"Not a lot of leg space but the flight attendants were very nice and comforting to ensure we had a good flight to our destination"

"Friendly staff at all levels. Efficient boarding, new clean plane, arrived 20 minutes early, lowest price available. No entertainment and food for purchase only. Great deal though for a short flight!"

Pros: "That I made it there in one piece."
Cons: "Not worth saving a couple dollars. Front tier airlines does not allow you to pick your seats before hand nor does it allow you to select baggage and the app, it is recessed for whatever reason. The seats are extremely tiny the tree table is so small you can barely fit an English muffin on it. There is no entertainment whatsoever, there is no Internet on the plane, and if you want anything to eat or drink besides water you will be paying for it. I’m sorry to say but flying on frontier was more like a punishment for me. I always fly American and wanted to save a few dollars what a mistake! With American most the planes that I have flown in have free movie entertainment and everybody seat the seats are comfortable And recline. And the snacks are free along with the soda. Please think twice before flying frontier."

Pros: "It was a safe flight"
Cons: "The flight was initially delayed 1 hour early in the day and notification was sent out. The flight was delayed again later in the day and the notification was sent out but not so promptly. An announcement was made at the gate that the flight was further delayed because the flight attendants had to clear customs. The flight attendants showed up about 30 minutes later, carrying bags of food from the resurants in the airport. I understand the flight attendants need to eat, but our flight was delayed prior to their landing and this added an additional delay. In total my flight was delayed about 2.5 hours."

Pros: "Flight was smooth. Company made good for their delay and provided a voucher for the inconvenience. Nice move by the airline."
Cons: "Delayed about 2 hours due to maintenance issue."

Pros: "It arrived on time."
Cons: "The plane was filthy."

Cons: "Frontier seats are minimally padded and do not recline. It's difficult to sit in them for more than a couple of hours. Our 3.5 hour flight turned into a 7 hour flight after being unable to land because of storm conditions, circling for over an hour, and being rerouted to land at another airport for refueling before finally heading to our destination. It has been a week and our backs are still bothering us. We flew Frontier because it looked cheaper but after paying for luggage, seats, and food we would have been way better off to have flown on Southwest. We will never fly Frontier again."

Pros: "Friendly staff, good seats."
Cons: "Baggage prices"

Pros: "Nothing was positive while using Frontier Airlines"
Cons: "Everything was pretty unpleasant: 1.) hidden baggage fees ($45 round trip would be one thing for a CHECKED BAG, but $90 collectively for the round trip is FRAUDULENT) Especially when most airlines don't charge for carry on bags or it's at least calculated in the final cost. At first when I booked this trip with FRONTIER $180 for my tickets looked like a decent deal, UNTIL I WAS TOLD AT THE COUNTER THAT I HAVE TO PAY $45 each way for a FRIGGIN CARRY ON BAG!! turning my reasonable and anticipated $180 trip turned into almost a $300 (NEARLY doubled my cost!) had I known I could have at least packed more into a checked bag for that price. 2.) my flight was delayed 4 hours on my outgoing flight, cutting into my personal time off and no compensation or even a kind gesture like a free McDonald's sandwich when you land...you guys really have poor quality and seem like you don't really care about the paying customer 3.) staff seemed clueless and didn't know how to answer customers questions as to why our flight was delayed!! 4.) mechanical issues with plane were the cause, or at least that's what the copilot or captain Just HAD TO MENTION TO US RIGHT BEFORE TAKEOFF, causing everyone to stir and raise eyebrows. 5.) to top off him mentioning the mechanical issues they were having with the plane the flight was rough..I've never been more tense or anxious on any of the other 30+ flights I've taken in my life. Pilot didn't seem to know how to handle turbulence."

Cons: "The flight attendant who presented the pre-flight info was snarky, made inappropriate remarks that she thought were funny and was unprofessional. This totally undermined my confidence in the crew. I think they should present that they take our safely seriously. I am unlikely to use this airline again."

Pros: "The crew had a great attitude and was able to make us laugh despite the fact that we were leaving late."
Cons: "The plane was dirty- there was balled up gum wrappers, food wrappers, and bites of food on the airplane floor. To make maters worse the carpet was already stained in multiple spots. My tray table also was dirty with sticky soda that had spilled on a prior flight. I was quite disgusted by the condition of the plane."

Cons: "Problem with the bathrooms had to sit on plane over hour waiting to be fixed. No refreshments served. Couldn't pay for bag on line so had to pay at checkin ..... not fair!"

Pros: "The price and schedule choice"
Cons: "They try to trick you into buying other things and speak in a condescending way on the website. There's no entertainment not even a magazine. The seats which are super ridiculously tight don't recline and there's no cushion for your head. You have to pay $3 for a soda and the batteries are so small you can barely fit which is great when there's pee all over the floor. The outbound flight was delayed over an hour with no explanation and perfect weather. When I asked for more water in the tiny cup, she poured it half way. I guess they are really trying to save money. Makes me wonder they took shortcuts on safety to save a few dimes."

Pros: "Nothing"
Cons: "All the the hidden fees from the baggage to seat selection. No snacks or drinks were provided unless bought individually and the cost for the flight wasn't any cheaper than our flight up on United, which included everything at no additional charge. The customer service was awful and though we arrived at the airport over an hour and a half early, we almost missed our flight because checking in a bag was chaos (despite having checked in online the day before). There were no forms of entertainment on the flight, not even airline magazines, which made for a very tedious 2.5 hour flight in less than relaxing seats."

Pros: "The seats were spacious"
Cons: "When I went to check-in for my flight and get my boarding pass, the Frontier employee at the counter asked if we had paid for carry-on bags online. We said no and she looked at our bags and said we were fine. When we got to the gate however, I was stopped and told that I needed to pay for my bag. I asked to speak to a supervisor. I explained that their employee at check-in told us we did not need to pay for a carry-on. They still forced me to pay AND tried to charge me the gate price of $60 which I refused to pay. If they were going to charge me for a carry-on, they should have made that clear at the ticket counter where I would have paid $45. They were incredibly rude about it and it seemed like a scam they had planned out to try and get $15 more out of passengers."

Pros: "None"
Cons: "The flight was delayed 5 hours, and we were offered a $100 voucher that would be emailed to us immediately after the flight takes off. I approached the desk to verify with an employee pre-boarding to ensure I will receive this voucher. She was annoyed with me from the start repeatedly saying it will be emailed after takeoff, which was NOT my question. My question was to verify that the email on file was correct. She had a very hard time getting this to her head. However, it has been over a week and I have yet to receive this voucher. Unless, I receive this voucher I will never recommend this airline."

Pros: "Not much."
Cons: "Frontier Airlines Lost My snowboard bag. No electronic system to track bags means you must rely on their human communication, and this is terrible. I can't believe they haven't invested in this type of tracking system....its 2017!!! Very bad customer service. No communication or mis communication on status of lost bag. Really they have no idea where it is. Promises to deliver lost bag at certain times and never do. Took time out of my day to stay home and wait for bag between 12pm - 6pm as they asked. Never showed up. Never called to say they wouldn't be showing up. They did this to me 3 times! It's 1 week later and I still don't have my bag. My ski trip was completely ruined. I've flown domestically, internationally, and I have never felt so uncared for as a customer. Tales of this terrible airline were told to me before I chose it. I can't stress this to any future potential customer. Choose another airline. Not worth it no matter how low the price is. Hidden baggage fees and terrible customer service will get you in the end!"

Pros: "Likely the most uncomfortable plane I've ever been on. Seats feature zero padding, the inability to recline, and a tray table the size of a DVD case. I'm 5' 9" 148 pounds, young and very healthy. I left the plane with a twisted up neck like I've never had before. I landed safely so I MUST be thankful for that, but if I was booking I would want to know this information. Since I'm the wiser now I will not book with Frontier again. Also it was an extra $90 for my CARRY ON round trip. It notified me it would be extra when I booked online but didn't specify how much. What a surprise. I spent more on the fees for the bag than I spent on the bag itself (and most of the contents for that matter)."

Cons: "The price was good, before you realized the price was a lie and they scam you by charging $45 to carry on or $40 to check a bag! That meant the overhead space was unused and they were just charging more just to be inconvenient. The plane was stripped barebones. The crew were rude, did not smile, and gave me attitude for hitting my elbow with the drink cart. They charge for even getting a soft drink. Nothing about the experience said "we're serving you." It's worse flying a more expensive airline because the rediculous bag fees make it just as expensive and even things that should be free like pleasant staff were lacking."

Pros: "O'hare airport."
Cons: "I was unable to print a boarding pass at one of the many kiosks - it informed me I needed to speak with a Frontier agent. The line for the agents was about 2 hours long, too long to wait to make the flight. After being told by a frontier employee that I'd just want to get in to the line to rebook on a later flight (9 hours later) I proceeded to speak with a momentarily vacant agent who, helpfully, printed and handed me my boarding pass. I arrived at the gate to a closed door and ended up needing to rebook anyway. I decided to just not go on the trip.... wasn't worth having to deal with Frontier 2 times in one day."

Pros: "It was SUPPOSED to be a round trip. I arrived at LAS an hour before departure, and tried a kiosk. It advised me that I needed to see an agent. I get in line. 19 minutes later, I am informed that even though the plane is still at the gate, I missed the 45 minute deadline,and cannot board. The agent will not help me to book another flight, but gives me a paper with an 800 # on it. I am told that all of the next days flights are sold out. I managed to get a $287 flight t 6 am the next day, on a different carrier. When I arrived at Ohare for the return leg, I was charged $40 , for my carryon. When I expressed my displeasure at the charge, I was told that Frontier was a low cost operation and should not be surprised that I would pay more for extras. My response to that is "When did customer service become an extra, for which I should be charged?" I have found your corporation to be an overpriced low service airline, a soulless company intent on squeezing every cent out of each transaction, while providing even less than the bare minimum to the sucker who buys a ticket."

Pros: "I really liked the brand new and updated Airplane. The fit and finish was quite nice and the electronics and lighting were nice."
Cons: "The crew was poorly trained in virtually all aspects of their duties. They had no coordination among themselves and ran around like a bunch of chickens with their heads cut off. One attendant yelled at a passenger at one point. They kept turning the lights on and off abruptly and made a HUGE deal about throwing away the trash because otherwise they will get stuck doing it all. The intercom system was also abused as the attendants made, at times foolish announcements, with a different attendant speaking almost each time. One would almost yell while another would speak very softly. The intercom system and speakers on this plane, particularly from the cockpit, when the captain spoke, sounded like it was from the Vietnam War era. For a brand new airplane, this was a disappointing shortcoming in the technology. We experienced excessive turbulance for the majority of the flight as well. I do not know if this is something the pilot is able to overcome but on this flight, it certainly was an issue as i almost had to vomit from all the very abrupt and excessive motion. I would not rate this as one of the better flights i have been on."

Cons: "Look like frontier is always late"

Pros: "I actually like that you cannot lean your seat back. It's too imposing on the passenger behind you."
Cons: "They charge extra for everything. Every seat has an extra charge except for the middle seats in the very back row. Once you've paid for your seat and for your carry-on bag(!), you've paid as much as you would have flying with Alaska, American, United, etc. There was no entertainment whatsoever on a 5 hour flight (not even for purchase) and no snack provide either. I believe there was food for purchase but I didn't even look at it. Also, they do not support TSA pre-check. This would have been something the representative I called should have informed me of but instead she told me she had updated my records. So in addition to the fee gouging, their staff are either uninformed or outright dishonest."

Pros: "Crew on the plane was super nice and cared for us."
Cons: "Check in process was HORRIBLE. I initially showed my military I.D in order to check into my flight. All U.S Navy service members that are attached to a ship have a sticker on their I.D that states their ship and department. The lady that was assisting me accused me for having a fraud military I.D as the sticker ONLY hides what branch I serve in. She accused me for hiding information on my I.D as she tried taking the sticker off as I need that sticker to get on and off my ship. I was also accused for not looking like my military I.D picture. That picture was taken during boot camp as my head was completly shaved and I had no facial hair. I obviously grew out my hair and had facial hair as I was in a leave status. I was not required to shave for the duration of my leave. She also asked why I was not in uniform. The lady assisting me failed to realized that active duty members do NOT have to be in uniform every second of their waking lives. She did not believe I was in the U.S Navy and was super disrespectful. I just gave her my Illinois I.D to avoid any other trouble. I'm not a confrontational person so I just tried to avoid creating a scene in front of everyone. She was not wearing a name tag so I called frontier to make a formal complaint. I will not be flying with frontier anymore. Thank you."

Pros: "The staff on the flight were very friendly"
Cons: "The takeoff time for the flight seemed to be delayed by people trying to fight over overhead carryon space. There isn't much the airline could do. I spoke with customer service on the phone multiple times on the flight regarding various issues. They were able to help on about half of them. Response time was extremely long and trying to get a hold of someone was nearly impossible (When through a bunch of prompts to discuss issues with a computer instead of a real person. Yes I tried pressing "0" every chance I could to be redirected)"

Cons: "After pushing the flight back twice, they then bumped the flight back up and changed the gate without making an announcement throughout the terminal. I also received a text notification indicating the flight was delayed, but not that it was moved up again and the gate had changed. They only called our names after it was too late and they would not allow us to board. They left seven people standing at the gate as they pulled away. The earliest they could rebook us was 2 days later. Book a budget airline, get budget service. Will happily pay more next time for a different airline."

Cons: "We landed in Denver and landed a little behind schedule. The flight was below average as the pilot was navigating in "bad" weather. It was not even raining. Once we landed the pilot continues to get on the radio to tell us we would be sitting for 10 minutes. After over an hour we finally moved to a gate. Now that we are over 1.5 hrs after our schedule time frontier took over another hour to get the bags to baggage claim. This is embarrassing for a company that is inflexible in changing flights, charges you to pick a seat, charges you to check a bag, and charges you to carry a bag on. They should return all their customers money from this flight I will not be flying frontier again."

Pros: "Boarding was quick."
Cons: "Flight delayed due to "changing of aircraft "- we taxied off the runway over an hour late. Nothing like getting to the airport early and then waiting even longer due to the airlines mistake. The plane was disgusting- food and crumbs all over the floor (not exaggerating). Add to that Frontiers extra charges ($40 for a carry-on and anywhere from $5-25 for choosing your seat) and no drink service (not even a water) offered to us- it was terrible. Thankful it was a short flight and we were safe but for what we paid and the delay factor l wish we would have just drove. While l now know to do my homework ahead of time, Kayak should list airlines that do not include at least a checked bag with the price."

Cons: "I've always been dedicated to Frontier but am quickly losing hope. They gave our gate away to another flight that was 3 hrs late. While boarding that flight, the gate attendant announced the Captain was on the wrong plane so passengers deplaned and started over. Our gate changed eventually. When arriving, our gate wasn't ready, and the crew had difficulty pulling in. We had a 2 hour delay with 40 minutes waiting for our baggage. Very poor communication. We found out more info on line than at gate. This was coming home. My story getting to Chicago on Frontier was as bad if not worse. Many other stories were being shared as well. Sad to see an airline that fought so hard to survive treat their loyal customers like this."

Pros: "The flights went fine, and were mostly on-time, just a little delay leaving Chicago because the incoming flight had to wait for a gate to open up"
Cons: "Frontier's customer service line is horrible, with no clear option to reach a person to ask questions of without hunting through every option. Also, they charged me to pick a seat, ANY seat, so what the hell am I paying for when I pay for a flight?! I also had to put my backpack under my seat, even though it was stated numerous times on their website that it would be too big, and I had to pay $40 to make it a carry-on, when there was no room in the overhead bins. Their customer service line AND website stated I could be charged up to DOUBLE that ($80) if I had to pay for it at the gate. I looked it up, and I would have payed less on at least two other carriers because of the extra charges. This is information that should CLEARLY be stated when listing the costs of a flight, not "covered" under "additional costs may apply" or some such legalese"

Pros: "Not much."
Cons: "The flight was delayed for over three hours. At destination (Seattle) the Link Rail system was closed and I had to pay $50 for taxi service. This was an unplanned expense. I can forgive issues with planes and reasonable delays but there was little or no concern about leaving passengers stranded at the airport. The $50 discount on a next flight with Frontier (which won't happen) is of little use. I would have appreciated some help with getting to my destination and room accommodations. Do you know how hard it is to make arrangements at 2:30am at the Seattle Airport. No food, no ride, and had to get someone to let me into my room early in the morning."

Pros: "Very efficient."
Cons: "No free beverage."

Pros: "Crew was amiable."
Cons: "Fees for carry on were hidden and expensive. Boarding called groups 1&2 immediately, the. 3&4 within 30 seconds. This was due to plane being delayed. In either case the boarding turned into a zoo."

Pros: "We arrived in Las Vegas 20 minutes early."
Cons: "1.) We sat on the runway in Vegas for 15 minutes waiting for a gate to open. 2.) They charged me to select a seat. 3.) They charged me to CARRY ON a bag ($45!) 4.) They don't participate in TSA Pre-check 5.) There was no organized line-up for each separate boarding group. 6.) I was seated next to a baby that screamed for 3 of the first 4 hours flight time w/o flight attendants doing anything to help the dumb-ass dad who neglected to bring a freaking binky w/him! I guess maybe I'm just spoiled by the FAR SUPERIOR service of Southwest Airlines. Last time I let someone else book my flight on another airline!"

Pros: "The room between seats in the cabin."
Cons: "Our flight was delayed 2 1/2 hrs. We were told we would be updated every 15 min. Not! Finally a plane was coming from 2 terminals away. It took over 45 min to get to our gate, with no updates every 15 min. Emails updating our flight status reached us as we were on board the airplane. Not helpful. We reached home at midnight when we had planned to be there by 9pm, in order to shop before Sunday. Even though we weren't in a time crunch to arrive, my time is obviously not valued by this airline. I will make every effort to NOT fly this airline in the future."

Pros: "The website when you try to check in online is deceptive. It seems as though all seats and carry on luggage cost extra money. They should change that."

Pros: "The pricing of the flight was great in comparison to other airlines, the flight was also on time and a bit early arriving to my destination. I did do my research prior to flying with frontier and noticed that many other travelers have complained about the added costs; the airlines website states that you have to pay ahead for baggage and carry-on's prior to arriving at the airport otherwise it'll be a lot more expensive there. I paid for luggage each way, no carry-on during this flight but did choose my seat ahead of time as well as I was traveling with my husband."
Cons: "The bathroom was not clean and smelled terrible - this should definitely be looked into as airplane restrooms are pretty gross already (also being pregnant, the smell was even worse). You don't get a complimentary snack/drink on the plane light other airlines but the ticket was about $100 cheaper than competitors so it wasn't anything to really complain about."

Cons: "Baggage drop lines were unbelievable. Foreign travelers were in the same line as domestic. There were only four agents to handle 100s of passengers. When I checked in online, to select a seat I had to pay an additional fee and then was also charged for my carry on bag which increased my fare by $68. In addition they do not participate in TSA precheck which further delayed my security process. Although I had allowed plenty of time (1 1/2 hours) to drop my bag and get through security by the time I got to my gate my flight was already boarding. Additionally you are charged for everything on the flight even water which for a 3 1/2 flight is ridiculous."

Pros: "Aircraft"
Cons: "Nothing"

Pros: "On board crew was very nice and were very entertaining."
Cons: "I've flown frontier before and I have never had a problem. Tried to check in for our flight 30min before it took off as we were running late. The rep who was working the desk (young female, approx. 20yrs old) gave us the worst guest service I have ever received. I did not understand why we could not check in, nor attempt to board our flight, although I understood it is our fault for running late. We did not need to check any bags as we were carrying them on. The woman behind the desk only kept saying you missed your flight and was very disrespectful when our friend tried to talk to her saying "I don't know why your even trying to talk to me, I told you I am done with you." I work in the guest service industry and have never been treated or talked to with such disrespect. I would have understood if she was apologetic and explained to us WHY we could not board or make our flight, compared to being rude and rolling her eyes constantly. I will not be flying frontier again I can avoid it."

Pros: "Nothing really."
Cons: "Frontier advertised cheaper fares but when all the nickel and diming is done (like the baggage fees, seating fees, in flight drink fees) your better off spending a little more up front with another airline than falling for their cheaper fares. They try to sell you 'a roomier seat' but delivery seats which reminds me of public transit. They don't recline and they also don't have a tray large enough to accommodate a laptop!! Hard plastic covered in vinyl with fancy stitching. Try sitting for 4 hours on that! Southwest is a much better choice."

Pros: "On time on the way out."
Cons: "Bought the ticket in Chicago because it was cheaper than flying out of Madison or Milwaukee. Even if I paid for a bus ticket from Madison to Chicago. When I went to check in it took 5 phone calls and 1 1/2 hours later. The reason for the call was the carry-on baggage charge which was astronomical and my question was is the $40 for round trip. Which it wasn't. Also, I was unaware of all the additional charges, seat, bottle water, soda etc. The biggest problem was no WI FI on board. I need to work while I was in the air for 4 hours. It took 5 phone calls because I couldn't understand the person trying to answrer my questions. I also couldn't check in because Frontier was not compatible with my IPad. Talk about getting frustrated. I had enough stress traveling for business. On the way back we were backing out to the runway heading to take off and the captain announced that he was turning around because a passage was vomiting due to overindulgence of alcohol. 45 minutes later finally backed out to take off. I barely made it to my bus. Thank god I can run fast. What a nightmare that didn't need to happen. It would have been way cheaper to fly out of Madison or Milwaukee. What really PMO was socking us traveler additional charge for so called peak time. WHO DO YOU THINK BAILED YOU OUT IN 2001? Your should be ashamed of yourselves."

Pros: "The crew was courteous and professional."
Cons: "After adding up all of the hidden fees with the "low cost" of the flight, it all came out to MORE than I would have paid if I had booked a flight with another carrier!. As ad DEPENDENT of an active duty military member, I NEVER have to pay for checked luggage, much less a carry on! Once I got over having to pay and additional $150 for luggage, I board the plane to find extremely uncomfortable seats with half of a tray table, all I could do was laugh. The joke was totally on me!!!! For a flight that was over 3 hours long, it was NOT WORTH ANY OF IT!!! I didn't do the research that I should have, and that is totally on me. Fool me once, but NEVER AGAIN."

Pros: "The crew."
Cons: "The crew was fine. At no time was I made aware during my booking that I would be charged for a carry on and or checked bag. The total cost added $205 each way for 4 passengers to my flight. I feel completely mislead. Customers also had to pay for water on the flight which was ludicrous. The cost of baggage went up ten dollars from what I was quoted when called customer service to inquire about the prices on preselected seat assignments the day before departure. The seats do not recline and are very uncomfortable. The flight was delayed by five hours and no food vouchers offered. I would not fly frontier again nor recommend to anyone."

Pros: "Frontier staff in SFO (San Francisco) friendlier to passengers than ORD (Chicago). Kept luggage at SFO for pickup when I arrived"
Cons: "Missed flight by 10 mins. Was able to check-in 1-hr before a domestic flight and get my boarding pass printed. However, the attendants were not interested in expediting me, and 4 other passengers going on the same flight, through security. Ultimately, 5 passengers with boarding passed missed their flight even though we had arrived to the airport and checked-in at an appropriate time! After the plane left, an attendant assisted a passenger to rebook their flight, but then left to go on break and left 3 of us stranded. Very few Frontier attendants available to help us. Had to pay $225 for another same day flight to SFO using American Airlines. Learning points: - hard deadline, need to be at gate 10 mins before departure time - lofty and esoteric reimbursement process - Frontier does not participate in TSA Pre-Check, so arrive 2 hours ahead of departure time for domestic flights - Frontier does not participate in other airline organizations, so unless you rebook with Frontier you are paying full price for the new ticket"

Pros: "Nothing"
Cons: "Everything. Frontier is awful and I will never fly with them again. They cancelled the flight for "weather" more than 12 hours in advance. By the time the flight was supposed to leave, flights were taking off from O'Hare without any problem. Next, they could not have been less cooperative in helping my find an alternative route to San Fran. After more than 2 hours of arguing with Frontier personnel, they magically found a way for me to get there via Denver. Finally, once I boarded the flight to Denver, the crew could not have been any less competent. I saw at least two instances where they had given away the seat of someone who had checked into the flight, then had to scramble to find them a new seat. Frontier is the worst."

Pros: "The boarding process was easy enough."
Cons: "The crew was absolutely clueless. Half way through the flight no less than 6 sleeping passengers were woken and shuffled about because they discovered two other passengers had seated themselves in the priority area. I understand the desire to ensure passengers are seated properly. However, it was ludicrous to wake 6 people who were not at fault for this error on their part. They should have been more vigilant at the start, or left the rest of us alone after the fact. Terrible understanding of customer service. Also, our flight arrived early, however, they didn't have the appropriate gate available. Poor planning as we knew we'd be early about half way through the flight. Would not fly again, not because of the disorganized gate business, however, there's a real lack of customer focus on this airline."

Pros: "I will never fly Frontier again. Poor customer service. Poor baggage handling. Poor timeliness of flight and baggage delivery. Poor communication of flight delays and baggage mix-ups. Understaffed. Undertrained. Poor seats, particularly considering I paid for the best. Inadequate compensation for 8+ hour delay and missing baggage for 3 days. After all the nickel and diming for seats, baggage (checked AND carry on) it would have cost me less to fly my preferred carrier and avoided every hassle, not to mention the inadequate compensation (again). Horrible, horrible experience."
