First Class seats had no more legroom then Premium Economy. There was no working WiFi or entertainment. I would have rather paid $400 more and flown on United for the 6 hours from EWR to SFO.

First Class seats had no more legroom then Premium Economy. There was no working WiFi or entertainment. I would have rather paid $400 more and flown on United for the 6 hours from EWR to SFO.

I liked that the crew was friendly, we left and arrived at near scheduled times, plenty of on-board crew to handle the cabin service for the flight and I found the price of my airline ticket to be excellent!

The ground crew did not supply drink or snacks during the layover in SFO. So there weren't many options. Otherwise, it was all great.

Had no way to see what gate came in on or what gate connecting flight would take off.

We flew economy, it was what I expected. The seats are too upright for me

I know airlines have to save money, but a little more legroom would be nice. I’m a small person and I just felt cramped after a few hours. However, I loved everything else! Free Alaska Airlines wifi, free movies, yummy snacks, and the crew was so helpful and accommodating!

I love the flight ✈️ Hawaiian Airlines. All stuffs are fantastic members ♡ sweet hearts and families warm welcome 🙏 I have milage of Hawaiian Airlines members so get points .also I booked kayak agent got cheap price ! I satisfied flight with Hawaiian Airlines ♡ thank you

Good, but because I fly internationally I found the food and service lousy compared to European standards. You should include a regular small mean (and not a lousy sandwich) and ear phones. People who travel from Europe are not aware of limited services.

Fine. But given how empty the flight was, I do not understand why my dog, in its carrier, could not be placed on the seat next to me (which was empty) rather than on the floor under seat. This seemed like overkill on the rule following by the flight staff.

Flight from LAX to STS das excellent. Flight from DCA to LAX was troubled by the previous flight returning to the one DCA gate putting our flight in jeopardy. However another gate was arranged and that flight was a bit late, but was handled exceptionally.

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.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

The crew took good care of us. The flight from ATL to SFO is a longer one, and there were multiple beverage offerings. I like the 757's that Delta uses. Good airplane that is comfortable. I do wish Delta would separate Priority boarding from the better seats. I would gladly take a smaller seat in an open row than be jammed into Comfort just to get priority boarding, just to make sure I don't have to check a bag.

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.

I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.

Food was surprisingly good but the WiFi was not great

My flight was extremely cold. I had a jacket and a cover was left in each seat. The cover was extremely thin and I have a disability, fibromyalgia and arthrithis and AC air is the worst. I closed my vent and my husbands vent and it still was frigid. I asked the attendant if I could get another cover and she quickly almost dismissively and totally unconcerned stating, (I quote) (one per chair) and walked off so quickly that I didn't get a chance to explain to her that I literally have adisability. I didnt want to make a seen so I set on that flight for over 5 hours in pain, joints locking up and extremely uncomfortable. When my fibromyalgia flares up my joints not only ache but they will lock up also and it takes me days to get back to my regular self even though I take medication for it. I felt like it would not have hurt anyone at all for her to just give me an extra cover because I'm sure they have all types of medical issues in people that fly every day.

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.

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2
