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.

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.

Logan airport construction meant that boarding was chaotic crowded and delayed

Everything was great. Great service, excellent communication, and early arrival

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Free Wi-Fi is good. That’s all - food mediocre, unfriendly crew, poor communication after trying to file a claim for my lost bag, which Delta didn’t even know was lost until I told them.

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

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

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

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

horrible website for checking in- no option just to write the passport number; ludicrous

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?!?

Nothing, whole flight was a nightmare, was forced to check my carryon bag at the gate, staff was rude and unprofessional

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

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

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

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.

Typically, I am always impressed with American personnel. These you run into the rude old hags that are still around. I can tell over my 40 years of flying with them, they have made strides in improving their attitudes.

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 seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride. At boarding, the staff could have more pleasant even though it may be an intense time.

Lots of announcements that no wheeled carry on bags were allowed on the flight, yet the overhead bins were totally full and made it uncomfortable trying to get through and significantly held up departure. Why were they allowed on when they said that they weren't? Trash only came by soon after service and I wasn't ready to dispose of it. I had to first hold on to it and after flagging and attendant was told to stuff it in the seat back! I have never run into the need to walk outside in northern winter weather at an international airport and wasn't dressed to do so in the cold pouring rain! I'm not thinking that I'll be back unless I hear things have changed.

My first flight left so late we knew I would miss my connection. Rather than redirecting me then, they made me take a flight to Montreal, then Toronto (there was a flight leaving for Toronto when I was in NYC, no need for me to also go to montreal). Then they gave me a food voucher that did not work (4 places would not accept it). At least they gave me a hotel automatically, even though it was a cheap crappy one. I'm still not home, and it's been over 24 hours. I'm exhausted.

Liked the size of seats. Not much food offered given length of flight.

The boarding was at a dual gate hallway and there was only one spoken explanation about which way to turn to board the correct plane. It wasn't marked visually at the split in the gate. The phone charger did not work at my seat. The temperature was quite chilly throughout the flight and the recorded announcements were extremely loud for a small plane.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!

Flight was delayed 1.5 hours as crew was stuck in traffic...that is absurd that the airline would be transfering a crew by car through NYC during rush hour. I missed my shuttle bus and got stuck in Vancouver for the night. Airline did not offer a voucher

I booked these flights for our group of 4 people several months in advance. On the departing flight, I checked in 24 hours before flight and was able to select the seats that we liked. On the return flight, I had no internet access until about 12 hours before flight, when I tried to check in, we were scattered all over the plane in middle seats which is absolutely ridiculous. I book all 4 ticket in 1 booking MONTHS in advance, the preassigned seats should be together, NOT scattered in 4 different rows in middle seats.

Very unfriendly crew, Air Canada should hire staff that are willing to do their job and be friendly to others. Unmannered flight attendants.

It was absolutely awful in every week. A mechanical failure led to a 6 hour delay, cancellation and rerouting.

On the short flight it was fine . The flight was smooth and crew pleasant .

My flight was late. We stayed in aircraft one hour 😩

Flight delay and can’t much help passenger do the change connecting flight.

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

5 days later I have not yet received my luggage so terrible and unacceptable

Easy and quick check in, clean and nice seats. Overall excellent experience.

The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.

Great job notifying of 30 minute delay in departure. Fabulous job making up for the time and arriving as scheduled. Air travel is just no fun anymore with the extreme overcrowding, and someone needs to come up with an innovative plan for loading and unloading passengers (load all window seats first, middle seats second, aisle seats last?). Great job getting the luggage on the carousel in record time!

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

It was good but I wished if they could have sign do not disturb if we did not wanted any meals . I was tired and slept through the entire flight and woke up just before landing .being hungry Too late to ask for something to eat before exiting the flight . Left feeling hunger 🙁
