Pros: "Arrived on time despite late departure"
Cons: "Bumpy ride in CLT but uncontrollable"
Cons: "Very cramped seating This was an American Airlines flight, not Alaska Air."
Pros: "Do you really think there is anything to like about flying these days. We are sardines pack on a your planes."
Cons: "Purchased business class seats, boarded in group 5. Had no where to put my 1 backpack. All the storage up front was gone. Why should I pay extra for a seat if I have to wait for everyone to get off the plane so I can go back 10 seat rows to get my bag. Dirty tray tables."
Pros: "WiFi was on the flight. Free with TMobile."
Cons: "Easy and fast flight"

Pros: "The premium economy service was well worth the extra money. The crew was attentive but not annoying on an overnight service. The food was much better than other long haul internationals. And we arrived rested ready to see the city"
Cons: "Again boarding was just a mush of people. American keeps revising the boarding process but does little to make it actually efficient and orderly. The grouping should have made things better but gate agents don’t consistently reinforce the policy so passengers are all lax."
Pros: "Got us home finally"
Pros: "Flight crew very friendly."
Cons: "No entertainment so 1 star rating. Kind passenger switched seats so I could sit with my husband and son. Would have had to sit behind them if not for her. Paying extra for isle seats was a surprise."
Cons: "Wish they had told me there was a shuttle to other side of airport. Had not been to this airport in many years."
Pros: "We arrived on time."
Cons: "These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away."
Pros: "Flight and landing were smooth."
Cons: "Touch screen worked sporadically. Wifi never worked. Boarding plane was very unorganized."
Pros: "Food and entertainment was excellent"
Cons: "One checked bag was delayed in arrival"
Pros: "Other passengers were friendly?"
Cons: "I was traveling alone with my tired, cranky 13 month old. I get that it's no fun for anyone, including me, to have a tired toddler on the flight! But from the moment we boarded the flight attendant was unfriendly and unhelpful. I asked for help putting a heavy bag in the overhead compartment. She half-heartedly tried and then told me it "didn't fit". By simply turning it on its side, I was able to easily make it fit, but it was uncomfortable for me to have to do so while also holding my baby! The flight attendant then commented that I couldn't have the child in a carrier during the flight (something I am well aware of!). She also neglected to offer us a snack later on. Overall, she was rude and inconsiderate and made a difficult trip more unpleasant."
Cons: "Super old planes, no had a tv."
Pros: "The PWM airport, ALMOST makes air travel tolerable. Great little airport. Crew was pleasant, Seemed to enjoy their work. That, alone makes a huge difference in an industry that truly doesn't put customer service anywhere NEAR the top of the priority list."
Pros: "The British Airways flight to Europe had on-demand movies, with a screen on the back of the seat in front of you. The American Airlines return flight only had a cabin screen, where everyone watched the same movie. I will say, however, that the two movies I watched were excellent, so the outcome was fine (but given the option, I'd take the BA option of on-demand viewing!)."
Cons: "The seats on the AA weren't quite as comfortable as the BA flight (seats sat pretty straight upright, and not too plush... but all in all, not terribly uncomfortable)."
Pros: "Flight was on time."
Cons: "Seats are uncomfortable, too narrow, and little leg room."
Pros: "Actually coming home was great. Thank you"
Cons: "Going to Cancun. From Boise sucked. Are flight from Boise sucked we we're 4 to 5 hours late due to the gas contamination in Boise and we weren't informed until a hour + after from the time our flight was suppose to go out. We weren't very happy. They new the night prior, so we could have came to the airport 3 hours later and been just fine. Which also made us miss the connecting flight"
Cons: "Small plane with no leg room"
Cons: "AA worst airline People They have working in SFO Incompetent Rude Useless"
Cons: "Flight was good until, after arriving 30 minutes early to PWM, our plane had to wait about that much time for our gate to open. Once pulling to the gate we waited another 15 minutes for someone to figure out the walkway and open the door tom the plane-- all with no communication from the crew."
Cons: "i decided to purchase a separate direct flight at a different time instead of changing my flight, only to be informed later when i tried to hop on the back end of my original flight, that they had canceled my ticket since i hadnt boarded on the front end of that flight. i had spoken to a customer service rep about my option before purchasing the extra ticket, and she did not mention that this would be an issue. then i had to pay extra to get back on my original flight."
Cons: "Me cambiaron de asiento arbitrariamente, yo hice check in 24 horas antes para escoger los asientos que me acomodaban a mí y mi acompañante de 12 años ( los primeros) y resulta que por un cambio de avión me dieron los últimos al lado del baño. Lo que fue horrible, el olor, los pasajeros haciendo fila al lado de mi asiento todo el tiempo, sin poder descansar o estar tranquila. Comprendo que pueden haber descompuestos en el avión y cambiarlo por otro pero al menos al re asignar asientos deberían ver los lugares iniciales que tenía cada uno y no dejar a quienes habían solicitado con anticipación los primeros en el último, literalmente en los últimos puestos. Además la comida es bastante mala."
Pros: "Quick and easy"

Cons: "I never even made the flight because they kept jerking us around"
Cons: "Uncomfortable; charged $50 for checking bags only to see them checked for others for free at the gate. Seat selection on our three flights that day were ignored on 2 of tge floghts."
Pros: "Just wish the boarding was better"
Pros: "Easy upgrade"
Cons: "E145 don’t have room for carry on. Instead of people having to wait at exit of plane. Tell them well a head like when booking check your bag and make that one free. It goes to the same place right?"
Pros: "the crew was nice"
Cons: "We had to sit on the tarmac and deplane just to get onto another flight where I no longer had any power to charge my devices"
Pros: "Great to be home in time"
Pros: "Crew was very accommodating in light of the maintenance delay. Especially for those of us with small children."

Cons: "Horrible experience. Plane had an engine issue and ended up being delayed for so many HOURS that we had to sleep in Houston. The organization was a big mess - so poor that we reached the hotel only at 130am while we had to wake up at 4ish am to be at the airport again by 5am."

SO WE WERE TOLD TO SEND THEM DIRECTLY TO OUR FINAL DESTINATION. WHEN I BOARDED THE PLANE I COUNTED 7 OVERHEAD STORAGE BINS ON THE OPPOSITE SIDE TO MY AISLE WHERE I WAS SEATED WERE NOT FILLED AND THERE WERE SEVERAL SUCH BINS ON MY SIDE OF THE AISLE (I DID NOT HAVE TIME TO COUNT THEM BEFORE I SAT DOWN). I ASKED AN ATTENDANT WHY THIS WAS SO GIVEN WE WERE TOLD THE BINS WERE FILLED JUST AS WE BOARDING FROM THE DEPARTURE AREA. SHE WAS POLITE AND SAID SHE WASN'T SURE ABOUT WHO MADE THE ANNOUNCEMENT IN THE TERMINAL BUT THAT IN ANY EVENT MY CARRY ON WOULD ARRIVE SAFE AND SOUND IN VANCOUVER - IT DID BUT WITH MY BOOK FOOD SNACK WHICH i HAD INTENDED TO USE WHILE ON MY WAY TO CHI. AND VAN."

Cons: "Being separated from my wife in seating when we booked before others that we talked to!"
Pros: "The flight attendants. Especially Meagan and Heather. Amber was a,sweetheart too. I had the same attendants 3 out of 4 of my flights that weekend. So cool. When they realized it was me again they spoiled me rotten. So good I feel like unless I have those 3 as my attendants I won't fly United again"

Cons: "Really awful, disorganized and unapologetic."
Pros: "Got through sucurity ar PNR barely in time to make flight."
Cons: "Even though I am a frequent flyer with a Global Access card, I was select for enhanced security check. I paid for the Global Accessmcard especially sofas to avoid this. United said it was a TSA thing while TSA said it was at the prerogative of the airline. Why did this happen? So much for TSA Pre or Global Access."

Cons: "Flight delayed 3 times due to maintenance, total of 5 hours.

Pros: "Not a single thing!"
Cons: "Arrived late"

Pros: "The crew was nice and the area was clean."

Pros: "It use to be, I could put up with the lack of comfort and services because the cost savings made it bearable. But thes days, the basic ticket costs are high and increasing despite ala Carter pricing. The flights are always full and the number of flights are down. Airline profits are at a peak yet very little is flowing back to improve the flying experience."

Pros: "made good time."
Cons: "they lost our luggage on the way back,Didn't make it to Portland. But it was brought to our house at 7:45. I think for 1600.00 for tickets you should provide pretzels. That would be great. Thanks"
Cons: "Canceled flight, booked me an impossible connection, put on stayby when I get the tickets months in advance. Offered no vouchers and made me fly out on a diffrent day. Hs aircraft delays on all flights"
Cons: "Never flying United again. On my way to the airport in Portland I got a text from United that my flight to Newark had been cancelled and there was no way to fly me out of Portland to San Diego that day. My sister had to drive me to Boston so I could catch a flight to San Francisco, which took 6.5 hours because it flew over most of Canada for some reason AND had three babies that cried from start to finish. Oh and because I was a late addition, I had a middle seat. The second I turned my phone on after we landed I had another yet another text from United saying that my connection to San Diego had been delayed three hours and wouldn't take off until 11:15 pm."
Cons: "Tried to get assistance at the United desk where my gate was located at and they could not answer any of my questions and would not assist me or many others who had the same issues."
Cons: "Payed to upgrade seat was not comfortable and person next to me kept moving onto my side. Flight was 2 hours late so I missed my connection and had a terrible time to find a flight home. United staff was not helpful and kept telling me to go somewhere else for help. No food was served only tiny packet of way too spicy pretzels. Sat on the runway for an hour. Flight crew said 15 min and it was much longer. Crew seemed to be really confused."
Pros: "Polite staff"
Pros: "The crew communicated well to the passengers."
Cons: "I didn't get to Chicago until close to midnight, the flight to MSP was cancelled, and I missed my meeting the next morning. I understand you can't control the weather, but that didn't change the outcome for me."
