rebooking me on the flight to Manchester. So I had to spend 30 minutes on the phone with United to get that fixed at 5 in the morning and nearly missed my return flight due to crew incompetence as well."
Pros: "Both flight were delayed and I had to reschedule my flights and miss my arrangements."
Cons: "It looks like that there is no respect for Time ."
Pros: "Despite delay, pilot made up time in air and we made our connection in Denver. Advice to download United app for free entertainment ahead of takeoff meant we didn't miss the chance to offer movies to our kids on flight. In-flight crew was incredibly friendly/helpful."
Cons: "Gate attendant was INCREDIBLY unfriendly - made no eye contact or completely ignored our verbal greetings/thanks during early boarding w/ our young child. Delayed an hour out of Baltimore, we were worried we'd miss our connection."
Pros: "Not much"
Cons: "Baltimore to SF was delayed 30 min too Service need to improve"
Beware that when flying into Atlanta with Frontier, you will wait for your checked bag for a full hour after arriving at the gate! Do NOT recommend Frontier if Atlanta is your final destination!
Pros: "Nothing."
Cons: "Social distancing guidelines should be applied on plane. Rather than leave 20+ seats empty, and cram everyone 6 to a row. Flight was over 2 hours delayed due to not having maintenance staff available. And then I was crammed in next to an oversized individual where we couldn’t even keep the armrest down."
Pros: "The legroom we paid for."
Cons: "This time the attendant still wouldn’t let anyone in rows 2 & 3 place the carry on they had paid extra for in the overhead bins, but she didn’t make me put it under the seat in front of me (this losing the extra leg room we paid for), so I put it in a bin behind me. The plane was late, but the pilot made up most of the time, but then it took 55 minutes to get our luggage."
Pros: "The crew was great. In a good mood and accommodated my requests. (For complimentary water and a trading card to remember my trip)"
Cons: "Seat was awfully uncomfortable. I’m only a slim built 5’9” woman and my knees were indenting the next seatback. And the aisle was too busy for me but that could have been fixed with paying for a window. I do not recommend flying in these economy seats for any longer than 2.5 hours."
Cons: "Delayed take off with no reason explained, roughly an hour"
Pros: "It was fast service!"
Cons: "They charged us for every laguage we had. They also charges for drinks!? Seats cant recline.."
Pros: "price was amazing! customer service did their job but with little-to-no empathy."
Cons: "the flight was delayed, which i knew about. then it’s was moved up, which i wasn’t informed about until i walked to the gate to find it empty."
Cons: "They should start boarding from the rear of the plane to the front so that people sitting in back don't have to wait for people in the front or middle of the plane to stow their bags."
Pros: "Price Comfort You can pack a backpack for a short trip and not pay baggage fees. Haven't had a delay in a long while. No cancelled flights since flying with them Boarding is typically fast and we typically arrive 15-30min early"
Cons: "Crew is hit or miss Price of onboard snacks is ridiculous"
Pros: "Crappy cramped seats that you have to pay for?! All the extra fees make the flight more expensive than better airline companies like American airlines"
Cons: "Everything"
Pros: "Literally nothing."
Cons: "I was told my flight was delayed at 3:40am the morning of my 11:00am flight. My flight was delayed 3 different times. I live far from the airport I flew out of so this was a large inconvenience. We were never even told why the flight was being delayed. My entire 5 hour stay at the airport we were never updated once on the staus of our flight. I was also charged over $100 for just my bags and my seat. $45 for a carry on bag is ridiculous. I paid more for my seat and bag than I did for my actual ticket. Paying $13 to sit in the very last row is stupid. I will never be flying with Spirit ever again. Legitimate robbery. The website and app were also slow and hard to operate."
Pros: "If you’re traveling light and you understand their fees, it’s easily the cheapest flight you can get. Maybe not the best airline for all your travel needs, but awesome for a quick weekend."
Cons: "Delays and more delays. 3.5 hours delay boarding. Had us get on plane after first delay, then announced there was no crew and we had to get back off. Nothing is included. Carry on $55, soda or juice $3. Not comfortable. The plane sounded like it was about to fall apart when we landed. Worried for my flight home."
Pros: "The price"
Cons: "I went to check in and the kiosk wasn’t working for anyone!! But they wouldn’t let you get agent assistance without going to the kiosk first. There were only 2 agents working behind the counter, and 3 walking around. The 3 walking around wouldn’t answer any questions. I was supposed to be tsa-pre check. it said it in the system but wouldn’t print on my ticket. She didn’t try very hard and told me to just explain it to the tsa agent. Riiiight, like they would believe me! They didn’t. The crew on the plane were fine. The seats are horribly uncomfortable, but again you get what you pay for."
Cons: "Dirty Seat doesn’t recline Seat doesn’t have head support on sides No movies No phone charger Small food tray Poor food choice No free water"
Cons: "The seats are super cramped. It would be been nice to at least get some water for free."
Pros: "The fact we didn't sit on the plane for an hour after boarding on time so they can kick people off the plane for over booking like they did on the way back."
Cons: "I got an email at 8am saying my flight could be delayed but should show up on time. My flight was at 4:55pm so great start there. So I show up an hour and a half ahead of boarding, which is on the latter side for me. Security lines weren't very long, they just took their time which wasted everyone else's. I get through that line, look at the departure board - wait IT'S ON TIME?! They start boarding soon if it's on time and it's a further gate so I run down there and guess what? Delayed an hour. Okay, that's fine. Go grab something to eat, come back, settle in for a little bit, board - on my sweet way. Go grab some food quickly, come back - another hour delay? What the heck? I must've missed an announcement. Guess I should plug in my phone for the wait, I expected to meet some friends and potential clients layer that night, communication is key. I misplaced my charger, no big deal just went and got one of those power rods (highly recommend) and come back - ANOTHER HOUR?! That's pretty insane. One of my friends flying from Dallas that departed at 7:30 could be up in the air before I am. Step aside, give him a call to update, call potential clients letting them know I will be delayed getting there. No issue. Turn around - my goodness well what do you know, another hour! At this rate I call my hotel, because I can't lose my reservation if I can't check in on time. Hotel was the waterfront crowne plaza (another highly recommended item in this review by me). I plant in my seat, set my roots, meet a few nice people. Figuring I'd kill some time by meeting some great people. Met a family from Detroit and got some awesome food recommendations. Randomly over the speaker - we have another delay - another HOUR delay. Well this is just turning into a horror story, will I ever get there? Should I request a new flight? My buddy in Dallas departed 3+ hours after I was supposed to, and was up in the air already (he landed before me too). At this rate I cancel my meeting. We board, we take off, we land. Woman sitting next to me was nice. Plane didn't crash. Just landed in Detroit about 7+ hours later than expected. All in all, don't take spirit. Looking at prices they are the cheapest, not by a huge margin though. Pay the extra 70 or so dollars to take another airline. Even if it's $150 dollars more, take the other airline. They want to charge you 65 dollars for a carry-on. Their website was created by a 12 year old. Simply getting your boarding pass includes cross and up sells that make the process 10x more frustrating, especially when you know what you're dealing with on the second flight back. (By the way spirit if you can read this I'm a consultant for advertising, digital media, and UI for e-commerce - I can help you with your terrible website and the offers that come along with it) Just take the other airline, any other. It won't save you money most likely, but it will save you a lot of headaches, time, and embarrassment."
Cons: "Someone from flight network called me the day before my trip asking for personal information. I hung up on him."
Cons: "It cost us over $200 extra to take carry ons. I didn't read this in the fine print. $59 each carry on! Each way!"
Cons: "The customer service representatives were extremely unhelpful and showed zero interest in assisting with customer request. I will never fly with Spirit Airlines again"
