The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

very good but no blankets for overnight flight or tv screens…

We were in 1st Class. Excellent service. Easy boarding. No too difficult to speak with someone on the phone. Breakfast was not eatable for me. No screen to watch movies. I don't have or want a tablet. This is first class there should be screens. Even if I had a tablet there was no place to put it. There is a place to put a tablet in economy. Seats were a bit lumpy.

A cheerful and effective crew. Tasty pre-order food options.

My youngest didn't have a assigned seat until we biard6the plane.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

The flight was delayed by 3 hours and 30 minutes without any explanation.

A little delay but nice flight, nice team. Thank you.

They lock the bathrooms too soon before landing! My bladder was bursting for over an hour. Then the plane had to sit on the taxiway for 1 hour. People started rushing to the bathroom. Creating a dangerous situation.

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Delta flight was on time, seats were comfortable, and crew was nice.

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

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Flight was canceled with no voucher of any kind and next available flight was two days later.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

There were several delays and we were stressed about making our connection. The announcements for boarding were hard to hear or understand. The seating was uncomfortable for a 6 hour flight.

When I was not allowed by Alaska airlines to board due to time and difficulty pre-check the night before and kiosk did not work when I arrived at the airport and then finally told Alaska airlines is where I had to go. Not Hawaiian airlines that they had moved. That's when I was treated with the utmost disrespect by Alaska airlines agent that I was not allowed to board. And that might ticket to return was canceled and I hadn't even left yet when they gave me the option for the next flight to raise my flight price to $300 one way. I bought a $96 round trip ticket and they're trying to gouge me for $600 in addition and canceling my return flight.

Despite two calls as well as a chat on the website, Alaska would not add my TSA number to my reservation. The flight was switched from Hawaiian to Alaska which caused them to mess this up in the first place

The departure gate was changed from C1 to B18 but it was never announced at the C1 gate nor did I receive any email or text message or phone call about the gate change. I was in a window seat. In the other two seats next to me were Mr. Rotund and Ms. Rotunda, a youngish couple. Just the two of them should have booked three seats. I was smashed up against the wall and window for five hours. Overall, I'd say my flight sucked. Wouldn't you?

I couldn't get checked in 24 hours before either leg of my flight. I tried both my Alaska and Hawaiian codes on both apps.

We moved from the international terminal to a new location. I think there are still some bugs to work out . We didn’t receive check in notification and had to scramble to find it but i think it will work out

Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous

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

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

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.

get E+, a must for 5 hours flight if you are tall

The first flight was better in terms of the aircraft.

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.
