First time flying on Alaska Airlines. Very good experience. Boarded, landed on time, baggage claim was quick just as they guarantee. When returning home, the nicest person at the check in counter helped with our checked luggage tickets and our wine cases, which were free to check (one per passenger) when you joined their rewards program. Will definitely use this airline again!

Boarding was smooth, the crew was kind and friendly, and even though we were in the Saver class, the seats were generous enough for my daughter to nap on me and I had enough room to recline and sleep for our overnight flight. If I had stayed awake I might have quibbled with the lack of a true meal, but the snacks worked for me and when my daughter was hungry (as she did NOT sleep), the crew took care of her. There was room for all of our bags on a very full flight, which was nice. It has been awhile since I haven’t checked a bag, so I had worried.

I got my seat changed last minute so a parent coumd sit with their child wich i found out was a teenager

They offer the only direct flight from Seattle to Pittsburgh.

We flew to Seattle on 7/21, right after the company wide problems the day before. We were delayed 3 hours but understood. We were grateful it wasn’t canceled. As a larger, disabled person, my son booked us in 1st class, row 1. That was fine. My problem occurred while trying to use the restroom. I had to back in and barely had room to move. I started into a silent panic attack where my breathing was affected. I made it back to my seat, shaken. I understand space is limited but something needs to be done. This was on the trip out. The return trip had 4-5 disabled passengers. I watched them struggle. This plane’s restroom was a “little “ bigger. It was a little easier compared to the first plane. That’s my opinion! The crews were fantastic on both flights!

Both legs of the trip were delayed about an hour. Planes were new, liked the WiFi availability and entertainment available. Crew was very good. People were happy and helpful. Liked the pilots - they provided updates throughout the flights. Snacks were underwhelming. Drinks were good! Like the smaller sodas and they actually came through the cabin 2x which was great. In Seattle airport the construction caused much confusion for Alaska. Process of printing own tags, etc was chaotic for people who didn’t check in online prior to arrival which in turn caused issues for those who did. Plus airport gates were too small for the number of people flying.

It was as good as flying can be, which is still very uncomfortable. Clean new aircraft, great crew.

Alaska Airlines fraudulently listed this as a direct flight to Pittsburgh. We landed in Cleveland, waited an hour, then flew to PIT. No one was told about this. When I called and spoke with Alaskan Airways customer care, they were extremely unhelpful and lied about the direct flight. I have my receipt showing a direct flight. I am in the process of working with my credit card because Alaskan Airlines misrepresented the sale/service. I will never do business with Alaskan Airlines again.

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

Flight was a bit turbulent, and there was a delay. Everything else was fine!

Flight was delayed about 50 minutes and completely full. they did the usual demand for people to check carry-ons. they called all groups to board very fast only to stand in the gangway after having boarding passes scanned. Why don't airlines board from the back to front - since they now have assigned seats? our stewardess got drink orders confused, so she just called out "cranberry". etc.,.. I wish they wouldn't serve pretzels snacks with a powdered coating, as it sticks to your hands and they don't have wet wipes. don't want to lick my fingers after hanging out in the terminal for over an hour.

Delayed over 3 hours, extremely rough landing on all four flights. Would not recommend

Boarding, crew and inflight entertainment was great. Could have better food options for a long flight. Paid money and got a seat with extra leg space but was asked to keep my carry on under the seat in front of me which defeats the purpose of buying a extra space seat.

It was great and arrived home a little sooner than expected which is nice.

Multiple delays due to weather in Chicago, but the crew did their best to get flights rescheduled and on to their destination. I felt like the crews handled a frustrating situation very well, kudos to them! I was very glad to not have a cancelled flight.

The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

I flew twice this week on Southwest, was delayed over 2 hours both ways. From Pittsburgh to Chicago it was due to weather but the gate agents, pilot etc were great at updating everyone. Today from Midway to Pittsburgh the plane had come from an international location, kept getting delayed, no information was given until we were delayed for the third time. It was ridiculous, whoever scheduled that plane to fly to Pittsburgh after didn’t consider a lot of things.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The crew was very nice and respectful and everything went well.

Having a direct flight between Pittsburgh and Austin makes traveling so easy.

The main issue was the quantity of the drink. The hostess gave only half cup full of the soft drink. I was thirsty and was expecting full glass like every other time.

The baseline is to have everything happen as expected. That is what happened with the small exception that climate control in the aircraft sss not turned on when boarding started making the aircraft very hot. All in all great experience!

The crew was excellent but the entertainment did not work. The 3mm jack for the headphones was faulty and no sound was available for entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Delayed. Hot. Passenger next to me was so large I couldn’t move.

2+hrs delay without any reason provided and a cramped flight

Originally, I was booked in economy. I paid several hundred additional dollars to upgrade to first class. Then I paid several more hundred dollars to change my flight to a slightly earlier flight. I asked if the changed flight would also seat me in first class, and I was told that it would. When I boarded the plane, however, I was seated in economy. So, I paid $500-600 more than I paid for my original ticket for an upgrade and a changed flight - received the changed flight (which was nice), but did not receive the upgrade. So, I was not completely satisfied.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

I still prefer Delta, but Delta doesn’t fly to State College PA.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

Ok so apparently the new policy on United Airlines is that customers in the main cabin should NEVER be served more than once and besides picking up trash there should NEVER be another interaction with the customer for any reason.

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Wheel Chair Access sucked. I had a guy from Bangaldesh drop me off without taking me to the gate

comfy and spacious seats for premium economy, nice flight attendants. only problem was the wifi did not work, and my entertainment screen was locked in Arabic language and all kids shows with no way of seemingly changing it. but the flight was fine and I arrived with no issues

Although it was a smaller plane, the flight was quick and uneventful.

We left nearly 40 minutes late, which is a long time when you're just seated and waiting. Otherwise, it went well.

Cabin was bone dry, no humidity whatsoever, and pretty warm; and beverage service didn't start for at least an hour. I had to go to the back for water and the FAs tried telling me it was always this way for all Miami flights, which is complete nonsense. Avoid the MAX8 like the plague.

Flight was 2+ hours delayed and they “misplaced” all 3 of our checked-in bags.

Internet is much improved, which is very important to me a s a business traveler. The off boarding of the plane was fantastic. Very quick and very orderly. We had to check our carry-ons before we got on the plane and they were retrieved and available to us very quickly. We left on time and arrived early. All very good things

I always looks forward to the Biscoff cookies and they weren’t offered….

The flight was overbooked. And the gate agent basically said that the flight will not leave unless two people came forward to give up their seats. Offered money. Raised the $$ too. But we were there for a while and flight was delayed. When passengers approached the gate agent asking what would happen if no one volunteered- the answer was flight would be cancelled! Ridiculous! It’s American’s fault for overbooking. The service level is going from Bad to worse it seems.
