Cons: "Was nervous regarding the announcement they made before the flight. Everyone was to stay in their assigned seat due to the lack of people on the flight. They needed to balance off the plane. We were afraid to get up and walk around. Wasn't happy about being placed in the back of the plane because it was so LOUD."

Cons: "By this time in my trip, my day had been so long, and I was still so upset over how late we were due to some selfish individuals and an airline catering to them, that I was not capable of assessing the flight.

Another reason I doubt I will ever use Icelandair again."

Pros: "Loved the early arrival, the seamless process."

Pros: "Sat in Premium. Early board because of wheel chair. Lots of room. Smooth flight. Arrived early in Seattle. Ta very nice. Took all way to car in parking lot. Cleanliness."
Cons: "TA forgot one of my bags at security..but I didn't miss until almost to departure gate. Had to check my medicine bottle of cough syrup. What a pain. Put into separate basket. Open & swab.

Pros: "Not much crew stayed in back almost the whole 6 1/2 hr flight and seemed not to friendly"
Cons: "It would have been better if they had departed when they said they were going to after a delay. Flight was delayed first 1 hr then two more hours. The airline finally posted that it would depart a 4 PM and we didn't even start boarding until 5PM. Then they tried to rush us on so that everyone was standing on the HOT jetway for 10 min waiting to get on the plane. Plane didn't take off til 5:35 PM. Over all on this trip I had three flights that were delayed. I'll think twice before taking American Air again."

Pros: "I slept the whole way!"

Cons: "Todo"

Pros: "The crew was pleasant."
Cons: "My wait for a wheelchair was not good at all I was assigned for one but someone else that had declined there took mines and I had to wait. As I arrived to Phoenix. I was not impressed with that"

Pros: "Nothing was overlooked. My beverage was always full and the kind gentleman who cared for the 1st class kept walking around to check all our needs. Excellent service!!!"
Cons: "Attention to details. Food was also delicious. Fillet mignon with lobster Mac and cheese. Yummy for my tummy, indeed!!!"

Pros: "Fast boarding in good order"

Pros: "Staff always amazing."
Cons: "Everything was good overall."

Pros: "Nice new interior"

Cons: "Immediately after all passengers were boarded United discovered the plane had to be replaced. We all had to deplane, wait an hour more for a new A320, and reboard. Also irritating that delays are posted at 15 minute intervals and then updated; so you have to keep updating friends & family via WiFi. If it's predicted to be an hour, say so."

Cons: "our flight was delayed in Chicago and our bags were not in Phoenix upon arrival"

Pros: "Nothing"
Cons: "My email is not linked to my phone, so I got no warning notices of two gate changes waiting for my connecting flight home. I waited at the original gate (C39) from arrival time (2:30 pm) til boarding time (5:40 pm). When I saw no change to my destination, I checked the United App to find that the gate had been changed C33). Rushing to C33 I found another flight boarding at that location with one United Representative who could not stop to answer questions. Seeing two unoccupied Representatives at the next gate (C32), I asked if they could help me with the confusion, they said I should check with gate C33 - which I told them that she was too busy with other passengers. I searched for a Departure Board and discovered that gate C33 was still the gate, but "aircraft maintenance" had delayed the flight until after 8:20. After having to check my carry-on because of lack of space in the overheads, my departure from the airport was further delayed another 30 minutes. Upon returning home and checking my email, I found notifications of two different gate changes (C33 & C44). Announcements should have been made at both gate C39 about the changing of the gate and at C33 explaining the problem. The captain's lame excuse about air conditioning and Phoenix's hot weather was lame to say the least."

Cons: "No room for my knees - they hurt considerably afterward. The seat did not recline."

Pros: "Nothing"
Cons: "Bad experience"

Pros: "CorteousAll"
Cons: "All was good"

Cons: "Not enough legroom"

Pros: "Again expectation can get in the way. And of course the airline needs for flights to be as full as possible. In order to be profitable in the long run. We all want them to be able to stay in business"
Cons: "Same point - the point was full and I’ve already clarified that ."

Cons: "There was no entertainment available on this flight. It's a short flight so I don't expect any, however, I continued on to Phoenix that day from Chicago and that is a long flight. I expected free entertainment on that flight, as it was afforded on the flight on the Phoenix to Chicago leg of my flights earlier in the week. The Chicago to Phoenix had entertainment offered but it there was a fee, which I didn't appreciate and did not take part in. I looked around me as much as possible and didn't see anyone else pay for entertainment. Having in flight movies and TV available for feee is a great incentive for flying with United. If these long flights in the future are pay for view, I will not be flying with you when there are alternative carriers who do provide free entertainment. Thank you."

Cons: "Too tight for legs."

Pros: "Ontario airport is so easy and convenient"

Pros: "Easy, convenient and everyone is nice and accommodating. We always get to SFO under an hour"

Pros: "Covert belt to load the bags were not working hence 3 Hours delay which messed up all my plans."
Cons: "My whole plan for the with family was Affected."

Pros: "Nothing"
Cons: "Purchased ticket and it was this thing called Basic Fare Ticket???? Which means No refund, No Cancellation or Rescheduled Flights! You cannot pick your seat and will not be able to purchase a better seat even if it says available. Paid way too much and had to stay longer for my father's heart attack and lost the ticket and had to but a 1 way ticket back home and had to purchase my seat on top of all this. Over $1600 paid and still wanted $80 for my seat of choice. How Greedy."

Pros: "Same"
Cons: "Same"

Pros: "on time"

Pros: "Small plane. Smooth. Loved it"
Cons: "space tight"

Pros: "No issue and on time"

Pros: "Que acomoden a las parejas juntas."
Cons: "Asiento incomodo"

Pros: "On time"
Cons: "Boarding takes too long"

Pros: "Everything was pleasant."

Pros: "Good service good snacks."

Pros: "Nothing."
Cons: "Staff."

Pros: "2.5 HR layover lost bag"

Pros: "Personable staff, great flight time and an awesome landing."
Cons: "Boarding groups 3-5 lumped together into one Line."

Pros: "On time , smooth flying, great service"

Pros: "Fast service!"

Pros: "Comfort alerts to delays"
Cons: "Hate hate hate having to check carry on at the gate There is pkenty of room if enforce the carry on under the seat Do so It is unfair to make later groups pay for selfidhness"

Pros: "Great staff."
Cons: "A crying baby that say behind me."

Pros: "I felt comfortable. Staff was great."
Cons: "The cracker and cheese box. The snack wasn't worth the money."

Pros: "Everything was fine."

Pros: "United got me from point A to point B"
Cons: "Crew was rude, not just to me, but to other patrons. Flight was packed going and the man scanning boarding passes spoke to those of us asking simple questions as if we were stupid and defiant. Was he a prison guard in his previous job? On the way to Newark, I had an aisle seat. One of the stewardesses blazed by me with a cart ramming it into my shoulder without so much as a, "sorry." I'm not a big woman but maybe as I dozed off I leaned over a bit...There is no way she didn't feel her cart hit me. Rudeness, it seems is a part of the culture at United because the flight attendants coming back squeezed past the long line for the bathroom without saying, "excuse me." They did however, say, "I need to get by," and one of them brushed by the gentlemen sitting next to me and bumped his laptop and coffee. Overall it seems that the crew working these particular United flights have forgotten that we pay hard earned money to fly. Some of us are going on vacation, to see loved ones, and some are flying to deal with unpleasant circumstances. The staff may fly several times a day, but most passengers do not. There's a lot of prep and anxiety, that goes into taking a flight and a surly flight crew multiplies that anxiety. No one wants to fly with a crew that hates their job."

Cons: "They overbooked my flight and almost didn't let me on the plane even though I bought my ticket months ago! The only reason I got on is because some people didn't show up."

Cons: "It was delayed 3hrs!"

Cons: "It was a new plane but it was extremely uncomfortable. The chairs were so stiff."

Cons: "The delay and lack of communication to customers."

Pros: "It was on time And very convenient"

Pros: "On time."

Pros: "Nothing"
Cons: "Everything. United made no apologies."

Pros: "It was ok."
Cons: "Small.plane, nasty sweet snack! Geez are peanuts that much more expensive!?"

Pros: "Staff excellent"
Cons: "Everything else, space restrictive"

Pros: "I liked the boarding process. The staff were nice people too."
Cons: "The plane made a horribly alarming screeching sound before takeoff. WiFi was out. The snacks tasted like stale trail mix from a Fresno gas station."

Pros: "Nothing out of the common."
Cons: "WiFi never worked. And again... Uncomfortable."

Cons: "They crushed my luggage but replaced the carry on after."

Pros: "Good service"

Pros: "That's it was fast and organized"

Pros: "The crew they were awesome"
Cons: "All was good"

Pros: "Non stop"
Cons: "Seats suck"

Pros: "The attendance"
Cons: "Tight seats"

Pros: "That I made it there in one piece."
Cons: "Not worth saving a couple dollars. Front tier airlines does not allow you to pick your seats before hand nor does it allow you to select baggage and the app, it is recessed for whatever reason. The seats are extremely tiny the tree table is so small you can barely fit an English muffin on it. There is no entertainment whatsoever, there is no Internet on the plane, and if you want anything to eat or drink besides water you will be paying for it. I’m sorry to say but flying on frontier was more like a punishment for me. I always fly American and wanted to save a few dollars what a mistake! With American most the planes that I have flown in have free movie entertainment and everybody seat the seats are comfortable And recline. And the snacks are free along with the soda. Please think twice before flying frontier."

Pros: "Nothing"
Cons: "Late. Late.Late Staff seemed rude"

Pros: "Do people write here for frontier?"
Cons: "Sat on the tarmac for over 3 hours. A fight broke loose and we had to return to the terminal and then back to the tarmac for more sitting. The crew finally figured out how uncomfortable and frustrated people were getting 2.5 hours to sitting with no air on the tarmac. They relieved their customers suffering then with complimentary water! Now that’s service. Frontier is one of the most base airlines out there. I’m entirely frustrated that they are one of the only airlines that service our podunk airport."

Cons: "more room between seats-"

Pros: "Nothing"
Cons: "Everything. The staff kept lying about the fueling issue. They kept blaming the fuel tankers being frozen. They said 3 of them came, however i sat on the window seat and only one tanker came. After being delayed for 2 hrs and 15 minutes, when we got to cruise altitude they asked us for money for water. Are you serious? Also i was told that same plane will depart from Denver to Phoenix. I was told the same thing while in Chicago, during the flight to Denver and in Denver. It turns out everyone knew the flight left already from Denver to Phoenix. Needless to say, I won’t be flying with frontier ever again."

Pros: "The flight attendants were very nice and comforting, as this was my first time ever flying and I was terrified."
Cons: "The boarding staff were rude! There was absolutely no form of entertainment. The seats were uncomfortable online said they recline for comfort however I couldn't find anywhere to get them to recline."

Pros: "Low fares done right?? Until they try to charge you $45 for a carry on. Frontier will end up costing you more in the end."

Pros: "price"
Cons: "Seats are uncomfortable"

Pros: "Boarding was timely"
Cons: "Extra fees for everything"

Pros: "Same"
Cons: "Same"

Pros: "The cost of the flight"
Cons: "No complimentary beverages or snacks"

Pros: "I got to phoenix safe."
Cons: "The lady next to me. She was snoring."

Cons: "Called in to book and the agent booked my trip backwards. They would not reimburse full unless I rebooked that moment so they only did half which I have to use in 90 days"

Pros: "Pleasant & helpful service."
Cons: "Crowded seating."

Cons: "Flight delayed To much extra charges (seat, carry on, etc)"

Pros: "Good fare prices for tickets."
Cons: "Seats don't recline."

Pros: "Great take off and landing. Very comfortable seats."
Cons: "That no snacks or beverages were provided for free"

Pros: "I enjoyed the trip in though your people are slow."
Cons: "The seats"

Cons: "Lost luggage"

Pros: "Attendants at the boarding site in Phoenix are great!"

Pros: "It was cheap!"
Cons: "It was cheap. You get what you pay for... I had forgot that there were absolutely NO additional frills with this airline... You get one cup of water and absolutely nothing else. The staff was a nice as can be expected, but didn't look like anyone wanted to be there. And when my husband asked for some hot tea (thinking it would be complimentary - it was not), they got very frustrated. But I would guess they're just victims of their circumstances, so no hard feelings... Still, wouldn't recommend unless you're on an extreme budget."

Pros: "Likely the most uncomfortable plane I've ever been on. Seats feature zero padding, the inability to recline, and a tray table the size of a DVD case. I'm 5' 9" 148 pounds, young and very healthy. I left the plane with a twisted up neck like I've never had before. I landed safely so I MUST be thankful for that, but if I was booking I would want to know this information. Since I'm the wiser now I will not book with Frontier again. Also it was an extra $90 for my CARRY ON round trip. It notified me it would be extra when I booked online but didn't specify how much. What a surprise. I spent more on the fees for the bag than I spent on the bag itself (and most of the contents for that matter)."

Pros: "Everything"
Cons: "Nothing"

Pros: "No wifi made the trip unbearable."

Pros: "nothing."
Cons: "all of it."

Cons: "Seats"

Pros: "The crew was very rude, and ignorant, the only thing I did like was that the pilot let us know what was going on"
Cons: "I was the last one on the plane, because I did not check my carry on bag before hand, I was charged 60 dollars. After the fact, I was waiting to get to my seat behind a mom, and her approximately 6 year old son. As I am waiting to find my seat an attendant says to mean, "sir can you please find your seat, we can not back away until you sit down." At this point I am thinking what in the neck do you think it is I am trying to do, but I keep my mouth shut. Then, of course, I have a window seat. So I ask the people in my row to kindly allow me to get into my seat. While an elderly woman is in the process of moving so I can get to my seat, the same attendant says to me in a very demeaning tone "sir please find a seat." Again, I keep my mouth shut, but I am about to lose it on this guy. I finally am moving into my seat, and the attendant announcing over the speaker says, "we can play musical chairs later." I am just disgusted with the way these situations were carried out by the frontier staff. First I pretty much get 60 dollars stolen from me, then I get yelled at and made fun of because I was being kind, and not bashing through people to get to my seat. Not a very pleasant situation, I will never fly frontier again, spirit staff is way nicer, and the prices are cheaper too."

Pros: "Noting"
Cons: "Everything"

Pros: "NOTHING"
Cons: "Was late going and coming back"

Pros: "Finally getting home"
Cons: "Employees were helpful"

Pros: "I arrived 40 min earlier. Great job"

Pros: "Fly delay 3 hrs. Waiting 4 pilot . they make us wait inside plain no air conditiloner. Super hot"
Cons: "Nothing"

Cons: "No room, very uncomfortable"

Cons: "Exorbitant bag fees and crappy airplane."

Cons: "My bag was 6 lbs the weight limit, so I had to pay $115 for one checked bag and $40 for a carry on. Not sure if it is on PHX or Frontier, but waited 25 minutes for any luggage to show up to the carousel."

Pros: "Nothing"
Cons: "Ground crew was not ready… 20 minute wait. Couldn't attach jetway… 25 minute wait. Baggage was delayed 45 minutes."

Pros: "There was great deals on snacks and beverages"
Cons: "My plane was 2 hours late, but they didn't properly note the delay and my grandparents were looking for me for an hour all over the airport."

Cons: "Flight delayed"

Pros: "Price"
Cons: "Seats, no drink/snack, too hot upon boarding (no AC).."

Pros: "The airline niceled and dimes you to death. My luggage charges were almost as much as the airfare. I will never ever fly Frontier again. The trip sucked!"
Cons: "NOTHING"

Cons: "NO BAGGAGE & VERY LATE AT NIGHT"

Cons: "Delayed flight. Everything took longer than expected"

Cons: "Charging for carry on bags - charging for drinks -"

Pros: "Quick boarding! ! Love getting on fast and flying out."
Cons: "Paying for a soda is crazy! Increase everyone's ticket by $1 and offer cover, tea or soda. It would still make you money with less paperwork."

Pros: "It got me to PDX. That's a good thing."
Cons: "No intertainment, you had to buy anything you wanted. NO freebies."
