Airline reviews
Cons: "The seats were very hard and uncomfortable for a 5 1/2 hr flight"
Read more about JetBlue
Cons: "The seats were very hard and uncomfortable for a 5 1/2 hr flight"
Cons: "Long delay and communication problem, delay was moved up. Impossible to plan."
Cons: "Too hot. They need to turn off the blue light for a red eye..."
Pros: "Flight was comfortable and entertainment was appreciated"
Cons: "Flight attendants weren’t all there... somewhat rude. Flight attendant gave the wrong local time (you even heard her count through the speaker). Same flight attendant abruptly woke up passengers bye saying “Wakey, Wakey” in the early hours of the morning (we were traveling from NY)"
Pros: "The crew was unfailing cheerful and helpful. The seats are comfortable and there’s a little more space than some airlines. The fight and particularly the landing was very smooth. Great experience!"
Cons: "That the flight kept on getting delayed. JB staff should be more efficient. We understand the delay of up to one hour, but no one had any idea what was taking so long. we are two senior citizen with medical conditions. We specifically choose to fly JetBlue because they are on time and because of their service. We paid more to go with JetBlue, we could have gone with another cheaper airline. I guess it is time we change the way we think"
Pros: "i loved that they had television, free wifi, snacks and drinks. there was also a lot of leg room."
Pros: "Boarding went well"
Cons: "I asked 4 times to 3 different attendants to please reset the TVs so that the rite could be fixed. I was not the only passenger in the row and we both were going to enjoy the entertainment that we purchased with our flight tickets. Not only that, but tHe flight attendant knowingly allowed someone to try and enter the bathroom right after watching me go in to use it. I was completely shocked that they were so caught up in their personal conversation and could not bother to warn the person that i was using the bathroom"
Cons: "I had a late evening flight and my neighbors chatted very loudly the entire flight. The gentleman’s seat was one row ahead but decided since there was an empty seat in our row he would sit with his girlfriend. The couple smelled of alcohol, not sure if they were served with more than one alcoholic beverage but it made the flight very uncomfortable. Even with my earphones on at a higher level I could still hear them."
Pros: "Everything except the video service was great."
Cons: "The video in front of me no only didn't work, but kept randomly flashing the whole flight, so it was annoying even with eyes closed. Everything else was great.."
Pros: "Delta has the best flight crew! Couldn’t ask for a better airline!"
Cons: "Provide blanket and pillow in first"
Pros: "We like how delta still has the middle seat open. Makes it feel more comfortable. Also the loading the back of the plane first. Always was a smart idea, glad it’s finally happening."
Pros: "Crew was solid."
Cons: "Don’t change my seat. Not on time. No food. Luggage with legally checked firearm sent to the wrong airport."
Cons: "Needed assistance for limited mobility to make connections at ATL was not provided. Caused us to miss connections and had two falls trying to get around. Air France was terrible. Very limited food and beverage service left us hungry and thirsty on 7 to 10 hour flights."
Pros: "Crew is amazing, seats are pretty good."
Cons: "On time, baggages checked in and were made available on time."
Cons: "The in-flight entertainment in my seat did not work properly so I could not enjoy watching movies or shows. A minor but unfortunate inconvenience."
Pros: "Nothing"
Cons: "Better customer service. Your employees should be te-trained and reminded they are in a service industry where your clients have other options to fly."
Pros: "Inflight entertainment was great. Movies, games, moving map. Best I’ve ever seen in main cabin for free."
Cons: "The seating was too cramped. It’s extremely uncomfortable. Seems tighter both on knees and elbows."
Pros: "Crew was excellent. Friendly and always with a smile."
Cons: "The headphones distort the sound too much. You miss half the dialogue if you are using the Delta headphones."
Pros: "Pilot and his ability to maneuver the turbulence. Also variety of snacks."
Cons: "Felt hot in the plane."

It was fine. I didn't love the food but it was at least a real attempt at serving a meal, unlike my earlier flight from Nashville to Dallas.

Pros: "Seats were comfortable didn’t have to pay extra for my personal day crew was polite"
Pros: "I was arriving only 45 minutes prior to departure time. Not able to check in my luggage. AA ticketing agent allowed me to bring my garment bag through security and to be checked in at the gate. Thank you very much!"
Cons: "Nothing really. Very satisfied customer here."
Pros: "Plane was newer than I expected. Had tv monitors on the back of seat headrests."
Cons: "The flight was delayed an hour because the flight crew was late."
Pros: "The boarding process was easy. Crew was friendly. In flight movie selection was great."
Cons: "Seats were uncomfortable and some passengers could have used a little deodorant."
Pros: "Made it to my destination"
Cons: "2-hour delay in the plan after departure from the gate for maintenance. The seats are so small that my knees hit the seat in front of me the entire flight."
Pros: "More space in these seats than in other flights I’ve taken"
Pros: "Food was so so on board BA flight"
Cons: "Personel of BA in general very arrogant and think they rule"
Pros: "Arrived on time, pleasant staff, but crowded. I arrived in plenty of time to make it to the gate for my connecting flight with no problem."
Cons: "There did seem to have been a problem with the entertainment video not working properly on my side of the plane. Food was more of a snack, which consisted of biscuits or pretzels and a drink."
Pros: "Nothing"
Cons: "spending $600 on a one way flight with you today has been the worst experience and rip off ever! Delayed in Hartford 6 hours. Changed my layover flight in Dallas. Now Dallas delayed 1 hour."

Was charged 99 dollars for a bag despite agents previously telling me it would be ok. Customer service was unhelpful

I will like you ( Frontier Airlines) to fly into LAX instead of ONT because I live in LA and the subway takes me to my house in just 15 minutes

Pros: "We missed the flight due to parking difficulty We came to the airport at 1:10 pm and flight supposed to leave to Ontario at 1:30 pm I requested a flight change or refund But neither refused Please help us to get refund or credit for the next flight Sudath Edirisuriya 916-751-8219"
Cons: "Please provide help to us"
Pros: "Nothing. Maybe the leg room."
Cons: "Everything. Delayed due to frontier poor logistics. Bad updates by staff (ie none), rude gate attendants and rude flight attendants throughout. We did make it an hour late and bags arrived but this felt like a banana republic airline."
Pros: "The plane was timely and clean."
Cons: "It’s suggested to arrive 2hours before your flight, however the check in desk wouldn’t allow anyone to check in and take luggage until 1 hour before the flight began boarding. Keep in mind we still needed to get through security. Was a little annoying but not to awful. The worst part was the seating"
Pros: "The crew was amazing and the communication was great. The flight was not bad and was handled well"
Cons: "The seats were less padded than expected but were surprisingly bigger. They don’t recline. I brought my own “padding” and slept through the flight"
Pros: "Overall a quick flight crew was great always picking up trash it was clean."
Cons: "Only thing I hate and probably will never fly frontier again checking my bag was 50$ and the seats are absolutely uncomfortable I will pay a little more and fly with someone else everytime I fly because after bags it’s not worth it"
Pros: "I like that the plane was on time departure from Ontario in arrival and also on departure from Orlando to Ontario"
Cons: "Some type of entertainment on the plane"
Cons: "Nothing . Nothing at all . Considering I didn’t have to drive, ride a bus , or train . And can get from one side of the country to the other in the time it takes me to get half way through a work day. I’d say any small inconvenience is still well worth the price. And hats off for the TSA . Well done"
Pros: "Inexpensive fare. CLEAR and TSA-PreCheck for security screening a big help at very busy Denver airport."
Cons: "Bag check is expensive at $40/per. Nickel and dime passengers for everything. Fare was cheap so I guess it was worth it. Online check-in was a big pain, since Frontier had incorrect/missing information (name-was that Kayak's fault or Frontier? I don't know.). When I attempted to correct it, they changed my fare to full price. Allowed check-in to timeout and eventually successfully completed without corrections so that fare was unchanged."
