Pros: "The check-in agent was very nice and patient"
Cons: "Our flight kept on getting delays, we were seated separated, a kid was hitting my seat during the whole flight even after skiing the mother to stop her child, not sure what is the solution there but I would suggest that in your announcements in the beginning you could mention a rule of respect to others like in the movies a little subtle regulation about other passengers space respect."

Pros: "Everything was fine—no worse, but no better. Delta crew could definitely learn a thing or two from Southwest. I haven’t been on a flight with Delta where the crew seemed happy."

Pros: "The crew was really nice."
Cons: "The boarding was really crowded and didnt seem organized."

Pros: "Close to on time"

Pros: "Friendly staff. :)"
Cons: "Longer flight with no WiFi or video. :("

Cons: "Nothing to add"

Pros: "Service"
Cons: "Lack of food options"

Pros: "NOTHING"
Cons: "Delayed 15 hours because of a mechanical issue, spent the night in Cancun. Customer service and communication throughout was terrible."

Pros: "Loved the in-flight entwrtainment, choice of snacks, movable headrests and plug to charge electronics."

Pros: "We flew Delta. My husband fractured his ankle and got a cast the day before our flight to Cancun. No turning back Our seat assignments had us separated on some segments and also at window and middle seats. On all flights we were bumped up to comfort seats with an empty seat next to us for his cast and the final flight home put in an earlier flight home to avoid a six hour layover! Delta really went over and beyond expected."
Cons: "Kayak sent me an alert to our flight telling us we left from Terminal S in Atlanta. After several joyvrides on the tram we found out there is no Terminal S!"

Pros: "The plane, the seating, and the service was outstanding, great entertainment setup with the movies."

Pros: "First class service and seats"
Cons: "Lost my bag... very frustrated. Nobody at the baggage claim would give us an answer, they said there might be more bags coming... Then they ran away. We finally wind up at the last bag office and they began the process... We still are waiting for our bag, 14 hours after reporting it missing."

Pros: "I loved that I was able to get home! The crew was nice."
Cons: "It was very very warm in the plane. The entertainment unit was lacking."

Pros: "Staff was friendly. Flight was smooth."
Cons: "Media kept freezing. They had to reboot the system several times."

Pros: "Once we hit the coast we skirted down the coas of Florida which provided a spectacular view. The approach and landing at Key West airport was thrilling and absolutely perfect. We’ve flown Delta many times but this was our first but not last time to Key West."
Cons: "Nothing"

Pros: "The flights were on time and they did two drink and snack services. Great crew!"

Pros: "On time arrival"
Cons: "Nothing"

Pros: "I purchased round trip tickets to Cancun Mexico for under $400. And I received 1st class upgrades both ways. I could not be happier with my travel."
Cons: "No complaints"

Pros: "The A330 is So much better than the A320, More room, movies, games, wish the flight down was on a A330."
Cons: "Nothing- plane was full and pretty quiet. Bathrooms were easily accessed"

Cons: "It was it little confusing that I booked with AeroMexico but it was really a Delta flight."

Pros: "Delta seats are comfortable and media ststem is good."
Cons: "Flight was late and the staff wasn't kind Neither at JFK gate neither on both flights. Looks like they are doing you a favor to listen to you when you ask them something."

Pros: "The weather was bad in Atlanta. We were rerouted to Minneapolis and made a connection to Philadelphia. No problems."

Pros: "The crew on board were helpful"
Cons: "Delta staff at airport were unprofessional. They had us spend over an hour traveling to a different TSA line because they closed the line we were in. The other line was a 10 minute drive away. Also our bags did not reach philadelphia when we landed at 3 am."

Pros: "Flight was fine."
Cons: "My one complaint is the bathroom layout of the A320. Two tiny closet bathrooms in the back for all of coach and a much larger one much larger one first class (which is like 5 rows with a mesh curtain for separation). The coach bathrooms are so small a normal person can barely get in and turn around to close the door. I question whether a larger person would be able to actually use them. I also saw the flight attendant actively turn away coach passengers trying to use the first class bathroom when it was open (not standing in the aisle or anything annoying like that). That's ridiculous to have 2 tiny bathrooms for all of coach and also to make people walk all the way to the back of the plane when you are seated much closer to the first class bathroom."

Pros: "The outbound crew was terrific. The flight itself was fine. We even arrived early."
Cons: "Upon deplaning in Cancun, ALL passengers are put on a bus and driven far away from the terminals to an arrivals area. Those of us with connecting flights are royally f*cked at that point, especially if your connection is short, as mine was. The so-called shuttle to the departure terminals, which are entire kilometers away, was to arrive in like half an hour. HALF AN HOUR. Who has this time to spare?? The alternative to the shuttle is paying a taxi that charges a hefty fare--and God help you if you don't have cash. The departures terminal was swamped and only thru begging assistance and line cuts did I make my connection...and then only by the skin of my teeth. It was a complete nightmare."

Pros: "Movies"

Cons: "The Cancun airport provides a terrible experience for transferring between flights, especially if you need to change from the international terminal to a domestic terminal or vice-versa. There is no way to get between terminals inside security and the free shuttle is slow and overcrowded. Meanwhile, one is forced to run a gauntlet of taxi and shuttle drivers trying to get you to pay them exorbitant fees to drive you to your terminal. Once you finally arrive you discover that there is no dedicated baggage recheck for an international arrival. Just don't buy a ticket that transfers in CUN."

Pros: "Not a good experience. Crew was unhappy, disengaged, seemed too busy and buried."
Cons: "NEverything seemed hurried and frenzied. Airplane was dirty when we boarded."

Pros: "What can I say...I love Delta!"

Pros: "Everything was delightful on Delta’s side. Very comfortable. Great service."
Cons: "Why do parents with infants choose to sit in First Class. Crying babies are not appreciated when I’ve paid a lot of money for a First Class experience. The parents in the sears behind me had a child who cried & cried. It was a real spoiler for me. I enjoyed eveeeythinf about the First Class experience except that."

Pros: "Nothing"
Cons: "The poor service provided to customers when a flight gets delayed, there was no explanation, no gate, we were walking around the airport without any information and the food voucher barely cover a meal."

Cons: "Terrible boarding process. I booked the tickets months ago, but didn't have seats until the last minute. They didn't even put my wife and I together, but sandwiched 2 people between us. Boneheads."

Pros: "Crew was friendly and helpful. Flight smooth and quick."
Cons: "Gate change and departure time change not reflected properly on boarding pass. Problems with gogo in Flight."

Pros: "Delta’s crew were professional"
Cons: "Uncomfortable seats, reclining only about an inch is not enough for a 5+ hr trip"

Cons: "the older stuardess on my flight from Cancun to Atlanta was very misinformed- told me my carry on wouldn't fit in the over head bin... it did. Told me I had to check my duty free liquor.. I didn't. Told me I couldn't bring all of my liquor in to the US... I could. I just kept saying ok to her just to shut her up, but she ensued with her comments and wrong info as if I don't travel as often as I do. Perhaps she was attempting to be helpful, but it came off as obnoxious and rude especially since she was wrong on every accord. Humbleness and customer service training would do her very good. All other DELTA staff have been great."

Cons: "For a competitive price charged by almost any other airline for the same distance, there was no lunch on a midday international flight? That is terrible. To make things worse, the entertainment screen was broken. It did not respond to touches. More of an ordeal than entertainment. To top it all, the current flight info (e.g. time at departure & destination, flight duration) was all wrong. Not a pleasant experience."

Pros: "I Love flying on Delta especially since I'm often upgraded to Comfort or first class."

Pros: "Loved the customer service & movie options"
Cons: "The flight only had snacks for free; wish sandwiches would be given for lunch"

Cons: "The fact that booking with kayak wouldn't let me pick my seats and traveling with 2 kids under 4 it made it very stressful trying to figure out how we could sit together or even the same end of the plane."

Pros: "Nice plane."
Cons: "No in flight TV."

Cons: "My email read check into Aeromexico I could not check in the Aeromexico using my phone I was dropped off at the Aeromexico terminal after standing in line for half an hour I find I was in the wrong terminal I needed to be in a different terminal with Delta because Aeromexico even on my reservation read that does not fly to Tampa. I had to find a shuttle to another terminal the shuttlesare not marked it was very confusing"

Pros: "Staff hospitality"
Cons: "Deboarding delay, seems typical"

Pros: "Flight"
Cons: "Boarding"

Pros: "Crew was great and tried to accommodate the best they could"
Cons: "It was really cold on both flights, they had blankets for only first class and business class. We had an open seat as well next to us and they put a person in the open seat that was drunk and 22. Not cool"

Cons: "We were early arriving on both legs of our flight, which was nice. Charlotte Airport staff was rude as usual, so nothing new there. Overall, we had a great trip."

Pros: "Flight attendants were great. Friendky,.; Had the holiday spirit!"

Cons: "We left an hour late ."

Cons: "Fly faster"

Pros: "I liked that I got to philly"
Cons: "The seats were cramped, plane was freezing cold and everyone was wearing jackets and blankets because the flight attendants wouldn't raise the temp. The pretzel bag had literally 5 mini pretzels and that was it. It was a bad flight."

Pros: "Sears are still too narrow."
Cons: "I wish I could of finished my movie !!!"

Pros: "The crew was slow. Granted, the plane was full and the crew had many passengers but service was slow and cursory."
Cons: "Flying economy on American Airlines is very unpleasant. The seats are too small-the aisles too narrow and the bathrooms incredibly tiny. Only 2 bathrooms in economy for a tremendous amount of passengers. I had requested a bulkhead seat because of hip surgery. I had to purchase it."

Pros: "The crew and plane was great"
Cons: "The first flight was delayed causing me to miss my second flight and having to spend an extra night at my layover location but the airline accommodated me accordingly with a room and flight the next morning Dallas airport was a shambles not being helpful at all with the people who were delayed"

Pros: "I liked the big 787 plane and the in flight entertainment with individual TVs!"
Cons: "Not a huge fan of the captive audience announcements for the credit card and the meal pre-orders"

Pros: "good"

Pros: "On time, clean airplane"
Cons: "Boarding system very odd"

Pros: "That I had no issues. Timely, staff accommodating, area cleaned."
Cons: "Had no concerns..."

Pros: "Nothing"
Cons: "There was no food or entertainment so the rating there doesn't mean anything. Flight was delayed 1 hour due to a mechanical issue. Part of the delay included AA trying to get the flight crew to show up at the gate. The flight was oversold so there was a long list of standbys which added to the crowd waiting at the gate."

Pros: "The crew members had a good attitude, pilot in particular"
Cons: "Two cancelled flights, a dozen delays, and 14 hours of travel later I finally had to rent a car and drive home."

Pros: "The crew was very nice and helpful."

Cons: "Subpar in every aspect. Landing was horrible with a hard touch that made everyone bounce."

Pros: "It was fine. Nothing extraordinary, just solid and fine"
Cons: "Nothing bad in particular. The passengers could've been more friendly, but that's not the airline's fault"

Cons: "Flight delay on both ends of the segment"

Pros: "Nice staff. Seats are comfy."
Cons: "A lot of pushy people. I think it always happens on the flights back from vacation destinations, people are burnt out and want to get home. The American airlines staff were fine, though."

Pros: "Fast boarding"

Pros: "Probably one of the fastest and most Eddie to first class service we’ve had. Shakira was very pleasant and swift."

Pros: "Airport staff were so helpful, they helped my mom out that needed a wheelchair, the American Airlines staff were also so helpful changing seats"
Cons: "The food on the plane was not very good. Also having to pay for checking are bag was annoying. We thought using our American Airlines card would pay for the baggage but they said it wasn't covered ...."

Cons: "My husband is 6'5" and sitting next to him the whole flight was barely bearable."

Cons: "We bought the tickets with 1 luggage included. In the check in, the y charged us!"

Pros: "I think they should learn from other asian airlines, about Special veg meal.also more one cleans levatory."
Cons: "Nothing Other than dservice provided by Korean crew members"

Cons: "Without any explanation...American Airlines cancelled my reservation! I needed to be sent back to poor quality hotel for a night and take a different flight out the next morning. American Airlines was supposed to provide transportation back and forth from the hotel however a car never showed up at the hotel to pick us up and I needed to get my own taxi at the last minute (American did however reimburse me for the taxi fare at the airport). I never received an explanation as to why my reservation was cancelled and was never offered any type of compensation for such a major inconvenience. They dd ultimately waive my 25 bag fee but it wasn't very easy to even get that from them. I felt that they should have been more empathetic towards my inconvenience and offered me any type of compensation to make up for such a horrible experience. When I asked about possibly being upgraded to first class they told me absolutely not! A little graciousness can go a long way, American Airlines showed that they could not care less about my inconvenience (other than Rodrigo at the counter the next morning who actually showed he was truly sorry for the situation and at least ended up moving me to a row with more legroom). Other than this, I was extremely disappointed with this experience and how it was handled."

Pros: "Nothing, I missed my flight bc of lack of paperwork and information from the crew"

Cons: "My direct flight was cancelled. My rescheduleday flight was delayed and I missed my connection and had to spend the night in the airport. My 2 1/2 hour flight turned into a 16 hour trip."

Pros: "Left on time, seemed to have a little more leg room than on previous flights. Experienced some air turbulence, but not sure pilot could have done anything about it. Delayed refreshments, but the attendants still managed to serve everyone."
Cons: "Seemed to take a long time for luggage to arrive; not sure what problem was. Not sure why we had to claim our luggage, only to turn it in again right away."

Pros: "It was a flight, it got me from point A to point B, but everything in between could've been much better."
Cons: "When first boarding the plane, the person I was with tried to close the shade on the window, the with frame and the first 2 pieces of glass popped out. We notified the flight attendant and his response was "can you stick your arm out the window and wave? No... ok you're fine" then we were notified the bathrooms in the middle of the plane were out of order and we could only use the bathrooms at the rear of the plane. There was no WiFi, and the audio system for the on board movies wasn't working. The flight attendants were only giving out cups of beverages and not the full can, which isnt a big deal but still looks bad on the airline considering everywhere flight with American has handed out full cans of soda. The perception was American dropped the ball on the his plane, and just didn't care to do the necessary maintenance. For the his head priced paid for the his hehe see tickets I would've expected better from a reputable airline. Needless to say we were a little disappointed."

Pros: "Check-in went fairly smoothly."
Cons: "Crew (stewardess' were quite crabby)."

Pros: "The leg room in first class."
Cons: "Meal was not good."

Cons: "Ticketing agent was rude"

Cons: "Do not bring blankets!! And the staff not nice"

Pros: "Flight was early both ways. Pleasant experience"
Cons: "N/a"

Pros: "Call me immediately"
Cons: "Call me immediately"

Pros: "There is little to like about air travel on a packed 737"
Cons: "No immigration forms available"

Pros: "The seats, the flight condition, the customer service, boarding experience"

Cons: "I really didn't like the way the company managed the entertainment deal. A 4 hour flite sould have free entertainment. The crew was tired. In the past i liked using united, but now I hope not using this company again."

Pros: "That we landed safely!"
Cons: "Temp was cold, they had no blankets to use, ran out of hot meals by the time they got to our seat"

Cons: "The crew was rude and often in helpful. This is a continuing trend on United and I will not fly united again"

Pros: "Was on time"
Cons: "Flight crew had poor aattitudes at best"

Pros: "On time"

Cons: "my language arrived in 24 hours delay"

Pros: "No delays, everything went smooth"

Pros: "Nothing"
Cons: "I got the wrong seats. I paid for economy plus and requested an aisle and middle seat and ended up with a middle seat and window seat. Horrible customer service from United in Mexico. They did absolutely nothing to accommodate their mistake. United Airlines is awful."

Pros: "Nothing"
Cons: "Had valid tickets bought months ago, but no assigned seats. Only way to make sure I had seats was to upgrade....bush league. Be loyal to the people that plan ahead and purchase tickets on your airline and actually assign seats there and then."

Cons: "When experiencing turbulence, the flight attendant came over the speaker and requested everyone to be seated with their seat belts fastened. A few moments later she came back on reprimanding that "THIS IS NOT A JOKE YOU NEED TO SIT DOWN WITH YOUR SEAT BELTS FASTENED" which was still ok. The third announcement was the one I felt was highly inappropriate when she then stated "I DONT KNOW IF YOUVE BEEN WATCHING THE NEWS LATELY, BUT THERE IS NO WARNING WHEN THE TURBULANCE IS GOING TO GET WORSE" frankly I have been watching the news lately and there is plane CRASHES on the news. My husband is afraid of flying and that announcement was terrifying, even for someone who is not afraid to fly. There has to be some sort of protocol of verbage to use when the turbulance is getting bad, because to insinuate the plane could crash to get your point across is crossing the line. I have been on planes where the turbulance is a lot worse and felt this was really out of line."

Pros: "On-time departure from Cancun but early arrival in Denver (relatively mild jet stream?). Otherwise, fairly typical United cattle carrier."

Pros: "Had to wait 2 hours on the plane because a port was not available."

Pros: "Not much"
Cons: "Absolutely NO leg space."

Pros: "Getting off the plane in Chicago."
Cons: "Plane got pretty warm and didn't cool down much during the flight. In-flight entertainment was poor; DirecTV was the only option and I believe there were some issues due to not being over US soil upon departure."

Pros: "Free movie due to wifi being unavailable"
Cons: "The crew seemed less than cheerful"

Pros: "Flight attendant, Annelle, was very attentive and friendly throughout the flight. The other flight attendants were as well"

Cons: "Delayed flight. Horrible flight:///"

Pros: "Nice airplane"

Pros: "On time flight"
Cons: "stewardess"

Pros: "The crew and drink selection"
Cons: "Delayed, and sat on runway for 45 minutes after landing."

Pros: "The fly was good and the captain as well."
Cons: "The boarding process was a mess and I got the worst seat."

Pros: "The crew was very attentive and caring"
Cons: "MY SEAT WAS CHANGED WITHOUT EVEN ASKING ME The flight was 3 hrs delayed There was crying babies on board so I couldn't even get some rest"

Cons: "on the way there we had TV. On the way back we had to take a different route (which added more time for the trip)and we did have a TV on the head rest or even movie showing. Also one snack that has three crackers isn't worth handing out. It would be nice to be able to enjoy the snack."

Pros: "I liked the timeliness of the flight. we arrived faster than expected."
Cons: "there was an open seat next to my boyfriend and i, we thought we would have a little extra space on the flight since the seat wasn't taken. but the flight attended moves a passenger next to us without notifying us prior or even asking if it's okay, or ask that we scoot down so that we can at least have the window seat. would've been nice to have the window to lean on.. we felt like she could have said something to us. she was very rude."

Pros: "United planes are up to date and clean. Service excellent. All personnel very nice."

Pros: "Great service!!"

Pros: "I liked the sincerely friendly staff; they made it a pleasant experience."
Cons: "I would ha've liked free TV; ,I feel I've paid for it in cost of ticket."

Cons: "I waiting from 9:00 morning until tomorrow 8:00. 24 hours for cancelled this's so crazy and long time and I still waiting for another flight"

Pros: "It was a direct flight."
Cons: "no food unless you bought it no wifi or entertainment at all unless you bought it, or had the united app on your device (which, you can't download on plane). overhead compartments smaller than usual, as was under seat area"

Cons: "We had a two and half hour wait for the plane and no one could tell me anything"

Cons: "They should offer free movies and this silly bags of nuts; can someone be more creative?"

Pros: "The evening before our return to US from our vacation in Mexico, my husband lost his passport. The Cancun airport crew, including Paz and Raphael, worked with US consulate (on a day they are typically closed) to get permission for him to board the return flight. Otherwise, we would have had to stay two more days ( until monday) to go to the consulate. THANK YOU, United!"

Cons: "Waited for 3 hours for the flight to finally be cancelled, then waited another hour for a van to arrive. It's only a 2-1/2 hr drive to begin with! This is the 2nd time of 4 I've booked this flight that it's been cancelled. Doubt I'll ever book again."

Pros: "Great free movies in first class."
Cons: "The first class crew was not very warm or welcoming. The outgoing flight from IAD set the bar high -- they could've spent less time gossiping and more time remembering my drink order."

Pros: "I liked that they made it to my destination on time."
Cons: "Everything costs money on top of the tickets I purchased. To compete with other airlines they are going to have to start including food, baggage, and entertainment for free especially on international flights."

Pros: "Free entertainment because of the bother"
Cons: "Having our flight delayed. The pilots were still in Houston when we boarded the plane in Cancun. Sat on the plane 2.5 hours before they cancelled due to staff being over the limit of hours they could work. Surely this could have been realized before they boarded us! Very sloppy management of us on the plane, getting off the plane with staff saying "we don't know what's going on""

Pros: "The pilot flew the plane well and kept us informed about the route."
Cons: "Our luggage was rummaged through and jewelry was missing from inside the checked luggage!!!!!! Not to mention the fees for traveling with a regular piece of luggage that was well within the weight limits. SOME of the crew was rude (the guy was polite). They sell everything meals, entertainment, etc on board it is already pricey to fly and I guess it includes nothing but your right to sit and breathe. . The plane was cramped and there was trash by my seat probably from a previous flight. Also, I did not get to sit by my travel companion."

Cons: "It was a bit delayed"

Pros: "I had a complaint of overly noisy passengers in front of me as did others. Finally when spoken to about it by a femal stewardess they sat sticky quoted down."
Cons: "When I boarded and got to my seat o found it dirty. The steward had me ubvelcro the cushion so he could wash it off but their was a lot of food debrie from previous passengers. I didn't feel like I was sitting in a cleaned space for the duration of the flight"

Pros: "It is apparent that United is working to improve their customer service and efficiency - factors which have deterred me from using United in the past. FROM SFO TO CANCUN: First of all, the check-in procedure is very quick these days. At SFO, there is a curb-side check in, which also allows customers to pay the baggage fee and drop off the bag right there. I've used this in the past during busy airport hours. This time, I flew overnight, so I used the self-check kiosks in front of the check-in counters to check-in, pay the baggage fee, and print my ticket. I used the check-in line to check in my suitcase. The line was so minimal and moved so quickly, (as did security), I was at the gate in 30 min (from the SFO BART station). I rarely fly United because the check-in lines used to be very long and slow. In the past, I've missed more than one flight due to extraordinarily long check-in lines. I'm glad to see on the last 3 flights I've taken with United, this has changed for the better. FROM CANCUN TO SFO: I was happy to see that Cancún also has kiosks for self-check-in. It wouldn't allow me to check my bag, though, and I had to wait in a slow line to do so. Still, a much improved check-in compared to past experiences. *I should note: the slow line had 8 people in it and took 25 minutes. With many people, United Cancun lines have been known to take over 2 hrs. This was a Thursday afternoon on January 8. I'm not sure what the line would have looked like the Saturday before . . . BOTH FLIGHTS: The stewardesses did come by several times (as opposed to once on other airlines), offering water, which was appreciated. Finally, United tends to offer multiple flights at cheaper prices and more convenient times than other airlines. However, I still prefer flying other airlines - despite the increased cost - for the reasons below."
Cons: "United planes are older, outdated, and very small. The video system on the back of the headrest in front of me did not work on either flight (there or back), and no snack of any kind was offered on the afternoon 4.5 hr flight back from Cancun to SFO. A mini bag of salted peanuts were offered on the overnight flight from SFO to Cancun. But these were the least of my concerns. Deplaning was slow and long when we arrived at Cancun. We waited with the plane door closed, and the air off, for about 10 minutes. It was a hot, humid, uncomfortable wait. Deplaning took a long time due to the small, cramped seats (see description below). On the return flight to SFO, we waited on the runway in line with other planes. While this is not the fault of United, it did make passengers more anxious to deplane. Opening the plane doors took a long time, and exiting the plane even longer because people were slow getting out of their seats and recovering their bags from the storage bins. I saw people struggling to crab-walk out to the isle on "dead legs" (the floor space between seats is so minimal, no one can stand up straight, and must grab the seat in front of him/her to shuffle out to the isle - a difficult task for the elderly, or when carrying purses as big as carry-ons, sleeping toddlers, or babies). The seats were extraordinarily hard and small on both flights. I fit in the seat just fine, but had no leg space, and could not recline. In effect, I was forced to fly the entire time in an upright position, sitting on a rock-hard seat that felt like thin plastic-leather stretched over metal bars. I'm a young 40yr old traveler of normal size (5'4") and health (135 lbs), yet it was extremely uncomfortable sitting on that seat with no way to redistribute weight. I had pain in my legs for over 24 hrs after flying United from Cancun to SFO. I flew 6 round trips to Miami and Mexico City last year from SFO and never had this happen. I've flown to Peru and Miami direct - and much more comfortably - on other airlines. I will not choose a direct flight over 2 hrs on United again, and will continue to choose other airlines whenever possible."

Cons: "Unorganized boarding process, had to pay to check my only bag I brought, no complimentary snack, no options of movies or channels to watch. For such a long fligjt some kind of options is appreciated"

Pros: "Great customer service and spacious seats"
Cons: "The check in fees & maybe the staff could seem a little bit more excited when we Landed in Cancun."

Pros: "The flight was smooth and no incidents. The plane was clean and the flight attendants courtesy at the higher level."
Cons: "Even if I had the app downloaded I couldn't watch anything...kind a boring. Hope that they can fix that for the future."

Pros: "Leaving Cancun I was instructed to consolidate my purse into my overhead bag. In this process my cell phone was left at the terminal gates. At Houston lost baggage counter a wonderful woman was able to connect with the airport security in Mexico. Locate my phone, arrange for a hold and friend to pick it up in two days when she was flying out of the same terminal. I greatly appreciated everyone's effort to go the extra mile and the Mexican staff was beyond helpful especially since I was coordinating this all from the US with broken Spanish"
Cons: "Leaving SFO to Cancun, a horrible experience two day delay due to weather. No offer for even a toothbrush was given, no refund for any part of the tickets or costs of delays. I managed to leave the airport and return, waiting for several flights I was finally able to fly standby with a layover into Mexico DF and on to Cancun. Arriving three days later than my original plan. The most frustrating part was on the second morning people were being offered $500 and hotel rooms to give up their seats on an over booked flight yet no compensation or accommodation was offered for the delays I had been through. When asked point blank if I could have this same offer I was suddenly found to be able to fit on the next flight. Overall extremely flustered with united"

Pros: "Good"

Cons: "three and a half hours late"

Pros: "The flight to Mexico was great. Great service. Very comfortable ... Excellent ticket agent in Columbus. Prompt fights."
Cons: "During my check in process in Cancun I encountered the single worst airline employee in my extensive travel history. Guillermo Delgado is the most rude, demeaning, aweful person of any airline. When he wasn't roaming the line of ticketing agents kissing the female agents and flirting he was talking on his radio all the while the other agents were processing 10 customers or more to his one. Once we finally got to our turn he was rude and demeaning refusing to check are bags unless we paid him extra money despit being presented with out confirmation stating the first bag was included as it was an international flight. He demanded money under threat of arrest by Mexican police which he stated were his close friends. After buying the bag fees on my credit card he demanded additional funds in cash. Again under threat of arrest. He then stated he would not allow us to fly if we were not immediately compliant which we were. He finally gave us boarding passes and we escaped Mexico ... We will never return. We have traveled the world and never experienced anything like this."
