One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

They did everything right and everything happened right on time.

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

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.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

I missed my original flight due to miscommunication and it was a challenge to communicate with service personnel, since my Portuguese is limited. However they got me food and a hotel overnight and a seat on the next available flight.

It was a bit unnerving to know that flights are generally oversold. We chose not to pay extra to reserve a specific seat, without realizing that that makes us vulnerable to being bumped. Everything else about the flight was great.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

We liked the way we were treated by the sraff at lima airport counter and the the flight attendants. We did not like the fact that the kiosks at airport rebooted after we entered our information and then told us that there was an issueand we needed to go to the counter. Such a waste of time for a group of 6. Once we got our boarding passes there was no assigned gate so we did not know where to go.

Honestly first time flying with delta and it was pretty good. All the process very smooth and crew was always nice and attentive.

Nothing I like, I missed this connection b/c of an earlier flight delay. I had to stay one more night and I paid out my own pocket. LATAM failed to send me to a safe and decent hotel.

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

LATAM is a great airline who takes care of there guests. They consistently walk around and see if you need water in addition to taking care of all the passengers. The chicken in process is really easy and I’m always offered a chance for an upgrade which I appreciate.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

leg space better than expected. two washrooms for one plane isn't enough.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

The most cramped seating I’ve ever experienced, (including budget airlines) with no food available for purchase on a nearly 6 hour flight.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

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.

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.

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

Very smooth for one of the busiest travel days of the year and the crew was great.

Customer service prior to boarding is horrible Communication regarding boarding gates is released at the last minute and the gates are very distant from Customs. Very disappointing
