Airline reviews

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

I paid for WiFi but it never really worked. That was frustrating.

My flight from Spokane to Seattle was delayed about 26 minutes. I arrived at Seattle Airport at 3:21. My flight to Idaho Falls left at 3:35 and you all wouldn't wait for me. I ran for the gate and It would have cost you probably 10 min to wait. Now, I'm stuck at the Seattle airport for 5 hours. I would understand if waiting put you 30 min behind or an hour but I checked into that flight, you knew I was coming, and that my flight was delayed.

Honestly the bathroom cabinet under sink fell out and was completely broken. The floor or walkway was worn out and it smelled wierd. But the seats were terrible for comfort. I truly hope that my trip home in February is better.

My first flight was delayed by over an hour, luckily I had Long layovers on an itinerary from hell, because when you book a Saver ticket, they change your itinerary and make it many stops and long layovers, and there were still delays. On the return flight there was a delay in the first leg, Orlando to Seattle, so I got up really early for nothing, and on the last leg Anchorage to Fairbanks, it was over 2 hours late taking off! I didn't get home until 1 :30am! By the time I got my luggage, the flight landed at 1 am. For the departure day, I was up from 6am to when I arrived the next day at 6am in Orlando. So I was up for 22 hours, 3:15am to almost 2 am the next day. On the return day. The moral of the story is, DON"T EVER BUY SAVER TICKETS! You can't even upgrade your seat when you do that and then at the last minute they want Big bucks to upgrade the day before leaving.

I had the worst seat neighbors thry literally snored so loud and the man next to me man spreaded the whole time i couldnt sleep

Service was great! 👍 Seats were small and absolutely not enough leg and feet room!!!

We sat on the tarmac for so long when we got to SeaTac that half the plane missed their connections.

Packed flight, cabin was so hot and stuffy that a woman fainted in the aisle. Crew were so inattentive that it took a awhile for just 1 Crew member to respond. Seat was incredibly cramped. Made to check bag because of "no overhead room" but there was plenty of overhead space when I was one of the last to board. Why is someone in boarding class A-D entitled to carry-on space but people in class E-F aren't? Whole flight was very uncomfortable. Shitty flight with a shitty airline. No more Alaska airlines for me.

The boarding was quick, but the cabin was uncomfortable and I got stuck in the galley while the flight attendants handed out drinks after using the lavatory.

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.

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

Very good. Nice plane and we sat in economy plus - bigger seats, more room. They served a meal and snacks, and the meal was an apple stuffed pancake that was very good! The snack for us was a hummus sandwich - also very good. The flight attendants were helpful and nice. They have plenty of movies and shows to watch. My only negative -- they changed our flights around and did not adjust the layovers, so we ended up with a very long and unnecessary layover in Honolulu.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!

The crew was quite good, they came by often with drinks or to collect trash. But what wasn't nice was the flight was over weigh and several people had to be rebooked. I was questioned whether I should have a seat when I was getting to it. The in-flight entertainment kept buffering and interrupting. And the route took the airplane through high winds which caused us a longer flight

Wasn’t on the flight due to Alaska cancellation…also after all the rerouting, I was going to be on a later flight that left SFO at 7:47pm, which meant an almost 6 hour layover. That same Hawaiian flight was delayed for another 2hours.

I had to cancel the flight because with a 3 hour delay for 'unexpected maintenance' in getting to LAX, I couldn't connect to an overseas flight that I had booked on Scandinavian Air.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

Little warm on the plane and delayed for an hour

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.
