Airline reviews

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

I think they can provide the better food/snack option for the 4 hours flight. Drinks are fine.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The seats are uncomfortable, feels like a small seat pad on plywood.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

I notice that every time I fly delta or any American carrier, the staff seem tired, overworked, and not at the service level I’m accustomed to in Asia. They frequently crash into my arm when coming down the aisle. Food is shoved at my face with no greeting or verbal cue. The food portions seemed much smaller than usual and didn’t see much wine or beverage options. This is comfort plus? The plane was old and tired. The bathroom was dripping with mineral stains after a long lack of cleaning. The power socket did not work, although the USB output did. I really wonder why I’m flying Delta, I think it’s time to switch to ANA.

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

It was fine. no food or entertainment , but was only a 40 minute flight.

Paper boarding passes needed, so you need to add the time at the kiosk or desk to get them at the airport

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

The crew was super friendly and respectful, they made me feel well all the fly , thanks delta

No food optional ( they offer just pasta, no second option, the soda without carbonation, I asked for snacks and they said give a minute, I never got it) I believe they (crew) don't care about it (people)

The seats are getting smaller and smaller. Very uncomfortable trip. More than in other airlines

The crew was amazing. The best in the last times. Great group of people.

Check-in was a total disaster, almos a full hour in the line

Just some cookies and water. There could be other options for food.

We arrived early and finally made it to our gate almost an hour after.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

The flight was delayed so the people from a late connecting flight was able to still make the connection.

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

David went above and beyond to make our flight the best that it could be

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

Flight areas delayed 3 hours , train in the airport didn’t work

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

Flight was on time Crew was not. very friendly I paid for premium class and It wasn’t too much different from coach

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.
