Pros: "Jet blue flights seem generally good. Like the WiFi access to be Able to use flight time efficiently."
Pros: "The available movies were pretty good."
Cons: "The crew member serving the food was way too slow."
Cons: "Flight was 3 1/2 hours delayed. In-flight entertainment system didn’t function. They didn’t perform a beverage/snack service. Very poor overall. Disappointing."
Cons: "Our flight was delayed 4 times. We then sat on the runway for an extra 45 minutes because someone’s tv did not work. We missed our set transportation which was already rescheduled 4 times and had to pay $150 Uber to get home"
Cons: "They had to reset entertainment sets 3 times before they started working. This happens regularly on the SFO to BOS jetblue flight."
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: "Great crew and service"
Cons: "The delay was longgg but I know that couldn’t be avoided"
Pros: "Very smooth flight and all the staff were really nice."
Pros: "Flight attendant at the front with the glasses was excellent"
Cons: "The flight attendant at the front- I don’t know her name but she was wonderful, friendly and smiling and seemed genuinely pleased at her job. The flight attendant in the back I don’t believe smiled once the whole flight. It was a relatively short flight but still not one smile on boarding, in flight or once we landed. Probably gave the most morose safety demonstration in aviation history. I know most people don’t like their jobs but a smile does go a long way and for me personally it helps s great deal when you have an irrational fear of flying. She did nothing wrong but she could have at least looked like she wanted to be there."
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
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: "Flight was smooth, arrived early..crew was prompt and courteous."
Cons: "Wheelchair shortage on arrival, although I had one reserved. Waited for a while then walked. Not ideal. Very long wait for bus to rental car center."
Cons: "We thought we were flying AirFrance as our emails came from them and were surprised to learn after waiting in the AirFrance baggage drop queue for 30 mins that we were in the wrong place."
Cons: "Double booking and payment of flight. Dropped flight bookings. Not a good trip"
Cons: "the inefficiency and extra steps required to travel. Quite lacking in smooth transition between flights, significantly below expectations relative to other airlines"
Pros: "The crew was super nice, they offer me to change my seat to fly with my sister."
Cons: "The pilot"
Pros: "On time"
Cons: "Tiny seats, no snack or napkin with the drink. Noise in back."
Pros: "The flight was crowded, but what can you expect? Turbulence prevented beverage service. The flight arrived early but had to wait to land."
Cons: "inflight entertainment wasn't working on my seat only which made my 6 hour flight seem even longer :("
Pros: "Wi-Fi was great. Watched two movies. Flight was on time and painless"
Cons: "Only complimentary snack was pretzels and only a cup of water."
Pros: "Despite getting no updates, our flight itinerary was changed from a 3.30pm flight to a 9.20pm flight. Unfortunately this was after landing from Milan at 1.30 with two small children so we had already had a very long day. We absolutely never would have booked this flight itinerary had we known of the change."
Cons: "I am beyond stunned that our flight itinerary was changed from 3.30pm to 9.20pm with no notification. This is absolutely unreasonable and inexcusable made even worse that we had already had a very long journey from Milan to JFK with two small children. Evidently the issue was that we booked via a 3rd party off the kayak site and not directly with British airways. When American airways changed the flight from 3.30 to 3.25, the 3rd party company failed to file for our updated itinerary so British air/American air bumped us to the next flight at 9.20pm. We have long been loyal to kayak feeling it provides the best breadth of options and good pricing. Now we may use kayak to see all the options but I can’t booking directly with kayak anymore after this complete disaster. We ended up renting a car and driving from jfk to Boston, getting home 23 hours after our journey had started, stressed, beyond exhausted and now have to return the rental car. Thanks kayak."
Cons: "We flew from Rome to JFK and arrived at 12:40 pm only to find out that our 3:30 pm flight had been cancelled a long time ago. No one had notified us of our new booking on a 9:10 flight to Boston. No one at American or British Airways could provide us with an earlier departure or compensate us to take alternative transportation. Our 9:10 flight was then delayed until 10:50 pm. We arrived in Boston at 12:02 am, 11 1/2 hours after our arrival at JFK from Rome. This was not a very friendly welcome home. We never would have booked such an extended delay as we only live 4 hours from New York City."
Pros: "One was great and one was not helpful and was condescending"
Pros: "Plane was new and entertainment was free. Great service too."
Cons: "American has improved a lot"
Pros: "Staff was polite and friendly. It was a great experience!"
Pros: "There was a large range of entertainment options. Enjoyed the seatback screens."
Cons: "We were on the plane for an hour before taking off."
Cons: "The new plane has no usable pouch to put small items in during takeoff and landing - you have to hold everything now, as the cargo net they use barely opens. As hard as the crew hammers you to put things away, having that pouch is handy. Also, we all know we are crammed in too tight."
Cons: "The delay was horrible and the captain said it was because they needed extra sleep. I found this offensive as i was trying to complete a very long trip and was exhausted."
Pros: "Seats were pretty comfortable"
Cons: "In-flight entertainment depended on the Wi-Fi working. It did not work the whole flight."
Pros: "We landed in NYC -- although it was first announced as Dulles."
Cons: "This flight was on Canadian Air under the auspices of United. I was not allowed into the United Club lounge despite the fact that I had business class ticket. I was informed that a business class ticket isn't sufficient for using the lounge when flying domestic. It is only good when flying international. They call that customer service. I generally avoid domestic airlines because of the customer service. The flight attendants were not happy to serve you. It's a small flight but they didn't even offer a snack -- you had to ask for it. And then they brought over a small basket with nuts, chips, candy bars, and a muffin. I took a muffin and it stuck to the roof of my mouth -- very poor quality. When I asked for a snack the flight attendant replied cocktail or soft drink never saying whether or not a snack was available.. She said this a couple of times before I could repeat that I wanted a snack to which she replied you want something to drink with that. I've been on many short flights in Asia and they will deliver a full meal and you don't have to ask for it. There was no entertainment but United did send an email explaining how I could purchase entertainment to play on my own device."
Cons: "It appears united is unable to fly their planes on times, in particular on the East Coast. We were delayed by 90min on each legs"
Pros: "I did arrive in Boston, eventually."
Cons: "The flight took off approximately 3.5 hours behind schedule and we boarded the flight and waited inside the aircraft for 2.5 hours...why did they do that? The flight attendants were offering water and trying to be as helpful as they could be.... but we're inside the plane, not going anywhere, so not much extra they can do."
Cons: "The flight was delayed by five hours due to a mechanical problem with the plane. Little information was provided by United. Frustrating experience."
Pros: "The flight departure was on time and boarding did not seem as challenging to me. Newer aircraft and very friendly crew. Is the friendly skies back?"
Pros: "Quick flight, faster than schedule. Flight attendant was good."
Cons: "Absolutely no leg room or arm space in the seats on US express jets. If the flight were longer than an hour it would make for an absolutely miserable experience."
