Airline reviews
Cons: "Nothing... great flight, uncrowded flight, plenty of extra seats to stretch out. Seat were very comfy and spacious which I loved even got a full can of soda unlike the usual half a cup and done lol. Would definitely fly Jet Blue again and prefer also. Way better than the other carriers."
Cons: "Nothing... great flight, uncrowded flight, plenty of extra seats to stretch out. Seat were very comfy and spacious which I loved even got a full can of soda unlike the usual half a cup and done lol. Would definitely fly Jet Blue again and prefer also. Way better than the other carriers."
Pros: "Crew was excellent. Boarding was great."
Cons: "I had significant delays on both the flight to Logan & the flight back to Charlotte."
Pros: "crew was great."
Cons: "flight was 3 hours late with lame excuse. tray tables disgusting. felt unclean. cookies tasted gross. pa system not working. live flight not working either"
Pros: "Crew was nice and accommodating. Plenty of leg room in regular cabin. Good entertainment options.?"
Cons: "We waited in the runway for 2 hours after landing. Not the airlines fault however completely unacceptable."
Pros: "Everyone was boarded early so we departed early. Quick flight with pleasant flight attendants and nice snacks."
Cons: "The desk agent in Boston could be a little more pleasant."
Pros: "Crew was nice. legroom seemed a little better than other domestic flights."
Cons: "You have to pay extra to sit in the exit row and there was no one in the entire row. Isn’t that a safery issue? Also, what really made me mad, instead of printing our boarding passes at the kiosk we went to a person (husbend had questions about Precheck) and she made us buy return tickets right then, on JetBlue. We had not decided on our return and wanted to leave it open. Can she do that? If not, I would like my money back."
Pros: "Boarding was great and on-time. Flight took a bit longer due to the weather."
Cons: "Couldn't understand any of the in-flight announcements. My in-flight entertainment didn't work right."
Pros: "Seats are very comfortable"
Cons: "The flight is so much delayed. The flight attendent seemed not happy about me with a two year old, which makes traveling with a kid so unpleasant. When my kid asked to go to restroom, it seemed that we’re troulesome. My mom missed the water when they gave out drinks, but they did not come back for us. When I went to the back to ask for my mom, they said they’re cleaning up already."
Pros: "Friendly staff and a smooth takeoff and landing. All I could ask for. This was the 1st time that I flew JetBlue and I was impressed."
Cons: "The middle seat but that was probably my fault."
Pros: "The crew was great. The pilots too."
Cons: "The audio and video at my seat did not work correctly."
Cons: "Nothing, really. Airlines unfortunately can’t make people patient or polite, & I can’t afford a private jet, so I’ll have to settle for an eye roll or twelve."
Cons: "During this trip all my flights got delayed and I was told that I could not get a hotel room and had to pay for myself."
Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."
Pros: "The only thing I liked about the experience and flight was the Delta Sky Club"
Cons: "Everything"
Pros: "Seat was hard, not much foot space"
Cons: "My wife and Iasked for a snack, it was never delivered"
Pros: "Seating was fine"
Cons: "Did not have a wheelchair waiting for my wife when we arrived in LAX"
Pros: "Crew was friendly"
Cons: "An hour and a half late, terrible communication about scheduling"
Cons: "Even the baggage was quick (highly unusual for Columbus, Ohio)! Everything went smoothly."
Pros: "nice crew"
Cons: "terrible seat comfort, late departure due to airline’s booking problems"
Great flight, comfort, and staff. Prefer tv in back of seat but watching on phone will do
Pros: "Friendly staff and the support they offered to my mother who needed a wheelchair."
Cons: "I would have liked to have had WestJet internet and entertainment access. It was not offered on our flight from Toronto to Fredericton."
Pros: "The fact that military personnel and retired military personnel and their spouse can check in luggage for free. The check in crew was also very courteous."
Pros: "It ran on time. The pilot landed the plane without a big jolt. We could board and deplane using 2 exits."
Cons: "Seat space"
Pros: "Great, friendly crew in this scenic trip across to Victoria. Nice new aircraft operating this route."
Pros: "Cheerfulness of WestJet employees."
Cons: "Seat comfort; seats hard. Person next to me average size but still spilled into my seat with “man-spreading” and shoulders."
Pros: "Efficient crew and reasonable seating"
Cons: "Need more legroom or a device to fold passenger legs for the flight duration..."
Pros: "the crew was very polite but the flight was too short to have a meal"
Cons: "delayed embarking"
Cons: "No plugs to charge phone. Though flight was budget class, other airlines does it better when it comes to food."
Pros: "The crew were great! Ingrid was so sweet as soon as I stepped on board !"
Pros: "seat space was great and I was lucky enough to have medium size passenger next to me :-)"
Cons: "Can't really think of anything . . . my expectations were exceeded"
Cons: "The aircraft was old and in need of some work. Nice crew and smooth flight. Just aging equipment."
Pros: "Free open seats"
Cons: "Opd plane. USB ports only in Comfort Plus and above"
Pros: "Preflight announcement on smart bags. Beverage servive god. Snack could be more than 2 cookies."
Cons: "2 flights need more than 2 cookies."
Pros: "Staff was great and service friendly. The flight attendants were truly exceptional."
Pros: "Good flight. Nice staff."
Cons: "Old plane with obviously dated cabin, questionable cleanliness, smaller than average seats. Short flight without beverage service (understandably so)"
Cons: "SeAts too close to each other. The girl next to me kept hitting me with her elbow the whole time."
Cons: "I missed my outbound flight from Chicago to Dallas, and although I called to inform Delta, my return trip was cancelled and i did not find out until the day of my return to Chicago. When I called Delta to figure out what was going on, I was put on hold for two and a half hours. I'm not giving the flight a bad review, since I never got on the plane, but I'm disappointed with the accuracy and care for customers that I've experienced with Delta service. Delta was the first company I've ever flown with when I first started travelling when I was twelve years old, and it is unfortunate that I will probably never book with Delta again."
Pros: "I've done many flights this distance, and just take for granted that there will be entertainment. There wasn't."
Pros: "Unfortunately there were unavoidable delays due to weather but the staff gave regular updates and were very honest. Also, they brought out food and drinks for people bc they knew people wouldn't feel comfortable leaving the gate in case of changes. Staff handled the whole situation very well."
Cons: "We sat on the plane for a (scheduled) hour before take-off. What gives?!"
Pros: "Flight departed on schedule and arrived before scheduled. Attendants were courteous and helpful."
Cons: "Very cramped seating. Was OK for short flight, but would be very uncomfortable for longer flights. $3.00 for a drink of water!"
Pros: "Crew was friendly and helpful. The setting was such that I could read when I wanted to read and rest when I wanted to rest."
Cons: "I missed not having a flight tracker. Otherwise I really can't think of any negatives."
Pros: "Mostly to be expected."
Cons: "Delayed flight but no communication of this. Had to check online."
Pros: "The crew was polite"
Cons: "Literaly everything besides the crew was sub-par. Deterred me from flying spirit again. Seats were very uncomfortable and did not recline"
Pros: "Nothing at all"
Cons: "Who bumps you off a domestic flight if you're not already checked into 2 hours ahead of time? Spirit that's who. The adage is true, you get what you pay for. We paid for a scam with spirit. They apparently have an odd policing if you haven't checked in at the airport 2 hours ahead of your flight, you don't get to fly. No one alerted us to this policy and spirit even double down on the claim the my didn't have our contact information to alert us while I was actively receiving texts from them. Did nothing to try and help us. Pay more elsewhere. It will save you in he long run."
Cons: "ALL THE ADDITIONAL FEES, including bags, picking seats, and soda on board! Seems misleading"
Cons: "The fact that Spirit didn't let me board my flight or reimburse me or put me on another flight unless I payed a $99 fee."
Pros: "left on time"
Cons: "too small seat selctions-felt ike sardines in a can"
Cons: "I went to the airport 35 min before the flight left with no luggage. I was told that Airline policy is to cutoff at 45 minutes and so they did not give me a boarding pass. I asked for alternative arrangements. They said that they can give me a ticket for a flight 48 hours later. They also said that they do not partner with other airlines so they cannot help. I purchased a ticket with another airline and left a few hours later. The staff told me that this is an everyday occurrence. Policies are fine but the staff should provide alternate solutions."
