Was revoked with Jet Blue due to delay from Kenya Air

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

It took so long to do a baggage drop and it was bad enough. I had to go to the extreme end of the terminal because it’s a USA flight and go all the way back to the center indigo to security.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

The clerk at check in for my bags was very rude. My credit card was hacked during my vacation and she told me it was not possible to pay in cash for my bag. “You bought the cheapest ticket, you should have bought a ticket that included a bag. If you cannot pay with a credit card, we will not let you on this flight”. She spoke to her supervisor and then told me , I could ask other passengers, if they would use their credit card to check my bag. I had to beg 5 different people, till one agreed to use their credit card. I payed them cash of course. This was a very stressful and humiliating experience for me. I strongly suggest you build in some kind of provision for travelers who got robbed.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

boarded early to only find out that flight would sit at gate for 45 min to an hour. Landed in chicago and sat on runway for over an hour before got to gate. Total delay was extensive for a 45 min flight door to door.

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

Excellent plane, 787. Very good seat and additional stuff they provide. Good food. Very good staff.

Excellent except WiFi is a Must on Biz class 10 hour flight ! Didn’t work entire flight. SW doesn’t do that.

Excellent crew, food and service. Boarding via bus is always a pain but overall really good

Stewardess was not attentive at all asked for a bottle of water never came by 15 minutes later I asked her she said that she forgot there was only 12 people in first class and two stewardess unacceptable I ordered the fish was the last person to order. They said that they did not have any had to have a different item pasta at the inside of it because I was diabetic. Worst experience I ever had will never travel this airline again.

Very nice staff, terrible food, not very comfortable premium economy.

Boarding, crew, food and baggage handling excellent (no bags lost, yay!). However for an 8 hour flight, there were limited entertainment options. And really would have liked to have a pillow!

The crew was super friendly and helpful. The food was quite good. An overall positive experience.

A more organized boarding experience and better food would have made the experience better.

why can't planes be boarded from back to front?? everything was great otherwise

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

Come on. A two hour, 7am flight and a small bottle of water and a tiny chocolate bar was provided. No coffee, no nothing. Poor.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Long line with check in at the DIA British Airway counter.

The flight from Dallas to madrid was delayed for 2 to 3 hours, the flight back from Dallas to Sacramento was fine , but there were 5 gate changes within the span of 2 hours, last one was in a differny terminal. Flight and crew was okay

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

I loved the food choices and the attentiveness of the crew but boarding was chaotic.

Check-in experience, for business call please provide a premium experience

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Everything. Employees offered to help me because I had to use a cane.

Awful. Flight was late. Follow flights cancelled. No person at the British airways counter for hotel voucher. Awful service.

Well unfortunately our connecting was cancelled and next flight delayed. Was in airport 9 hours. Flight itself was good. I’m sure it was a FAA problem.
