Crew was real good, flight was smooth and came in early.

Gate agent rushed to fill hot jetway with crowd so it took over 12 minutes to go from gate to plane. Just like a discount airline Pooly prepared cabin and third time that claim of rough air prevented any cabin service. Friends on a Southwest flight at similar time had service.

Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Was a great smooth flight from Detroit to San Diego.

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

They made us check our bag…. Even though there was plenty of space up top… and then proceeded to shatter by brand new luggage 😞

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

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

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Nice crew - very small plane and uncomfortable, with no entertainment options…

We were given an upgrade which provided more seat room and a meal. However seat designated overhead locker space was used by others.Boarding was delayed with part or the delay due to staff assisting diaablef individuals aboard. Personal observation would suggest that 3 individuals rorted the system. They used wheel chair access to the plane, boarding with family ahead of al other passengers, but required no assistance until boarding occurred. On departure 3 “disabled” individuals were seen walking freely near the baggage carousel. One person even assisted with a luggage trolley! The rorting is most likely widespread and not airline specific

Not good with Kayak … There is no customer service number to call ?? We have stuck at Toronto airport but air Canada don’t help because we bought tickets thru Kayak .. Kayak should have customer service number listed for help .. Very bad .. we will think twice to buy the tickets thru Kayak next time.. Ahluwalia

We paid $110 for more leg room. My traveling companion’s knees were right up against the seat in front. Where was more leg room. We feel ripped off. Food,,,there wasn’t any not even a bag of pretzels. As a result, there was very little service.

A 6 hour flt and only offered water twice the entire flight. A small bag of flavored pretzels was offered as well w/ the first round of beverages. The landing was ‘hot’ but I arrived safely. The plane was nice and new and the seats were roomie. I’m use to warmer more generous hospitality but all and all I’d fly with them again but I’d bring more water and snacks.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

Air Canada didn't properly check the maintenance status of the plane prior to boarding it's passengers on to the plane. A final check before liftoff and we had to switch planes because of mechanical flaps issue.

In the airport of Toronto, the person in charge a man with beard was an stupid person, he send everything to caos. Not helpful at all. Sunday to from 6:00 am to 8:20 am he was there, a people who work in front desk cannot be stupid and with that Ego !!

The check-in process was a disaster. 2 hours to check-in for PRIORITY boarding. We have never in over 40 years of travel experienced such a poor and lengthy check-in. Luckily, security and customs was nearly empty so we could breeze through it, and they intentionally delayed the plane half an hour to allow passengers to make it. The rest of the flight was as expected (in business class). But our luggage never made it to San Diego. We tried to locate and Air Canada rep at baggage claim but we were told that no one from AC showed up that day. I had to make a claim for our luggage by calling in to baggage services with AC and I was told that only because I had 75k travel status with AC would I get my luggage this week. Let’s see! I know many people that were waiting in line with me at Pierson missed their flights. Total disaster at Pierson this week.
