Cons: "Our luggage was lost upon our return trip. While helpful, they didn't automatically offer a customer service gesture discount without request. This was mentioned upon disembarking from the jet. However, the claim attendant did not mention it at customer service to my wife. I had to go and mention what was stated by the flight attendant. While waiting again in line, I observed that the customer service person did not mention it to the two families in front of me."

Pros: "On time. Friendly staff."

Pros: "Quick flight and the staff were awesome."

Pros: "Not much."
Cons: "Flight was oversold from the get go so there was a constant request for volunteers to take a later flight and voucher. At boarding time it was announced there was a mechanical delay for 30 min. Then another 30 min. Then another 30 min. Eventually it was announced that another plane with 20 fewer seats would be used and volunteers were requested again. After being awake over 24 hours a very miserable end to a trip."

Pros: "The staff was great."
Cons: "We went through very serious turbulence. The landing was very rough."

Cons: "Traveling alone with my 7 mo infant. Boarded the plane and got all settled for our quick flight, just to be told that we all had to deplane due to mechanical issues. So, had to pack up all our baby stuff, grab our gate checked car seat and stroller, go to another gate, and board again. After taxiing for about 40 min, we finally took off (when we should have been landing). Definitely prepped bottles and diaper bag for a one hour flight and had an antsy baby by the time we landed. Totally understand that mechanical issues come up and am glad we were safe, but would have been much appreciated if we didn't have to board, deplane, and then board again."

I was happy to do what they said, but it would be nice if they were more consistent about the bag sizes. I didn't have this problem on the way back to Seattle though."

Pros: "Free Movie selection; plag in devices"
Cons: "Nothing. Everything was great"

Cons: "30 min delay"

Pros: "Everything"
Cons: "Everything"

Cons: "Ok, crew was ok, we arrived an hour early. Everything else was terrible to bad. No food in 6 hr flight?! Given a single tiny bite sized cookie, and only 2 small glasses of water, soda or juice. I'm a tall size 0, who still found the seats uncomfortably tight. WIFI was not included. We had to pay & pre load their app before the flight. Costumer service gets 2 out of 5 rating, giving 1 for showing up 2 for being dolled up"

Pros: "Everything went perfectly. Great price."

Pros: "We needed to switch our two flights from different times and from having a layover to a direct flight and they were willing to do so without charging additional fees. Great customer service."

Cons: "delayed"

Pros: "Staff was friendly not to helpful"
Cons: "I wish staff would allow moms flying with small children to get their check at the gate items first before single traveling adults. So moms don't have small children wondering around the Tarmac while the mom trying to watch them and fight through a crowd to get car seats and bags."

Pros: "Entertainment was awesome. Although airlines are stingy with snacks, Delta had a good overall selection and very generous."
Cons: "Something that cant be changed overnight, however, there should be a little more Aisle space for folks pass through as my shoulder was getting beat up after every passing person and cart."

Cons: "SeAts"

Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"

Pros: "Fly attenden alwas with a beautiful smile"

Pros: "Nice plane, comfortable accommodations, great crew."
Cons: "There was anything I didn’t like about the flight, everything was great!"

Pros: "Nothing particularly stands out. I did arrive safely."
Cons: "First class did not come with lounge access? Drinks were not cold. Bathrooms were falling apart and came with a disgusting odor. Time to retire these aircrafts."

Pros: "Flight attendants were nice based on the situations beyond their control."
Cons: "Flight was delayed for about three hours, due to mechanical issues with the second engine not starting. We sat on the the plane for over an hour and half. Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."

Cons: "Tv"

Pros: "The chekc in person was very helpful."
Cons: "The plane was too hot and the pilot did not accommodate the passengers request. More than just me made the same request."

Pros: "That I landed safely"
Cons: "1st class was horrible."

Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"

Cons: "Delayed two hours"

Pros: "Flight was faster than expected, comfy seats, check in was fast and easy."

Pros: "Got to my placs"
Cons: "Lol put the two fattest people next to each other"

Pros: "Above feedback is for the MSP to GEG flight"

Pros: "The fact that there were no snakes on this plane :-)"
Cons: "Same issue... there were no snakes on the plane :-/"

Cons: "We were delayed due to the air conditioning not working. So, it was a tad warm in the cabin. It would've been nice to have someone coming around with water making our delay a little more comfortable."

Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."

Cons: "There delay"

Pros: "On Time"

Pros: "On time"

Pros: "The crews were very friendly and everything went as planned. It was a nice flight."

Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."

Cons: "Never again!"

Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."

Pros: "Everything was great"
Cons: "Nothing everything was fine"

Cons: "paying extra for leg room and checked bags"

Pros: "Very late flight. Left on time, arrived 25 minutes early! Cabin crew were friendly and cared for everybody's comfort. They distributed a lot of extra munchies. They had real almonds instead of the usual 1/3 ounce peanuts, isn't that wonderful? Lights went off early and stayed that way so that the passengers could easily sleep through the flight. Uneventful flight, and therefore enjoyable."
Cons: "I had chosen 10C in the Comfort+ section of this MD90 plane. I did get my knee bumped more than once. I still like the seat because I can stretch my legs, but people should be aware of the bumping issue; it can be rather painful, and you do not get an apology."

Pros: "Got delayed due to the computer shutdown"

Pros: "Nothing"
Cons: "Being scammed by the Chinese, China Southern"

Cons: "My seating. Location. We checked in 22 hrs before the flight and received C4 c5"

Pros: "Relatively painless."
Cons: "I do not like the seating and the need to be on a regional jet for more than an hour. Delta should think about passenger comfort when they consider their bottom line. You'll lose me as a customer."

Pros: "Smooth flight, friendly attendants. We had exit Sears so great legroom."
Cons: "Sears not assigned until boarding."

Cons: "Early morning flight. Sat near front cabin. Could not sleep as crew was talking the entire flight."

Pros: "The crew was super nice, they offer me to change my seat to fly with my sister."
Cons: "The pilot"

Pros: "It got me to my destination safely."
Cons: "Very abrupt service. Not much room."

Pros: "Crew were amazing"
Cons: "WIFI please for the god sake it’s a transatlantic flight"

Cons: "Delayed 1.5 hours each way for maintenance, did not allow us to switch seats to sit together previously at flight and the flight was very empty. Very uncomfortable seats. Will not fly AA again"

Pros: "787 seats have better legroom & recliner"
Cons: "Vegetarian food needs lot of improvement"

Cons: "My tray table was dirty. It had crumbs on it. The flight was on time which was awesome."

Cons: "The seats are extremely restrictive and in a aisle seat I had the gentleman sitting next to me with thighs touching and attendants brushing by me as I squished to left to avoid contact with him. Entertainment screen between center seat and window seat so I just didn't even try to look at it and mostly just leaned forward to have a little space. Also another inch or 2 was taken by person in front of me putting their seat back. With such restrictive space why is this even possible??? Flying has become ridiculous and I try not to as much as I can."

Cons: "We landed early but the plane was late 50 minutes into gate. Plane went pst our gate twice, just driving around the terminal."

Cons: "Too small of a plane for that long a flight. Cabin was too damn hot."

Cons: "I'm expecting more from AA. We were delayed for 2.5 hr since we didn't have a pilot !!!!!"

Pros: "Everything was about average, nothing amazing, nothing bad"
Cons: "The WiFi could have worked better not have been so expensive"

Cons: "Speaker volume was too high."

Cons: "N/A"

Pros: "On time"
Cons: "Tiny seats, no snack or napkin with the drink. Noise in back."

Cons: "Too bad you paid$$$$ and they give you pretzels"

Cons: "Small, cramped seating"

Pros: "The flight was on time"
Cons: "Tiny bathrooms"

Pros: "Wasn't full, plenty of room. Free booze offered!"
Cons: "Delayed, crew didn't help couple to calm their children and restore morale"

Pros: "The flight crew was very friendly"
Cons: "I wish the flight was longer. :)"

Cons: "The flight was delayed an hour (which wound up being a 3.5 hour delay in total, with all the continual delays that pursued afterwards(, which would have made us miss our connecting flight back to our home destination. We switched flights in order to make it home at a decent hour and not spend our entire day and night in an airport. We arrived home and they did not transfer two of our three checked bags to our flight, thus making it highly inconvenient upon our arrival home with no luggage."

Cons: "The male flight attendant was incredibly rude, kept hitting my arms with his body with zero apologies. No manners when taking food and drink orders. Did not seem like he liked his job and in a customer service atmosphere this was extremely disappointing."

Cons: "Poor seating and lost my bag."

Pros: "The flight was as advertised. Nothing particularly special other than reliable which was just fine with us."

Pros: "Plane was new and entertainment was free. Great service too."
Cons: "American has improved a lot"

Pros: "Its Alaska. Nothing more to say. My preferred airline and never had a bad flight."
Cons: "The usual. More legroom would be good. That's about it."

Cons: "You pay extra to get the TSA Full background check, so you can breeze through TSA, with PreCheck, yet this Airline has a problem with recognizing it. 3 phone calls layer and a Visit to their Costumer Serice Desk, and none of them can figure it out. Uhg again."

Pros: "Everything else was Fine on the flight..."
Cons: "...But having HBO NC-17 available on a public flight is uncalled for. Even though screens employ technology limit viewing from the side, the seats behind can see everything. We were thankful none of our kids were on this flight. Gratuitous sex scenes in abundance. No thanks American."

Cons: "Seat in front of me was broken in the reclined position so I had no leg room."

Pros: "The seat pockets were decent, though I like when the magazines have their own designated slot behind the tray in addition to a pocket. Also good there were power outlets. I liked that they didn't skip row numbers, including 13. So if you're in row 22, for example, you know that's literally how many rows back you are."
Cons: "It took 25 minutes from when plane landed until it reached the gate. There was also apparently an issue with the auxiliary power -- the lights went out in back half of plane when we arrived at gate. I prefer having a screen behind each seat, rather than those attached to ceiling on this flight, so that the entertainment can be customized."

Cons: "Plane had no Per-seat entertainment system."

Pros: "The entertainment"
Cons: "There was nowhere to stow my purse and things i wanted to use during flight near me, my luggage got lost"

Pros: "Biscoff!"
Cons: "lack of ent. options"

Pros: "Boarding process and flight crew were just fine - nothing excellent, just average. The plane was an older model, nothing special. We arrived 10 minutes early but then had to wait 20 minutes for a gate."
Cons: "They had no alcohol and no entertainment on a Transcontinental flight from IAD to LAX. Also once we landed we had to wait 20 for a gate assignment."

Pros: "entertainment displays on the back of every seat headrest. Nice room on Main Cabin Xtra, even with someone in the middle seat."
Cons: "1 of the flight attendants was pushy(older caucasian lady)"

Pros: "Flight got to gate 15 earlier than scheduled."
Cons: "But took one hour to get gate checked bag, which was mixed in with checked bags at bagged claim."

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"

Pros: "I liked that the plane was clean, that the staff consisted of somewhat normal, more mature people, and that water and carry-ons are free."
Cons: "I felt that having to pay $50 extra for a seat when I checked in was pretty deceptive and unethical. I think most people would agree that when they purchase a boarding pass, it is assumed that it includes a seat. Having to pay extra for a seat was something I did not plan for and it was out of my budget, but I had no choice, because I had to get home somehow! I'll be going without groceries this week due to this unplanned expense."

Pros: "Comfy seats, great service, was a smooth ride"
Cons: "my entertainment system wasnt working, the headphone jack was not working at all."

Pros: "Boarding the plane from the back first saved longer queues. Unfortunately people cheat and the boarding officers don't send them back to the right queue. Toilets were clean. Staff excellent. I was glad all my flights were stuffed to the gunnels. Presumably that is best for the environment rather than lots of planes with fewer passengers in each."
Cons: "Passport control with new computer ID checks was fast. Baggage was slow coming. I booked through Netflights and they didn't book me a good seat. If I could have changed it myself they should have told me. On the way to Tampa on 3rd March I couldn't check in within 24 hours and had to wait half an hour while they changed our plane. BA used to do short science programmes which I loved. Shame these have finished."

Pros: "Flight was delayed and hour and they lost out baggage. Did not have clothes for 2 days"

Pros: "Friendly, helpful flight attendants. Flight left and arrived on time, despite being completely full (asking for volunteers to bump). Offered to gate-check our carry-on bags for free to alleviate crowding of overhead bins was fine for us since we already had checked baggage."
Cons: "If you don't pay for the premium seats, the legroom is pretty tight. I'm only 5'8" and I felt it -- if you're 6'+ you better pay for it. This aircraft had screens, but not individual ones so you're stuck watching whatever sitcom replay they pick, although there is a moderate selection of other music. I've been on a newer aircraft with the in-seat power and interactive screens so I know how good it can be, so this was a little disappointing."

Cons: "The counter manager at PHX, Lanell Monarrez was a total witch and whispering to Lanya in front of me was very unprofessional. I paid a full fare 1-way ticket to get out of PHX as they were not willing to allow me to fly standby or make a change to my existing ticket. Crappy airline service at the counter. Good flight crew."

Pros: "Crew was great"
Cons: "For price paid, service and treatment not comensurate expense. Boarding system seems arbitrary to seat booked. Had window seat but middle and aisle seat boarded first...doesn't make sense."

Pros: "Nice aircraft, clean, comfortable, friendly staff"

Pros: "The air hostess gave me extra pretzels"

Cons: "Each flight delayed at least an hour"

Pros: "I did like sitting on the left side of the plane. There's a little more room. I feel it's horrible how the airline charges so much and cram so many seats in one air craft. Making it a miserable flight."
Cons: "See above"

Cons: "no food"

Cons: "Noisy/ squeaky seat"

Pros: "Thank you for making this connection available from charlottesville to dulles. It beat driving! Everyone was helpful"

Cons: "The lack of breakfast options. Lack of room."

Pros: "This plane was smaller so I got to sit by myself so it was more comfortable for me"
Cons: "Lack of drinks/ comp snacks"
