Pros: "The delta checkin desk were exceptional."
Cons: "N/a"

Cons: "Great crew!"

Pros: "Free entertainment"

Cons: "You shouldn't schedule a flight for a plane that is due to have scheduled maintenance. It's not like this should come as a surprise to you. Also, there was at least one over-served passenger on board who became loud and obnoxious, shouting obscenities."

Pros: "The crew was great and the seat was good"
Cons: "Our flight was 3 hours delayed"

Pros: "the video controller in the headrest of the seat ahead of me. you could see the flight pattern, speed, temperature outside and other specs, which were interesting."
Cons: "once again, the delta crew does not maintain their planes properly. during the taxi stage to get to the airway to lift off, there was a horrendous growling sound coming from the plane............seems like their hydraulic system is not maintained very well at all and it made a howling sound throughout the plane all the way to take off! we were wondering if there was something wrong with the plane."

Cons: "Good"

Pros: "Great Service and flight was without problems or delays. Arrived on time ."

Pros: "The plane and entertainment system was good. The cabin crew was a little slow. But all in all it was a good flight."

Pros: "Nothing."
Cons: "Well for one my seat was broken. At the beginning of the flight they said “there are meals for purchase available” when i asked for one they said they were all out but then gave out to other customers. Their attitudes were horrible."

Pros: "Smooth and comfortable flight."

Pros: "The movies"

Pros: "Cabin crew super helpful & friendly. The food was great - all snacks & meals were well prepared and had great flavor, I’m not saying it’s a 5 star restaurant, but I was wasn’t expecting the quality we received. Great job! Impressed by Delta service."
Cons: "Traveling is always a challenge - abundance of patience required! We traveled from Dallas, Atlanta, Amsterdam, to Rome & back. Every country had a little different process for boarding and getting around - most had friendly staff, on point, helping clueless, stressed, & frustrated travelers. I was really disappointed in Atlanta, not a very welcoming or helpful spirit for visitors to US - not all (80% were awesome), mainly those trying to greet and direct through customs. Most hate the arrogant America anyway, don’t make it worse - put your best people on the front lines to help with international relations & show why the US is the best. Put those that don’t want to be here loading bags out back! Sorry for the lecture, but this is any business!"

Cons: "Turbulence but no one can help that"

Cons: "poor hospitality by cabin crews cabin crews are very stingy in providing drinks"

Cons: "Not much- pretty great flight"

Pros: "delayed flight by Skywest or West jet - Delta subsidiary / affiliate. it’s the 2nd flight in a row that’s delayed. but much better than American Airlines."
Cons: "Flight delays. At least flight was not cancelled. Boarding staff & flight crew were awesome and entertainment was superb."

Cons: "Delay was over an hour"

Pros: "Roomier than a lot of airplanes."
Cons: "Bumpy ride. Nobody's fault."

Pros: "Entertainment system, snacks and friendly crew members"
Cons: "Serious delays on flight. It was very tiring and became an all day affair."

Pros: "Seats were spacious"
Cons: "No entertainment, snacks were bad and plane was old."

Pros: "20 minutes ahead of schedule"

Cons: "They said it was late because of a tire issue that was fixed in Salt Lake causing a late departure on a round trip SLC-Burbank. It arrived back to Salt Lake late causing the Dallas flight to leave late. I got a message at 6:24 pm regarding the late departure for the 8:15 pm flight to Dallas. They knew this info hours before. It should have been communicated sooner"

Pros: "Everything was great"

Pros: "I liked the legroom and the seat"
Cons: "No entertainment screen, no real food, I don’t care how long the trip is, I got first class, I expect first class service."

Cons: "Turbulence"

Pros: "I appreciated that Delta was on time and prompt about getting passengers onboard. I appreciated that the stewardess was very courteous. I appreciated that there was no delay."
Cons: "There was nothing that I did not like. I had a previous bad experience with another airline that canceled my flight three days in a row. So I was very appreciative of the fact that Delta had available flights for me to leave."

Pros: "-forgot to charge me for wine"
Cons: "-chair was broken -tray was broken -had to spend $33 for wifi that didn't even work -didn't have everything they say they offer to guests on the flight"

Cons: "No complaints!"

Pros: "on time meet all my expectations"
Cons: "I believe it is time for WI-FI to be complimentary in flights. It is far too expensive and feels like price gauging"

Pros: "Departing on time and clean"
Cons: "There was no screens, all the other airlines have screens, but that wasn't my problem and I got coloring book and crayons for me daughter, so she can play with them, but my issue was that when they gave snack to everyone and I didn't get anything and then I told the other flight attendant that I didn't get my snack and still she didn't get it, she said she was going to get it and didn't come back :(( I was really disappointed with that, they r old and forget things, so our line 19 nobody got anything .. i like delta was I wasn't happy this time with it"

Cons: "Late"

Pros: "Very courteous staff. Legeoom not too bad."
Cons: "Delay."

Pros: "Service in the flight !!"

Pros: "Good seats and very clear"

Cons: "Gate agent was cold rude and incompetent"

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: "With Covid they could hand out a bag containing water and a snack."

Pros: "Entertainment on seats"
Cons: "I sat in seat 12A- the window was so hot it was burning my arm and I was extremely hot. Not sure if it’s from the engine heat or sun but it’s probably a mechanical issue that the 737 should address. Horribly uncomfortable trip."

Cons: "The entertainment center at my seat was malfunctioning. Movies were starting passed the beginning and the system was crashing."

Cons: "Boarding is so disorganized. Really Group 9 is just a way to make the passengers wish they had chosen a different airline."

Cons: "Every seat sold. No social distancing. Mask rule not enforced."

Pros: "The seats were comfortable and it was easy to catch a quick nap."
Cons: "I wasn't offered any type of sanitation wipes like I was on my way departure. The airport in Mississippi disnt offer any type of sanitation such as hand sanitizer or a reputable substitute. Sure their were bathrooms, but that's very inconvenient to have to use every time you touch something."

Pros: "On time"
Cons: "Some social distance inside the plain would’ve great"

Cons: "Smooth and enjoyable trip unlike the second leg to Aspen"

Cons: "They need to stop selling the flights at full capacity"

Cons: "It being on time"

Cons: "All seats were booked, no covid-19 social distancing"

Pros: "Horrible seats"

Pros: "Great crew"
Cons: "Snacks"

Pros: "Travel is becoming a pain ... what’s new?"
Cons: "Just the way travel has become —loathsome"

Pros: "Entertainment Screen in the seat back in front of me"
Cons: "Deplaning. On one of my other flights this week they released us 3 rows at a time to limit social distancing. Thought that was going to be the norm but I guess not."

Cons: "Accommodates"

Cons: "First time wearing face mask all the time. It was okay."

Cons: "Everything"

Pros: "Timely and efficient"
Cons: "Seats are really small"

Pros: "Easy"
Cons: "All was good."

Cons: "Great"

Cons: "No food or beverage service during covid-19"

Cons: "Social distancing"

Pros: "Efficient"

Pros: "Crew was very accommodating but all three of us passengers were very close together, Thank goodness we were all considerate of the other."
Cons: ", Thank goodness we were all considerate of the other.Just need a little more elbow room for a comfortable flight."

Cons: "INTERNET is difficult to figure out in these AA flights"

Pros: "We finally got here."
Cons: "Communication about the delay , which gate we were leaving from, having an entertainment system that worked (they said I could use my device with the app downloaded, but it did not work, I kept getting an error)."

Pros: "Nothing"
Cons: "The flight boarded twenty minutes late despite the plane being at the gate early scheduled departure. Baggage took another forty minutes to load. Then they decided there we were overweight (data that should be known before the cargo was loaded) and off loaded two people. Then after another delay they realised that off loading people meant off loading their baggagge, total delay nearly 2 hours The hedset socket on the entertainment system did not work The USB port did not work THey ran out of food after serving three rows, loaded four sandwiches, no wraps and 2 cheese plates for a full evening flight that was over 5 hours in duration including the delays."

Pros: "NA"
Cons: "Multiple delayed flights leading to short connection time. Despite meeting stated time, denied entry and surprises that my ticket was changed with no effort to correct said error at the gate despite adequate time prior to take off."

Cons: "Entertainment is becoming too complicated for us old heads. Food, I still resent having to pay for something that is ed to be included in my fare."

Pros: "Must wider seats on this aircraft"
Cons: "Inflight monitor broken"

Pros: "Great films and tasty food"
Cons: "Had to run to gate after two buses to reach correct terminal. Saw info that flight was closing. Held up at gate due to confusion with my boarding pass. Limited leg room on flight. End of flight huge queues at Dallas airport for security. After a long flight a passenger does not need to be corralled through excessively long winding lines."

Pros: "I had a connection flight to JFK I came before the time about 15 min and crew saw me but she told me, sorry someone took your seats I lost around 4000$. This happened at Dallas airport."

Cons: "On time"

Pros: "The flight was on time. It was smooth and we had absolutely no problems"

Pros: "I like the in-flight attendants as they are courteous even though it was late night flight. I cannot complain at all."
Cons: "Gate agent refused to try to put my 9-year-old son to sit next to me. She said "It's full flight" right out of the bat. Well, even if that's the fact of the matter, at least, be kind in responding to customer's inquiry. My son was seated across the isle, same row, but in reality the row was not even straight. And as a little boy, he cannot sleep straight and he has to lean to a stranger's shoulder? Thankfully I got a nice gent who should have sat next to him who were so kind to exchange seat with me. It's all in the attitude.... hopefully my attitude is not as bad :-) But maybe the gate agent was so tired for it was the last flight from ONT, at 1 AM. Bless her heart! Thank you though for your help to get the plane leave on time.!"

Pros: "We arrived safely."
Cons: "I don’t like having to pay for luggage or upgraded seats, WiFi. All money makers. Wish every airline could be like southwest."

Pros: "The staff at Ontario International was very helpful."
Cons: "No real complaint of the flight or staff. Next time I will upgrade my seating."

Pros: "Everyone was courteous and professional"

Cons: "Everything was great"

Pros: "Very friendly, constantly hard working crew. They didn't stop moving through the cabin for the whole flight. Swift boarding."
Cons: "Extremely poor food. Airline food is rarely enjoyable but I had two mouthfuls of my pasta and left the rest even though I was hungry. Dreadful "entertainment " system. 4 tiny screens over the centre row is seats showed the in flight movies. This on a transatlantic flight. What decade are American Airlines in?! The fleet look like they date back to the '90's at best!!"

Cons: "The plane never cooled off for the entire flight"

Pros: "smooth check in and boarding etc"
Cons: "Wifi wasn't working so no entertainment"

Pros: "Everything was great to me"
Cons: "The flight was packed"

"Given how many delays and cancellations other airlines are having, I was very pleased with both flights of my trip being on time, easy to check-in & board."

"Great trip, excellent price! No entertainment on board which is typical for this short flight. I did enjoy the option to purchase snacks."

"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: "Boarding was easy!"
Cons: "Customer service w crew very rude and extremely inappropriate"

Pros: "Fast and easy flight"
Cons: "No sign at the boarding gate what the destination of the flight was - sometimes gates change I couldn’t easily confirm that I was at the correct gate"

Cons: "$4 for a bottle of water, cheap thin uncomfortable seats, tiny space to sit in and the girls at the desk are rude and not helpful! If you want packed planes with no space and thin uncomfortable seats and no drinks or snacks definitely fly here"

Pros: "Seat was average."
Cons: "If frontier was offering drinks and snacks again"

Pros: "The crew was reassuring when we were running to board and helped my husband, who had trouble walking."

Cons: "Seats are very uncomfortable. I was charged for my personal bag"

Cons: "Never left been waiting since 6 am for an alternate flight with no luck being charged for carry-on n I have no money not even to eat and I gotta be here til 6 pm"

Pros: "Really nice crew, I loved my seat assignment, Swift and easy boarding."
Cons: "Comfier seats"

Pros: "Crew was awesome ! The flight crew I would fly with anywhere, anytime. No mucking around ,get in , buckle up, we’re outta here . I love that ."
Cons: "I’m 6’2” , any vehicle other than my R1 is just not super comfortable. Even my truck and i love my truck . But anything over 2 hours starts wearing on my long legs . Thats my issue . Nothing any airline can do for that . I prob need to opt for 1st class next time n see ."

Pros: "I made it safely to and from my destination."
Cons: "The seats are very uncomfortable, lack padding and back support."

Pros: "Non stop"
Cons: "Seats suck"

Pros: "Nothing. I almost missed my brothers funeral and my wife DID miss because they canceled the flight and never let us know!!"
Cons: "Abominable customer service. No flight no communication"

Cons: "3 lbs over on luggage wasn’t an issue leaving but return made big deal and said she gets audited and can be a couple of lbs overweight. Wanted $75. So we threw away some liquids and dispersed some closed into carryons. Really stupid. Seats super small uncomfortable always have their hand out for payment for everything. Not eager to fly frontier ever again."

Cons: "Plane was scheduled to depart at 8:20 pm it was then delayed until 8:58 pm due to weather. We all boarded the plane and were ready for take off when a maintenance issue was discovered. We all deplaned and we’re told we would be put on a new plane arriving from Seattle set to depart at 11:30 pm. This departure time was delayed until 1:35 am and then 2:35 am because the captain had timed out and we would need to wait for a new pilot. Also due to the first delay everything was coded as “weather” and customer service was unable to give hotel rooms. This miscommunication between corporate and passengers and the late night created lots of frustration. Instead of being helpful or honest customer service called security on the disgruntled passengers. I heard no threats of violence just elevated voices. At midnight Frontier began handing out meal vouchers (15 dollars to McDonald’s) as a way to increase morale. I finally gave up and requested a refund, got a hotel, and a new flight on a different airline (all Frontier flights the next day were sold out). When I asked what would happen to my checked luggage they said it would be sent to Dallas (my destination) or I could pay for it to be sent back to Denver. The flight and my luggage arrived in Dallas at 5:30 am. Paid $400 for Southwest flight the next day (flying into different Dallas airport away from my parked car and luggage) just for the guaranteed service."

Pros: "So you got me from point A to point B."
Cons: "Uncomfortable seats. Overpriced fees for carry on luggage."

Cons: "Flight to SAT was cancelled and they put me in this one to AUS next day, Instead of SAT."

Pros: "Everything well"

Pros: "2.5 hours is long enough to get thirsty, a cup of water would have been nice."

Pros: "How quick the flight was"
Cons: "How long to unbord"

Pros: "That we finally made it to our destination."
Cons: "8 hour delay. Very poor communication the entire time. Made us sit in plane for another hour of mechanical issues and never updated us why- this was after sitting for 7 hours in the airport!"

Pros: "the beginning price - maybe?"
Cons: "I got to the airport in Dallas 2 hours before my 6:55 flight, and at that very moment, received a text that the flight was delayed 3 hours. At that time, there was NO ONE at the Frontier check in to explain what was going on. I understand there was excessive wind in Denver, but there should have at least been a Frontier representative at the gate in Dallas. On my way home, again the flight was delayed by an hour because of something on a previous leg. Because of this, I am going to go with any other airline first. I think Frontier should either co-op with other airlines to get people to their destinations on time or have more planes.......or AT LEAST have someone at the gate to offer next day service or a voucher or a free snack or something. I also do not like the whole A LA CARTE theme with this airline and Spirit Air. I do not like that I was going to be charged for a coffee or a coke. The whole thing is too confusing, and I am going to pay more for an American, United or Southwest flight next time."

Pros: "This flight-my return flight left on time. My flight to Denver was delayed 2 hrs. No one at the desk said anything until it was time to board, then they let us know of the 2 hr delay. Disorganized!"
Cons: "Disorganized and nickle & dimed ! Carry on's cost, drinks in flight cost, can't select seats until you check in.....as a whole-not customer friendly. Won't fly Frontier again."

Pros: "The crew on my flight from Dallas to Denver did nothing about the obnoxious children (6 & 9yrs old) behind me who kept screaming, yelling & kicking my seat & the one next to me. The little boy behind my neighbor stood up & hit the man on the head."
Cons: "While waiting on my flight in Denver to go back to Dallas they changed gates on at least 5 different flights & it was very confusing watching groups of 50-100 passengers moving back & forth. This all happened in about 15min & my flight was called to board during all this chaos but because the woman making the announcements did not speak very good English I along with several others missed our flights. When i went to customer service to rebook my flight they tried to charge me $100 to rebook!!!!! Other airlines will try to book you on the next available flight thru another airline. Frontier told me the next available was 24hrs later, same time the next day. I was supposed to be back at work the next day. So i ended up spending $150 on a hotel room that i couldn't really afford. I WILL NOT FLY WITH FRONTIER AGAIN."

Pros: "I like that the seats are thinner without a lot of padding. It gives more leg room. I like that my knees aren't hitting that seat in front of me. That crew was very nice."
Cons: "I don't like having to pay extra for my luggage. One bag should always be free and extra bags should be paid for. Paying for water is bad too. Water is cheap. People would buy a snack if they get free water. The fold down tray is also too small."

Pros: "There were quiet babies on the flight."
Cons: "It took longer than usual to board and the staff kept going back and forth about going through the safety proceedures."

Pros: "The no-frills (cheap) pricing."
Cons: "We had about a 3 hour delay with no explanation. The tickets told us to be there for boarding at the normal time though, so we were essentially threatened with missing the flight and had to hang out in the airport for several hours. The seats don't lie back at all, and the airline is very basic. Then again, you get what you pay for and we were expecting that."

Cons: "my flight out was delayed for 3 hours and check in had nearly 100-150 people in line waiting. I missed an important interview because of this delay."

Cons: "I paid for seat selection to have 2 seats by ourselves but Frontier changed the type of plane and it changed the seats to an aisle and a middle seat, exactly what I was trying to avoid. The flight attendant said I would have to talk to the gate agent but we had already boarded so of course that was impossible."

Pros: "Price, a non-stop route at a good times, friendly attendants and pilot."
Cons: "Paying extra for many things that are typically included (water, almost all seats, carry-ons), seats didn't recline and weren't comfortable if flight is long, no magazine to read."

Pros: "NOTHING NOT A DAMN THING"
Cons: "Almost $100 in hidden fees, having to pay for a seat, not getting a refund for ambiguous checkout jargon for a higher priced seat before I even checked out - so just changing my mind cost me money, sitting on a packed plane next to sick people isn't fun since I'm sick now, the planes are cheaper and made with charging customers money in mind. Overall, a completely horrible experience. Never again."

Cons: "THE FLIGHT KEPT BEING DELAYED ALL DAY AND THEN IT WAS CANCELLED. PASSENGERS HAD TO SECURE OTHER FLIGHTS TO THEIR DESTINATIONS. SOME EVEN MISSED IMPORTANT EVENTS LIKE FUNERALS, CRUISES APPOINTMENTS, ETC. I WAS A DAY LATE FOR MY EVENT. I THINK WE SHOULD HAVE BEEN TOLD IMMEDIATELY SO WE COULD HAVE MADE OTHER ARRANGEMENTS EARLIER. I WAS NOT A HAPPY CAMPER AND WILL NOT CONSIDER FLYING FRONTIER IN THE FUTURE!!!!!!!! THAT WAS MY FIRST AND LAST TIME TO PURCHASE TRANSPORTATION FROM FRONTIER AIRLINES."

Pros: "I was transported safely from point A to B. That's about it."
Cons: "Check-in was atrocious as we watched the clerks migrate from one crisis to the next, and no TSA pre-check. WAITING at every stage of the flight. You would think a one-way would be simple, but no. An hour at the departure terminal, delayed in-air, then sitting on the taxiway for an hour and a half at the destination, followed by more waiting at the gate. The pilot's excuses didn't help any, clearly trying to avoid an onboard riot for a flight in which we waited longer on the ground than we flew in the air. We checked the board afterward to see if any other airlines' flights were delayed--nope, only Frontier, every one. It's clear what happens. They pay the least possible expense for airport services, and are then the lowest priority at every stage of operations, resulting in delays at every phase of flight. The most frustrating flight I've ever had that didn't include actual incompetence or bad weather."

Pros: "had to wait over an hour for my bag to arrive at baggage claim. Horrible since it's cheaper to check than carry on. Can't depend on prompt service @DFW."

Pros: "The price and the actual flight was quick and the attendants were nice."
Cons: "Stephen Lucero 352936 discriminated against us at the gate. We were the only two people out of everyone boarding flight F9 129 to be pulled aside and asked to pay for a personal item that fit the size restrictions of the metal bag sizer outside the gate. We watched 50+ people walk onto the plane with not issues with multiple and bigger bags. We waited patiently but with frustration for an explanation and he could not offer one. When we asked what the problem was with us he threatened to not allow us to board whether or not we paid the bag fee. He did not take care of our unjust bag payment until 9:11 which was after the doors of the plane were to be closed. Aside from him being rude (which is a major understatement) paying for the bag wouldnt not have been an issue and it would have been justified had we not just flew into Denver two days before with the exact same bags. I was both embarrassed and humiliated and out of money for no reason."

Pros: "very efficient"
Cons: "seats wouldn't recline"

Pros: "Made the trip safe"
Cons: "Seats were uncomfortable."

Pros: "It was on time and smooth."
Cons: "Nothing, everything went well."

Cons: "I didn't like that you could not have a carry on and personal item but others did without paying."

Pros: "The low cost of the ticket although I thought that it was comical that we had to actually "buy" a seat after we had paid for the ticket itself. Shouldn't the ticket we purchase include the seat we sit in???"
Cons: "The two hour delays each way."

Pros: "Nothing."
Cons: "I didn't know I had to pay for a carry-on bag upon arrival. That's an additional $45 I didn't know about. There was a 4 hour delay and no clear explanation as to why. There was never an agent at the desk when people tried to ask. Our gate changed 3 times. Overall an awful experience and I will never be flying Frontier again."

Cons: "Charge $45+tax for ONE checked bag AND $40+tax for a CARRY ON!?! I'll be sharing this fact with Facebook, Twitter, YouTube, Instagram, FourSquare and Yelp. I'm never flying Frontier again and I'll be telling everyone I know to avoid them as well."

Pros: "On Friday, July 8, at DIA airport I waited almost an hour before someone took me to my gate A42 for Flight 122 supposedly departing at 8:10 and boarding at 7:35. Finally, I had to bring this to the attention of the ticket agent as I did not want to miss my flight. Noone came and the poor overworked worker took me at 7:45 -we did not arrive at the gate until 8 o'clock (luckily the TSA checkpoints were NOT busy) and had the flight been on time, I would probably have missed it. This gentleman asked repeatedly for assistance for over 40 minutes and no one came to his aid. I panicked and I want Corporate to know they need to hire adequate help so their customers are not treated like dirt. Once I boarded, the crew was fabulous! However, I am not happy about such a horrible experience. I deserve a refund or free return ticket for my inconvenience. I have flown other airlines and have never had such a negative experience with wheelchair assistance!!!"
Cons: "You all charge piece meal for everything; yet you don't hire enough people - I bet Corporate executives are getting their fair share!"

Pros: "cheap"
Cons: "no amenities"

Pros: "Nothing"
Cons: "Flight leaving Milwaukee was delayed due to technical problems. Got on the plane an hour late, sat on the plane for over an hour, had to get off the plane and wait in the terminal for 2 hours therefore missed my connecting flight and have not arrived at my final destination. There was nothing offered for the trouble or inconenience (snacks, drinks, etc.). I had to miss an important meeting and never want to fly Frontier again."

Pros: "The best part about the flight was when we landed in Dallas."
Cons: "The most uncomfortable flight I have ever been on. The seats were very hard and could not adjust. There was no information about the flight provided at any time during the flight except for when we were preparing to land. Compared to American Airlines (which we flew with on our way to Denver), Frontier has no comparison. There was absolutely no entertainment provided, and there were additional costs and fees at every turn. Not only do they charge for any and all refreshments, they also charge you to have a carry-on bag. The flight was also very very loud. The cabin rattled and roared for the entire hour and a half flight. We will not be flying Frontier again unless some major upgrades are made."

Cons: "When we booked the flight and there wasn't any disclosure about luggage expense and the check in personnel didn't tell us that it was cheaper to check all the bags, so we inadvertently paid for one bag at check-in but then paid a premium to pay for the additional carry on bags. NOT a good experience. This added an additional 120 dollars to our cheap fair. Full disclosure is always better"

Pros: "Delivery of promised services"
Cons: "Things out of anyone's control ie security"
