Pros: "When we did get in the air, the flight seemed to go quickly and we got there fast."
Cons: "I upgraded to 1st class for both flights but the plane seating was very dismal and hadn't been upgraded in either of these planes for a long time. After we boarded the plane we were told that no drink, snacks or food would be offered. The attendant shut off the lights as soon as we got in the air and kept it dark in the cabin until 10 minutes before we landed. She never came around to check on us once or ask if we needed anything. I was so thirsty when we landed. I have decided that I will either go back to United Airlines or check out the 1st class options at American Airlines better next time. This might not have been their fault, I'm not sure what it was, but the flight was late landing and we took off an hour late as well which really put me behind schedule."

Cons: "90 minutes late, changed terminals on us right before boarding so another flight could have our plane. No leg room, crazy landing and stale pretzels."

Pros: "On time, nice stewardesses who kept after drinks, offered refills, good snack(maple cookie) pilot again commented. Comments on turbulence especially calming. Also like a little geography like what river we are over. Deveops personal relationship"
Cons: "It was a fine flight but let me talk about boarding in general. After your special groups seems like you should load back of plane first? Window seats first? Boarding is a series of hurry up and wait experiences. I do not like feeling like cattle waiting in gate ramp or walk then in aisles. Must be better way. Please don't let people bring on 3 personal items and carryon. Make them check carryon or?"

Pros: "Nothing"
Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag. What is baffling is that when I arrived at Denver people were getting complementary check in baggage. I’m so dissatisfied with the booking and the amount it has now cost me ruining any savings I’d had for sanfrancisco"

Pros: "We arrives early."
Cons: "Very long walk to next gate. No golf carts wanted to bring US. Wife is pregnant"

Cons: "Crowded planes."

Cons: "delays were long, video sound is too loud for an evening flight. too many adds play on the screens and over the PA system"

Pros: "Good. Thank You united airlines.!! Excellent 10.00"

Pros: "One if the bathrooms was closed and a second one had no running water."

Cons: "Immediately after all passengers were boarded United discovered the plane had to be replaced. We all had to deplane, wait an hour more for a new A320, and reboard. Also irritating that delays are posted at 15 minute intervals and then updated; so you have to keep updating friends & family via WiFi. If it's predicted to be an hour, say so."

Cons: "my checked luggage was delayed a day"

Cons: "There were no blankets"

Pros: "Agent was able to get us on an earlier flight. She was very helpful and friendly. 2 of us shared 3 seats in the emergency row."
Cons: "Pay entertainment. Can’t shut off screen. Cycles same ads. Super annoying! Seats are crammed. Service is as minimal as they can get away with. I prefer delta! Don’t fly United if I can help it."

Pros: "The plane was not cleaned prior to departure so the bathroom was disgusting. One of flight attendants cleaned it , probably not her job but appreciated. The staff was terrific with an exhausted group of passengers."
Cons: "This flight was more than two hours late. The updates were not shared at the gate and we were strung along about the departure time. If a person didn't have the app, little to no info was available."

Pros: "Repairs caused a long delay, they kept us informed but it was a hurry up and wait forever"

Pros: "The flight crew was very helpful and very nice. I was traveling with my 7 month old daughter by myself and the crew made sure I was taken care of."
Cons: "When I got off the plane and was waiting for my stroller and car seat to be brought up from the cargo hold, I received the car seat first in good condition. My stroller, however, had the clip busted off that connects the car seat to the stroller and cannot be replaced. So my entire travel system is now unusable. I know this happened on my transfer from Houston to Denver because I had to use my stroller when I got off of my flight from West Palm Beach to Houston and the entire thing was in tact. This is extremely frustrating because this travel system is $450 and is now unusable. And what's even more frustrating is that these items have to be gate checked and are given "special handling" tags when they are checked. The clip that was busted off is a pretty substantial piece so my stroller had to have been handled extremely poorly in order for this clip to bust lose."

Pros: "Once again, United was exceptional in providing the utmost care and service for its passengers."
Cons: "No complaints."

Pros: "Nothing"
Cons: "Nothing"

Pros: "Nothing"
Cons: "6 hour delay. Sending the plane from Denver to salt lake and back to Denver before a 7:55am flight was supposed to take off . Having 1 person on the plane from Salt Lake to Denver. Forcing a full plane of Denver durango customers waiting for 6 hours"

Cons: "The Gates changed,Flight Delayed half an hour."

Cons: "Limited overhead space"

Pros: "Busy & hectic with a very full flight, but staff was attentive & friendly."
Cons: "All fine"

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

Cons: "Bad communication between crew and guests . We sat on the runway for over an hour before them told us what was going on . The most rude and awful flight attendants I've ever had . Same thing with landing no communication as to why it took so long till the end , over all I'll prolly never fly United again and I would like a full refund ."

Pros: "The best part was relaxing at the United Club before the flight. I will try and book flights with United and go to the club especially when returning home."
Cons: "We volunteered to take a later flight if needed. It was a little chaotic, but the ground crew did an excellent job getting us on the flight."

Cons: "Flight was delayed due to maintenance issue (as usual) and the employeea didn't even try to accommodate with those that had a connecting flight. They were pretty much like oh well, just get a hotel for the night. I swear United hires the rudest people!"

Cons: "Wi-Fi wasn't available"

Cons: "Two delays"

Pros: "Friendliness of the staff"
Cons: "Nothing"

Cons: "Unreliable wifi."

Pros: "It was nice"

Pros: "It was inexpensive"

Cons: "Twice on this trip, the plane was not at the gate, since it needed to be delivered.......In Houston, when it was delivered, the gate agent reported that the interior was too hot, they had to cool it down. Then, after we were all on, the crew arrived, saying they had just been assigned to our flight. Needless to say, the flight was over an hour late, many of us missed our connections and had to spend the night,"

Pros: "Boarding was smooth. Everything on time. Friendly people."
Cons: "Uncomfortable seats. They were a little cramped in the width, but unbelievably cramped to the person in front of me. Spirit has more room."

Pros: "nothing"

Cons: "The KAYAK APP sucks i selected annother date And time And missed the flight as a no show. I selected the date for next thursday And the APP moved it And booked it for the same day. impossible to take it was Erich And not the date i wanted. I reeboked it in UNITED direct payed 75 USD and fixed kayak mistake. Never use this sh...t again"

Cons: "Confirmation number N89G3L. Literally just look at what I had to go through to get from Denver to Liberia and back. In total; 3 cancellations, 9 delays and had to leave the plane after being boarded 3 times in a row at Houston. Unacceptable. I would like to get money back for this trip, as it took off two days of traveling and took us well over 48 hours of travel time within airports. Is there any way I can be put in contact with someone from United Airlines about this? Thank you."

Pros: "New plane, wifi, arrived 27 mins early"

Pros: "My flights were great. The staff were friendly and kept smiles on their faces. They did everything they could to ensure that all passengers were comfortable. The pilots were energetic and kept us informed of every detail regarding the plane and the flight"

Pros: "It was Dec 23rd the busiest travel day of the year. Check in was easy. Courteous help was available. Boarding was a bit slow, but it was a ful flight. We took off on time and landed early. The flight was smooth with helpful attendants."

Pros: "The crew was nice"
Cons: "United has decided it can squeeze another inch or two out of your legroom by making the padding on the seats superthin, which results in not only hard seating, but the tray table mechanism in the back of the seat in front of you projects out a few inches, effectively pinning you in place. The seats recline a total of about 3 inches, which is to say two versions of bolt upright. I spent the entire trip trying to find a non-painful position to wedge my body into, but I failed. I heard one of the crew say they hated the new seats. There was no food. The streaming entertainment system was out of order. This will be my last trip on United."

Pros: "The TSA pre board is the thing since ice cream"

Cons: "Two flights both of which had long delays that were not weather or passenger related. Plane had sardine can seating."

Pros: "Everything was on time"

Cons: "Food options were awful, especially for what they charge for food."

Pros: "Timeliness"
Cons: "Uncomfortable, charged for everything. Not the Frontier of old."

Cons: "4 hour delay with very few updates or help."

Pros: "Not trying to be hurtful, but not much. The people sitting next to me were nice. The temperature was fine. Nice takeoff, flight, and landing. The seating in the terminal was comfortable."
Cons: "The boarding was completely disorganized. The crew unprofessional. I overheard one crew member say to another "What is it with these Denver weirdos?". Then they complained about work and passengers the rest of the trip. I was in the front row and they must've assumed I couldn't hear them. I could. I know you're trying to reduce fares and making it an more a la cart experience, but $2.99 for a can of soda? Having to avoid the pile of ice that was dumped by the flight crew into the bathroom sink when i washed my hands wasn't very pleasant. The chairs are still incredibly uncomfortable, even in my "stretch" seating assignment ($35 poorly spent on my part). This trip made me rethink the cost benefit of taking Frontier. Flying United or American may be worth the extra money. And that's coming from someone on a tight budget. I used to enjoy flying Frontier and love taking a plane in general. I surely didn't this time."

Cons: "When I arrived two hours early to my flight, it was the first time I heard it had been cancelled. Apparently, due to weather. They said the only time they could get me out would be three days from then or they could refund me. No, they refused to pay for another ticket. So, I had to spend $435 on a ticket for later in the day when I had spent $130. Then, I look to Denver's weather and its perfect for the day. I call my mom, she's outside without a jacket! Where is the weather pray tell Frontier. This is the third and last time I ever use Frontier. Frontier is the worst airline I have ever used."

Pros: "Frontier is so cheap. Flight got cancelled and they didn't bother to text or email with alert. Said they could reschedule 5 days later. I'll never fly then again."
Cons: "Everything"

Pros: "Nothing"
Cons: "Everything. Terrible since they got bought out. Used to be a great local airline but not anymore."

Cons: "seat was very uncomfortable"

Pros: "It finally got me to my destination."

Cons: "45 minutes and no bags"

Pros: "Great price, got seat up front, what's to comppain about?"
Cons: "Nothing, it was fine."

Cons: "Delay. On the return ticket they asked for more fee for my carry on even though I had less stuff when I was returning."

Pros: "Original price, before the nickel and diming begins."
Cons: "Nickel and diming us on every single thing. Inability to use the tray table for anything more than a cup of water (that must be paid for). Charging for a carry on."

Pros: "Not much. Frontier got me to where I was going."
Cons: "The seats are too crowded, even for a person who is only 5; 4" tall like I am. They were hard and uncomfortable. I don't like having to pay for everything--including extra money to get a seat. The flight was late getting into Orange County. Then Frontier lost my bag. It was not until the next day that they brought my bag to me the next day. Thankfully Frontier waived my bag fee. I won't fly Frontier again just like I'll never fly Spirit again, and I've recommended that my family not fly Frontier. We will fly either Southwest (the best), or United."

Pros: "friendly people Pilots were great"
Cons: "Checkin lines long. Wrong boarding passes given. Bag checked in wrong when I wS there four hours early."

Pros: "Nothing"
Cons: "Garbage airline"

Pros: "seats are just adeticute love that they don't fold back. I'm 6'4: and 270 lb so that's important to me"

Cons: "Hidden costs for luggage and carry ons"

Pros: "N/A Jose Sanchez 305-763-6132"
Cons: "N/A"

Pros: "Plane left on time"
Cons: "The seats are hard as a rock and they charge you an extra fee to actually have a seat. I wanted to stand the whole time rather than pay the fee but hat was not allowed. Your ticket price is not the real ticket price."

Cons: "Being charged for carry - on luggage. Seats didn't recline."

Cons: "Charged $45 for a carry on is BS! Didn't even get a glass of water. Won't be flying Frontier again. There are other choices!"

Pros: "Nothing...it was horrid"

Pros: "on time, friendly"

Pros: "The seating is extremely restrictive. The seats no longer recline. Seating arrangement is a charge item. Carry on bags are a charge item. In flight beverages and food items are charge items. The air in the planes is low quality."
Cons: "The stewards(ess) are bitchy because they are trying to manage very unhappy passengers. They constantly spout warnings to shut up, sit down and do exactly as they say or you will be taken off the airplane in irons by an air marshal. There is no comfort or piece of mind on a Frontier plane."

Cons: "Being nickeled and dimed to death."

Pros: "Everyone was courteous."

Cons: "Turbulence was bad and no complimentary water"

Pros: "Staff very friendly and helpful"
Cons: "Seats uncomfortable"

Cons: "Very forceful in trying to sell your credit card, over and over you kept trying to sell it. Just annoying."

Pros: "It took off on time, boarding and exiting were faster than I’ve experienced on other airlines. I can’t ask for more and was really happy about it for that reason."
Cons: "It’s a budget airline so entertainment was non existent, but that’s really not important to me."

Pros: "Flight good very basic plane like they don’t even have a pocket holder and the tray is minuscule. The chairs are pretty firm but not bad for my 2 hour flight."
Cons: "My baggage was damaged , found open with one of the contents upon top of luggage, found it after beltmstopped and couldn’t find mine, I asked about it and Spirit lady said it’s to the side"

Pros: "Good flight"
Cons: "Didn't purchase food or entertainment"

Cons: "Na"

Cons: "Not much leg room. They don't serve food. They have outrages bag fees. I don't recommend this airline to anyone."

Pros: "Flight was smooth and relaxing"
Cons: "The delay but it wasn't to long of a delay"

Pros: "Got what paid for"

Pros: "ABSOLUTELY NOTHING!!!"
Cons: "Everything. Glee spirit one other time and completely regret it. Haven't flown with them in 4 years. I remember why now. Flight was originally cheaper but by the time you pay all of there fees to get on the plane you're not saving at all. And once on the plane everything costs a fortune so now you've spent even more. They are never on time in my experiences and don't feel the need to give the paying customers updates. After several hours of delays you get the pleasure of being absolutely crammed in their crappy aircraft. NEVER AGAIN!"

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: "Online check in was great but after printing boarding pass at home still had to wait in long line to just check bag"

Pros: "Nothing bad, nothing outstanding either."
Cons: "With all the baggage fees and the hassle of having to go back and pay for bags online after purchasing tickets, I'll fly a major carrier next time. After crunching the numbers and inconvenience of it all, I didn't save anything by flying Spirit. You truly do get what you pay for...go cheap, get cheap."

Pros: "None"

Pros: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"
Cons: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"

Pros: "Not much"
Cons: "Cost of baggage Web site"

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."

Cons: "Our return flight was cancelled and we received no phone call or email of any kind letting us know. We had a wasted trip to the airport and my buddies vacation time was up the next day so it put him in the hot seat at work. They were very unprofessional at the check in counter while we were trying to figure out what to do. My friend who we were going to see in Denver had flown spirit a few months before to come see me in Texas. And he had some unnecessary issues also with delays and unprofessional personnel. I won't be using them again. Use a different airline."

Pros: "Price was right"
Cons: "Reserved my seat but didn't get it; cramped."

Pros: "FRIENDLY CREW"
Cons: "FLIGHT DELAYS"

Pros: "Ease and price, legroom was ample as well"
Cons: "I didn't like paying for my water"

Pros: "Nothing"
Cons: "Everything"

Pros: "On time! Flight was good. Good option for a good price."

Pros: "The price"
Cons: "The information"

Pros: "Cheap fare."
Cons: "Fees for everything."

Pros: "Everything was as expected. I highly recommend springing for the big seats on Spirit flights!!! It was well worth it."
Cons: "One small bag for a weekend trip is fine, but the price for anything extra is crazy expensive!!!"

Pros: "Short Flight Good communication from the pilot - could have waited 15 - 20 min before actually telling us that we were starting the decent"
Cons: "I felt like a sardine. Sat between two large men, and I was SMUSHED. No comfortable positions - thank goodness the flight was short. The bathrooms were disgusting on the flight."

Pros: "Great overall experience, great price"

Pros: "The crew was friendly."
Cons: "Both of our flights were delayed for two hours with no explanation. Other airlines didn't seem to be having the same problems. It is rediculous that they charge for bags and that they are the only airline with a 40 pound weight limit when all of the others are 50 pounds. They charge $10 just to print the boarding passes at the airport. All of this they claim saves you money on the fare, but with all of the nickel and diming that they do to you after you purchase the ticket, it is much more affordable to go with another airline. I will choose some one else to fly with next time."

Pros: "Nothing"
Cons: "I wasnt allowed on my plane when it wasnt leaving for 43 minutes after i had arrived there. I would have been there the RECOMMENDED hour and a half early if i hadnt run into heavy traffic. Unfortunately, I only had 43 minutes before the plane left denver and the crew told me that i was late and wouldnt even give me the opportunity to try and get to the aircraft before it left. Then they told me that i could pay almost double what i had origionally spent on the flight to wait 4 hours for the next one with a 6 hour layover for thr connecting flight. I had then asked if it was possible to be reimbursed, the guy at the counter started laughing and said no it was my fault i was late. I have never been treated with such disrespect before in my life. I just dont understand, because no where does it say that if you're not there 50 minutes prior to the flight that you forfeit your flight. 50 minutes, i was there 43 minutes prior. Now i wont be able to visit my family for another year because i used my vacation time for that aweful experience with spirit ovwr 7 minutes. Then when i called kayak to explain to them what happened, they told me there was nothing they could do over and over again. Absolutely no help from either party."

Pros: "Crew was polite."
Cons: "The seats were horrible. I was aware that the Spirit seats would not recline but I did not know that they had so little padding. The ones with the gray backs we encountered on the flight to Denver were intolerable. The ones with the blue/black backs we encountered on the way back were better padded but still too uncomfortable for any flight more than an hour. I've encountered cement benches that were more comfortable. Never again."

Cons: "We booked and it took 30 minutes to move because of the AC"

Pros: "Everything was on time and as expected. The pilots were great and maneuvering around a storm outside of Denver."
Cons: "Nothing to dislike, really."

Pros: "Nothing except that the pilot didn't crash the plane."
Cons: "Everything"

Pros: "My flight TO Denver was fine. Nice new plane, crew was pleasant etc."
Cons: "My flight FROM Denver TO Houston was a nightmare. The plane was disgusting and smelled like dirty diapers. Everything was sticky and gross. I had to throw out the clothes I was wearing on the plane afterwards. I cannot believe the inconsistency. Never again will I fly Spirit."

Pros: "Nothing!"
Cons: "They didn't let us know it was cancelled after 4 hours of waiting due to bad weather even though all the other flights were taking off."

Pros: "I like the cost for the flight and everyone was very nice."
Cons: "I did not like that there was a big delay in the departure of the fight, I did not get to my destination until very late; this caused me to miss several activities planned for my granddaughter's graduation. I would have liked for my bag to fly at a lower cost as well."

Pros: "Everything was pretty good. Plane was clean, boarding was fine. I think if you know going in, there are no extras, then you'll be perfectly content. Also, there was more room than expected so that was nice."
Cons: "I have to say the crews going there and back could use a little more professionalism and customer service training. I don't wan't to blanket criticize all of them because I didn't come into contact with everyone of them as much as others, but I was put off by the flight attendants attitudes. They don't help as much as on other airlines and don't pass out food to everyone like on other airlines, so when I do order and pay for it, I expect a pleasant reaction, not to made feel like a burden."

Pros: "I did not know what to expect flying first time on Spirit but was pleasantly surprised at the efficiency and kindness of the employees."
Cons: "I was not pleased to find that the weight for a bag was 40 lbs and was charged $25 on top of the $40 bag fee for an overweight bag. This must have been in the fine print for I did not see it and packed my bag to be less than 50 lbs. The seats have no leg room and I found them to be restrictive for my 5'2" frame. They do not recline due to the space "saving" efforts of the airline. If you are looking for "cheap" remember to add on all the fees charged for bags, select seats, beverages before comparing to other airlines."

Pros: "Cheap. Ramen noodles. My personal carry on fit."
Cons: "EVERYTHING ELSE SUCKED!!! I actually opted to drive home 1100 miles rather than fly back."

Pros: "The intial price of the ticket was good."
Cons: "The seating is a tight squeeze. The plane was also very dirty. I'm happy i brought some wipes so I could wipe off my tray before using it. The lady who I checked in my bag at the ticket counter was absolutely rude. She ruined my mood for the rest of the day. Also by the time I finished paying for my bad there and back I could of paid for a nicer flight. I know better for next time."

Pros: "that it was on time"

Pros: "Boarding was fast and easy"
Cons: "Flight was delayed as always and the lines were astronomical to check a bag and print a boarding pass. Something that costs way too much money to be such a hassle."
