Upon arrival, bag was left in NYC but this wasn't communicated. No info on bag status at airport or via ema"

Cons: "It was late"

Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"

Cons: "I usually don't fly from JFK. The food court was expensive (18 dollars base price from a burger seems a high even for an airport. I don't fly from NY normally - so maybe I need to tune my expectation for the locale, and it may have NOTHING to do with the airline company."

Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."

Pros: "There was a bit of a mixup in boarding the plane but otherwise the flight was good. There was no entertainment system on this short flight. The flight attendants were very pleasant & efficient. They only served snacks on this short flight but were very good at ensuring everyone had at least one or more beverages. The premium seats were very comfortable ."

Cons: "The aircraft is too old, MD-88. I don't know how Delta is flying that type of aircraft. Is very risky"

Pros: "It was a smooth boarding, flight and exit out of the plane."

Cons: "Flight cancelled due to weather that was never bad but on the potential of bad weather. Had to scramble so my 18 year old son was not stranded overnight in a strange place and Delta does not help. Only rebooked a flight itinerary for the next day for a 4 hour flight with connections on a 1 hour direct flight. Spent an hour on line to figure out what to do. #neverdelta"

The arm was not able to go down comfortably, and when it did it was not usable . The passenger on my left, window seat, was probably 6'7" and had to sit with a man spread in order to fit. I could not move and was extremely uncomfortable. The plane was overbooked so I was unable to move. Therefore, worst flight ever. Plus, I paid for a full seat and was only able to occupy half of it."

Pros: "The crew was polite and friendly"
Cons: "My second plane had sooo much moisture coming from the cooling system it looked like the passengers were getting gased and I kept getting wet from water condensation falling on me in a window seat as I tried to sleep from having such an early flight to begin with only to be told it's delayed 3 hrs without explanation."

Cons: "The ONLY thing negative that I can say is that the Chicago airport had no charging stations at my gate."

Pros: "Once the flights took off, everything was just great."
Cons: "The boarding process was awful. There are zones, but they are all boarded simultaneously. What's the point of paying to board early if you don't get the chance. Then, I had to check my bag because the boarding order was a mess. One flight attendant tried to force me to put my bag overhead when I told her I could fit it under the seat. She stressed me out unnecessarily."

Pros: "For the basic economy seat there was plenty of room and the staff was excellent. Honestly the best domestic flight I've taken in a long time."

Pros: "The gate at the Chicago airport was well designed. There was a line for each boarding group, and you could line up early. This is particularly effective for some Asian flights, which can sometimes be chaotic with many different nationalities all lining up."

Pros: "Service"
Cons: "Total disaster due to some snow, excessive delays"

Pros: "temperature was right not blanket needed"

Cons: "Lack of leg room, no TVs, no free wifi"

Cons: "Flight was delayed because one of the flight attendance was late showing up."

Pros: "Flight was on-time."
Cons: "Flight to Washington Dulles was boarding at the same time through the same door as flight to Washington National. Why would you schedule it this way? Plane cabin lighting was mostly burned out so very difficult to see while getting on the plane. Window appeared to be caulked on, exit door handle cover in row behind was falling off causing concern for passenger in exit row. Plane was generally shabby and run down. Flight attendant was reading all announcements which did not inspire confidence in her training. Small regional jet, so seats and leg room were terrible. Made us wait outside in the cold for our hand luggage that was too large for tiny overhead bins while we watched baggage handlers drop several carry-ons from the conveyor belt onto the ground. In addition they lost one of our two bags."

Cons: "The flight was over one hour late departing ORD. We had approximately 15 minutes to make our connection at IAD. While I understand that the delay happened because the copilot was late because of a fender bender, I believe the delay could have been much shorter. Since they had telephone contact with the crew member we could have been boarded before he was on the plane and departed sooner. Also no reasonable explanation was given for the delay other than a crew member was not there."

Cons: "Flight took off early while I was still aboard the inbound connector. I was supposed to be mollified with a boarding pass for 9 hours later and a hotel room. Gee thanks."

Pros: "Kudos to staff during difficult weather"
Cons: "Late notice for cancellation"

Pros: "Was never in Chicago."
Cons: "Was never in Chicago but my stuff was."

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Pros: "Good crew"
Cons: "Bumpy air"

Pros: "The appointment as shape"
Cons: "Small aircraft and noisily to much"

Cons: "The wait for my carry on baggage..."

Pros: "Nice"

Pros: "I liked the fact that I can fly red eye."
Cons: "I typically fly Southwest because of the free leg room, free 2 bags checked, and 2 free carry-ons. Frontier "fee's" flyers to death. I have to pay extea for leg room????!!! REALLY! I could see if i was 6'6" but I'm not. If Southwest ever offers red eye flights I'll never patronize Frontier or another airline again."

Cons: "not clean"

Pros: "Bag charged"

Cons: "Short-staffed, so short tempered workers.kiosks did not work. Nickled and dimed on everything. Like flying in prison. No light and a cold hard bench seat. Awful."

Pros: "Very efficient."
Cons: "No free beverage."

Pros: "This was the first time I have flown Frontier. Even with a checked bag fee ($30 each way), my total fare was still less than half of what it would have been for competitors the same week. The planes were clean, flights were on time, and the crew were extremely friendly and helpful!"

Pros: "I was upgraded for free!"
Cons: "The payment necessary for baggage."

Pros: "The whole trip is pretty bad. It is delayed for 5 hours. And no free water on the airplane. You basically has to pay for everything: food, checking luggage, and carryon bags. No entertainment at all. The flight tickets are not cheaper anyway."

Pros: "There wasn't any in flight entertainment and I didn't order food, so that's why my rating is neutral. Our flight back was 30 min early, so that was great."

Cons: "Everything!!"

Pros: "Aircraft"
Cons: "Nothing"

Cons: "Not very informational on security policy"

Pros: "Snacks & drinks included."
Cons: "The cost of baggage but on the other hand the airline fare was so inexpensive that in reality the trade off was worth it. You must a strategic packer when flying Frontier."

Pros: "Everything was good, no complaints"

Pros: "Staff"

Cons: "The Chicago airport was terrible both times. Things not clearly marked. Staff not friendly or available. Long term parking very hard to find and pricing very unclear. Didn't realize we would have to pay additional for just a seat and carry on luggage"
