Boarding was well organized, seats comfortable & it was a very pleasant flight
Low cost, but I think I really wanted an aisle seat, and I could not easily get one. The return leg might be easier.
Trip from SNA to SFO and back was riddled with DELAYS.
Flight there was massively delayed but never updated on the app. Flight home was massively delayed but also never reported until after we arrived at the airport.
Gate agent and flight crew were amazing! Only issue was landing and waiting on the run way for 30 mins to deplane.
It was all a wonderful experience. I hate to fly and I hate to travel yet. This was a very pleasurable event. Thank you.
Flight cancelled originally with no email informing me of the change. Rebooked for the next day and that flight was delayed with no update on the app.
Sat next to toilet after booking with kayak. Last seat last row
Poor transfer conditions at LAX almost missed flight. Long walk and delayed shuttle ..avoid at all costs
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
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.
It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.
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
My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.
No screens or meal options. Freezing cold. Dirty seats. Left late.
Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time
It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.
Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.
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
The plane was spartan, the seats not that comfortable. It was like flying a super low budget airline. They charged for coffee!!! I have never, ever experienced that before.
I had no problems but the changing of planes that I was supposed to be on was confusing. Maybe it would be helpful to let people know your flight changed. Not everyone understands airports or how flying works.
Flight was delayed multiple times without giving any particular reason and the only thing that was communicated was that 'Aircraft is getting ready'. I was stuck at SFO airport for 15 hours and finally took Southwest Airlines flight back home to Dallas.
I was not clear if food was offered or not.
Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week
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.
