My issue is not with Alaska for but with the travel agency. The fact that i can't change my flight online, means that using you as a travel agency is a net negative. I only do it because I am forced to, but I am not happy about it.

My issue is not with Alaska for but with the travel agency. The fact that i can't change my flight online, means that using you as a travel agency is a net negative. I only do it because I am forced to, but I am not happy about it.

The flight was late, almost missed my connecting flight. There was no communication from the crew and when I asked the flight attendant I received no assistance. Terrible flight!!!!

The aisles were very narrow for passing and too long to get to the restrooms. You asked to check carryons at boarding, but the bag was not at the luggage carousels on arrival and no information given as to where to pick them up.

They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

The crew was excellent. We brought our own snacks due to dietary requirements and personal preference. There was an ample beverage selection. The seating was comfortable enough. My only complaint was that there was no announcement, or at least none that we could hear, that our connecting flight was departing from a different terminal. That could been announced by the air crew in flight or before disembarking.

when we arrived crew told us our luggage was at a certain location , waited for nearly an hour after landing and no luggage was there. turned out the luggage was somewhere else far away and no one told us. very incompetent.

5 hr flight with no meal service is just unacceptable. We got pretzels and a drink..

The seating is very small. I have restless legs but the people did everything they could to help me. Unfortunately I asked for a wheelchair between Charleston and Seattle but they didn’t have one for me! The rest of my trip was good.

My flight was cancelled last minute with zero acceptable options and reimbursement. I called Alaska and was told I had to pay for my own flight home so I bought a ticket for $500, I missed work worth $450. I had no babysitter for my child and her father missed work for another $480. I have diabetes and health conditions that require medication and proper diet which was extremely difficult with only $48 of vouchers and not enough medication for the extra 24 hour to 48 hour delays home. I understand things happen but the support Alaska gave wasn’t responsive enough to compensate or reimburse for the inconvenience. It took several hours to get a hotel for the night as Alaskas link was incorrect, vouchers were used and had no more rooms, people were walking the airport 10x to be told their next flights weren’t accurate home. If someone was disabled I don’t know how they even got support.

Awful. My flight ight 443 from Phila was over 30 minutes late and when it arrived.ittook more than 20minutes together toyhegate and 15minutes together to.checkink in. There was insufficient time to get to the terminal and theplaneleft demanding mme inSeattle. Alaska airline custservice wouldnodue anything except book me on a 3:30 pm flight on ov 15. I had to spend almost 16 hours.overnight.in.the terminal I only

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

I would have liked to arrive on time - not 5 hours late!

Board Milian spokesman with pre boarding , not after A group and without my spouse. Total BS, back to Alaska Airlibes I GO. oner 1.2M miles and 900 flights, and every time I fly SWA I regret it, thos will be last time, I only flew SWA but to time requirements fir a Funeral. NEVER AGAIN SWA

Good crew, funny movies, but you need phone ports in the plane and better snacks. :)

Very good. Exactly what I expected. We did have a slight delay.

I think Southwest can offer a whole can of beverage instead of such a small cup

Had a long layover in rainy Chicago. The staff were attentive - my husband needed a wheelchair due to a recent fall and unsteady on his feet. They are wonderful for those of us who need a bit of extra care. My only complaint was discovered upon unpacking our suitcases at home. One (we had 3 carry on size and one just a bit larger) had water damage to everything inside. All the clothing (just happened to be the case with the clean clothes) were wet. I know it was raining, but why would items inside be wet? The paperwork packed in this case was damp with ink running. There were momentos from our 10-day European vacation that I was hoping to scrapbook - but alas, they will be scrapped - too damaged to keep. The boxes of French chocolate were damp on the outside. My expensive camera now has a cracked screen and a Gaudi tea-for-one was cracked - even though it was packed in clothing. I know it happened on this flight as I repacked all four suitcases before leaving New York in the morning. My first unhappy experience with luggage at Southwest.

The a/c wasn’t working very well and it was a very hot flight

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

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

leg space better than expected. two washrooms for one plane isn't enough.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The flight was delayed, but other than that everything was fine.

Flight was fine, but not having WiFi was a major negative

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

Would have thought that they would gas up plane before everyone got on board

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.
