Cons: "No free wifi."

Pros: "The entertainment options and noticing the little touches that Delta is making to improve the brand and experience."
Cons: "Seems like there are legacy "attitude" issues with the crew. I sat on the aisle yesterday, and SEVERAL times I was bumped, quite rudely, by passing crew. In one instance, as they passed to pick up trash, they took two of my three items. They started walking on, and I tapped them as they passed to pick up the third. She brusquely turned and said: don't touch me to get my attention. No please; quite rude, and unnecessary."

Cons: "Delayed"

Cons: "Delays sucked."

Pros: "Highly skilled pilot."

Pros: "Friendly crew"
Cons: "Crappy food, not even outlets for laptop chargers for those who need to work during a 5-hr flight. Barely stacks up to delta or JetBlue, won’t be flying American again anytime soon."

Pros: "Flight attendants"
Cons: "VERY cramped"

Pros: "The flight crew was quite lovely."
Cons: "People all over the coach section were complaining about not being able to sit together. Families with babies, couples, even ours (though the kids are old enough for me not to be truly worried as some were). Somehow reservations seems to have messed up an entire flight. We gave up trying to fix it for fear they would make it worse. Then the woman at the gate tried to get folks to volunteer to give up their seats on an overbooked flight. But she was screaming at us. Unbelievably unpleasant to be yelled at over and over again and told we could lose our seats. The poor weather likely caused flights to be rerouted into PHL so our flight out to SFO ended up 1/3 empty. FABULOUS. But the gate experience was horrible and the legroom, had it been a full flight, was miserable. I'm in search of an airline with a humane approach."

Pros: "Made it home."
Cons: "delays."

Pros: "The flight crew were absolutely marvelous and were wonderful on board."
Cons: "British Airways had too tight of connections on flights that we purchased and then they ran late. Because of this, we had to rebook both going to Europe and coming back. Our friends were then charged extra luggage fees when being put on a domestic flight back home after going through customs. It will be difficult for me to want to use British Airways again because of all the flight change notifications we got before traveling and then once we did actual travel."

Pros: "The films available were okay, but we had to watch them on our phones."
Cons: "Moved our gate twice, both times the AA boarding crew laughed at the anger they’d caused among the upset passengers. They were also not vocal about the gate changes until pressed. We were asked to sit by the emergency gate as able and willing humans unaware it was placed beside the center bathroom.. so unpleasant."

Cons: "They forgot to board my laggauge"

Pros: "Not much"
Cons: "Big hassle trying to get on an earlierflight ehich originally booked."

Cons: "Aircraft at least in our section was very cold the whole flight. My young son was very cold even in a sweatshirt. I was very cold in a sweater, shirt, and jeans. I asked a crew member if they might have a blanket to cover my son, he brusquely replied “No blankets, no pillows!” So we just froze for 5.5 hours."

Pros: "Flight attendants actually seemed to care about what they were doing. Seats were pretty comfy for once."
Cons: "Flight delayed with no explanation or apologies. Putting two and two together from the airport monitors it looks like they had to swap planes due to a scheduling or maintenance issue. Just another chapter in the neverending saga of delayed American airlines flights"

Pros: "Seats were reasonably comfortable. On time departure, early arrival. Gate crews not ready in SF"
Cons: "Entertainment options good, but require download of a proprietary app. Quit trying to sell us credit cards! Should get more than a pack of cookies for a 6 hour flight."

Pros: "Things went very smoothly."
Cons: "Long layover"

Pros: "This plane had more legroom than our international flight which was strange but at least it was better."
Cons: "See prior response"

Pros: "Boarding, comfortable seats, clean"
Cons: "Mediocre service, choice of food was down to one option (and I was on the 2nd row)"

Pros: "nothing"
Cons: "no inflight entertainment no outlets"

Pros: "The entertainment selection was pretty goid"
Cons: "They made a horrible mistake by getting the bag count or weight wrong and we had to go back to the gate and it cost us 2 1/2 hours."

Cons: "Tight connection! The airlines need to Realize that a 2 hour layover is NOT enough when you have to go through immigration, customs, and security before making your next flight!"

Pros: "Flight had very few people on it so everyone could stretch out for the 6 hour flight."
Cons: "The original flight turned around 45 minutes in and I missed my connecting flight. AA refused to try and get me on another flight the same day so I could make it to Sydney on the original day I was supposed to land. We waited 2/3 hours to board a whole new flight, and AA hardly compensated. If anything they should’ve provided a meal at least instead of a bag of pretzels. Flight crew seemed very inconvenienced and it showed."

Cons: "Never got to take flight. Concerned now that I will lose EQM, EQD from flight because AA rebooked me on DL. Also, original flight was in F. AA rebooked in DL in economy all the way. So I paid F fare for economy flight."

Pros: "The boarding process was ok."
Cons: "The entertainment system failed again."

Pros: "Easy to get though security as I was pre check tashav"
Cons: "Having to spend 95 dollars for seat upgrade to be on a exit aisle"

Cons: "No electrical outlets. No monitors"

Pros: "The boarding was done well"
Cons: "This was a 6 hour flight so American could at least have offered a better choice of in flight food purchases"

Pros: "I loved my seat,with the leg rest‼️ THANK YOU"

Pros: "Landed early"
Cons: "The seats were not as good as the ones on my BA flight to Heathrow and then Rome. Also, cross country flight but no in flight entertainment. Arrived early in PHL and American would not let me move up to an earlier PHL-SFO flight since it was a code share booked with BA. Should not be my fault as when booking it indicated all four of my flights were with BA. Once booked it indicated the return flights were code share with AA. American should have allowed me on the earlier flight. That would have opened a seat on the scheduled flight which had people waiting on standby."

Cons: "Made me check my bag saying the flight/overhead bins were full and when I got on the plane- there was at least 15 overhead bins wide open (even above my seat). This is ridiculous after flying for 15 hours."

Cons: "It was advertised that one can see entertainment through WIFi, but from my iPad, i can't connect to this WiFi. I tried several times until I just gave up."

Cons: "Seats were quite uncomfortable, there was no entertainment options, there was no way to charge any electronic devices because the plane was so old, which meant I almost wasn't able to catch a ride home after the flight. For a cross-country flight, I would expect a better experience."

Cons: "No leg room"

Pros: "That we arrived safely and on time"
Cons: "The food was horrible for such a long flight and the seats were uncomfortable. Most airlines have neck braces to place one's head on. Neither flight had anything for one's head. I had my own blanket fortunately because it was cold...then hot... If one did not have an iPad or computer watching anything was impossible on a 6 hour flight. Never going to take this flight again aGAIN...NEVER PAID ADDITIONAL ON SUCH A LONG FLIGHT FOR SEATS. NEXT TIME I'LL STAND."

Pros: "extra leg room but I had to pay for it"
Cons: "This should only be used for important communications. And to not offer food on a 6 hour flight is horrible."

Pros: "Took off and arrived on time."

Pros: "Actually had leg room on these flights and was pretty comfortable. Excellent crew, food pretty good too on the first leg."

Cons: "For a flight five hours or more I was disappointed that there was no complimentary food. It otherwise it was fine"

Pros: "No entertainment nothing"
Cons: "Nothing"

Pros: "I can't comment on food or entertainment and there is no N/A option. I did not purchase food or use the wifi for entertainment. The seat I upgraded to was comfortable and spacious even if it didn't recline (I sat in front of the OWWE)."

Pros: "Pilot did a great job coming into SFO airport. Had to abort landing and do it again."
Cons: "Unless we slept through it, no food or snack was served. It was a 6+ hour flight. I was awake for water and soda offerings but not even nuts. To be fair, I may have been asleep but I woke up every time a drink was offered. We came from a connecting international flight with no time to get a meal. We grabbed a bagel as we rushed through the airport. I didn't pick the flight so we couldn't have more time."

Pros: "Flight on time. Crew were pleasant."
Cons: "Usb charger would not charge tablet in flight. Tried multiple sources since there were 4 of us-none worked."

Cons: "Same as above"

Pros: "Nothing absolute nightmare .. no water .. are you serious"

Cons: "The flight was delayed, the ground staff made no effort to update its passengers as the mood to grow angry, however instead two of the counter people continued to laugh joke and talk between themselves as everyone grew more and more restless by 6:30pm"

Pros: "Old plane"

Cons: "Crew was not skilled or kind in dealing with others around me. Had the finesse of a frustrated 10 year old when asking other to check their bags."

Pros: "on-time"
Cons: "crowded, tight even in better seat, no wifi entertainment"

Cons: "No entertainment at all for this cross country trip."

Cons: "Seats need to be bigger (wider)"

Pros: "Comfortable plane. I love United Express."
Cons: "Nothing."

Pros: "Have seatback TV and arrived on-time"
Cons: "Sitting in window seat"

Pros: "Flight left on departure and on board air cooling system was much welcome. Cabin crew were polite."
Cons: "Cabin was untidy, goodness knows what was stowed away at the back of seats towards the rear of the cabin, so rear of cabin was unwelcoming. Cabin crew should keep some overhead lockers for their own use. Poor sound quality on Inflight entertainment, either that or Headphones were poor. Food portions were painfully small (lunch of chicken risotto) AND I found pretzel flavoured breakfast bap unpopular."

Pros: "Read above"

Pros: "Sucked"
Cons: "On time, free food and WiFi for our troubles and serious delay, our money back."

Pros: "Boarding was great"
Cons: "Inflight Services was horrific and my stuff was damaged in my luggage."

Cons: "Food ran out and only one choice"

Cons: "The fuel mishap made us late which is just not ok.g get it right."

Cons: "Delay for 3 hours"

Pros: "Boarding was smooth and took an average amount of time. We arrived exactly on time. Staff were all friendly and helpful. Plane was clean.. overall very pleasant !"

Pros: "So many regrets for flying this dumpster fire."

Pros: "Flight wasn't full so got to sit w/o middle seat psgr."
Cons: "UA app for in flight movie kept losing contact or sound."

Pros: "Stewardess was nice"
Cons: "Delayed, then when we got here no lanes to land. Seats are way to small for normal sized people."

Cons: "Just give free wi fi already"

Pros: "My flight stopped for over 2 hours for refueling which caused me to miss my coneccting flight, plus 2 other reschedual flights. Then no one would accomodate me on account of this. Never flying united again"

Pros: "Seats are comfy"
Cons: "Food service sucks"

Pros: "The crew did the best they could with what was presented."
Cons: "Pilot should of gave us accurate times rather than saying "we should be taking off in another 15 min folks" which turned into 4 hours, pretty crazy."

Pros: "Crew very friendly!"
Cons: "No entertainment (video screens ) on board flight."

Pros: "It was a light flight, so I could have my carry-on with me even though I was in group 5. The breakfast -- berry pecan French toast -- was surprisingly tasty and satisfying (if not very attractively presented)."
Cons: "Too bad I had to pay so much for the exit row seat. I'm tall and it's needed for standard comfort (as opposed to extra comfort). Oh well. Gotta squeeze those dollars out of the passengers every way they can."

Pros: "The boarding was very smooth."
Cons: "The passengers behind me had a baby on board that cried throughout the whole flight."

Pros: "Got me safely to my destination. Other passengers were friendly and helpful. Sf and Vic airports nice. flight attendants passably pleasant. No food that I was aware of. Entertainment at least there was a wifi option since there were no screens."
Cons: "Check in agents all might as well have been robots, but with bad attitude. Even at the star alliance gold checkin desk the agent was clearly unhappy/furious (seem to be ongoing issues with the system/ machine frustrating him) and was consistently abrupt and cold though our interaction. He did help by lifting bags onto weigh and to press buttons to get the tickets issued, but I would have a much better experience of United if he has shown any sign of warmth or even smiled. I was struggling with a baby in a carrier, and several suitcase, and he didn't show any sign of humanity. The guy who labeled our bags was a bit nicer. The team overal though just barked instructions at the customers, never looked them in the eyes, and seemed to all hate their jobs. We got our boarding passes issues successfully, yes, but I felt on pins and needles like I had to be very careful not to offend anyone.... Which I don't think is what you want your passengers to feel at the start of a flight."

Cons: "The seat cushions were in terrible condition!!!"

Cons: "Cross country flight, tiniest snack ever, $8 for any entertainment. Choose JetBlue if you get the choice"

Cons: "Every time I fly through San Franscisco, my United flight is cancelled, delayed or I get stranded! If you know a large number of your passengers are coming in on a flight from the east coast that was delayed for de-icing...wouldn't it be easier to just hold the flight, since it is the last flight of the night. United's customer service and care of passengers is horrible!"

Cons: "delay service is really bad cant find my baggages"

Cons: "TV was broken"

Cons: "Over a hour and a half late leaving portland"

Pros: "Wish there was complimentary snacks ie peanuts or crackers"

Cons: "Not enough food at all"

Pros: "It was easy, fast, & simple."

Pros: "My overall experience was excellent except for your new food policy. Meals should included! I am handicapped and asked for help boarding and getting to flights! I was helped by your caring and very curtitious staff! Thank you for your help."

Pros: "On both departure and on arrival. Lack of training? Bad attitude? Whatever, it was amateurish and annoying."

Pros: "No problems whatsoever."
Cons: "Traffic getting to the airport."

Pros: "Inexpensive"
Cons: "Seat extremely uncomfortable for a person my height (6') and not adjustable in any way. Not a ton of leg room either, though not noticeably less legroom than other airlines."

Cons: "Not enough staff in the boarding area to ask about luggage etc"

Pros: "Everything"
Cons: "Nothing"

Pros: "Delay for too long. It took so long after landing! What are the ground crews doing?"

Cons: "We were stuck on the runway for over an hour after we landed and getting our luggage was a DISASTER. They changed the location of our baggage claim carousel with minimal notice, only to change it back to the original carousel with NO NOTICE. It took over an hour again for our luggage to come out and it trickled in so slowly, that I ended up getting my bag a full two and a half hours after we landed. Awful experience."

Pros: "Not"
Cons: "Everything . Plus they lost my bag. Will neve fly Frontier again."

Cons: "Charged me $200 for name change that I did not nerd"

Pros: "I had a baggage that met the online specifications- 14X8 but they still charged me $60 because it was not a "personal bag" -- they kept referring to it as a carryon."

Cons: "I wish you will take cash payments for meal purchase"

Cons: "This airline comes up with every idea possible to charge the costomer. I give the airline a star for being sneaky and sly and having rules and policies to rip off passengers. Because it is brilliant that they con you without breaking any laws."

Cons: "Bag fee is expensive."

Pros: "Cheap, until you had to pay for bags and drinks."
Cons: "Had to wait for over 1/2 hour to disembark."

Cons: "Frontier nickles and dimes you."

Pros: "And it was cheap"

Pros: "Very informative on where to go!"
Cons: "Not very informational on security policy"

Cons: "Paying for a seat assignment on line before going to airport. Baggage charges too high. These extra costs added an additional 49% to my ticket. Unhappy with your airline"

Cons: "The Chicago airport was terrible both times. Things not clearly marked. Staff not friendly or available. Long term parking very hard to find and pricing very unclear. Didn't realize we would have to pay additional for just a seat and carry on luggage"

Cons: "More delays, few answers, no satisfaction. Do whatever you can to avoid flying Frontier."

Pros: "Everyone were really nice. The service was good."
Cons: "I didn't like the following fact. I was charged $35.00 for a carrying on bag. When the bag met all the requirements needed for a carry on. When other customers had larger bag and they were not charged. The bag was small enough to fit under the seat. I should be re-enburse the $35.00 I was charged. Thank you"
