Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

My son’s suitcase was left behind at SFO and did not make the flight.

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

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The pilot was late so we didn’t take off til almost 2 hours late.

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.

Excellent communication from the staff. We actually arrived early. Very friendly and professional staff.

No extra snacks were available. Meals quality is terrible. Crew was not friendly.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

It was perfect! United Airlines staff was extremely caring, super friendly and professional

United has maintenance issues and can then never recover. No operations ability and simple issues always turn into multiple hours long cascading delays. Worst airline on earth.

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

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

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

The seats were roomier than other airplanes I’ve been on.

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.

It was inexplicably canceled and we are stuck in LA, haven't gotten home and it has been an inconvenience having lost work (on unpaid leave for my husband).

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!

the staff was very helpful and the airline was very good.

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 food was okay and the space in business class was smaller than we had to Singapore.

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.

Flight delayed 3 times due to maintenance (on exact same plane that had just brought us from Boston to Miami). Eventually changed to a different plane and gate.

Both flights were delayed. One by an hour and the other by 1 1/2 hours after boarding.
