I behave had better flights this one was old and poor

See previous. It was the flight from Honolulu to Kapalua that was cancelled.

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

Good. Flight was good. Crew was good. Wish they offered coffee refills. Wish I didn’t have to pay for headphones. Otherwise good for a commercial flight.

My mother suffers from Lupus and has challenges walking. I specifically called Alaska airlines, stated her condition and made sure my mother’s had wheel char assistance towards gate and into the gate hall so she just had to get into the plane and walk a couple of steps. It was assured by Alaska team that the service was granted in both airports , DEN and SAN . In Denver , the wheelchair assistance never arrived. I had to personally grab another airline wheelchair sit my mom.Then I had to go to Alaska Airlines front desk twice to let them know my mother was waiting at the wheelchair service station. Upon arrival to SD Airport , there was no wheelchair service waiting for her in the hall before deplaning. She had to walk her way out in pain. Absolutely inconsiderate and unacceptable by the airline! Never again flying with Alaska Airlines.

Should have been forthcoming for reason for delay. Should have been able to check in for seat I'd like.

It was fine. It was a 30 minute flight so there was water or fruit juice and no food. Which was totally fine. The check in, gate and flight crew were all excellent.

I didn’t order food so can’t really say how it was. Overall, it was a great experience.

It was a pleasant experience. Considering we paid over $3000 for first class there really wasn’t anything special about first class. All the seats looked the same and everyone got the same great customer service. The only thing that was different between first class and couch was the drinks and the meal. We wouldn’t waste that much $ on first class on that plane again.

Waiting 2 hours after landing to arrive at a gate was ridiculous.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

We got exit row seats both flights. Everything was running on time

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Pretty seamless, just a tad bit late in taking off and landing.

Flight was fine other than there was a gate change that I was not notified of. By chance I happened to check my phone and saw the change, otherwise, we would have missed our connecting flight.

Haven’t flown on SW in years. Flight was on time departing and arriving. Served vegan butter onion flavored pretzels which were bad. Coke served was in a tiny paper cup. Crew was not engaging. Felt like they were going through the motions. Old plane, tight seats and no leg room.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

Food is basically Sun Chips, cookies or Cheezits. I had an exit row seat so I had plenty of room. The crew was very nice and efficient. Pilot kept us informed. Pretty good flight.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

Older aircraft, no meal, only food was for purchase. Not impressed United.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Tell the crew (when boarding) to yell at the imbeciles blocking us from walking up to scan. I promise everyone crowds around and half of us (most the time I’m group 4) have to push our way through. Your staff is awesome, the public - not so much-

Bags took over and hour to come out. Delays due to wind caused rebooking.

The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?

Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

UGH I HAD TO MISS MY FIRST FLIGHT TO TAMPA CAUSE OF THE 10 MINUTE DELAY OF THE ORLANDO TO MIAMI ONE SO THEY HAD ME GET ANOTHER TICKET. I AM NOT HAPPY AT ALL BECAUSE IT MADE ME MISS MY CONNECTING FLIGHT FROM TAMPA TO LONDON AND FORCED ME TO MISS A DAY AT MY ROOM IN THE UK.

Wish they didnt delay off-boarding for 10 minutes so i could connect to my flight from miami to tampa

We experienced gate changes and a long delay. My seat was dirty when I boarded and I had to use wipes to clean it myself. There was an unpleasant and overpowering cleaning product scent on the plane as well that lingered through the flight.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

It was fine. My connection in Charlotte to go to WPB was too late and I had to spend the night in the Charlotte Airport in the mini suites.
