Cons: "Snacks if possible"

Cons: "horrible boarding management in SJC."

Pros: "Bags arrived on the belt quickly"
Cons: "Why is there not saying precheck to use after you've been funneled through customs? ATL is advanced enough to have kiosk for arrival, even for those confused and not with global entry, but then forces you to wait in security line instead of the typically faster tea precheck line. Every minute I'm in line, I'm not spending money"

Cons: "sat on tarmac for 45 minutes! AFTER landing... unacceptable."

Pros: "comfortable seats"
Cons: "food"

Cons: "Seats are far too cramped for someone who is 6,2."

Pros: "I had nice leg room as I was in the exit row"

Cons: "PAID FR UPGRADDED SESTS AND THEY WETE GIVEN TO LATE ARRIVALS."

Pros: "Other passengers"
Cons: "It was terribly hot and the attendants didn’t serve us regularly. The skipped us when we wanted cold water:"

Cons: "Entertainment arm rest did not work, flight attendants we're not very attentive to used items left on tray s to pick up. Empy cans ad wrapper s say for 3 hours before being picked up. Middle rest room was left very dirty due to bad hygene of passengers."

Pros: "Friendly Staff"

Pros: "Both the departing and returning flights departed in schedule and arrived a solid half hour early. Staff was accommodating and friendly, and very helpful with me juggling luggage and a toddler by myself."

Pros: "seating assignment"
Cons: "wish the crews were more pleasant. some were pretty rude to some passengers"

Pros: "The aircratf and on time operation"
Cons: "Gate agents not following AA.com policies to charge extra fees"

Cons: "No outlet and waited idle for a long time before getting to get off plane also had to walk my bag back bc there was no overhead storage space in the bins which prevented me from getting off the plane sooner"

Cons: "The bathroom supplies were not replenished. In fact, the facial tissue was empty at beginning of flight. When the toilet paper ran out, I finally informed the attendant and they fixed everything. It seems that checking on that stuff was not part of their routine."

Pros: "The flight crew were amazing!"
Cons: "Gaye agent refused to let me take my medically necessary medical equipment and meds on board. She refused to look at my Dr note that TSA had no problems with after screening. It was humiliating and horrible!! I have a video ad well as statements on the flight from other passengers regarding how she treated me it was horrible!!"

Pros: "Early for arrival!! Love that!"

Cons: "no charging station"

Cons: "We had too little time to switch flights. We were stressed and had to run a lot in order to make it to required connecting flight"

Cons: "It took a while day to get our bags after they decided to put it on the next flight"

Cons: "Dry / borderline rude staff and hostess. Dated plane. Tiny seats. But that is pretty much the baseline of airlines in the US. When will carriers start to take note from International carriers..leaps and bounds ahead."

Cons: "close it!"

Pros: "Long walk and less than an hour. Very difficult for senior. No assistan e available."
Cons: "The pain from carrying bag between gates"

Pros: "Excellent crew."
Cons: "Obese people should have to declare their weight and pay for two seats."

Pros: "Delayed"

Cons: "Longer flights should have screens in the headrests"

Cons: "Bad as above"

Cons: "Going through immigration in Dallas is a disaster. The wait is eternal. None-US passengers seemed to get processed faster."

Pros: "seat comfortable enough"
Cons: "unbelievably tightly spaced seats. Incredibly uncomfortable to have knees pushed into seat ahead - - so tight almost impossible to get feet under seat."

Pros: "I liked nothing."
Cons: "We boarded an hour early. It was at least 80° on the plane, and then everyone got on. The crew was very rude. They ignored everyone in coach."

Cons: "Delays"

Cons: "They cancelled the flight and put me to fly the next day"

Pros: "Nothing"
Cons: "See above comments"

Cons: "The crew was talking very loudly so I couldn't sleep. It's a red eye flight! People are trying to sleep!!"

Cons: "2 different attendants spilled drinks all over me and my carry on"

Cons: "Never made it because first leg was canceled"

Pros: "Flight was canceled due to maintenance problem, American claimed rebooking was someone else's responsibility. I had to talk to 4 people before they rescheduled me for the next day. American's gates/terminals at LAX are also a pain--you never know if your flight will depart from the hinterlands of Tom Bradley terminal, or Terminal 4 or 6, which can mess you up with parking/security screening/scheduling. I will try to avoid flying American in the future. I didn't get any vouchers for the cancellation, either. BD"

Pros: "Great service. Lots of legroom"
Cons: "None"

Pros: "Was called ahead of time to e alerted to flight delay. But I'm still never flying American again due to the rudeness of the crew."
Cons: "We're asked at the gate to measure our luggage. We did, and while it fit, the material of the bag made it look bulky (but upon touch, it was clearly not a full bag). When we said that it fit; the woman literally just scoffed, said "no" rudely, and walked away. We were polite, so why the rudeness?!! Never again AA."

Pros: "Nothing...I had to be rerouted to Chicago to Seattle!"
Cons: "The fact that through no fault of my own, I arrived in Seattle much later than expected and my clients were not particularly happy with the delay."

Pros: "Nothing!!! WORST EXPERIENCE IVE HAD TRAVELING"
Cons: "This was the worst day we have ever had flying. Spent 12 plus hours at the airport! Got on and off planes for 6 hours because of mechanical problems. 7 hours later they canceled the flight due to crew fatigue. The customer service was horrible plane was dirty it was an horrific experience. Alaska booked us with American Airlines. I will never travel American ever again. I'm considering using a different booking site. The experience was the worst I've ever had. Kayak Alaska and American are getting bad marks from me!!!!"

Pros: "The plane was luxurious and comfortable, even in coach. Great flight."

Cons: "United, along with American, is a horrible carrier, and the next time it files for bankruptcy, needed to be allowed to remain our of business. The employees don't care about service at all, it's no longer part of their culture."

Cons: "Friendlier service."

Pros: "Love the ability to watch films on my device by way of United WiFi"
Cons: "Better snacks"

Pros: "Better staff"
Cons: "Still terrible"

Pros: "It was just okay"

Pros: "Brand new plane"
Cons: "Didn't get much refreshment"

Pros: "The fact that we actually left."
Cons: "Delayed and upset passengers. Bad breath from passengers circulating in the AC. FA we're okay nothing above and beyond."

Pros: "Not a lot to say really from a positive, In Europe if we had to fly over 4 hours the airlines put on larger planes, this plane was small for a 6+ flight"
Cons: "Small plane for a 6+ hour flight, food is . sub standard, if you want to watch the onboard entertainment you need to do so from you phone or Ipad, you need their app installed first and flash player, if not your screwed. They allow you to download their flash player but it does not work."

Pros: "Everything was great except for the food."
Cons: "The hamburger bun was hard as a rock."

Pros: "Every day they take more away from us....the paying customer. ALL major carriers are becoming LCC ( low cost carriers ). Are there no real domestic airlines left. I REALLY miss Continental."
Cons: "I used to enjoy flying. Now I dtead it. There is NOTHING to look forward to. These days you get to pick lhe lesser of all evils. Is there an airline out there that REALLY wants me as a customer???"

Pros: "On time"

Pros: "Service and flighr smooth"

Cons: "Delays"

Pros: "I arrived safely."
Cons: "It's a zoo. It's a DIY of checking in and checking your bags in. No staff is around to help. You are on your own. Unorganized."

Cons: "Late late late. Had to run to get my connection. Not Uniteds fault though. SFO too busy. Will avoid in future."

Pros: "The two people that helped."
Cons: "That United had NO remorse for our inconvenience and offered NO compensations."

Pros: "Everyone and everything was great"

Cons: "The cabin was too hot."

Cons: "Support for all Android platforms needs to be updated."

Pros: "Great service and food"

Cons: "Showed up at airport w 2 15 yr olds traveling alone. We're told we needed to pay $150 each way. We were NOT told when tix were purchased. Accused of lying about the girls ages when we booked. Tix were booked and paid by two different parents and times. Agent relented and waived fee. At the gate we were again challenged and had to go thru it all again. No more United for us!"

Cons: "Confusions on dates from Internet. Your site usually sets its own dates without confirming."

Cons: "delayed"

Cons: "Charge for tv!"

Cons: "Should load the plane from the back rather from the front. People in the back can sort their stuff while still be able to load people into the front."

Cons: "Having to pay for Internet sucks"

Cons: "They lost my suitcase."

Pros: "Same as above statement."
Cons: "Pilot landed the plane a little on the rough side. The Tarmac was definitely felt."

Cons: "N/a"

Cons: "Horrible overlay"

Cons: "My luggage got lost! No water offered!"

Pros: "it was very comfortable"

Cons: "No room in the seating, nor in the overhead."

Pros: "same as above"

Pros: "Nothing"
Cons: "Out of the four frontier flights I’ve taken in the past six months each one has been delayed for some reason. First one was over an hour late and caused a majority to miss connecting flights. Today’s experience was not a whole lot different. First leg of the trip was behind schedule, second was delayed at the terminal for the “cleaning” of the aircraft. I will walk to my destination before ever flying with frontier again"

Cons: "It’d be nice to have internet access, whether free or for purchase"

Cons: "Delays"

Pros: "Getting to Seattle to get away from the airline"

Pros: "They still pick up trash!!"
Cons: "New airbus has even LESS room!! Have to manhandle your personal bag out of the even smaller space under the seat! A soda is $3! There is Nothing to read anymore and the crew are overwhelmed with cranky people... making them cranky."

Pros: "The same"

Pros: "Nothing"
Cons: "Too many fees"

Pros: "As above."
Cons: "As above"

Cons: "Overall"

Pros: "I was last on and only the 1st class was open so free upgrade"
Cons: "No complimentary snacks"

Pros: "fare was good"
Cons: "the seat was terrible"

Pros: "* Good leg room at my seat * Though the check-in line was very long, the curbside check-in attendant was courteous, professional, and very efficient."
Cons: "* Long line for check in * Flight 137 from Denver to Seattle was almost two hours late * seats on airplane don't recline and there is not an adjustable headrest to hold my head in place * The flight attendant wouldn't let me put my paid-for carry-on luggage in the overhead bin above our seats (we were sitting in row 2, seats A,B, C). She said they were reserved for row 1. So I had to place our paid-for carry-on baggage in the overhead bins above row 4. * no movie or even reading material at my seat * No complimentary snack or beverage (only available for purchase). Are you kidding me? I paid extra money for carryons and check-in baggage for all three of us, and my experience on Frontier made me feel like a second class citizen. I doubt I will ever fly with Frontier again."

Cons: "Frontiers prices might look good upon booking but you are charged for everything. $45 extra for a carry-on, $2.95 for a can of soda, etc... cramped seating,"

Pros: "Ticket price"
Cons: "Add on price for everything... carry on by itself $40!! Ridiculous A fee is acceptable, but too high of a fee is ridiculous"

Pros: "Nothing"
Cons: "Everything"

Pros: "Crew was friendly and accommodating but we waited 3+ hours for a pilot that never showed"
Cons: "Crew was friendly and accommodating but we waited 3+ hours for a pilot that never showed"

Pros: "same as above"
Cons: "same as above"

Pros: "Staff was awesome and efficient"
Cons: "Food options, especially since one has to purchase snacks."

Pros: "I really appreciated the free checked bags. That helped me out a lot on my trip. Thank you, Frontier!"

Pros: "Staff was friendly."
Cons: "No food or entertainment and nickle and dimed on everything."

Cons: "From the time my flight sat at the gate for 30 minutes saying that had to load last minute bags, to getting no water to drink for 3 hours, to uncomfortable seats that do not push back, and now no bags after 36 hours after paying a $40.00 fee, with no way to communicate with the airlines for a status, this will be the last Frontier flight for me, regardless of the pricing."

Cons: "I felt taken advantage of by the surcharges."

Pros: "Cheap prices"
Cons: "Being stalled on the tarmac for over an hour arriving to Denver. People missing connecting flights. Plane arriving late leaving from Denver to Seattle. No complimentary beverages."

Pros: "speed on check in, age and competent attitude of stewards(esses), clean passenger area."

Pros: "See above."

Cons: "Charge for carry-on bags. Charge for seats. Nickel and dime website trying to upsell you on every screen. Seats don't recline, uncomfortable."

Pros: "Nothing."
Cons: "Everything."

Cons: "Trip had over 8 hours of delays."

Pros: "Cheap ticket"
Cons: "I felt nickle and dimes for everything"

Pros: "The price"
Cons: "The seats don't recline, the boarding passes didn't scan anywhere we tried to scan into."

Pros: "The announcement (although I didn't take them up on it) to offer two domestic round trips if I'd sign up for one of their Mastercards. It's probably not a bad deal for someone who likes to have lots of credit cards and doesn't mind annual fees, I'm just not one of those people."
Cons: "My inability to access their e-mail offers to set things up ahead of time and at lower costs than paying them at the airport check-in, above and beyond the baggage charges themselves (Seventy bucks), especially for my carry on ... COME ON! I've become used to Southwest's far more enlightened policies, which I obviously prefer. Since it also has flights between Seattle and Denver, I'll look much more closely at staying with them the next time I make this trip."

Pros: "Airbus jet was nice. Frontier credit card sign-up was offered."

Cons: "The fees for seat assignments and carry on luggage. Frontier also does not accept TSA Pre-check."

Pros: "speedy, safe, and friendly"
Cons: "no complimentary drink or snack. seats where uncomfortable"

Cons: "delays with NO feedback"

Cons: "They nickle and dime you to death. They even charge you for soda!"

Pros: "Nothing, never use them again EVER"
Cons: "NOTHING0 ZILCH"

Pros: "Letting me in though I got a bit late to the gate, due to unexpectedly log TSA lined"

Cons: "Paying for seat AND baggage is reason to fly Southwest."

Pros: "same as above"
Cons: "same as above"

Pros: "See cooment above"
Cons: "See comments above"

Cons: "I had to stay overnight in Denver, in the waiting area."

Cons: "My name was not correct on return email documents. When I tried to correct on-line, the program asked for another $139. When I phoned the number listed, I had a gentleman whose English was very hard to understand. He ended up telling me not to worry about the error-it would not cause a problem. I ended up phoning a 2nd time, to another person to assure that nothing would go wrong at boarding time."

Pros: ".It was a very confortable flight and right on time.."

Cons: "Finding that getting a seat costs extra"

Cons: "My mother did not get one of her bag back when we arrived in Seattle"
