WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.
Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.
Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.
Crew was absolutely fantastic and we’re so welcoming and friendly ❤️
Flight delayed four separate times. I’m now one hour hours late to landing.
The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.
Awesome! On time flight, early arrival, and a complimentary upgrade!
Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.
Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer
New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home
One of my checked luggage was damaged. Cracked on the top by the handle.
I have been flying united for a long time but now I’m done
Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.
Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.
Lost one piece of luggage even though I checked in 2.5 hours before the flight
Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms
They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service
They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.
Flight was delayed 3 hours. No food on plane besides snacks
I have flown Jet Blue many times between JFK and SFO. I appreciate how clean the planes are, the ability to select my onboard entertainment and the flight crews have always been amazing! Unfortunately, my trip from SFO to JFK on August 23 was unusual. I arrived early at SFO for the 12:00 noon scheduled boarding. The flight was supposed to take off at 12:45pm but after sitting for a while, the plane had to return to the gate to have a generator inspected. After deplaning and then reboarding, we eventually took off around 3:30 pm. It was explained to the passengers that because the plane was using a backup generator, additional fuel was needed and the flight would take longer than originally scheduled. We were originally supposed to arrive at JFK at 9:32 pm but instead, arrived at midnight. Unfortunately, I was exhausted for the funeral I attended the next morning. As a passenger, I have always expected that the plane will be in good mechanical order and that all parts will function as expected. I'm not entirely certain that if I fly Jet Blue in the future, that I will have the same level of confidence that I had become accustomed to. Thanks for the opportunity to provide this feedback.

Seats were great, the staff was great, and the food was about the best I've had on a plane, and is especially the best of any US-based carrier I've flown. Free Wi-Fi was also great.
Rude crew member. She seemed annoyed at me without me saying a single word. Also loudly admonished me for having my bag next to my seat instead of tucked away before landing. Just telling me to put it away and guiding me without giving me a lecture would have been enough.
Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.
Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.
I really liked the way snacks and drinks were available throughout the flight!!! The flight attendants were also all fantastic!
Always like Jet Blue! It seems, however, that people are getting bigger & seats are getting smaller! We had a very full flight and I couldn't get an aisle seat like I always do. I wish there were more leg room. People sitting next to me were very nice though so it was fine to disturb them if I needed to use the restroom. Otherwise the flight was fine but a bit long.
None of the in flight Direct TV worked. A better selection of Shows would have been better. The baggage was s low. Otherwise we enjoyed our flight!
No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.
Multiple delays and made us miss the connecting flight and lost our bags
Little communication with passengers after sitting over 1 hour for a maintenance issue Then we had to deplane- no crew communication Poor gate information after deplaned WiFi would not connect AT ALL
Flight attendant made the flight very enjoyable. He was courteous and gave great care to the passengers
Not good. Flight crew, was not friendly and just shoved stuff at us. Not the way I like to travel.
Aside from the little delay, overall was flight good. Made it safely. Thanks!
Over the course of 7 months of travel, I can count on my hand the number of times the flight has departed on time. Majority of the instances have been related to non-weather reasons. Would not recommend flying this Airline
It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.
It was the worst experience ever. Cabin temperature cold, for which they did not have any blankets upon my asking. We paid $125 extra for each passenger to get extra space sits; the sits were ridiculously small, tight, and uncomfortable! The flight attendant dropped ice on me and my sister! All in all, American Airlines deserves below zero!
No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.
I really didn't like anything. Paid for my checked luggage online ($79) and then was told that I would have to paid another $79 for my carry on. Was not allowed to enter the terminal until 3 hours before my flight and when I finally was allowed to check my bag and enter, my flight was delayed 3 times. When I finally landed, we were all instructed to "run off the plane" as they had to do a quick turn around to Las Vegas. Me and several of my flying companions will never fly Frontier again.
They didn’t offer a water, even after I asked
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.
While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!
Stop changing gates at sfo. When you are elderly going back for it’s not fun.
After 5 hours of delay, they cancelled the flight. Very disappointed
My flight to LA was cancelled. I waited at the airport for 3 hrs saying it was delayed and then all of a sudden it was cancelled. Frontier only gave me a voucher and refund but could not rebook me. Flights on other airlines were too expensive last minute. I had to drive down to LA and didn’t even take my return flight home since I had to drive. One of the worst airline experiences in my life. It’s crazy how airlines can just upend people’s plans just like that.
