Cons: "We had a delay of 3 hrs which kept us waiting in the middle of the night"
Pros: "There was actual room for my legs."
Cons: "There could have been more legroom so that you could actually get out without almost sitting in someone else's lap. But it was easier than my last flight (on American Airlines). Having a meal available would have been nice on a flight of almost 6 hours."
Pros: "Nice plane, good service and pilots, great landing - no issues at all."
Cons: "Flight attendant in First class was visibly frustrated and unfriendly. He was not helping with my simple request for a blanket. Also, the were no food service in first class."
Pros: "individual TVs"
Cons: "it would be great if you could not use all those one-use plastic cups. waste is a real issue in the US and the solution is using re-usable items like washable cups. Unboarding was a nightmare and it started to get really hot waiting to get off."
Cons: "Flight was 1,5 hr delayed, which almost caused me to miss my connecting flight"
Pros: "This was my daughter’s first solo travel home from college. She said the staff was helpful and kind. She loved that the flight was not over crowded. It was a smooth flight."
Cons: "Only negative thing she could say was her flight was delayed an hour. But that isn’t terrible considering all the holiday travelers."

Cons: "More organized boarding."
Cons: "Being sit at the plane for two hours and then having to deplane and board again plus further delays on the 44 minute fly to Boston made it feel eternal"
Cons: "Everyone was very rude and would not answer questions and flight very delayed. No bad weather conditions"
Cons: "They cancelled two of my flights in one weekend. We will not use American Airlines again."
Pros: "Was departed earlier because we were all on board early"
Pros: "The flight was early to arrive. There was also a rather frightening bit of turbulence, and the pilot explained why it had occurred, which I found very reassuring."
Cons: "The food was definitely below average. It's virtually all carbohydrates.Other airlines provide you with a printed description of the menu options, so it's easier to make a choice. "Chicken or pasta" doesn't give the passengers any idea of what they are actually choosing. This time the chicken dish was served with pearl couscous, so it was basically pasta as well. The salad I was given was brown and wilted, and while the cabin attendants were kind enough to give me two salad that were in better shape (after meal service), I just think that quality control should have prevented a inedible salad from being served in the first place. I am also extremely opposed to American Airlines Transatlantic luggage fees. Since I was moving abroad rather than taking a short trip, I was not pleased about paying 100 USD for a second bag on top of an already expensive flight."
Pros: "New gates at Philadelphia are beautiful but are hard to get in and out of and the design almost forces people into the hallway which clogs up pedestrian traffic down the corridor"
Cons: "There were no announcements at the gate. So it was very disorganized and people were frustrated I had purchased some fried breakfast rice at the gate and it came in a bag. The woman at the gat told me I had too many bags. It’s not a bag lady. It’s fried rice. She was not friendly. At least smile when you tell me to combine my takeout bag and my very small cross-body bag that is barely big enough to hold my Iphone. Most of the announcements in flight were muffled and hard to hear. The safety speech was really quite terrible. I think someone was torturing her to do it. It was really quite painful to listen to....."
Cons: "inflight entertainment wasn't working on my seat only which made my 6 hour flight seem even longer :("
Pros: "Great, friendly crew and excellent customer service from flight attendants."
Pros: "Seats were pretty comfortable"
Cons: "In-flight entertainment depended on the Wi-Fi working. It did not work the whole flight."
Pros: "The plane was nice and in good shape. They had beverage service for a very quick flight which is nice. Can't rate food or entertainment because only hour or so flight."
Cons: "It was freezing in the plane and I'm never cold. When I asked for a blanket they had none!!! They had just announced whatever they can do to make your flight more comfortable ask them. Not true, just words. Disappointed after the great treatment after flying ANA."
Pros: "Everything! The flight left on time and landed early. Service was great and the staff was super."
Cons: "Because of missed connection I had to go from Dulles to Reagan airport"
Pros: "Landing safely."
Cons: "Everything else. I flew from PHL to IAH and was very unhappy with the experience. The gate agents were unfriendly. The bag check agents downstairs were unfriendly. I had two separate phone calls with United a week prior to the flight to understand and confirm the bag policy. This was AFTER booking my flight so they knew upfront I bought a basic economy ticket. After my first call, I understood a personal item would be free and I would be able to pay for my carry on bag, but only within 24 hours prior to the flight. I made a second call to be absolutely sure the previous agent gave me the correct information and pricing. So I paid the $25 for my carry on, checked in online, and waited at the gate while boarding at the very end because I was basic economy. They did not let me board with my bag. They requested another $50 to check my carry on with them or I would be rebooked. I struggled to afford the flight, let alone the carry on fee I had paid in advance. I literally did not have the money, and even if I had the cash, they only accept plastic. What blew me away was they weren't asking me to check my carry on because of the size. But because of my basic economy ticket, aka, the N fare. Despite checking with two employees by phone after buying my ticket and paying for a carry on in advance, there is a rule in place that states "if you have purchased Basic Economy, you will only be allowed one personal item, unless you are a Premier member or a primary card member using a qualifying MileagePlus credit card." Therefore, there is no alternative. You are a second class citizen; a no good deplorable, when you buy this ticket and there is nothing you can do to upgrade it. Only the "premier" passengers have the right to bring a carry on aboard even if you think you're paying for the privelage. What I was expected to somehow understand after asking two United employees prior if I could purchase the right to bring a carry on bag aboard, was to CHECK my CARRY ON downstairs or learn the hard way. Wow. What a ruthless way to learn this lesson. I waited 7 more hours to board the next available flight. What a nightmare. I thought I had did the appropriate research necessary and planned in advance to avoid these situations. Checking in online and contacting customer service prior is no longer the convenience it used to be. Even if you've done your research, bring additional funds with you. Even if you check in online and have a digital boarding pass, always check in with a real human prior to entering the TSA security line. A side note, United is trying to save money while "speeding up" the process by forcing you to use a computer to hand over your checked luggage. Speaking with a human now is a monumental struggle."
Pros: "Clean aircraft, swift flight"
Cons: "Seat was changed to last row/middle seat (not what initially booked or confirmed with online check-in). Before takeoff, attendant moved all passengers in back row to alternate seats. Which meant that I was no longer traveling with my colleague. Unfortunately, that made our intended meeting time impossible."
Pros: "Free TV since we were 2 hours delayed"
Cons: "4 delays in 1 day on 2 flights. 2 gate changes with no relay of info and to top it all off my wife and i were reassigned to separate seats at the last minute by the airline and very rudely told to deal with it and to calm down when I simply asked why. We were appalled and embarrassed in front of many others in the gate boarding area. The gate agent in Houston has no place in customer service and was on some kind of a power trip. This surprised me with recent events. We are done with United now for many reasons"
Cons: "The fact that I have to pay extra for food or any form of entertainment is appalling compared to other airlines. $20 for WIFI? That's a joke."
Pros: "One of the friendliest and most customer friendly flights I've had in a long time."
Pros: "Extra legroom where definitely worth it!! Crew was pleasant and professional."
Cons: "Waiting area in Phillie airport needed some live. That may not be Frontier’s responsibility..."
Pros: "Captain was informative but not too talkative. Left on time and arrived 20 min early"
Cons: "It was a 6 pm take off and the only food available for purchase was a “snack pack”. A tiny piece of beef jerky with crackers, cheese, and 10 Chocolate covered blueberries for $6.00. Made the mistake of not eating before and was silly to be expecting more from a discount airline I guess."
Pros: "Seats where comfortable and I had space"
Cons: "Maybe TV's can be added, the crew members weren't so hospitable"
Pros: "Crew was amazing, I love that they had tablets to take the order instead of driving the cart up and down the aisle."
Cons: "Paid fifty dollars for more leg room and it basically felt like basic seats that I’ve flown with such as spirit and American Airlines"
Pros: "Flight on time, crew was friendly and helpful. Boarding was seamless and overall great experience for the price"
Cons: "Not much leg room but expected with budget airlines"
Pros: "Was direct and easy. No issues with boarding or flight"
Cons: "Cramped"
Pros: "The crew more than adequate. Very nice."
Cons: "The two hour delay caused by no one noticing that the tires needed to be changed which, according to your own pilot was listed as part of the needed ground Maintenance. Boarding the plane before they were changed. De-boarding the plane to change the tires. The one and a half hour wait at the gate for your company to approve the plane for flight. This was not a good experience and I do not want to fly frontier again as a result."
Pros: "Nothing"
Cons: "I will never fly Frontier airlines again. No matter how inexpensive the tickets are, it is not worth the aggravation. Agents were rude. Flight horribly delayed. Plan ride was uncomfortable. I lost my car rental because they close at 5:30pm. When there own employees say there flights are always delayed that alone said it all."
Pros: "I arrived safely. The crew was very friendly and helped to. All my husband who was scared as this was his first time flying."
Cons: "The agent who checked me in was extremely unprofessional. I felt like she was envious that I was going on a vacation and she had to work. She tried to make my experience a living hell. I personally think she should be fired. She does not enjoy what she is doing. She joyfully told me that it costs $40 to carry my luggage and after I informed her that I saw it online for less she informed me that I should have bought it online. She then stuck me all the way in the last row of the plane. I am 5'9". My husband is 6'2" and over 300 pounds. Those seats have the least leg room. It was pure torture. The flight crew in the back help my poor husband by using humor to help him."
Pros: "Although the flight was delayed half an hour....I was happy with the service and crew."
Cons: "A free juice woulve been nice....but oh one's gonna die of thirst in 2 hours."
