Left a few minutes early. Got in 15 minutes early. Very attentive service on board. Very organized boarding.

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

They double booked seats, the gate staff changed my ticket as I was boarding she went over to the computer and changed it without telling me. She messed up an entire three row section for me and others. Other travelers were outraged but the gate staff were so rude, so condescending saying it wasn't their problem to solve. I would rate this a zero if I could. Will not fly Delta again I'll stick with United and American.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

It was amazing. I had several upgraded seats on my flight out. Everything went smooth with no delays.

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight attendants had a little attitude. Food tastes no good.

Overall we had a good experience during our flight from San Francisco to Houston.

it was a very short flight so my expectations were low.

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

Very disappointing given gate agent behavior. Filed a formal complaint with United.
