Airline reviews

Cons: "Baggage lost."

Cons: "I'm a tall person and there wasn't an option to get a seat with any extra leg room. Additionally, the gate staff were not helpful or informative about the flight and rushed when it was time to board."

Pros: "The free entertainment."
Cons: "Everything was great."

Pros: "Ease of boarding with the group numbers"

Cons: "The captain had the crew return to their seats during drink service due to turbulence. Despite the fact that there was 2 and half hours remaining in the flight and the turbulence was gone, they never returned to complete the drink service."

Pros: "Very courteous crew.pilot was amazing!! Landed in tough wind"
Cons: "Turbulence"

Cons: "Never knew flying domestically with a company named American would be so impossible. A true joke. Never had such difficulties traveling about. Super unsatisfiee and will not be traveling with them again. I urge everyone considering to purchase other airlines as well."

Pros: "The flight attendant was super super nice and helpful"
Cons: "Had to rush to catch this connecting flight. At boarding time, which we just made, the previous flight had just landed and people starting to deplane. All we would have wanted was an accurate announcement versus an unfriendly feeling from the gate agent"

Cons: "I hate American airlines. It is the WORST. We were held for almost 4 hours waiting for "maintenance call" then flight was cancelled. THEN it took two full hours to get back checked bags. By ths point it was 5 pm, had been at airport since 8:30 -- no food offered, no apologies, not even a glass of water. Of course, no flights back to US so I was stuck an extra day, completely messed up school and work. I THOUGHT I was booking with Iberia but it was a code share. I WILL NEVER fly American Airlines again!"

Pros: "."
Cons: "."

Cons: "The flight was cancelled. I didn't receive a refund or free hotel accommodations. I've been on flights in Africa where free hotel accommodations were standard for a layover over 3 hours. A little embarrassing that an airline in America can't afford a hotel for people stranded in a city overnight."

Cons: "We were rushed onto the plane to sit on the tarmac. After waiting to take off for 45 minutes, we were told that our route had been closed and they were looking into other options. This was a flight from NYC to DC, route is closed? Once we finally got into the air, all was good."

Cons: "ATC delay on take off and then a 10 min wait for a gate a DCA. Just disappointing in adding delays."

Pros: "Pulled from get on time. Short hold on runway. Easy landing."
Cons: "Still arriving in Washington where we have no gate. Being on time stinks because you still sit on runway. AT the destination. I would focus on quicker turn around and less accommodation of highly variable flight times in tight NE corridor"

Cons: "We sat on the tarmac after landing for 40+ minutes."

Cons: "They could've fed us or least gave us more drinks when we were rerouted and stick in the Norfolk airport for hours."

Cons: "Plane from BDL was delayed which led do a missed connection in DCA. Rebooked on the 335 pm flight which is 3 hours later than my original arrival time. Very inconvenient for me as I had previous plans."

Pros: "Good view"
Cons: "Breakfast does not have good things to eat. Too cheap ones.."

Cons: "When the pilot took off at LGA he said "everyone here is trying to take off at the same time" so we'd be delayed by 30 min. Not once was there a mention of any other reason. By the time we got to DC I had JUST missed my connecting flight. It was listed nowhere on the departures screen and I realized I had to take an outdoor bus to the other half of the "c" terminal which was very confusing. I got there and had missed the connecting flight and stand in line for 20 min for someone to tell me that I would be stuck in DC overnight. At this point rain had started pouring and they told me that because my mishap was due to weather they would provide no meal or hotel voucher. Weather was not the issue and I was stuck in DC overnight by myself and not compensated for hotels or meals."

Pros: "The crew was good."
Cons: "Washington airport grounded our flight for no apparent reason while we were on the runway in Indy about to take off, then didn't tell us when we could expect the delay to end."

Pros: "Everythingit was good"
Cons: "$75 to pay to change the time of flight, is a lot of money for a person who has roundtrip tickets on the same da"

Cons: "First was delayed resulting in me running from one gate to the other only to find out the 2nd flight is also delayed. Then boarded plane sat on tarmack with no AC for over an hour. Then when we got to final destination had to sit on tarmack again for another 1/2 hour because no gate to unboard. Resulted in almost losing hotel room and having to pay crazy price for in room service. Now suffering due to not enough sleep. AA did not offer ANYTHING for the trouble. Almost treated it as business as usual."

Pros: "Easy boarding, good leg room, clean, on time (actually left 2 min early)"
Cons: "Only gave out water more than halfway through the flight. Flight attendants seemed unhappy to be there and i was afraid to ask them for anything. My bag was force checked even though it would have fit in the overhead."

Pros: "Average flight nothing exceptional or poor."
Cons: "Orlando airport and security checkin was horrific. The most disorganized I've ever experienced. Horrific!!!"

Pros: "Arriving at destination"
Cons: "The airlines have made the aisles and seats so narrow their is no comfort or personal space. Reminds me of the trailers packed with pigs headed to slaughtered. Except we pay. And when fuel prices fell out tickets did not. TSA lines taking two hours due to total incompetency of the Fed government."

Pros: "The flight attendant for our section was very friendly and attentive to everyone."
Cons: "Drink service was delayed and cups were a little light..."

Pros: "Fast, fast flight that even arrived early. Crew gracious and helpful. The fare was cheaper than Amtrak."
Cons: "USB port at my seat didn't work, no inflight entertainment screen because I was on an older plane. But for such a brief flight, that's not much to complain about."

Cons: "Just wish they had electricity to charge gadgets on the flight (even Megabus has that these days!)"

Cons: "Delayed by approximately 1.5 hours"

Pros: "The fact that I got home"
Cons: "AA first delayed the flight, then delayed it again, then cancelled it. While their automatic message said they would reschedule my trip and call me with the new information, having relied on this before only to receive a recorded message two hours later saying they could not reschedule and asking me to call them, I called them right away - only to spend 90 minutes on hold. Then the AA agent tried to book me on two flights that ultimately did not have seats. Finally she booked me on a flight that was 24 hours later--and when I got to the airport, I had to spend another 20 minutes at the counter because, according the counter person, the AA agent did not get the details right. AA cancelled my flight and yet all other airlines kept flying. This is the third time I have flown AA and the third time that they have cancelled my flight and delayed my trip home by 24 hours or more. I've lost three days of vacation due to AA. I will not fly them any more."

Pros: "Great crew!!"
Cons: "There was no food onboard. Entertainment was of the overhead variety."

Cons: "Seats are terrible."

Pros: "Newer equipment"
Cons: "Laughably long line for bathroom, zero legroom"

Cons: "They cancelled our flight three times and would not try to give us a direct flight. We ended up booking a whole new flight with Jet Blue!!!"

Pros: "A newer plane."
Cons: "Flight was delayed for more than 40 mins."

Pros: "Plane took off and landed at the exact time Seats plenty a room ."

Cons: "Plane was late arriving then they took forever to board. Once in board we find out that they can't take off because they need to fix the "entertainment system" but apparently they sent the wrong technician who didn't know how to fix it and had to wait for the right one. I'm not even sure what had to be fixed since there wasn't even any entertainment offered after they fixed it. Once we arrived there were about 100 bags sitting in the bag claim and an equal number of people standing around waiting for bags. None of which was associated with our flight. Then it took forever to get the luggage out for our flight."

Cons: "My first flight was cancelled on Sunday. I was rebooked for Tuesday morning, and then thay flight was cancelled too. I was told there were no more flights to DC until Saturday, which was totally unacceptable for me. I got on standby to a flight to Philadelphia but had to rent a $220 rental car in order to get home at a reasonable time."

Pros: "The flight was pretty standard. No food, of course, and kind of subpar entertainment. But, the crew was fine and boarding was fine."
Cons: "We circled for awhile, not American's fault, but it didn't make for a more pleasant flight especially in the cramped seats that American's planes have."

Pros: "Seat was comfortable and crew were friendly. Flying experience was OK."
Cons: "Status was not recognized - as an EXP traveling in Economy, no snack provided. Agent at Admirals Club in Chicago wasn't aware that transcon flight I had later in the day provided for lounge access."

Pros: "Quick and efficient boarding. Would've liked to picked my seat beforehand"

Cons: "7 hours late departure for the flight to be diverted to another airport. To get home I had to drive two hours from the diverted airport to DCA where I was headed. Along the way the crew was great, but American is run by someone who does not care about customer service. I won't be flying with American anymore."

Pros: "2 hour flight and a 3 hour layover was ok break in-between flights chance to get food."

Pros: "It was actually to Philly, because AA cancelled my original connecting flight out of DC."
Cons: "On the flight back home, AA cancelled my connecting flight, and did not bother to notify me, even though I have my account set up for them to notify me of flight changes. If not for the Kayak app on my phone, I would have flown to an airport where I may well have been stranded for hours, if not the following day, for a flight that no longer existed, since I had already checked-in on-line and would have gone directly to my first flight. Thanks to flight status monitoring by Kayak, I got an email from Kayak telling me that the flight was cancelled before I left for the airport so that I could go to an AA desk. They were particularly unhelpful and uninformed, and it was only sheer luck that I was able to get on the first flight I was on stand-by. I know this sounds like a commercial, but put the Kayak app on your smartphone and don't travel without it. AA will quite happily leave you stranded without it!"

Cons: "Now that American has completed their takeover of US Air, they have downgraded the planes on the CHS/DCA route to crappy little Canadair regional jets. Boarding/disembarking at DCA is via bus at the dreaded cattlecar gate 35X. What was a pleasant flight experience on US Air is now something to dread. Fortunately, Jet Blue also flies this route with full size planes and boarding gates."

Pros: "The flight itself was uneventful, but I was extremely dissatisfied having to reschedule 2 flights on very short notice"
Cons: "I had a 3 leg trip: Seattle to NY to DC to Seattle. First my early morning non-stop flight from Seattle to NY was cancelled around 5 PM the previous day. I was able to get on another flight with one stop and was stuck in middle seats for both flights - although I had paid for a premium seat on the nonstop flight that was cancelled. Then I got notified around noon that my 5:15 PM flight from NY to DC that day was cancelled. American left me a voice mail that they had automatically rebooked me for the following day without checking to see if that worked for me - despite that fact that they had other same day flights available! I was able to rearrange my schedule and get on an earlier flight - but was extremely unhappy with the short notice, and their assumption that I would be fine getting in the next day!"

Pros: "I arrived safely. No ill-behaved passengers."
Cons: "Cannot get seat assignments on line. "Sorry!" says the message. Late take-off from BDL. Gate attendant doesn't like answering questions and could be friendlier. Having to check roller planeside. Would prefer a larger plane. Plane could have been cleaner. Delay at DCA while waiting for jetway. Couldn't robots move the jetways to the planes?"

Cons: "Overall the flight was great. I was carrying a suit in a hanging bag and asked the flight attendant in first class if there was a place I could hang it. She politely offered to hang it behind the last row of first class since none were in use. When getting off the plane, I grabbed my bag as I walked off and the other flight attendant said "you can't put your bag there, it isn't for you" to which I replied that I was told I could use the hanger. She then said "well you shouldn't have been given permission, and don't do it again, it isn't for you." The tone was a bit rude, and maybe the consistency should be reviewed."

Pros: "I didn't fly American to Melbourne. I flew American to LA then flew Qantas to Melbourne. I would never fly and American owned are line to Australia again. They are just not as good at it as Qantas"

Pros: "The flight was on-time."
Cons: "The seat, again, was the bad news."

Pros: "Fine for what I expected"
Cons: "Fine for what I expected"

Pros: "Flights were on time! Flight attendants were really pleasant and both flights were really smooth despite some turbulence at times!"

Pros: "efficient boarding good information from pilot"
Cons: "arrival 45 minutes late"

Pros: "Time management"
Cons: "Service"

Pros: "I have gotten used to the added costs for baggage. At least they didn't charge me for a seat assignment this time. The crew were nice and the flight went well."

Pros: "Everything went smoothly for the most part. Any chance you will get on flight wifi soon?"

Cons: "Lost bags"

Pros: "Getting off the plane was the best part"
Cons: "Babies crying kicking my seat screaming in my ear"

Cons: "seats"

Cons: "Same screaming infants. They were able to sleep but allowed to roam aisles."

Cons: "Plane was dirty, flight delayed, lost my bag, awful."

Pros: "On time, smooth landing, polite flight attendants"
Cons: "Seats, tray tables, pay for carry on"

Pros: "Despite DIA being closed the day before, we were only 35min late for departure, flight was without event and a timely arrival at DC. It may have been cheap, but you got what you paid for..."
Cons: "Bloody small seating, no refreshments."

Pros: "Nothing"
Cons: "the crew was incredibly rude (to others and myself) the flight was delayed three hours and we weren't notified until we were supposed to board"

Pros: "It was fine--took off, polite crew, and landed safely. Can't complain about that."
Cons: "Our plane was delayed for over an hour. Picking up a bag from Frontier takes forever because you have to check what would otherwise be a carry-on. I wasn't aware of this as it was my first time flying with Frontier. Knowing that, I'd be able to schedule better. Don't love that they don't really give any refreshments or snacks."

Cons: "There was a 4 hour delay that a notice went out 2 hours before boarding- which is too late because everybody was already there. And the email still encouraged us to come to the airport just in case. Which meant sitting around an airport 5 hours. Also, there are no trays on the back of your seat. There is a small metal bar that pulls down but it is too narrow for a computer, tablet, book or even to sit a cup of coffee on- which by the way- costs $1.99."

Pros: "Nothing"
Cons: "Everything"

Cons: "There was no mention of a delay while boarding but it took an extra 40 minutes to get started. There were storms in dc and our plane had to be redirected to a different airport. We were not given accurate information or updated with any frequency. We would be told more information is coming in 15 minutes, then sit for an hour and hear nothing. i could not update my driver that was at the original destination airport. While stuck on the plane at the new airport we were told we could not get off the plane or we would not be allowed back on and if we decided to get off and drive we could not get our checked bags. Snacks were not offered for hours and more than one flight attendant said they were out of everything and running out of water. When they finally offered food, full price was still the only option and they had everyone line up in the back of the plane, blocking both lavatories. Half way through the line we were told we could close the doors and prepare to take off and everyone remaining was sent back to their seat. We waited another half hour to actually take off."

Cons: "They nickel and dime you to death. Leg room is horrible if your over 4 feet tall."

Pros: "I just plain like the Frontier method as it has been done for years. The pricing, seating, employees and most everything else just works."
Cons: "I've traveled with Frontier for years and on previous flights to DCA, I thought I should blame the baggage claim delay on the airport. Now I am told it is a Frontier responsibility and I am livid. It gets worse every trip. This time it took an hour to get our bags and it was clearly unnecessary. The first bags came out at about 30 minutes, but after that they dribbled out with no explanation whatsoever. Someone is a real laggard and they need to be fired! This experience was so bad that it takes precedence over our previous beefs. Boarding could be much better from back to front and the new seats are terrible, but like I said, if the baggage could be fixed, I would be willing to concede a few. At this point, I am ready to jump ship to Southwest."

Pros: "Early Arrival"
Cons: "Paying for a seat"

Pros: "Good travel day!"
Cons: "I took the time to fill in my frequent traveler number. I did not receive TSA Precheck boarding passes like I should have."

Pros: "tray tables, great sleep, cool goat, they let me on with 5 minutes to spare. no frills. wow!"
Cons: "not much"

Pros: "The gate crew was upbeat and kept everyone informed. They took a bad situation and made it bearable."
Cons: "Of course, being delayed an hour is not much fun, but other than that, everyone at Frontier did a great job."

Pros: "except for the food and what entertainment it was over all good"
Cons: "could not pay cash"

Cons: "they cancelled the fligh on me - over booked"

Cons: "Having to sit on the plane for four hours in the same position of the seat."

Cons: "They charged me 70 for bags.... Which is insane.... Without warning basically."

Pros: "Flight was on time. Arrived early. Crew pleasant. Hate the add on's but that is Frontier. New seats not comfortable"

Pros: "They chage me $30 for a standard carian( bag)"

Pros: "The crew was extremely friendly and the initial cost of the flight was excellent however the only reason the initial flight cost was cheap is that everything is an add on ... Checked bags cost $35, carry-on bags cost $40! Everything but water costs extra on the plane, and you even have to pay $13 to choose your "normal" seat! I will not fly Frontier again because after I sum the additional costs I can fly a comparable airline with additional services that are free when compared to Frontier."

Cons: "Frontier not only raised their baggage rates, but they failed to load the luggage of at least seven passengers onto a one-way flight."

Pros: "The crew and boarding. Since I paid for a better seat, I was in front of the line."
Cons: "My seat didn't recline even though I paid an extre $50 for a better seat. Seating is very uncomfortable for me if I can't recline my seat slightly. Seats need to be more ergonomically designed for comfort. Also, not music or TV. The old planes use to give you these choices. The new planes suck!!!!!"

Pros: "Crew was nice and had a soft landing. You do get one free personal item wether it be a backpack or suitcase it's just supposed to fit under your seat and i put mine in overhead anyway so im sure it's fine as long as you get on the plane. so not sure what everyone else was rating. if you plan on extra baggage add it online it's much cheaper if you don't get it online add it at your check in kiosk BEFORE you go through security and it will save you 20 bucks."

Pros: "They should offer a tiered check-in scheme for baggage so it should be cheaper for those with small bags that are just checking it in for the convenience of others to not be cramped needlessly with baggage in their leg space."

Pros: "Staff was friendly."
Cons: "Extra 20% cost of my fare just to bring a carry on bag. I already paid $450, this was highway robbery!!! Having to pay $20 to $50 extra just to select a seat. Plane layout now hows even more crowded seats that are thin plastic like you would get on a tour vehicle where you would only sit for 1 hour. Micro-sized fold out trays can't hold an ipad and coffee cup. Plane left 45 minutes late for no reason. No TS-Pre check. I could go on. I will never fly this airline again."

Pros: "It left on time"
Cons: "Pay for snack and drink"

Pros: "Discounted fare"
Cons: "Nickel & dime for everything Called others up in the checkin line, who were late for their flight before us, causing us to be late and miss flight. Do yourself a favor. Pay a little more, and get a better flight."

Pros: "Nothing"
Cons: "The seats are horrible! It ruins the entire flight! Uuugh."

Pros: "The flight left and landed on time"
Cons: "Issues with check in Paid for check in bag twice Can use electronic ticket Confusion of man at front check in counter with multiple trips to security then back because of ticketing problems changes in departure time with no clarification very soon before the flight error in departure time postings"

Pros: "Nothing"
Cons: "The seats are extremely thin, very closely positioned, absolutely everything is for a fee, so if you weren't exhausted from sitting, you were exhausted from getting nickel and dimed. I will stay away from any Frontier flights from now on."

Cons: "Once I payed for the overpriced checked luggage fee and the hidden carry one fee and then had to purchase a seat on every leg of my flight, it cost me $166.00 to print my boarding pass. WHAT!!! Biggest scam I of airline moguls I have ever dealt with. Not only will I never fly Frontier again or never recommend Frontier to anyone, I will surely go out of my way to make sure everyone knows what a rip off it is to fly Frontier. I could have flown on a decent airline non-stop with a soda and maybe even a movie for what it cost me to fly frontier."

Pros: "Nothing, it was the worst flight that I ever take."
Cons: "Customer service was a bummer. Charge for carry on? !!!!!! It's like stealing. It's stupid and it's not fair. The seats was so tide, it was like clastrophobia. All in all, bad experience ever."

Pros: "We arrived at our destination."
Cons: "2+ hours late. No power adapters. No wifi. No entertainment. No food."

Cons: "Stupid extra fees hidden. Just come up with one ticket price. Used to be able to do it easily. WTF? Only thing free is water. Seriously? Learn how to run an airline. Terrible, terrible, terrible."

Pros: "Crew were great."
Cons: "Cost of ticket, costs for any and everything including carry on and cost for a seat assignment, any seat assignment including a middle seat. Seats are hard plastic, no support or reclining options, yet cost extra for assignment. Once all ancillary fees are added up, Frontier is not a value to other competitors. The baggage did not arrive at the claim for 45 minutes after debarkation. I'd say that was unusual, except it took over an hour for bags on my flight home. It's apparent that cost cutting is priority, just not realized in value for flyers. A long fall in service/value from its past under current management. I will not be using this carrier again."

Cons: "$60 for a carry-on; seats don't recline; tray is minuscule."

Pros: "Cheap ticket price."
Cons: "Poor in flight experience, extra charges for basics."

Pros: "I love kayak"
