Pros: "Flight did not take place because of cancelled return flight. the whole itinerary was cancelled."
Cons: "because of cancelled flight I had to schedule a new itinerary directly through American Airlines. The cost increased from $947.50 to $1,873 plus airport parking for 17 days."

Pros: "I had to sprint from customs in terminal D to skyrail then skyrail terminal A to gate 33, to make my flight. Could not see gate 33 but heard your staff shout out, "San Antonio"? Very grateful they saw me running or else I would have missed my flight."
Cons: "Being put in seat 30E when there was plenty of other seats available."

Pros: "I fflew Delta last Nov. Had meals movies dinner inks etc. American I am serv d beverages no meals and no movies. Getting ridiculous"

Pros: "We got to our destination safely, and American provided us with extra legroom seats."
Cons: "Service was curt and there was only phone-based entertainment."

Pros: "The crew was great"
Cons: "The seats were not comfortable and boarding was a pain. Not sure why you wouldn’t want to board from the back to front. Weather grounded us at our loading airport so we were stuck with the option of staying the flight or going in the lobby."

Pros: "The flight was what one would expect from a domestic airline. They did provide free movies/tv which was nice. It was one time to leave and on time to arrive."

Pros: "Attendants were so nice as kind"

Cons: "Me 6’ 200 lb sitting in middle seat next to somebody that needed 2 seats for self (pls understand I’m not unsensetive nor prejudice just stating a fact). I requested to sit in last row (of both sides of plane that were empty but attendant said sears reserved for attendants - 2)."

Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."

Pros: "Spacious seats"

Pros: "Mostly friendly staff and quick flight time."
Cons: "Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag."

Pros: "everything was on tyime"

Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."
Cons: "I've been spoiled by another airline's access to screens on the back of the headrest. I have my own hand held devices to entertain myself instead."

Cons: "Delayed a total of four hous!"

Pros: "crew was nice"
Cons: "never was told that a shuttle was needed to get from gate to actual aircraft. I almost missed my flight because of this."

Pros: "Flight was on time, staff was friendly and boarding was organized."
Cons: "I'm a small person (5'-2", 105lbs) and I didn't have room to breathe in that tiny little seat."

Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."

Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"

Pros: "Flight delayed which allowed us to make connection after long runway and customs delays. Crew friendly and helpful. Prompt cabin service. Baggage brought quickly in SAT. Clean plane. Power source."
Cons: "Local pickup at SAT is now devoted to taxi. Airport police rude. Most people picked up at 11PM and hard for cars to get to curb or see passenger due to taxi line. Both terminals terrible after several experiences in last couple months. SAT worst pickup experience that I see national and international travel. Obvious that cabs and air port police are the worst congestion problem I experience."

Pros: "Everything"
Cons: "Time was on point. And the flight was smooth. No complaints"

Cons: "No food or beverages for me. I slept comfortably on my flight"

Pros: "Staff and customer service were great"

Pros: "Nice airplane, it appeared pretty new. Everything was clean."
Cons: "My screen was out so I didn't get to use the new technology. I could see other people using it for maps and stuff. It looks neat."

Pros: "I don't know how airlines get away with all the stipulations and regualations they have in the buying process there is. Otho g I like about the scam artist they are"
Cons: "The fact they they can just make it a policy and then because the employees have to have a job and enforce it blows my mind. 200 dollar transfer fee plus the difference in the ticket when it's over two weeks in advance. You people are scam artist"

Pros: "You provide me with the best ticket prices and to me that was the the most important part of of the trip thx"
Cons: "The airlines charging for your luggage"

Pros: "Plenty of leg room no entertainment so I dozed."
Cons: "People stuffing oversized bags in overhead."

Pros: "Same"
Cons: "Same"

Pros: "One I love free sodies and two I love free sodies with a smile. I definitely got both with this flight crew."
Cons: "Not enough sodies and I couldn't smell my own farts."

Pros: "The crew was attentive friendly, energetic, educational and very helpful."

Pros: "Frankly there isn't much to say here. After 7 flights in 2 weeks there was only 1 flight with great staff that actually cared about the customers and looked like they enjoyed their job. The rest treated guests with indifference at best."
Cons: "Customer service is dreadful, the planes are so old they still have cigarette lighter charges in first (but of course no adapters), no food/snacks of any significance, and they seemingly cancel flights at a whim with basically no staff to help re-book the lines of guests that have been disrupted. I pity those who loose luggage AA baggage services are flooded with lost baggage they just don't care any more. Seriously its embarrassing how little they care about customer service."

Cons: "We were delayed for 4 hours, due to a mechanical issue. We were not given any forms of reimbursement. I would like a 500.00 voucher."

Pros: "Very rude and plane was hot. No air conditioning"

Pros: "All great."

Pros: "Everything was timely."
Cons: "No complaints"

Pros: "I was very pleased that the attendant gave me a free drink since I had a military ID. It was very kind of her."
Cons: "The flight was delayed multiple times. We were never informed as to why this was. It was very frustrating since I had a connecting flight into Tucson from Dallas. I got off the plane with twenty minutes to get to my next flight which was not in the same terminal. The plane was also incredibly hot while we waited to take off, I was beginning to become uneasy and nauseous."

Pros: "Window seat"
Cons: "Unorganized boarding. Not a smooth flight. Landing was questionable."

Pros: "Customer service, everyone was very polite, that makes a difference in your travel experience."
Cons: "Flight was an 1hr late arriving, this seems to be the trend for AA. For the past four weeks I have flown from Mami to San Antonio or Huston,and my flights have been more than an hour late. The last two flights I had a connecting flight and the connecting flight were hours late, hints that's why I paid more for a direct flight and it took of an hour after departure. I don't understand what the problem is, I fly AA frequently and never experienced such unreliable air service in regard to timeliness and no regard for clients time. Hopefully this helps, management should really look into the Texas leg, once again for the past month the flights haven't depart or arrived to its destination on time. Finally, I use AA frequently to travel overseas and I never experienced such lateness as my travel inside the USA (Texas especially). Sincerely, Mr harris"

Pros: "Zero of it"
Cons: "The fact they cancelled this flight for no reason, didn't contact me at all even though they had all of my information and than barely tried to re book me. They wanted me to take 3 connecting the flights the next day. And the next flight I was able to get on 24 hours later, I almost wasn't allowed to check in because they couldn't find my reservation."

Pros: "Airplanes are newer with onboard entertainment of all sorts for both adults and kids alike. Seats are comfortable Checking in was a very quick easy process"

Cons: "3 gate changes 2+ hours delayed leaving PHX"

Pros: "Very good service"

Pros: "nothing! entertainment should vd a one alos, not s friendly star system"
Cons: "over an hour wait. gate agents change in the middle of the wait time... no info was given s to what the mechanical problem. did di a very good job in communicating time! just totally screwed up."

Pros: "Quick boarding, departed on time, arrived early, good cabin communication"
Cons: "This is a very cramped commuter jet, just one flight attendant to serve entire plane, she came by once for drinks but not a second time"

Pros: "Efficient crew. It"
Cons: "It was good overall."

Pros: "the fact that the flight arrived on time without delay and the gates were easy to locate."
Cons: "How on earth did my i arrived lagos and only one out of my two bags showed up, i have to extend my stay in lagos and hoping my bag will come the next day, i have to pay $100 extra just to extend my one night hotel booking to two nights."

Pros: "Crew was extremely friendly."
Cons: "Temperature was way too warm."

Pros: "Good service, overall."
Cons: "You have to download United Airline's App in order to enjoy Inflight Entertainment. You could as well have it active in a webpage, I think."

Pros: "They accommodated my 6 hour layover by reducing it to 2!! Got me home 4hrs earlier. So grateful."

Pros: "Nothing"
Cons: "No meal on business, no free internet, no entertainment"

Pros: "The flight took off and landed on time."
Cons: "When I went to the gate in Houston to get my boarding pass for my second leg, the lady at the gate counter yelled at me because I didn't know my seat assignment even though I had already explained that I didn't know because I didn't have a boarding pass. On my original booking, I had chosen my seat to be a window, but when they rebooked me they put me in a middle seat even though there was a completely empty row in front of me. Then, to top everything off, they forced me me check my rollerboard carry-on because they said there was no more room on the plane, but when I got on I could see multiple spaces were still available. Another passenger and I were left to wait nearly 5 minutes on the jetway while the gate counter rep went to print our checked luggage tags. I asked the stewardess why I had to check mine even though there was plenty of space, and she said "it's hard to tell sometimes how much room we're going to have left." She also didn't offer any apology. All in all it was a terrible experience. I had to wait unnecessarily at various points of the travel process, had to endure a layover that was more than double what I had planned for, was forced to check my carry-on at the gate, and worst of all I missed a really important meeting. United obviously does not care at all about economy customers. Don't trust this airline! Book on Southwest or JetBlue - they actually care about customer retention!"

Pros: "smooth flight, good service"
Cons: "hold up to board family with 2 much luggage, overhead bins 2 small"

Pros: "The boarding process went smoothly and was on schedule."
Cons: "Overhead compartment filled up and it was hard funding space for my bag."

Cons: "The flight was delayed 3 times!"

Pros: "we were 10 minutes early to the gate"
Cons: "super cramped quarters, like touching legs to the next person the whole squirmy flight close... the plane was made for little people."

Pros: "Price was lowest for that date and itinerary."
Cons: "Feels like United is second class compared to other carriers. I purchased this for my Morher-n-Law who rarely flies was traveling by herself. there were 7 gate changes 3 day of. I Was very concerned if she would make it."

Pros: "Rain delayed our take off but most of the time was made up. No complaints!"
Cons: "Forced to check our carry on suitcase even though there was plenty of room above the seats."

Pros: "Comfort and great staff; smooth landing as well"
Cons: "N/A"

Pros: "Cleanliness,excellent customer service, flights on time!"

Pros: "Flight left on time and got in early."

Pros: "I loved how quickly we departed and arrived at each destination!"
Cons: "The boarding process was terrible. People forgetting to even stand in line for their boarding groups getting to cut ahead of those whose group is currently in the process of boarding. That should not be allowed. It's rude and disrespectful to other passengers/customers."

Pros: "Service was good"

Cons: "Late out of Stl. Missed flight out of Chicago"

Pros: "Flight was on time"

Pros: "The costumer service at Denver international airport was great."

Pros: "Attendant."

Cons: "no food or entertainment."

Pros: "On time. Quick boarding, very efficient."
Cons: "Stewardess was a little grumpy."

Cons: "Delayed over an hour in STL, which caused me to miss my connection to Hartford. United rebooked me on Delta. I had to go from STL to Newark (United) then to Detroit to Hartford (Delta). I was in airports for over 14 hours. I was 7 1/2 hours late leaving compared to my original schedule and arrived at the hotel the next day. I had 5.5 hours of sleep for an interview that I traveled for in Hartfford. Thanks United."

Pros: "The plane was slightly cramped, not as bad as my previous flight. Decent selection of adult beverages."
Cons: "Plane was present, crew was late by 2.5 hours, delayed my flight. I was scheduled to arrive around 2300, didn't get home until close to 0200. No wifi at all. I have always flown United, this was the worst experience thus far. We should be offered some type of discount for a future flight or a refund for this flight."

Pros: "On time!!"

Cons: "Flight cancelled due to mechanical, re-booked on Delta who had to re-book me on Alaska due to mechanical. An 8 hr trip turned to 22hrs."

Pros: "It was an overall good experience. I was flying home because of an emergency. I was able to get my preferred seat (at no extra cost) and the crew was very friendly."

Pros: "When we got to Chicago we didn't have a plane so we had to wait hours and then walked to another gate .. Wait for another hour and then they said we would not have anything to drink or eat in the flight"

Pros: "The attendant at the boarding counter was very helpful."
Cons: "As we are flying international and had a single itinerary, They didn't allow two checked in baggage's inspite of repeatedly explaining them that we have to take connecting flight which allows two checked in baggage's for each person."

Pros: "Nice staff"
Cons: "Horrible landing. They lost my luggage. Which I think my fees should be returned since I had to wait until 8 at night to receive it"

Pros: "Met a cute girl!"

Pros: "On time"

Cons: "Our original flight got cancelled out of St Louis, not once did the service agent tell me I could rebook my connecting flights myself on my phone. When I found out, I successfully rebooked my partner's flight and my reservation disappeared. Because of this I was on standby (along with 87) other people while my partner had a ticket."

Pros: "Was fast and smooth"

Pros: "First flight went great."

Pros: "The employees were incredibly cheerful and accommodating!"

Pros: "Low cost"
Cons: "Flight delays, little info passed to passengers"

Pros: "Very cheap"
Cons: "Very uncomfortable no elbow room or leg room and the chairs are hard."

Pros: "The staff that handled baggage was nice. Also, I liked that we made it safe."
Cons: "My flight was supposed to leave at 3:50...I got to the airport and went through security before I found out that my flight was delayed until 7:30. The flight kept getting pushed back. I waited 8 hours before the flight took off. There no outlets anywhere...leaving customers at a disadvantage because with our delay, our electronics were all almost dead or dead. There were no food options. We were supposed to get a voucher, and I have not received it. Lastly, after waiting over 8 HOuRS, we still had to pay for snack and drink. I was ripped off and will not be flying with Frontier again."

Pros: "Finally landing!"
Cons: "It felt like the rear end was going to come off the way it swayed after take off. The commode messed up causing a stench in the back of the plane, (where I was). The ride was very bumpy and the pilot intercom was hard to understand. We got delayed taking off and landing."

Pros: "The price."
Cons: "The space"

Pros: "My only good then was that I had wonderful passengers around me that were conversationalists who were entertaining and helpful!!"
Cons: "Can't you learn how to communicate faca to face with people? Let us know personally why we keep getting held up for take off, why we are being left in the dark, andehy you can't schedule more accurately! It doesn't help to fly somewhere if you miss the event you went to attend! Try compensating for our inconveniences for a change!!!!"

Pros: "I liked that the flight was not long"
Cons: "The seats were extremely uncomfortable"

Cons: "Loudness And over priced EVERYTHING"

Pros: "new jet. enough leg room (i'm male, 5-10). Overhead bins are normal size (can hold typical carry on), not the microscopic ones. Everything was on time."
Cons: "STL ticket counter was only staffed 2 hours before the flight -- which makes sense if they didn't have more flights, but the signs weren't big and complete enough for passengers to realize what was going on and how we would check our luggage. So we were standing around a bit confused. Once Frontier people showed up, it was fine. Also, coming back to STL, I had a 2 hr shuttle bus ride that was leaving 30 minutes after arrival, and although the plane arrived on time, the luggage didn't reach me until 37 minutes after, so I had to get a hotel room for the night. I don't know how luggage handling works, so maybe not Frontier's fault at all. 30 minutes isn't much time, but it was a direct flight, so I thought it would work."

Pros: "Very nice flight and crew. The gave me priority seat and boarding because I'm military as well as 2 free carryons."
Cons: "Only thing to make it better would've been wifi"

Pros: "Friendly on time service"
Cons: "Baggage fees"

Pros: "Getting seated near the front was nice."
Cons: "I had to bring my wedding dress and called ahead to make sure I had it figured out. Most airlines have a closet type storage area by the flight attendants and frontier does not. I was told over the phone I would have to buy a seat for my dress so I did that. Then when I went to the airport the lady was pretty rude and said that it was incorrect and it would be dumb to do that and I wasn't allowed. Then I had to pay an extra fee as well. Once to the gate we were delayed and the plane was there the entire time. We were scheduled to take off at 6:55 and boarded at 7. No reason for the delay and they didn't keep us updated. I was not very happy with Frontier this time."

Pros: "We landed safely"
Cons: "The flight crew was atrocious. They were rude when they spoke to us and when I asked for refreshments they turned around as if to get them for me and then the lady sitting next to my husband had to get their attention again to ask a second time if I could have water and Chex Mix so I could take my medicine. I have serious health conditions and I couldn't even get water without paying $3 a bottle. It is disgusting to me that we are charged for flight and then charged for Refreshments during that flight. Any other Airline who charges for a seat to take you to your destination includes at least drinks and nuts for free but not you."

Cons: "Flight From San Antonio to Philadephia, Late for 1 hours Flight from Philadelphia to San Antonio boarding on time, however we have to wait for 1 hour to take off"

Pros: "Terrible experience when we arrived at las vegasc in a cab. There was no one at the counter to assist us. We both needed wheelchairs to the gate. We had to walk inside to the counter. both of us use electric wheelchairs when we are at home. Walking is very difficult and Frontier was not there to assist us at the curb. This one experience ruined flying on your airline. Sandyntx"

Pros: "Flight departed and arrived on timr"
Cons: "Pricing structure. Misleading. Seats...horrific."

Pros: "Food/Entertainment NA"

Cons: "My flight was supposed to leave at 8:p.m. We left at 12:30 am. Hot in at. 2:00 am. Had to be at work at 7:00 am. Got home at 3:00 am instead of 10:00. How do you think people were. They were very disappointed Terrible airline"

Pros: "Great price, great service clean comfortable"
Cons: "N/A"

Pros: "I got where I was going to."
Cons: "One zone isn't even through the door and the next zone is called and all we do is stand in the very hot jetway for nearly 15 minutes. Being charged to pick our seat and for our luggage is ridiculous. It should be included in the price, if you have to raise the price then at least people would know better the true cost of their travel. Being charged for a drink! Having $1.99 put on a credit card! Wrong."

Cons: "You charge extra for everything."

Pros: "Cheap"
Cons: "EVERTYHING is an added on cost, no frills, cramped,"

Pros: "Friendly staff, large plane, cheap fare. I researched all the potential additional fees before my flight. Do your homework. It was a cheap, direct flight at a good time. I chose not to have a carry on, and I packed snacks for myself."

Cons: "Seats were extremely uncomfortable. Tiny tray tables."

Cons: "Your website says zone 1 first to board plane so I paid extra for seat in zone 1 - we were last to board No leg room - very uncomfortable- - didn't know I couldn't recline until I sat down Our main flight attendant was rude"

Pros: "Boarding was good. Flight crew was good."
Cons: "The space in front and sides of the seats are way too cramped. I will do whatever I can to book another airline rather then fly on a plane with so little "human" space."

Pros: "Crew was personable, and captain had a sense of humor. The flight was underbooked, so I had an entire row to myself, which was nice since there's very little elbow or leg room on frontier flights anymore."
Cons: "Somehow, the passenger across the aisle from from me was vaping marijuana. There was no flame, but the odor was unmistakable, and there was smoke. Crew either didn't see or chose to ignore. We landed 10 minutes late (I'm assuming because of snow at arrival destination) and waited another 15 minutes at the gate for the passenger boarding bridge to connect to the cabin."

Pros: "I was very pleased from check in to arrival. Seats are comfortable and appreciated being offered water. Very efficient crew and seemed dedicated to their job. Had no surprises since all the info was in the paperwork. Will fly Frontier next time also."

Pros: "New plastic molded seats on the Airbus are much more comfortable than the old style seats. Flight cost was a bargain."
Cons: "Although the cost to book the flight was cheap, the costs added up with seat booking fee plus bag fees plus a charge for any drinks except water. No more freebies."

Pros: "We love flying Southwest and the freedom of it has become our gold standard. HATED: Baggage fees Narrow seats Charges for CARRYONS...REALLY??? And the deal-breaker for us... That will be $1.99 for your (mediocre) cup of coffee, please. Oh, yes...and the flexibility of Southwests no cancellation penalty... PRICELESS! Thanks for asking."

Cons: "The seats were not very comfortable. You have to pay for carry-on and checked luggage. Then you have to pay for water. Might as well have use a different airline and payed a little more. The price of water and luggage would make up the difference."

Pros: "The price was good. Boarding was relatively painless and quick. The plane appeared to be new and was pretty clean. We were on time and even a little early."
Cons: "The woman behind the counter in St Louis was not friendly. I prefer to be able to use my TSA pre check status rather than wait in a security line for 30 minutes but for whatever reason Frontier does not offer that luxury."

Pros: "Your baggage policy is ridiculous and i might add a regressive fee inherently unfair. A single mother of 6 traveling to her mothers funeral will be hit harder by this than a business traveler. Many of us on the lower end of the income scale carry on to save what can be used on groceries pr heat. Yoir counter staff are also peremptory and rude. I will now factor these additional costs into your supposed fares you sjow online. Likely i will find other airlines are actually better deals. do you really think uoir cusyomers ste thos stupid? We know ur showing low fares and making it up w fees!"

Cons: "Delayed departure from 7AM to announced "possible" 12:30PM. Delay reportedly caused by "flight crew having timed-out" leaving our plane without a crew in Las Vegas. This very long delay made my trip unfeasible, forcing me to cancel my trip entirely, and my wife, having to shorten her stay in Florida by three days."

Cons: "seat fee; carry-on bag fee. When I buy tickets, I should have the right to know what my full cost will be, Sorry, I Am not an experienced flyer, but all the unknown add-on charges will make me loo a lot closer at ticket pricing on my next trip."

Pros: "NOTHING."
Cons: "The service was very poor. From the airport Frontier employees to the the flight attendants. There is an additional fee and charge for everything. My flight was delayed for 2 1/2 hours and upon boarding we still sat in the aircraft for an additional 45 min -1 hour wait! NEVER AGAIN."

Cons: "Cash not accepted for on flight beverages"

Pros: "Boarding and arrival were right on time."
Cons: "No complementary drink or snack on the flight. Baggage fees were much higher than industry average."

Cons: "Don't be fooled! Their flights seem cheap, until you take the flight and they charge you for every little thing- checked bags ($25 each), carry on bag($$35!!), seat ($16, and no, there are NO FREE seats. They even charge you for a soda on the flight- no complimentary soda/juice). By the time it was all said and done, it would have been cheaper to take almost any other airline."

Cons: "Flight was cancelled due to mechanical reasons and no alternative was provided."

Pros: "The seats were clean."
Cons: "The ticket counter did not open until 1 hour before my flight was supposed to board. Although I knew my flight was delayed, the agent at the counter said nothing. Additionally they charge for everything, from your bag to water on the flight. The price is cheap, but not worth the hustle or inconvenience."

Pros: "Boarding was quick"
Cons: "Messed up name on ticket had to call to have changed (would have been charged online to do so) Only saw flight attendant once This airline really nickel&dimes you. Tickets cheap but you pay for absolutely anything you may need. If you travel with absolutely nothing than this airline may be good for you. This is my second time with frontier had poor to okay experiences both times, will avoid this airline in the future."

Pros: "it was a direct flight. It was the only carrier with a direct flight. The plane arrived with no difficulty."
Cons: "The Frontier website was misleading. On check in it asked to pick a seat assignment, which were charged additional money for. I tried to undo the seat assignment (after I went and read their policy that it was optional.) So the website is fixed, that it can not be changed. So I called Frontier and after a 45 minute hold time was told options (seat assignment) can not be changed and I had to pay for it. This added $24 each way for a total of $48 additional charge. Also only a small carry on allowed. so that added an additional charge of $30. The seats don't recline even a little bit. as it was an Airbus and not a Boeing plane. not as comfortable as Boeing. Less padding in seat also."

Pros: "nothing"
Cons: "poor accommodations of the disabled rude staff No ADA accessibility over priced "a-la-carte" style of upcharging"

Pros: "Very disappointing - $45 to carry on a bag or $40 to check? Wish I would've paid the extra $100 to fly SW, Delta, United, ETC. The trays were 1/4 size of an iPad. You have to pay for a soda, water, or any beverage. The seats were small, uncomfortable, and didn't recline."

Pros: "Seating was comfortable and ticketing crew were very friendly!"
Cons: "Check-in process is cumbersome! No online boarding pass, the fact that you have to pay for Carry-on and pretty much any seat that you pick, brings the cost the on-par with others! Don't think I will fly frontier again."

Cons: "No snacks, not comfortable at all, overpriced, yhere wasn't a significant amount of savings because I paid to carry on my bag, no snacks and not comfortable!"

Pros: "There was a lot of things that i didn't like but the crew made me forget about all the bad things. Amazing crew and funny just maid everyone smile and laugh. Without this crew i think i would have hatted my flight but they made it worth it."

Pros: "Airport staff were nice, friendly and very apologetic."
Cons: "The flight was delayed 3 hours yet we were encouraged to arrive at our original time just in case the flight was moved up, which it wasn't, so it made for 5 long hours in the airport. Once on the plane the stewardess were less than friendly, at one point shhh'ing people."

Pros: "The best part is the direct flights to where I am going at decent prices. However, it comes at a cost."
Cons: "Wow. Each trip I take, they seem to have sat in a meeting and asked themselves, how can I make the passengers more uncomfortable. Charge for baggage? Check. Charge for a dedicated seat to ensure you aren't stuck in the middle? Check. Remove the recline feature from all seats? Check. The thing that really killed me though was their "new and improved" seat trays. Instead of the already too small tray on other airlines, they have cut the tray literally in half. All it could possibly hold is a drink. No laptop, no book...Really, were the savings that great over the life of the plane that this was a good buy? The only plus is you have a reason why you weren't able to get any work done on a plane..."
