Pros: "Everything ran according to schedule. Everyone was professional and nice."
Cons: "I wish all families with young children could always pre-board; that was not the case on this flight. The gate agent “let” us board with Group 4, which was at least something. No tv screens on these seats. And I really don’t like the full-volume pitch for the AA credit card. They’re trying to take advantage of a captive audience, and no one likes it."

Pros: "Seats are fine but confining."
Cons: "Need more overhead luggage room, more seat room, missing individual monitors to watch a variety of programs."

Cons: "Breakfast - lots of sugary items"

Cons: "The plan was 20 minutes behind schedule on departure and to top it off they had me pick up my luggage and check in again making me miss my connection. As a result I lost my train ticket fees"

Pros: "The flight was great. Lots of movies to choose from. Food was pretty good too."
Cons: "They moved our flight around multiple times. We first had a layover in Chicago then through multiple emails and one phone call they just flew us straight to London with no layover. It all worked out it was just stressful not knowing exactly when we were flying out and if we were going to make our connecting flights. It did work out and we did make it."

Cons: "It was cancelled. Rebooked via support the whole route on to the next day. Airport AA staff is very unprofessional, they tried to put solving all problems onto customer the customer shoulders. Lost ~$500 due to the cancellation and nobody cares to compensate it. Completely disappointed about customer care."

Pros: "Should have booked AA instead of BA."
Cons: "AA couldn't find BA reservation. poor integration of services"

Pros: "One cabin crew went the extra mile for me...rescued a partial dental plate which I had inadvertently tossed in the trash."

Cons: "Plane didn’t feel very clean. Our tray tables were dirty Seats were not very comfortable. Food could do with a little help"

Pros: "On time"
Cons: "Seat comfort was awful. I paid more for legroom but the actual seat was narrower then others. No one told me that. So legs were fine but my hips were squeezed. Seat cushion was also minimal. The base of my back was aching before take off."

Pros: "Crew was really good"
Cons: "Other than the crew everything is really bad."

Pros: "Not much"
Cons: "SFO employee told me wrong gate as gate number changed. Missed flight. Layover in Chicago delayed 3.5 hours."

Pros: "Normally a kayak super fan"
Cons: "Missed first leg of a return flight to london. Was given no options for rebook and my RETURN flight was also cancelled. Iberdola flight operated by American, ticketed by airfare.com. I've never heard of a product where you have to consume one piece in order to be allowed to consume the other you already bought. Legal basis seems very suspect. Do not fly with airfare.com and be wary of kayak vendors unfortunately."

Pros: "New plane, early departures, nice crew, terrific entertainment system."

Cons: "My flight was delayed. I felt lucky when they gave me a place in a plane leaving 1 hour earlier. But that flight was delayed twice because of mechanical problems: the first time we had to go back to the gate and the second time we stayed on the runway just before take off Not enough room in overhead bins. They asked people to check small suitcase or bag."

Pros: "Everyone was so friendly and helpful, especially Ricardo at the check in desk. Our flight was delayed for 2 hours but the friendly staff made it easier to deal with the delay!"

Cons: "I'm getting to Madrid 24 hrs after I was supposed to"

Pros: "In flight movies were varied, with both new and international films to watch. Flight attendants were nice. Boarding was smooth."
Cons: "Spent a while sitting on the plane waiting to take off because of some kind of delay, but that meant I could spend more time watching the in-flight entertainment."

Cons: "We thought we were going to be flying on British Airways American Airways."

Pros: "I really like the 737..the seats were so comfortable. I miss the old school planes when things were quality. The seat declined further and the headrest was comfortable and not too tall. And I especially loved the service of our flight attendants. Overall this was a very quality flight."

Pros: "Lots on in-flight entertainment."
Cons: "Nothing, I pretty much just slept the whole time."

Cons: "Four and a half hours on board and just a cookie? Really!?"

Pros: "Over 2 hours delayed, plans ruined"

Cons: "I was not a fan that the overhead compartment for my row was not available due to the life raft in there. I understand you have to have one on board, but I think it should be more at the emergency aisles. Also the size of the seats and the space you get is not really worth the price anymore. No matter how big or small someone is, its not comfortable. Airlines need to get back to how the seating was back in the day with great leg room and the seats are a bit wider than what it is now."

Cons: "I got to Moscow, SVO. I didn't receive my bag. This sucks."

Pros: "crew was nice. Plane seemed new with nice seats. Entertainment was nice feature."

Pros: "Nothing except leaving American"
Cons: "Changed to a smaller plane from Chicago to Dublin Paid extra for seats on original and didn't get them Flight late because of catering difficulties"

Cons: "American destroyed my family vacation. They took four days to not get us to Dublin. Stranded us in Chicago and had to use my own money to fly back to California without a vacation. Don't do it."

Cons: "Never made the flight due to flight not getting in to Chicago on time. Still stranded here with my son. Supposed to be sent to Hartford then Dublin later today. Overall a very bad experience with American Airlines. Wouldn't recommend travelling with them again."

Pros: "Everything was on time and luggage arrived at my final destination"
Cons: "Free wifi would be amazing :)"

Pros: "NOTHING"

Pros: "The crew was awesome. It was a very nice flight."

Cons: "My tickets ultimately were booked through Kayak/webjet. I will never book through webjet again. You can't directly speak with an agent. They never sent me my e-tickets. I couldn't download my tickets prior to arriving at the airport. It was super confusing because I couldn't figure out whether I was flying on British Airways or American Airlines. I didn't know what terminal to go to. I finally checked in with American even after they told me to go to British Airways. Next, American said that my booking was messed up such that they couldn't check my bag through. So at Chicago I had to exit the Secure area, pick up my bag from baggage check, check it back in and go back through security. I still didn't have my ticket for the chicago-barcelona leg of the trip. At American, they told be I had to exit the airport again to go to British Airways for the Chicago- Barcelona leg of the trip. Luckily, i asked another agent and she confirmed my flight was though American. It was the most confusing flight experience, I have ever had."

Pros: "Plane was on time. Free check of carry-on."
Cons: "Seats are too cramped and extra cost for better seating sucks."

Cons: "The flight was delayed for 2 hours and after seated in the AA plane for 2 hours, the flight was canceled because without pilot?! Changed to a UA plane but after seated in the UA plane 1 hour, the plane needed to be maintenanced. Had been changed to another UA plane. After three times into three planes, arrived Chicago at 3:30am without the checked baggage."

Pros: "Good service, as efficient as possible"

Pros: "Crew were nice"
Cons: "No food, no pillow, stuffed plane of sickness and pathetic drinks on 5 hr flight which I paid $75 to arrive 2 hrs early... this airline is CHEAP. Good things were friendly, sympathetic crew and good movies."

Pros: "NOTHING"
Cons: "Everything. DELAYS___DELAYS"

Cons: "I was told I had to check my duffle bag at the gate, that there was no room for it. When I dot to my dirty seat I found room for three of my bags in the overhead compartment."

Pros: "Pretty comfortable"

Pros: "AA is stepping there game up when it comes to entertainment. Newer planes have power surges, consistent wifi, and screens in the back of each seat loaded with games and movies."
Cons: "My flight was delayed prolonging my trip. Customer service was terrible. And, when I got to my final destination my checked luggage wasn't there. It took them over 24 hours to locate and return my luggage."

Pros: "The TIMING AND ATMOSPHERE"

Pros: "Upon sitting down, I was able to fall asleep almost instantly. The helpful stewardesses were constantly aware of my needs."
Cons: "Check-in desk seemed confused and unorganized. Two very friendly ladies were helping out but were on different wavelengths."

Cons: "Numerous delays and disappointments. Two delays before boarding. Another long delay after boarding waiting for paperwork to be completed. Long taxi period. Waited over half hour for baggage claim conveyor to start rolling."

Cons: "It was seriously delayed"

Cons: "There was in total a 3-hour delay during the flights in both directions. The seats also were extremely uncomfortable. There was no radio and TV in the plane."

Pros: "Nothing. Will not fly Frontier again."
Cons: "EVERYTHING."

Cons: "The original flight was scheduled for 1:25am at SFO - They then delayed it to 2:30am - Then at 2am they said they don't have a crew member available to fly the plane...so the plane sat on the tarmac and our flight got rescheduled to 9:45am and for that 8 hour flight delay, they gave us a crappy $200 flight voucher that has to be used within the next 90 days. I think public transport is better than this airline."

Cons: "Always delayed departure. Poor plane condition"

Pros: "Did not travel due to weather"
Cons: "Didn't travel due to weather"

Pros: "The referee was delayed by over 4 hours due to avoidable maintenance issues. Not acceptable!"

Pros: "Our San Francisco to Chicago flight only took 3 hour and 20 minutes in the air, which was nice, and the crew was perfectly fine."
Cons: "Someone at Frontier is real proud of themselves for squeezing a few extra bucks out of every square foot of plane space, but after paying extra for bags (checked or carry-on), paying extra for seats, paying extra for snacks/drinks, and ending up on a plane with non-existent leg room and non-reclining, board-hard seats, we'll probably never fly Frontier again."

Pros: "Not only were my fiancé and I hit with $130 in fees for baggage, the night prior we decided to upgrade our seats to row 1 for extra leg room for an additional $90. Little did we know for that price we'd be jeopardizing the ability to reclining our seats...on a red eye flight. I'm incredibly disappointed in frontier. I use to fly them frequently to/from SFO to the Midwest and the quality of service has decreased tremendously! These additional fees you tack on are taking advantage of customers and unethical. My family and I will not be flying with Frontier again."

Pros: "NOTHING"

Cons: "You definitely get what you pay for or maybe i should say you get nothing. My flight out was delayed 4 hours. Then my return flight completely canceled due lack of crew. Do not fly with this airline. It will end up costing double"

Pros: "hospitality"
Cons: "Its an old flying piece"

Cons: "Cheap uncomfortable seats make the lack of legroom even more noticeable. Forget about the headrest or even the ability to recline what little but most airlines offer. And to top off having to pay for my bag, the crew apparently just "forgot" to unload my bag and I had to wait for them to deliver it to me later."

Pros: "Flight was good and landing smooth."
Cons: "No beverages or snacks were offered. The flight was a late night flight and there was no where refreshments or beverages could be purchased, hence I was forced to fast for 6 hours."

Cons: "No tv"

Pros: "The flight arrived 40 minutes early."
Cons: "I paid $40 for a carry on. The plane was not pressurized, I've never had my ears hurt to bad on a plane."

Cons: "Surprise suprise, you have to pay for your carry on. But by the way, it's cheaper to check it than carry it. Are you kidding me? Most unprofessional flight attendants I've seen yet."

Pros: "not much"
Cons: "boarding process was a disaster. no one knew what they were doing. $30 for a carry? seriously? No free snack on the plane. Everything cost $5-$10... never again will i fly Frontier."

Pros: "Checking in, reviewing my boarding passing, and purchasing my "carry on" on the app was SO awesome and convenient!"
Cons: "There was a 4.5 hour delay on my return flight to SFO which sucked, but happens, I get it. We did receive $10 breakfast vouchers which was awesome, but I didn't know what they were at the time, so when I went up to receive mine, I asked what it was the lady was over the top rude. I understand it much have been hectic on her end, but I mean, you're in customer service. Get with it!"

Pros: "Roomy seats, friendly stewards."
Cons: "Late departure with no updates posted. No complimentary soft drinks or coffee. No in flight movie option."

Pros: "nothing"
Cons: "crew was rude and very unprofessional spent 30 minutes taxing before take off (probably wasn't their fault but annoying) landed on time but only deplaned 40 minutes after we landed they have no snacks on board, or rather should i say they sell everything and its all pricey there is very little leg room, very uncomfortable flight"

Cons: "The seats, trays, and windows did not appear to have been cleaned in a while (this is why I rated comfort as mediocre)."

Pros: "Flight attendants were excellent... Good humored, fun, good at helping rowdy people settle down... Happy we got to carry on food in addition to our single personal item. Boarding the plane was much easier with so few people trying to take oversized carry-ons onto the plane."
Cons: "Being nickled and dimed for everything... seat assignments should come with the ticket... Tray table? really? Needs another name... tiny shelf? I'm small... so I fit in my seat. The guy in the seat next to me took up some of my seat, too... And he was normal-sized..."

Cons: "did not like that Frontier charged $$ for seat selection before check in at the airport. There was no option for seat selection at $0. All options cost $$ - or you had to wait till airport check in."

Pros: "Upgraded us!"
Cons: "Told us the Wrong carrosol for our baggage."

Pros: "Fast boarding friendly crew"

Pros: "Boarding was easy."
Cons: "all economy seats are in a fixed position and do not recline. In order to get a seat that reclines you have to upgrade for an additional $50 per seat. Non-reclining seats are OK for short hops but are extremely uncomfortable for long hauls."

Pros: "Nothing"
Cons: "The flight attendants were rude and not helpful"

Cons: "Flight was old and couldn't adjust seat when we get to airport was big line and only one agent working I won't take this company any more dispointed"

Pros: "The staff was very helpful, I needed assistance and they were there to take care of my needs."
Cons: "How the airlines charges for everything except water."

Pros: "Found a very low priced ticket RT to Chicago on Frontier but didn't realize all the extra fees I would potentially incur. The gate waiting area has plenty of charging plug/usb outlets; a nice feature. I would suggest you only fly Frontier on short flights and if you are traveling minimally."
Cons: "Frontier nickel and dimes you for seemingly everything: paper boarding pass, carry-on bag, seat selection, in-flight soda, etc. The seat doesn't recline and is much too short. I had such a difficult time sleeping because my head would lie against the top edge of the seat; I'm 5'10". If you are trying to use your laptop, put it on your lap because the food tray is only big enough to hold a couple cups of water which is what they serve, unless you want to pay for soda."

Pros: "Where prompt with the wheel chair, and very helpful. on time!!"

Pros: "I'm typically on the Thursday flight from SFO to ORD. For the most part the flight has departed on time and arrived into Chicago early or ahead of scheduled arrival. The seats and space is comfortable. The price is also very competitive over all. The planes have generally been clean. I like the early flight time from SFO and option to arrive into ORD at a reasonable hour."
Cons: "Flight crew is generally rude, and unfriendly. You can notice the difference in professionalism between the flight crew on American Air or Virgin than Frontier. The take off/and landing is not the smoothest, and the navigation through turbulence is poor. The customer service agents at the airports have been rude. I was in the airport security line for over an hour. I had asked an Customer Service rep for help that was walking by to avoid missing my flight. The person ignored me and continued walking. The service charge for carry on is not favorable. I dislike arriving early into Chicago and having to wait on the run way for over 15-20 min before we can get to a gate. Defeats the early arrival."

Pros: "Ilike that the price is better and competible with other airline's"
Cons: "The seats are very hard and you cant recline so on a long trip your back and body starts to hurt"

Cons: "Canceled after asking us to stay for eight hours and already got onboard"

Pros: "Friendly Flight Attendants, but a little bit and I luv seating by passenger window to see the view."
Cons: "Delayed sometimes."

Pros: "The people were friendly"
Cons: "Bering charged for carry on and for snaks"

Pros: "I enjoyed that boarding was fairly quick and the tickets were cheap."
Cons: "the seats were cramped, the tray table is so small it can barely fit a drink, and they wanted to charge $30 for a carry on!!!! I find that completely insane, especially since it's only $25 for a checked bag! you even have to pay for water!!! flight was delayed an hour"

Cons: "40 USD carry-on fee or 30 USD check-in baggage fee not included in the ticket. The plane had things left by previous pessengers (napkins, tickets). Everything on board charges. Not a happy experience. I felt like I was being robbed. Hope that no one will ever be cheated by Frontier thereafter."

Pros: "Extra $60 for carry on bag, no tsa pre-check, uncomfortable seats which don't recline, no free beverages, no entertainment system, extra fee for selecting a seat or you're stuck in the middle without room to move or stretch. It's the last time I fly Frontier if another even slightly more expensive option is available."

Pros: "The ticket cost is slightly cheaper than other major airlines, but you have to pay for everything, including carry-on. Include them in your ticket price and you will end up paying more!"
Cons: "They charge you for everything! Uncomfortable seats"

Cons: "$45 to check my carry on. Just give me the bottom line when you charge me instead of saying I am getting a deal than charging me even more once I carry my own bag onto your plane."

Cons: "Great experience but for the exorbitant bag check rates"

Cons: "I spent the entire day in the airport b/c they strung us along 2 hours at time. Then when the plane was finally ready they had to get a new staff for the plane and delayed us another 4 hours. Couldn't they have planned ahead and found a staff before the plane was ready?!? Or if they had just told us upfront the repair was going to take 8-12 hours we could have made use of our day. Losing a whole day of productivity when you own a small business is catastrophic. Frontier really screwed me over."

Pros: "Nothing"
Cons: "Everything"

Pros: "Notification emails about delay and new departure time"
Cons: "- late departure - we spent 45 mins in plane after landing at Chicago airport and it was not fun - not a variety of food to buy options"

Cons: "Apparently the seats are "pre-reclined". What a joke! My gf and I now call this Frontier Airplanes, because this can't be an airline."

Pros: "Nothing."
Cons: "Paying to sit next to my husband, delayed, got in late and had to sit there for another 45 minutes so instead of getting off at 7:30 it was about 10:00. Crew was rude and pushy and the tray tables were half the size of normal airplane tables."

Pros: "Flight was ahead of schedule"
Cons: "Lack of wi-fi"

Pros: "Flight was smooth, left on time and arrived on time"
Cons: "I knew I was flying a budget airline, but was unprepared to pay for a seat and even for carry on luggage. That felt like hidden ticket fees and might have affected my flight selection."
