Alaska is by far the best airline to fly with 😍

I like the new adjustable headrest. Unfortunately 2 crying children were in front of us. But it was the first time and not holding Alaska accountable for that. Alaska always seems to have everything in order professional but comfortable.

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

Flight was cancelled while everyond was on the plane, ready for take off

Flight attendant in front portion of flight was surly. Aisle way too narrow, seats a bit narrow as well. If a large person had been seated next to me they would have been touching me and that’s not acceptable.

Smooth and pleasant all around. I saw extra care taken for people's belongings.

It was ok. Alaska was adequate. Efficient and what I paid for it was fair. The boarding area at the gate was a joke. By the time they get past the C boarding group people all line up impatiently and then it’s chaos. We were boarding early then we sat on the tarmac for 30 minutes. I would of rather sat in the airport.

I do not like the policy of paying up to get a seat assignment.

Landing was so smooth I almost didn’t realize it was happening

Alaska is a great airline. My level of trust with them is very high.

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

It was as expected and I was grateful for the wheel chair help and ease of use.

The charges were ridiculous for an hour flight and the turbulence was very scary.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

Tight seats. Be prepared to sit in the middle if you are in boarding group C.

This was a connecting flight for me and I had already traveled for 7 hours. First, the Pilot didn’t show up and then the gate changed twice, after which the flight was rescheduled for 2 hours later. This made me late and I had to make other transportation arrangements to get home to Astoria another 1 hour & 45 minutes away. This cost me $250 more than it should have. Will not fly southwest again.

Long layover in Chicago. Wish that could have been lessened.

Very good flight. Crew was great. No issues and we even arrived early.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

The crew on this leg continue to be extremely helpful with my wife’s mobility issues. They also came by many many times to ensure we were comfortable and had drink some food.

I liked the cleanness in the bathroom and good crew on board and at boarding gates. There was no Hindi (Bollywood) movies. The entertainment can be improved as it is one of the worst one I saw when I compared it with other airlines. The Mumbai to Amsterdam flight did not have any food for my family which does not contain eggs in it though we have selected “Hindu Asian vegetarian meal”

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

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.

My flight was delayed three hours and then cancelled. The gate agent proceeded to rebook me in a middle seat without telling me and I was placed between two large individuals who did not fit in their own seats and instead took up most of mine. It was an awful experience.

Good and friendly staff. Nicely enjoyed the complimentary drink and snack.

Would have been better if the flight went out as scheduled and we’d have been kept informed. Rescheduling the connecting flight out of Portland was especially difficult.

All was good and they were able to seat my travel companion next to me. Thank you.

It was a great flight and nice experience. Would fly Alaska airlines again!

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

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.

The flight is supposed to be Hawaiian, but it's operated by Alaska. As such, I could not find my reservation on Hawaiian nor Alaska website. I could not check in on line. At the airports, even the kiosk could not find my reservation. I needed to wait in a long line to check in even though I have no bag to check. Good thing I got to the airport early enough.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

The worst flight of my life. Never will I fly frontier again

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.
