It was not clear the check in shd be at Hawaiian Terminal 1. I got dropped off at Alaska Terminal 2. I did the long walk from terminal 2 to 1. Fortunately I didn’t have a check in bag.

Unfortunately 4 hour 40 minute delay because of airport then one hour into flight diverted back to Kona elderly man on plane got heart attack trying to get home some how

Why was I charged for a glass of wine on one flight and not on another? Why no movie or TVs? It was a long flight.

Hawaiian Airlines, like most US-based ones, constantly provide sub-par service and pack their planes to the max with all kinds of last-minute-purchase schemes. As a result, it makes every flight so uncomfortable and generates high health risk for its passengers. In one word, GREED rules the day!

5 1/2 hour trip. Nice plane. easy boarding. Could have used a bit more beverage service but it was a red eye flight and they didn't want to wake everyone.

Terrible airport. It took over one hour to pass checkpoint and security gate. We stood under the sun in the long line

Reserved seats and yet did not get my original seat because someone else was seating in them and the crew member did not try to find out what was going on with the issue. My wife and I did get similar seats. This created concern and unnecessary issues.

When I booked with Kayak, I paid extra for a window seat for the long flight, so I could sleep more easily. But when I checked in, they changed my seat to a middle seat. This happened on both long flights to and from Chicago to Anchorage. For one flight, upon request they changed my seat back to a window seat. For the other, they would not and said the Alaska Airlines does not allow seat requests.....just disappointing.

All airlines seem to be a scam with having to pay force assignment, baggage fees, and completely garbage food. Our flight attendants now seem to have a power trip complex. It’s clear they know we have no other choice if we want to travel so they don’t care and let you know it.

Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

After being assaulted by a flight attendant I was then brushed off as oh well because he long braids didn’t mean to whip me in the eye. I have filed complaints and will see. But like any other issue I’ve had with kayak involved it’s been trash. Last time I’ll be using your app

AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

Southwest's seats are the least comfortable I have ever sat in.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Overall it was good. I missed my connection but I was put on another flight.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.
