Pros: "Crew was nice, and pilot was helpful and got us there early."
Cons: "My screen for movies didn’t work, and the level of comfort was... almost none. I would’ve upgraded to more room, but for $55? When I’m already checking a bag for $30? On top of flight price?

Cons: "Sound of headphones was poor - staticky and garbled. It was hard to understand all conversations."
Pros: "The flight and crew were totally fine. I slept the whole time."
Cons: "There was not a single JetBlue employee at the Denver airport until exactly 2 hours before the flight. There were many passengers (upwards of 20 and many with small children) waiting around to check their bags and unable to access the food/bathroom/go through security. Everyone was confused and upset. While I understand that there are no flights for several hours prior to the late-night flight I was on, that does not mean that there is no need for an employee presence. Many people arrived multiple hours early because the most common destinations for Denver travelers are the mountain ski towns and the last departures of the shuttles that run from the mountains to the airport leave at 3:00pm. Therefore a large number of passengers arrive by 6:00pm for midnight flights and are left waiting in the check-in area until 10:00pm. The situation was made worse by the poor communication--there were signs saying that checkin was open only from 8:00am-11:00am, which left everyone very confused, given that we were on evening flights. There were many angry people sitting on the floor around the JetBlue counter."
Cons: "Flight was late taking off from Denver."
Pros: "Larger seats, friendly crew"
Cons: "NA"
Cons: "Airlines lost my baggage took 3 days to finally receive all of my luggage"

Pros: "the extra room"
Cons: "My flight was cancelled due to weather (understandable) but jet blues customer service desk was very unfriendly and not helpful"
Cons: "Dirty tray and seat area."
Cons: "Took my Mom's luggage and didn't check it through on the connecting flight. Then Said they would overnight it but didn't pay the charge for Saturday delivery. My 77 year old mother went without her things in Naples Florida after having a hurricane hit her house. I am appalled at the service."
Pros: "Always a fan of JetBlue - boarding process, flight crew, snacks, wifi, TVs. Great experience."
Pros: "Good leg room, TV on every seat. Easy boarding and unloading"
Pros: "Crew, tv"
Cons: "The last few times I have flown Jet Blue, delays and cancelled flights really upset my travels besides a 3 hour wait last week to take off from JFK. We all sat on the plane taxing for 2 hours, no fun."

Cons: "Very uncomfortable seats, hard to sleep in."
Pros: "Leg room wa nice. XM radio is great"
Cons: "No issues."
Pros: "The flight was smooth"
Cons: "Flight delayed for 1 and 30 minutes,rookie tow truck driver took him 20 min to dispatch aircraft,Pilots started the engines at the gate to make sure they start making money do to flight plan delayed and mechanical trouble shooting"
Pros: "Boarding seemed to be pretty efficient, especially compared to my most recent experiences on American. Flight was smooth (of course, airline doesn't have much to do with that). Got to my destination along with my luggage. Did not feel cramped on the plane and I was in a regular seat. Did not feel like I had to spend through the nose to just have a passable experience."
Cons: "Flight was almost 2 hours delayed. Plane felt a little shabby. Sometimes I found it hard to understand the flight attendant who did most of the announcements - she had an accent, which would have been fine, except that she either spoke too fast, or was mumbling. All that together, made it hard to understand her. Pilots never spoke to us. Not once."
Cons: "No decade coffee"
Pros: "With the 3 hr delay for weather, I appreciated the snack boxes and water provided at the gate."
Pros: "The snacks were fresh"
Cons: "Several delays, long wait time AFTER we were COMPLETELY boarded, non-communication between staff & passengers regarding WHY we sat on plane for at LEAST an HOUR after boarding, and flight personnel not double checking to make sure that all passengers had something to drink after the snacks were given. JetBlue needs to get it together!!! I will DEFINITELY avoid them in the future!!"
Pros: "I love JET BLUE...after travelling internationally with United and Ukrainian International Air...Jet blue was an absolute delight!. Love the WIFI and unlimited snacks! Great entertainment options and super friendly staff!"
Cons: "We ( I and my son 8 years old) flighted after 7 hours delaying . We were hungry and cold at airport . No body comlimented any thing and did not asked what we need . In 21 th centry , in USA , in domestic lines 7 hours .. than when we come jax airport there was no one of suitcases. One was demeged . It was worst flying experience . So that score"
Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Pros: "The crew had an amazing personality. They definitely enhanced my experience"
Cons: "Nothing"
Cons: "3 hours late!!!"
Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."
Pros: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."

Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."
Cons: "Choice of healthier snack"
Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."
Pros: "Good airframe."
Cons: "3+ hours delayed; didn't arrive until 3AM."
Cons: "Seats are so small. Flight was delayed."
Pros: "The entire crew was amazing they were professional friendly and accommodating"
Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"
Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."
Pros: "Professional appearance of flight staff accommodating and sincete"
Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."

Pros: "Food and entertainment was good"
Cons: "The bathroom I used was disgusting."
Pros: "The staff was polite and snacks were good (healthy options)."
Cons: "Nothing was terrible, but due to the short flights I assume they don’t worry about having planes with entertainment available."
Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."
Cons: "Engine problems-2 hour delay"
Pros: "Good flight crew"
Cons: "Delayed due to mechanical issues. For 3 hours. No offers for free drink or wi fi. When we finally land we were on the runway for half hour."
Pros: "Great people and crew early arrival nice passengers"
Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."
Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."
Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."
Pros: "Nothing"
Cons: "Let me just say that I’m a loyal Delta costumer until now. The flight attendants (the two women) were an absolute nightmare. They were so rude and condescending. I was carrying with me my service dog and a bag containing an expensive medication (it couldn’t go on the top bin). Despite being in the comfort class and having the seat next to me empty, we were tight for space. The flight attendants were unreasonable and forced me to put my medication on the top bin despite the fact I had told them it was extremely delicate, that it that to go upright, and that I needed to keep it with me. They did not listen and pressured me into giving them the medication. The medication could have easily gotten broken. Thankfully it didn’t but this is no way to treat a human being."
Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."
Pros: "Delta never used to be my first choice in airlines, but of my recent experience with them has been excellent. The people from the counter to the plane have been professional and courteous. This is why I will fly with them more frequently."
Pros: "Ran smoothly, typical flight, everything was as to be expected. Everyone was polite and courteous."
Cons: "Tight seats, boarding process was a bit lengthy, and we hit some turbulence (obviously beyond anyone's control). The pilot and crew handled it well."
Cons: "I was sitting in the last row and the bathroom smell was hard to deal with."
Pros: "Cabin service was coffee or water. Short flight tome of 45 minuted."
Cons: "Only offered cookies...would have liked nuts."
Pros: "Crew was the best!"
Cons: "I really dislike the snack boxes. Snacks need to be more like a small sandwich or grapes, cheese and nuts. Not all that packaged stuff."
Cons: "Late flt"
Pros: "depart and arrived on time"
Cons: "cramped in coach"
Cons: "I fly Delta quite often, and am usually pleased with their service, but the morning of June 23 was terrible. I got to the airport in Denver at 5:30 am for a 7:30 am flight to Atlanta, and the line to check a bag was about 40 people long. I waited 55minutes to check my bag, as they kept moving the ski priority people, and people in danger of missing their flight, to the head of the line. There were obviously not enough Delta workers on staff to process all the flights at that time."
Pros: "The moviea"
Cons: "The time of night"
Pros: "The flight attendants were so nice and accomadating. Even came by to refill our waters! I've never been on a flight with such friendly flight attendants!"
Cons: "Seats too close - I'm not that tall and my knees were jammed against the seat in front of me."
Pros: "Nothing"
Cons: "Everything. Boarded, day on the runway for nearly 3 hours, and then cancelled. No hotel allowance and all hotels near LGA full."
Pros: "Plane was clean and staff were friendly"
Cons: "The snack options were quite average"
Pros: "Flight attendants were lovely"
Cons: "Nothing"
Pros: "Excellent customer service. That doesn't seem to happen too often with airlines. Delta has been outstanding."
Cons: "No complaints."
Cons: "Easy boarding. On time departure and arrival. Great entertainment (watched Sports Center the whole way) so the flight seemed to be faster than it was."
Pros: "Flight took off on time and arrived about 30 minutes early."
Pros: "on time travel care in treating my visitors from Kenya Africa"
Pros: "The flights back to anchorage were much better than the flights out of anchorage. They were on time and everyone was very helpful."
Pros: "you still get a complimentary snack and drink"
Cons: "I had no room to move and my legs were stuck"
Pros: "The flight was not full ,so the flight attendants moved the passengers around to fill in spaces."
Cons: "Not a deal breaker for me, but some people like to sleep on airplanes. However, my seat did not recline and I know that can be a big deal for others."
Pros: "Crew was very nice and upbeat"
Cons: "Just a little more leg room would have been nice"
Cons: "More space to breath. More comfortable seats."
Pros: "Price was right and my golf clubs arrived without incident."
Cons: "Flight was delayed over 1 hour with little explanation."
Pros: "Good"
Pros: "For the price it's a good option. Just be aware of uncomfortable seats and cramped conditions ahead of a long flight."
Pros: "On time, nice new plane. No complaints at all."
Pros: "The price"
Cons: "They seem to have a hard time getting their flights out on time at the gate we’re told to be at..."
Pros: "The prices..."
Cons: "When boarded the plane then floors or seats were not cleaned from previous flight. Crumbs and degrees everywhere. Seats were not comfortable."
Pros: "Flight crew was excellent. Had a delay and Capt was very apologetic and personable. Made the best of a problem. Cabin crew were very good. Delay let me get some breakfast."
Cons: "1 hour delay because ground crew missed performing safety check. Had to deplane and then reboard."
Pros: "Checkin, bag check, boarding and arriving safe to my destination."
Cons: "Flight was 50 minutes late departing on a morning originating flight (scheduled departure time 6:10am). At departure time 20 people had to voluntarily move to the back of the aircraft due to a weight and balance problem. Then it took another 30+ minutes to get revised/new “paperwork”. Upon arrival in JAX (30 minutes late) we couldn’t deplane due to problems with the jetway, yet another additional delay."
Cons: "Medical emergency once on board, delayed the departure from Denver. While no fault of the airlline, as a passenger onboard, waiting in the back of the plane. Some type f overhead announcement being made would have alleviated any undue conversations between passengers, wonderment of departure delay."
Pros: "Nothing"
Cons: "Our flight was delayed by 2 1/2 hours and then we boarded & had to wait another hour. It messed up our plans & took 4 hours away from our quick trip to visit family. We got a $25 voucher but I really doubt we will ever use them."
Pros: "The plane was new and clean."
Cons: "I received a 2.5 hour delay notification at 4:45AM the day of departure. Upon arrival to the airport, bag drop was a mess of people and I was charged $15 additional to switch from pre-paid checked bag to carry on. Then the flight was delayed another 2.5 hours and there was no update as to cause or anticipated time of departure. I will do all I can to not fly Fontier in the future."
Cons: "I was a passenger on a Frontier flight from DIA to TMA on 5/13/2018. My luggage was checked and a tag indicating the bag was to go all the way to the final destination (there was a stop in St. Paul, Minnesota) was securely placed on the suitcase. However when I arrived at the Trenton airport my bag did not. There were no Frontier airlines agents on duty so I filled out a form given to me by one of the airport staff. When I checked the Frontier website today it said to fill out a Frontier Lost and Found report. Upon doing so I received an email saying finding a lost bag could take weeks and that after a month they consider the bag permanently lost. No offer or process was provided for compensation for lost bag or the items within. This is unacceptable! I had prescription medication in my bag that's not easily refilled."
Pros: "Great crew, easy boarding."
Cons: "Zero entertainment (no TVs, WiFi, inflight magazines or electrical outlets), very small tray tables, pretty uncomfortable seats"
Pros: "Great flight from start to finish. Had boarding passes, so easy, Quick luggage checkin, easy boarding, and easy, Quick luggage retrieval at end of flight."
Pros: "great flight crew the crew on the flight out to Denver was funny and kept even the safety instructions entertaining"
Cons: "no complaints"
Pros: "2 hour delay"
Cons: "Long wait"
Pros: "The flight from San Diego to Denver was great, the members of the crew were very friendly and helpful."
Cons: "The flight from Denver to Detroit was extremely late causing a huge delay in the entire process. Once we finally got ready to takeoff, we had to pull in yet again because there were passengers on the plan that weren't scheduled to go to Detroit.. all of these problems are somewhat understandable, but the crew FAILED TO EMPATHIZE WITH US AT ALL. They even made smart remarks about people going to the bathroom when we pulled back in... I feel some of them acted extremely unprofessional and I truly never want to fly with this company again."
Pros: "Nice crew."
Cons: "Our flight was supposed to leave at 6:40 PM but was bumped back until after 8 PM due to storms in the landing city however two other airlines in the same airport heading to the same city left on time."
Cons: "When you have to check in to get a lower baggage fee than if you check in at the ticket counter is totally unfair and a very poor business practice. If a friend hadn't told me that I needed to check in online, I would have preferred to check in at the counter. Not knowing what baggage prior to packing, I needed to change my carry-on to a checked bag. So I looked on the Internet for a customer service telephone number, which I found, but it's the wrong number.... Very frustrating!!!! At that point, I wished that I didn't book my flight with Frontier Airlines. Then I had to pay extra money to choose a seat, pay $2.00 for a drink . I definitely know that your customer service is bare bones, and the low price for a flight comes with annoying high price to pay. I will certainly think twice before flying with Frontier Airlines again."
Pros: "The price. Nothing super bad."
Cons: "Delay leaving due to a door sensor. Got in an hour late, which was annoying. Limited, expensive menu anyway, but was out of what I wanted (jerky). Biggest complaint is the seats not reclining-that's really uncomfortable for a 3 hour flight.2nd biggest complaint is that having to pay for my seat and 1 carry on feels like a bait and switch over the ticket price."
Pros: "Super professional, courteous, and helpful flight staff. Seat was uncomfortable, but it was a short flight, so I had a weird plastic bottle of wine and cared less."
Pros: "Both flights landed early and the pilot flew very smoothly (I tend to get air sick so I appreciated this). Easy to get on and off plane, no fuss. Great price ($250) to fly from DC to Denver, nonstop. Can't complain."
Cons: "The seats are very thin and feel like school bus seats, so it was a pretty uncomfortable couple of hours. Also, the check in at the kiosk is confusing and misleading. We were very prepared and did everything ahead of time (paid for our checked bag, knew that we'd have to pay for a cary on bag, etc.) but then when we checked in it asked us if we had a checked bag we needed to pay for. We doubted ourselves for a moment and almost paid for our bag, AGAIN, even though we had already done it. This payment should have shown up on our account and we should not have been asked about paying for our bag, that is confusing and misleading."
Cons: "You have to pay for hot tea, coffee when every other airline it's complimentary. Along with paying for carry on bags. Ridiculous!"
Pros: "check in crew were very pleasant and helpful, making the check in process very smooth despite multiple people, skis,etc. You are getting nickeled-and died- but I planned for that in advance, and despite that it was still a value compared to other airlines."
Cons: "seats are uncomfortable. If flights get cancelled (mine were not!), you are screwed because Frontier does not partner with other "sister" airlines, so you will have to wait a long time for a rescheduled flight or change airlines on your own dime"
Pros: "At least I did not have to wait on the tarmac for 4.5 hours like I did in Denver."
Cons: "the aft steward was a power-hungry tyrant. He kept telling me to get into my seat which was occupied. When that could not be resolved, he told me to get out of the aisle so others could board. I was in the penultimate row and the people in my row needed to move to the last row. So who was I blocking from boarding? Also, the flight was extremely turbulent and not one seat in the last 4 rows had barf bags. As I deplaned, it looked as if 10-12 others did not have them either - - good luck cleaning that plane. The seats are sized for 5-yr olds. And lastly - you stick it to passengers with all the non-disclosed fees."
Pros: "Thank God the flight was short!"
Cons: "Just about everything. The initial purchase of the plane tickets was what I thought was a deal. But this airline nickels and dimes you to death. We had to pay to check a bag. We had to pay for a soda. Only water is complimentry. We had to pay for the very uncomfortable seats we sat in. Really...what was the plane ticket for? By the way, if you wait to choose your seat/and check your bags...the price goes up. In the end it would have been cheaper to fly any other airlines. I'd never fly frontier again."
Cons: "All of the self check-in kiosks were down. Only two people were working the desks. The check-in line was out the door and it took hours to see a representative. Then, the barcode Frontier provided on the boarding pass did not scan with the TSA. I was denied access to screening and sent back up to Frontier's desks. If it wasn't for the generosity of several people in the line, I would have had to wait another several hours before seeing an agent. The inexpensive ticket is not worth it, especially considering one must pay for a carry on. Absolutely the worst experience I've ever had flying."
Pros: "There is no longer anything to like about Frontier"
Cons: "Charged bag fees at kiosk. Then told they couldn't take bags because of their cutoff time. Then told I could call customer service to get a refund. Then told by customer service they could not refund fees even though they would not provide the service. Oh...and they wanted $99 to book on the next flight. Even though the flight they wanted to book me on left the next night!"
Pros: "Check in and the security screen took an hour and a half, flight delayed an hour in beautiful weather. NO TSA Pre-Check at Frontier's home base."
Pros: "The fare from Denver to Portland Oregon was $83.00"
Cons: "The website didn't seem user friendly to me. I had to call Customer Service to be able to check in. I wasn't able to get my boarding pass on my smartphone very easily. My suitcase was 15 lbs over and I had to pay $75.00 on top of the initial $25.00. There were no complimentary drinks. And the flight was delayed and the personnel didn't know what was going on and wasn't able to inform us. The online seat assignment was confusing to figure out."
Pros: "Nothing."
Cons: "The flight was delayed for over 4 hours due to operational issues (not weather or maintenance). The gate representative didn't keep us informed of the issues and when he did, he was usually wrong. There is a surcharge for everything from carry-on fees to beverages on the plane. The plane itself was uncomfortable with uncushioned seats. Let's just say that if I had to choose between a Frontier flight and a Delta flight that was $400 more, I will choose the Delta. Same goes with any competitor. I will never fly Frontier again."
Cons: "The flight was over an hour delayed on the ground and then my luggage is still completely lost. The customer service has been absolutely terrible. I am in a city in which I do not live, with absolutely no clothes, toiletries, shoes etc and I have been on hold waiting to talk to someone about my missing bag for over 45 minutes. Frontier has absolutely no idea where my bag is, it is not in the place that I took off from and definitely not at my destination. This has been an absolute nightmare in which they offer you pathetic $50 to make up for the over $3500 I have in missing belongings."
Cons: "Seats - horribly uncomfortable, no recline Leg room - very tight unless you pay $50-$60 for stretch Hidden/extra costs - when I checked in almost all seats cost additional money; this is terrible for business travel and reimbursement purposes because it is considered an upgrade when really unless you take one of three middle seats at the very back of the plane, you have no choice but to pay. Carry-on fees are also ridiculous; it would be much better to be transparent and incorporate these costs into the ticket price. Food/drink - you offer no complimentary food or snack and when you buy something, there is a screen to add a tip - seriously?"
Cons: "It's very late to get a hotel and they didn't arrange anything for us. We get a credit for future flights and hotel reimbursement. But I'd rather not fly Frontier again!"
Pros: "We didn't have long layovers, and stayed at the same gate we came in on from Portland."
Cons: "disruptions while trying to get some sleep. although there was minimal food and drink service, the flight attendants went up and down the aisle a lot, collecting trash."
Pros: "I liked the crew, they were very personable and nice."
Cons: "Charging $40 per carry on? Are you kidding me?? We didn't budget for that and almost had to fly with no luggage. For this reason alone we are never taking another flight from Frontier. It's bad enough that Frontier charges for all baggage, but we had no idea when we bought the tickets off Kayak, that it would be an extra $130 for luggage. What a rip off. Then at the airport, the line to get a baggage ticket wasn't that long, but it took almost 45 minutes. Every time we fly Southwest or Delta, it takes only 10 minutes to get our baggage tagged and on our way to security. I was also unpleasantly surprised that even water costs $2. Other airlines give a free drink, but Frontier charges $2. Terrible. And the seats don't recline. In summary for areas to improve: don't charge me for carry on and don't charge me for water. I will also be looking for another online venue to buy my next tickets, we thought we were going to get a great deal (round trip tickets for two people for around $680) but instead will end up paying in the neighborhood of $885. Kayak let us down big time."
Pros: "In order to have cheap fares, Frontier charges fees for EVERYTHING. Carry-on luggage, anything besides water, etc. If you can fit everything you have into a small backpack and bring your own snacks, no big deal. If not, I'd recommend a different airline."
Pros: "Very low quality seats and definately not worth the extra money we paid for the so called more leg room No plug on under the seats and no wi-fi. 1.99 for a soda really? Too much mo way for baggage. Will not fly frontier again, you can get better seats and accommodations for the same price or cheaper on other airlines. Definately would choose United or American Airlines"
Cons: "The attendant woke me up after finally finding a position slumped over the tray (read above, no reclining seats) to ask about trash because we had a water bottle he was worried about us leaving. Very rude. Plus, as we saw a youngster dropping zip bags on the ground and that family wasn'tbeing eye balled by the staff. I wanted my overhead bad that I paid extra for, over my seat or a little in front of us so we didn't have to wait for the entire plane to empty before we could get it and the same attendant tried to push out back and was argumentative about it. He was one of the worst attendants in my experience."
Pros: "They held the plane an extra 15 to 20 minutes so that I could run through the entire Denver airport to make this flight due to my initial flight coming in to Denver, we sat on the runway for over an hour once we landed"
Pros: "Seats were comfortable and I arrived safely. Grateful for these aspects of my trip."
Cons: "Employees were rude. Inaccurate information about flight times provided before and during the flight. The hidden fees were ridiculous, such as $1.99 for seltzer water. Note that you cannot pay in cash for anything. Not so unusual, but a pain for since my debit card was lost. Because flight times were inaccurate, I had no time to buy food during my layover and wasn't able to purchase food on the flight. Overall, I would NOT choose to fly Frontier Airlines again unless absolutely necessary."
Pros: "Brand new A-321 (one week old) very smooth flight"
Cons: "The PA system on this one week old plane was way too loud. The long sales pitch for the Frontier credit card with 40,000 bonus miles was so loud that people were putting fingers in their ears. Otherwise excellent flight."
Cons: "Flight 33 minutes late leaving. Did not realize Frontier now charges for everything. My mistake but realized I could have flown on American for same price after all extras added to ticket by Frontiet. Not likely to ever fly on Frontier again."
Cons: "They charge for water. WATER. They charge for a carry on. The plane felt like it was going to fall apart. After an hour of turbulence, I started to feel sick but thankfully didn't have to throw up because there were no vomit bags. If you need a really cheap flight and are only bringing a purse, it would be a decent. But be prepared for rude people, discomfort, and turbulence. A misleading, unprofessional company."
Cons: "A 40 minute layover turned into a 5 hour layover in Denver. Frontier did not reimburse for the inconvenience, and sent a inadequate $50.00 coupon towards my next Frontier flight IF USED WITHIN 90 DAYS!! That was an insult, not a good faith gesture. They nickel and dime for everything, and take poor accountability for their errors."
Pros: "The pilot talked us through the turbulence and gave adequate and great information. The crew was polite and nice."
Cons: "Overall the food options didn't include an actual meal. That wasn't the specific flight's fault- more of an overall problem."
Pros: "Nothing"
Cons: "These flights are horrible- hard cramped seats, no services, not even a cup of coffee unless you pay extra. $40 to bring a carry on bag on the plane. Cost more than any other flight in the long run."
