Paying for first class and then they want $8:00 for wifi.

10 hour delay. Fuel spill. Crew had to drive to Indianapolis to a get a plane. The longest day of travel ever. Poor service.Little to no communication.

Easy flight, crew was polite & observant of all passenger needs as well as safety.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

We were delayed. We spent more time waiting on the plane than actually flying (it’s only a 37 minute flight). Other than that, it was fine.

Only offered water, no snacks provided, and it was cold on the plane, everyone was wearing sweatshirt or jacket in June. I asked for blanket, but crew said they didnt have anything and would turn the heat up, that didn't happen, so for 6 hours I remained cold.

Flight from New Orleans to Seattle to Anchorage was delayed for 3 hours My flight from Seattle to Anchorage was not rescheduled. I had to call the airlines to tell them to get a flight from Seattle to Anchorage they finally got me a flight If I hadn’t been aware of this problem I don’t know how long I would of waited in Seattle to get a flight to Anchorage!!!!!! Return trip from Anchorage to New Orleans in Seattle to New Orleans I was at the right gate when I realized something was wrong they had changed the gate without notifying the change l finally made it on time with minutes to spare & exhausted

I was at risk of not getting on the flight, as when I presented my boarding pass at the gate, it showed me as not having checked in. I was sent to the desk as the last of the other passengers boarded. The agent there said he could see that I had done all of my part and allowed times recommended, but it showed me as not checked in and he couldn't figure out how to correct it. He actually asked them to hold the flight as he struggled with it. He called for support, someone corrected it, and he printed boarding passes for both flights to reduce further issues. I did get on, and needed to ask someone to exit my seat.

Eddie, our flight attendant in the back was excellent. He was very kind and concerned for our happiness and comfort before and during our flight. He made the experience great. We had to deplane due to a ground delay and he made sure we had snacks and water to keep us comfortable while we waited. Overall, it was a great experience!

I liked the food. The WiFi was out and the flight was late.

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Food from the flight from Atlanta to Santiago was very poor..

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Flight left early and arrived early. the whole trip was excellent.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Really disappointed with in flight entertainment, 6 hr flight with no built in screens

I was put in a middle seat with the people on either side of me kept passing their grandchild over me and talking back and forth while I was trying to rest or watch a movie. So inconsiderate and totally disturbing. I asked if they would sit next to each other to alleviate the constant impeding my comfort but they refused.

The flight crew were great. Very helpful and friendly. Seats comfy. Thanks

Overall it was a good flight, but the food should be looked at. No options. The seat was also uncomfortable and very tight.

Late boarding, full flight. Absolutely no food and barely a bag of pretzels. No video screens and slim pickings of movies. No live tv and poor selection of shows.

It’s great, I’ve always fly & ride with Hawaiian Airlines going Inter island or to the mainland.

Flight delays - issues with delays waiting for a gate in Denver

Pre-Flight check-in Staff did a terrific job correcting a seat mis-assignment problem after I checked in the night before my flight. They really stepped up to make my flight home a joy. It was also my birthday, so the flight crew made me feel special a little treat.

Our flight delayed 2 hours, no WiFi in flight and the snack option isn’t great either.

I was unable to get a check im and get a boarding pass. I tried at the desk of the flight operator Alaska, was told to go to Hawaiian and almost had to go back to Alaskan. In the end inwas told to go thru security and directly to the gate without checking in. It would have been more helpful to have the details rather than walking all over the terminals trying to check in.
