Scores according to KAYAK customer reviews
Pros: "everyone professional and polite very nice."
Cons: "I cant think of anything"
Pros: "Intertainment"
Cons: "Buying a ticket with connecting flight and having 2 diferent airlines combined can get wrong information to customers. I thought I had bought my ticket thru delta and turns out is was with aeromexico, delta has no weight limit on carry on luggage and aeromexico does, i received an email from delta airlines for me to check in so i look at their luggage policy on carry on and when i arrived at the airport i had to go to aeromexico counter to check in one luggage and turns out i also had to pay for my carry on luggage becouse it exceded aeromexico carry on weight policy which i didn’t fully agree but ended up paying anyways"
Cons: "space"

Cons: "Temperature in cabin whille boarding was ridiculously hot . They didn’t turn the ac on until we took off. Very uncomfortable"
Pros: "Nothing at all, we were left in Mexico with an under 2 years old boy. Reason, apparently we were late but we were not and simply Aeromexico probably oversold tickets and put others in our seats"
Cons: "To resolve our problem. Supervisor was so disrespectful and treated us so badly we had to get ao mad at them so we could get at least a hotel to spend 17 hours until our next flight which they wanted to provide"
Cons: "Pric"
Pros: "I liked that there was no bag fee. A meal was included with each flight. Complimentary cocktail! Free entertainment and all flights were on time!"
Pros: "Great crew and good pilot."
Cons: "No onboard entertainment and no meal selections."
Pros: "Punctual departure. Efficient process."
Cons: "It was fine, really."
Pros: "The service on the plane is ok."
Cons: "On the trip Mex to Bogota, the airplane belated to landed, around four hours after. First it was almost landed to Bogota, we were on El Dorado airport and then back to the air and then going to Medellin airport for landed. So they keeped us inside the airplane (I do not how many time, but maybe 1 an half hour inside) and then back to Bogota for landed. So it was awful and worried time."
Pros: "Quick entrance from JFK"
Cons: "Horrible terminal service will not fly ever again with aueromexico"
Pros: "I enjoyed it"
Cons: "Good overall service"
Pros: "Everything went smoothly except for the sprint to catch the flight out of Guadalajara to Mexico City. That connection was a little tight. The Aeromexico staff were helpful and friendly both on the ground and in the air."
Cons: "The sprint I had to run to catch the flight."
Pros: "Service was good! Didn’t have problem"
Cons: "Flight was on time nothing to say went bad"
Pros: "Good flight, on time, efficient boarding and crew."
Cons: "Our seats were next to emergency exit, didn't recline and the person infront reducer my space when reclined fer seat back."
Pros: "Everything"
Cons: "Everything was great"
Cons: "For a 5+ hour flight, no entertaintment, no movies, headsets did not work, no air conditioning, poor service, bad food."
Pros: "Nothing"
Cons: "Everything"
Pros: "The crew is great, and the comfort of the airplane was outstanding!! Really happy with the whole experience."
Cons: "There was a 5 hour delay which caused me to miss my connection. After standing in line for 3 hours, They did not get me the same day flight and put me on a Latam air flight and asked me to take the bus to terminal 1. When I spoke to the person on Latam air they said they don’t have a ticket for me and sent me back to terminal 2 via a bus where Aeromexico desks were. I stood in another line for 3 hours! Then they told me there is no flight and they will put me on the next day flight. However they did not provide any help or accommodation for the night I had to stay in Mexico which felt very very unsafe to me."
Cons: "Our flight was delayed"
Pros: "Puntuality"
Pros: "The comfort level on Aeromexico's planes to Mexico City and beyond is beyond belief, in this age of shrinking passenger space. In an ordinary ("back of the bus") seat in coach there was more than ample legroom for a more-than-six-footer, and row 28 has two windows to look out at the scenery aft of the wings. And food was even provided at no extra charge! In this situation there certainly was no need to purchase at an additional cost whatever Aeromexico calls its "premium economy" seating."
Cons: "The entertainment system is limited --- there are no games on the seat-back installed machinery. In addition, the earphones provided are only ear-buds, which don't work well in my ears. (I prefer the miniature headphones other airlines provide.) The volume controls were also poorly scaled. The lowest three levels of volume weren't enough to even hear a single sound, the next level up was a little soft or quiet and the highest level far to loud to preserve a listener's hearing."
Cons: "Old plane, late with no notice. Poor seats."
Pros: "Crew is pleasant and professional."
Cons: "Boarding process is incomprehensible and had nothing to do with your location on the plane. Very inefficient, particularly on a large 777. Pilot was very quick and used "beyond our control" as an excuse for every delay. 6 hour delay in Buenos Aires and 1 hour on the tarmac in Guadalajara. Reading light didn't work and TV screen was unwatchable."
Cons: "The customer service was horrible. The worst I've ever experienced."
Cons: "I tried to call TWICE to make sure that I could change dietary preferences because I have food allergies and I was told both times that I was unable to. This is not fair for the price paid for flights. I am very unhappy with the fact that there was food served onboard and that, when I tried to tell the airline what I could and could not eat, that they did not change my preferences or even give me the option."
Pros: "Please see the above note"
Cons: "Please see the above note"
Pros: "They rebooked us on a non-stop united flight"
Cons: "Charging ability, a movie, free bag would be nice"
Pros: "Nothing"
Cons: "I purchased a first class ticket, but the airline changed Equipment to a plane without a first class cabin. I was unceremoniously bumped back to coach and placed in front of two screaming children who proceeded to yell, kick my seat and hit me in the head for the entire flight. Never fly aeromexico"
Pros: "Again, great service."
Cons: "I was not able to connect to the WiFi."
Pros: "Some of the staff (especially at the counter) was nice. The entertainment was good."
Cons: "Flight attendants weren't particularly nice or helpful. No veg options to eat. Had to wait forever at the tarmac."
Pros: "If you have not had the chance to flight in this plan, you have to, it offers more space between seats, and the comfort is in another level. Plenty of choices in entertainment about 20+ movies to choose. Food and service were great."
Cons: "Landing was not the best but considering it was windy, it is acceptable."
Cons: "Flight was delayed but this helped us because our flight prior was also insanely delayed."
Pros: "I like the service on my way back home. The movies were up to date."
Cons: "On my way to mexico wasn't as pleasant because i wasn't served anything to drink. The flight attendant asked me but then walked away and never returned."
Pros: "everything"
Pros: "I appreciate getting a light dinner and the choice of being able to watch a movie."
Cons: "The flight was delayed almost 2 hours from the Medellin airport because of "weather conditions", however in that time I saw two other flights from two different airlines take off on time without a delay. Needless to say this was frustrating. Once aboard the flight, the crew waited until we were landing to hand out the proper migratory and customs forms.That caused a lot of anxiety among travelers who weren't familiar with the forms, causing further delays when we had to stand in line for customs and immigration in Mexico City. Many people lost connections and it was not clear by Aeromexico crew where they needed to go to get their new tickets."
Pros: "Flight staff excellent"
Cons: "Seating sucked"
Pros: "Price and staff"
Cons: "Snack was a tiny bag of peanuts, plane was old and dirty, no in-flight entertainment."
Pros: "Staff was friendly and courteous."
Cons: "I canceled my trip I'm going to use different Airline"
Pros: "Entertainment"
Cons: "Not enough drinks offered"
Pros: "My experience was great. The plane was comfortable and I enjoyed the food and the entertainment provided."
Cons: "Checking in at JFK took a while."
Pros: "The pilot gave all the information pleasantly. It was easy to find my seat and everyone was compliant with COVID-19 rules/restrictions."
Cons: "Boarding process could’ve been a bit quicker. There should be free accessible WiFi for everyone."
Pros: "Crew amazing!!!"
Cons: "Better maybe in giving drinks every once in a while like they use to."
Cons: "Flight attendants need to enforce all policies. It makes no sense to enforce a seat being leaned back a 1/2 inch but allow a Face Mask be worn as a Chin Guard through the entire flight instead wearing it properly!"
Cons: "Great"
Cons: "The seats were tiny! I'm a big woman, but not a huge one and I struggled to get my belt on. Considering how nice their seats are, this is one of the smallest seats I've ever sat in!"
Pros: "The crew was great and provided a quiet environment for the red eye flight."
Cons: "The boarding process needs to be reevaluated. Perhaps the plane should be boarded from the rear to the front or from window to aisle seat. These suggestions would streamline the boarding process."
Pros: "Nothing"
Cons: "Flight was delayed 3 hrs"
Pros: "Great crew and service"
Pros: "Awesome Customer Service"
Cons: "Nothing"
Cons: "More space."
Pros: "Easy flight. Free drinks and snacks. Nice crew."
Cons: "No individual entertainment. Do not help those that are AA members"
Cons: "The crew seemed annoyed and not into it."
Cons: "There was room for my carry on, although they said it was full and cheked it"
Pros: "?"
Cons: "the fact they changed my schedule and had to come in earlier customer service was awful and my luggage came back dirty and the best response was that the belts are dirty and i can expect wear and tear. not only that i had to book myself an earlier trip to pay the standby fee so i can leave the same time my brother left tsa screening had us wait 20 min before we move in the line for the fact no worker was there but one guy and i was the last person to board the plane after almost missing closing gates my expierence was awful and disrespectful"
Cons: "Pushy crowd.."
Cons: "Over 45 mins for bags to get on the belt ? Ridiculous. Won’t fly with AA again"
Pros: "Teeny little plane but easy (early i think!) boarding process and nice flight attendant."
Cons: "We were in quite a long line to take off and when we arrived in bmore there was no one to manage the jet bridge and we sat for a little while. Seems like these issues should be easy to solve - you know when the plane is arriving for over an hour!"
Cons: "Same is last."
Pros: "Amazing and comfortable"
Cons: "We left a little late."
Cons: "super delayed, then delayed more on tarmac due to OVERVfueling."
Cons: "Getting canned and put on a flight five hours later. Good job AA"
Pros: "I was under the weather and she was very very very helpful Mary and all AA flight attendants are great I will fly AA as often as I can because of Mary"
Pros: "-Efficient Boarding -Great flight attendants -Communicative Pilots (flight time, number in line on runway, etc)"
Cons: "Did not dislike anything on this trip."
Pros: "Got two seats to myself."
Cons: "I don't even know who our flight attendants were. Did we have them? Isn't that a requirement?? Guy in seat in front of me was super rude (yes, I know it's not the airline's fault.). Terrible turbulence (again, not AA's fault)."
Pros: "No problems."
Cons: "All was well."
Cons: "I didn't like the fact that I was told to preboard when I checked in before the flight and was told by another employee i was in group 6 and shouldnt be in line. Had to explain why I was preboarding and didn't like having to hold up the line. It was embarrassing."
Pros: "People were nice"
Pros: "I like the ease of boarding and the offer of complimentary check-in if the bags. I assume it was because the flight was fully booked. Overall I was pleased."
Cons: "The entertainment could be better during the flight. I also don’t remember being offered any snacks during the flights either."
Cons: "No carry on bags"
Cons: "It was nice. And boarding was good too."
Pros: "Crew was outstanding"
Cons: "Hurried beverage service since arriving early. R"
Pros: "Video entertainment not working for my whole row."
Pros: "The flight out was really comfortable but the flight back was a little cramped. The crew was great."
Cons: "The return flight"
Pros: "flight crew on my way to BWI were great!!!"
Cons: "american airlines does not care about the privacy of their passengers. even after several calls my information wasn't updated correctly and my flight confirmation was passed along to members who weren't even traveling. there was no in flight entertainment and in order to pick seats together i needed to pay extra (i thought i was flying with american not spirit) apparently the only way i can be helped is writing a letter to customer service which they will review within 10 business days. THANKS american for starting a war in my family and ruining my trip. unfortunate the crew is so awesome but the customer service is mortifying, rude, inconsiderate and completely mechanical. i dont ever intend on flying with them again unless necessary."
Pros: "Fast and early"
Cons: "Tv screens kept freezing"
Cons: "Told me that if I checked my carry on bag at gate, I'd be able to pick bag up from from the gate at the other end. Instead it went to baggage claim with took more than 30 minutes."
Cons: "The departure was delated more than 30 minutes and the arrival disembarking was to slow."
Pros: "This JAL flight was actually operated by american airlines using an american airlines plane. This flight was not great compared to the JAL flight we took to Haneda which was actually a JAL plane which was roomier and had pretty good food."
Cons: "Food was extremely salty, overly sauced. The breakfast options were salmon or omelette and i got salmon. It was spongy and didn't look like salmon. It must have been mashed with something else and reformed into a roll form."
Pros: "the flight attendants were very professional on this flight. the lead attendant was very personable when giving announcements and going through the safety procedures on the public address system. the other two attendants were also very professional in their services as well."
Cons: "flight 1920 was almost an hour late with boarding. I am extremely upset because I paid an extra $75.00 on day of to get home earlier but ended up getting home at the same time that I would have on my original flight because the flight was late and I missed my shuttle because 1920 was late boarding. I should be reimbursed SOMETHING for my inconvenience...especially after paying $75.00 extra for an earlier flight."
Pros: "The plane was new and nice looking"
Cons: "The flight was delayed. The crew was rude . Seats were not assigned until boarding NPILWL3B. Of course they give you the worst seats."
Pros: "THE SEATS WERE COMFORTABLE AND CREW AND VERY ATTENTIVE."
Pros: "the flight was great and comfortable"
Pros: "The flight between WA D.C. And Phoenix went well. Very nice staff, orderly onboarding"
Cons: "Arrived in Phoenix and hurried to my next gate for the flight to Palm Springs only to discover a delay in the flight. No marguees were updated, no explanation just the plane had not arrived. Soon after we were told of a gate change, the marquee then said the flight would not arrive until 11 pm it is a one hour flight, so we actually arrived at 10 pm."
Pros: "Short flight. The crew was nice. The food and entertainment should be Not applicable because it's a short flight - I was not expecting it."
Cons: "Boarding was late, very small carry on compartment - maybe because it's a smaller carrier. A lot of people had there carry on placed in a valet service so it took a while for them to get out because they were waiting for their carry ons."
Pros: "I liked how smooth flight went especially after all the bumpy rides I had been on"
Cons: "I didn't like that I wasn't able to sit with the person I purchased my ticket with"

Pros: "Ease of travel"

Cons: "No ice in my water."
Pros: "The time"
Cons: "Everything"
Pros: "Nothing"
Cons: "Nothing. It’s garbage."
Pros: "Fine for what I expected"
Cons: "Fine for what I expected"
Cons: "Tiny trays, additional costs, including a carry-on despite doing a search w/one"
Cons: "I was charged an extra $45 dollars from Denver to DC for my hand luggage. I had previously checked in another luggage from Vegas at the same cost. This meant i had to pay a total of $90 plus the travel cost, which was very unfortunate and very costly. Such communication of anticipated cost on hand luggage was not shared prior to the trip. This was very disappointing and clearly made my entire trip very frustrating. I would not consider using the services ever again."
Pros: "efficient boarding good information from pilot"
Cons: "arrival 45 minutes late"
Pros: "Never, never again!"
Pros: "Nothing"
Cons: "Everything"
Pros: "Same,as above"
Cons: "Same as above"
Pros: "Same as above"
Cons: "Same as above"

Pros: "New, very nice, very clean, very safe plane. I would fly this airline again."
Pros: "Nothing"
Pros: "Comfortable"
Cons: "Frontier is a truly terrible organization."

Cons: "Lost bags"
Pros: "Getting off the plane was the best part"
Cons: "Babies crying kicking my seat screaming in my ear"
Pros: "Size of plane"
Cons: "Staff members not offering water (at least). Only items that cost"
Cons: "It hasn't left yet and you do not know that."
Pros: "Nothing."
Cons: "The check-in agent screwed up our boarding passes and neglected to include our pre-check designation. TERRIBLE luggage and seat selection options. The price indicated is likely at least $100 less than you will end up paying. Rude staff and terrible organization at the check-in and boarding areas too, likely because so many customers are furious at the lack of transparency regarding seating and luggage."
Cons: "Same screaming infants. They were able to sleep but allowed to roam aisles."
Pros: "cheap ticket"
Cons: "- Trays were about 10 inches wide and 5 inches deep - which provides no value whatsoever. You can't place anything on it b/c it's not big enough. - Chairs were short so I had nothing to rest my head on. - Cramped isle space"
Pros: "They gave us a $10 voucher to use in IAD while we waited...for 6.5 hours."
Cons: "The delay seemed like it could have been prevented with a better computer system; we paid for our bags ahead and others didn't have to pay when we checked in because the system was down, no offer for a refund on that."
Cons: "Once you add all of the additional expenses, Frontier is just as expensive as other airlines, but with less comfort and amenities. I've flown with them twice and they have been tremendously frustrating on both occasions. Never again."
Cons: "Lost luggage and delayed takeoff"
Cons: "Communication at the gate was poor. As well as the communication on board the plane."
Cons: "Let people know about their carry on luggage charges!"
Pros: "Everyone was nice once we were on board"
Cons: "Our well-working plane was clearly given to another group, and all we were told was that we had a gate change that then turned into a 2h delay for mechanical problems. If you're giving the broken plane to us because the other passengers have a connection and we don't, say that, don't just act like nothing changed. Also, it's been a while since I rode Frontier and I really disliked the dinky trays and poorly arranged under-seat storage."
Cons: "Baggage for 2 pieces of luggage $75.00 then a gimmicky Visa card to earn miles not cost effective"
Pros: "NONSTOP"
Cons: "ADD-ON FEES MADE PRICE UNECONOMICAL BY COMPARISON. COULD'T USE MY TSA PER-CHECK AUTHORIZATION."
Cons: "more than 2 hrs late"
Pros: "Not much"
Cons: "Horrible space No comp beverage No wifi No magazine Delayed"
Pros: "Warning. Don't book through this site. If you want to be sure that your ticket is valid, go to the airline directly. Only use Kayak as a reference."
Cons: "Fraud alert on my ticket despite money having left my account and my bank having no knowledge of the issue. It all stems from an excess of fraudulent use through Kayak rendering the site all but useless. Sorry Kayak!"
Pros: "made it to DC"
Cons: "delayed 1.5 hours. little information. no apology. no explanation."
Pros: "Nothing"
Cons: "Everything"
Cons: "Seat was awful even though I paid for an aisle."
Pros: "not much You pay for everthing incuding water, its like being nickled and dimed at every turn."
Cons: "3hour delay."
Pros: "It felt very simple and non complex, unlike other airlines where they make the process of traveling a long and tumultuous process. Bravo Frontier!"
Cons: "There was a Lady checking in people at the gate who had questioned many customers of whether their carry-on would fit, it seemed to bother many guests because they didn't want to be charged extra."
Cons: "Paying extra for EVERYTHING. Will never travel with Frontier again."
Cons: "Only food for purchase - did not buy any. No entertainment available, incl music. Seating crowded."
Pros: "Nothing"
Cons: "Everything"

Cons: "could not pay cash"
Cons: "they cancelled the fligh on me - over booked"
