Pros: "Crew was very friendly and took good care of the passengers"
Cons: "Crew was abrasive and put off by people asking for service. Monitors had to be rebooted 3 times. Ran out of water and snacks."
Cons: "Made us check our carry ons and there was plenty of space in the cabin overhead comoartments"
Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Pros: "The crew was communicative and courteous."
Cons: "There was a flight delay in LAX due to a maintenance issue. The captain and crew informed us before we boarded the plane which was excellent. However, they could not figure out what was wrong with the planed and delayed the boarding for another 3 hours, putting our 1900 departure time to 2100."
Cons: "Do not lie to the passengers and make a lot of people check their bags when it’s empty overhead bins."
Pros: "The crew and staff were friendly. The flight was full so they checked our bag at no additional charge."
Cons: "They had no earphones for the flight from Cancun."
Pros: "Nothing"
Cons: "I came from a long trip from France, the seat I was assigned was not reclinable, close to the restroom. I was totally exhausted from the previous flight, not able to sleep at all and when I tried to stretch my legs by sitting sidewards on the aisle a crew member keep bothering me to keep my legs out"
Pros: "Yes"
Cons: "Took off late. Other than that very comfortable and great experience"
Cons: "My kids were asleep when the flight attendant passed the snacks . I asked to get the snack for them and she told me they will have to get it in the back of plane once awake. Didn’t argue but was surprised"
Pros: "I paid more money to take the 14:40 flight rather the 15:15 which was $100.00 USD less, to find out my flight was delayed by 45min.. seat didn’t recline and was just a bad experience"
Pros: "One of the flights at least had onboard movies."
Cons: "Better organization, And no discrimination from the airport staff at Mexico City. Including the lack of information given (sign showing on time) when clearly there was a 3 hour delay and the gate number kept changing and none of the staff knew what was going on"
Pros: "The crew was just ok, they did not extend themselves to make the customer feel comfortable/safe."
Cons: "The seat on the flight are too small the average person does not fit comfortable."
Cons: "Not being able to choose an aisle seat made the flight uncomfortable for me and my neighbors"
Cons: "The flight was delayed by three hours (reason unknown) and the entertainment on flight shut off once and then froze for 20 minutes"
Cons: "Boarding process. The Zone lines are formed a very long time before boarding really begins. Why?"
Cons: "Check in was very slow with long long long lines."
Pros: "The meals and flights attendance were great"
Cons: "The AC on flight 748 for some reason it wasn't cold enough. No entertainment on the seat. Maybe is older air plane."
Pros: "We boarded fast and we arrived on time"
Cons: "I requested a "Fragile" label for my suitcase. They said they ran out of them. When I came back home, they had break 2 memories. One of them from the conference I taught. I tried to wrap them as tight as possible. I am aware of the risks of carrying fragile things but I can't stop thinking that the label might had helped avoiding things getting break. Flight Attendance were not very friendly. They were not rude but defiantly not friendly"
Pros: "we upgraded to emergency row for free which gave us a lot of extra legroom. The flight attendants were always available. Basic drinks were complementary."
Cons: "We were early arriving on both legs of our flight, which was nice. Charlotte Airport staff was rude as usual, so nothing new there. Overall, we had a great trip."
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "That I had no issues. Timely, staff accommodating, area cleaned."
Cons: "Had no concerns..."
Pros: "On time departure. Early arrival. Lots of seat back movies."
Cons: "Need more new releases for movie selection."
Pros: "Nothing. Just the pilot"
Cons: "Everything. Bad communication. 1 h delay. Then 3 hs in the plane. We ran out of gas. 2 more hours taxiing Never seen something similar. I really hope my mileage refund."
Pros: "Awesome roomy seat right behind business class. Could not have asked for better! And it was a gorgeous new aircraft."
Pros: "I love your entertainment selection. also the comfort of seat and it's on time."
Pros: "Nice new seats."
Cons: "The new seats are meant for "people shorter than 6 feet tall" as the flight attendant said to me. Is the airline industry deliberately discriminating against 6'6" people? 15% of the people you seat based on population are over 6'. I'm sick of paying more money for my long legs."
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."
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."
Cons: "Seats stuffed like sardines 5:10 and my knees were touching the front seat. My seat was Brocken and did not recline . Stuck like this for 6 hours .....-;( I did not even know you are allowed to put seats so close together"
Pros: "Seats were very comfortable in first class. Very happy with that experience for short haul flight. Enjoyed the service. Flight attendant checked on me multiple times and offered beverages."
Cons: "Snack/food choices."
Pros: "Safety of the flight, the route"
Cons: "The remote for the AV was so torn. I coukdnt even use it"
Pros: "Safe flight. Also, I was offered a different flight from Boise, ID, in order to make my connection in San Francisco. Thank you!"
Cons: "NA"
Pros: "No entertainment. Not working No internet. Crewfelt like they were forced to be “nice”."
Pros: "the entertainment program was good, and the plane in good shape"
Cons: "food was terrible"
Pros: "Boarded, departed, and arrived on-time."
Cons: "The movie selection was a bit thin and wasn't updated from the previous month's selection."
Pros: "United terminal in San Fransisco is pretty nice."
Cons: "The service by flight attendants is horrible. They are not even pleasant to talk to. They are not helpful. My audio jack was not working and the flight attendant just replied. Nothing I can do. She didn't offer any solutions. The airplanes are like buses with amenities, no leg room even in the economy plus. Just a horrible experience, overall. I have flown multiple airlines but the United is by far the worst airline in terms of service, customer support and airplane quality."
Pros: "Was told there was a delay of 15-30 mins at check in. Flight was actually delayed 1.5 hrs. Would have been nice if they explained why ahead of time."
Cons: "More food options. Almost wasn't able to buy food. Was told they ran out by the time they reached us in the back of the plane. Luckily they had one left. It was luke warm at best and my husband and I split it."
Pros: "I enjoyed my interaction with the other passengers."
Cons: "Several delays compounded to make trip a lot longer and far less comfortable than it needed to be."
Pros: "The crew was very attentive to each guest."
Cons: "Well I paid more for a lesser quality plane ride... didn’t like that very much."
Pros: "The Crew"
Cons: "It was a passenger on the plane acting real suspicious. I didn’t like that. Also the seats was uncomfortable."
Cons: "The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future."
Cons: "if flight was delayed should at least provide complementary soft drinks..."
Cons: "There was a malfunction online and I was overcharged for my flight. There were also delays going to and from my destination."
Pros: "Larger seating was available."
Cons: "Additional charge for carry on luggage. No entertainment and no "free" food. The adds on (seat/luggage/food) put the cost of flying with Frontier to the same level as the airlines that don't charge for additional "things"! So why wld you fly "discount " if in the end you pay as much...possibly more than the competition!"
Cons: "I dont even know why you are sending me a survey of a flight i didnt even have... Plus, you didnt send me an email to let me know that the flight was canceled, i realizado that once i got to the airport... you should do something about it"
Pros: "The crew was friendly and helpful."
Cons: "There were extra fees for carry on and checked bags, which was not revealed until we printed our boarding passes. In addition, we had to pay to reserve seats. On top of that, I have never sat in such uncomfortable seats. They charged $2.99 for a can of soda on the flight. Finally, they lost our bag, after our flight took an hour longer than it was supposed to."
Cons: "The flight was first cancelled, then I had to wait two days for the next available flight out. Also was charged for my carry on bag. This airline does not offer any complimentary drinks. I will not book this company again, you think your saving a little and end up spending More at the end."
Pros: "We didn't crash."
Cons: "Frontier has to be the worst airline I've ever flown on. You have to pay for everything "extra". Your ticket doesn't even give you a seat, you have to buy your seat extra, carry on is extra... Etc. might as well charge for using their tray tables while they are at it. I can honestly say I'll never fly with them again."
