It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

8.0 ExcellentPatricia, Mar 2024YVR - SEA
Read more about Delta reviews

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

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

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta needs to step up the meals and snacks. They have been serving the same two meals for three years.... It is time to change it up.

Really liked the choice of the 4 free snack options. Crew great. Good vibe on plane.

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

From the start everything was perfectly fine. First meeting was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast.

We originally had a window seat. Our seats were changed to the center isle between 2 bathrooms. This was a red eye flight and we were traveling with an infant. Due to the light from the bathroom doors opening and closing throughout the night our infant would not sleep and cried the whole night which kept us awake and everyone around us. It was a very unpleasant experience for everyone trying to sleep.

Tai-City to Atlanta :Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation that training was taking place would have been more acceptable, and it felt dehumanizing to him. Atlanta to London: Check in was difficult we had been unable to do this online for 2 of the family members on the same booking both in their mid to late-80s. No seats had been allocated for them and we were all travelling Premium Economy. After several phone calls to the booking agent and conversations with Delta staff at TriCites airport, we were told that seats would be allocated at the gate in Atlanta. When we arrived at Atlanta, and spoke to a member of the boarding staff at the gate, he was curt and repeated back exactly what we had just told him, that only one of us was checked in. I explained that we had been unable to check-in online for the 2 family members (I had tried twice). He again repeated back that we needed to check-in. As we were in transit, I was at a loss at what he wanted us to do, but he kept repeating that we needed to do this. I asked where we should do this. No answer. In fact all he did throughout was look at his screen. He told us that there were no seats in Premium Economy, and that he could offer my parents-in-law 'two seats at the back'. I asked if he meant at the back of Premium Economy, and he replied, 'No, at the back of the plane'. At this point, myself and my father-in-law pointed out that they had paid for Premium Economy tickets and expected seats there. He never took his eyes off the screen once. Then he hit a button and it printed out two boarding passes for my parents-in-law. The seats were directly across from my seat. He had gone from saying there were no seats to somehow finding two together. No explanation, no eye contact, nothing. The flight: As we boarded, our first introduction to the flight was the stewardess at the entrance addressing a passenger with an annoyed and loud voice about a bag that belonged to them. That was not promising. The seats were good, and so were all the accessories. The food, etc.: we had flown with Virgin on our outward journey and I could not fault it. The service and food was excellent, the stewards very helpful, offering additional drinks and snacks. The toilets were more accessible than Delta, which were in the economy area and were told in no uncertain terms that we should not use the First Class toilets, even though they were much closer to our section of the plane. We had a menu for both flights, yet when I asked for the chicken dish on Delta, I was told that there was none left and that there was another chicken dish with mashed potatoes and that 'it was fine'. This was almost pushed on me before I could answer. I was sitting 3 rows from the front of the section, so I was surprised that they had already run out. I repeated that I would like the chicken dish on the menu, and asked whether she would be able to get one from her colleague who was serving in the other aisle. The stewardess replied 'No, that's not how it works!' It always has on previous flights, so I was a bit confused. I accepted that I would have to opt for the pasta option (no choice), but was a little perturbed by her response. Minutes later she returns and hands me the chicken dish I had originally asked for. I had already started eating the other one, but was told curtly that I could have both. This was the same stewardess who was shouting at a passenger as we boarded the plane. The food was very poor in the end, nowhere near as good as Virgin's. Unlike Virgin, there was no starter, no bread roll, just a main and a brownie served in a cardboard container. Virgin had provided real china and glass. Unlike Virgin, they did not return to ask if we wanted more drinks, and there was no tea or coffee served after the meal. The breakfast that was served later was equally poor and inedible, apart from the fruit. At the time, the stewardess, a different one, completely walked past my mother-in-law and did not offer her a hot drink. Both my parents-in-law are in their mid to late 80s, they have been world travellers in their time and had decided that this would be the last flight that they ever take. They have health problems, including memory issues. I feel that overall the journey back to London was pretty unpleasant for them especially, and that they were treated badly, especially by the ground staff. We have lived on two continents and are used to long haul flights, and I have to say that this is up there in the worst flight category. Bearing in mind that we had paid extra money expecting comfort and additional attention, it was extremely disappointing. I would fly Virgin again, but never Delta. The two flights were incomparable.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

The main flight was OK but the second flight was chaotic with delays

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

All the British airways staff were very helpful and friendly. Every thing was very smooth running from checking in boarding and arriving 40 minutes early. Which is a brilliant start to your holiday.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

No nice at all, delayed and I lost the connection over xmas

Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours

good service from crew. Before the would have an option between cookies or nuts as snacks.. Now, there are only cookies. too bad. People who can not have sugar don't have a choice.

Service and food are good. However, main cabin with the extra cost one pays could be better. I don't see any difference with the rest of the seats in the regular category. The seats are too close to the ones in front. For short flights it is Ok, but for long ones there should be more space.

As with every airline the seats are not built for tall people.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I like the team but I don't like the food you provided with money. I want free food and free water.

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

Seats, comfort level ugh. Crew was not attentive, only to coach

Pros: they tried to accommodate bc they forgot my gluten free meal Negatives: The flight was freeeeeezing Iberia didn’t communicate my gluten free meal

This flight was a code share for both Iberia and American Airlines and run by what I assume is a charter company Level. It was difficult if not impossible to get a seat assigned, check bags or use any customer service functions. I would skip it!

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.

Not enough trash pickups throughout the flight. Everything else was great.

Overall good, the gluten free food is very hit/miss though and you must tell them you have an allergy days in advance.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Seating space was crowded and I am a very small woman.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.
