i canceled my flight from SEA to SFO, SNA to SEA and received full refund from Alaska Airlines. i am pleased with the customer service.

i canceled my return flight package with Alaska Airlines. Customer Service was excellent and assisted me to cancelled both of our reservations and returned the payment in full. that is excellent service and understanding and empathy of the customers' needs. i like Alaska Airlines and recommend AS to everyone.

Representatives both at the gate and on the plane have zero interest in helping you! It’s really unfortunate…

I was in economy class and there was plenty of leg room. New interior which was nice and they served various kinds of chips and sodas on the red eye. You couldn't get a bottle of water but they instead served it in a medium paper cup from a reinforced structured paper container, environmental friendly.

Great experience, staff and crew were very professional, friendly and helpful!

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

Alaska used to be a top notch airline. With it's growth it is now in line with the big airlines. Not bad, not great.

Overall it was fine, however one of my two checked bags did not arrive and I was told it was left in Palm Springs. I don't understand how one of the two bags made it through fine but the other got lost .

The seats are very small. I’m 5’ 3”, so don’t think I should notice. The food selection was non existent and very disappointing. 5 hour flight plus TSA, etc. I would have appreciated a small salad, crudités. Something fresher not just chips.

Was notified the departure would be late. Later on it was suddenly on time. Traffic by LAX was horrendous, and I missed the flight.

Avoid at all costs. My wife had to stay back on a connecting flight as her parents flight was delayed. 10 days later on the way back they cancelled all our flights. We had to rebook all four of us on the next days flight.

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

Horrible. No TV or any type of entertainment on board. Passwnger listening to/watching stuff on their own phone with no headphones making it noise and uncomfortable for everyone else, little/tiny food portions, old seats, useless wifi (cant access anything). Horrible exlerience especially it was a lomg distance flight with kids.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

Some of the Air hostesses are not that friendly. Need improvement

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

horrible service, food was an embarrassment, no charging for cellphones, stay away

Great experience with a crew always thinking in the passenger

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

we did a return flight from Paris CDG to SFO. This trip was much better than the departing flight SFO to CDG. The food was better quality, the crew was nicer, and the interior of the plane seemed cleaner.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

We got to get extended leg room in Econ plus that was great. It was nice having our own dietary needs met with our meals, and the connecting flights had it as well. Only negative were the seats my bottom was/is really sore after a ten plus hour flight. Those seats are horrible, understandable for as many people use them. So we are going to purchase a gel seat pad.

Flight to Japan was was better across the board than the return to USA. Entertainment: Movie selection was old and not to my liking. Way too many woke choices. Not enough selections for sports or drama. Service: some of the crew were great. Not all. I paid for business class. a premium. Some of the crew thought they 'had' t do there job instead of wanting to serve and be polite. Food: Way to Japan was good. Way back to USA bad. Boarding: Wat out did not offer Business only; had to go thru general. If you pay for business, you should get business perks. Suggest you look for other than United for travel to Asia

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

The head flight attendant made the trip excellent. He was very accommodating.

The economy seats on the 777 was not as cramped as I had feared, but the food was terrible.

Terrible experience! delay 2 time and say i dont have ticket

I had a great experience flying with JetBlue and would always choose JetBlue over the other airlines. I am also very bummed that they will discontinue flying to Belize very soon. SAD

We were delayed and had to circle due to weather and had to divert for fuel. While I understand that you can’t control the weather I would have appreciated knowing that the crew wasn’t going to run out of hours and then having to spend the night in the Raleigh airport.

Messy plane that was falling apart Small screens that didn't work

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

They forced me to check my hand luggage at the gate.

I specifically choose not to check bags to ensure I can proceed directly to ground transportation upon arrival. However, due to a recurring lack of cabin space, I was again forced to gate-check my rolling luggage after going through my luggage to take out electronics and batteries. This practice unilaterally changes the service agreement made at the time of purchase. JetBlue needs to find a better way to manage overhead space that honors the carry-on baggage allowance.

Still hasn’t left. Why are you asking how it was?

Flight was good wish there were more snacks options for such a long flight but stewardesses were very pleasant as was flight crew.

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.

The flight attendant smashed her beverage cart into my knee, causing significant amount of pain. The seats were extremely uncomfortable. No food or drink is offered unless you want to pay the ridiculous prices for it. The schedule of flying in the overnight hours is also very uncomfortable.

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

We waited for one hour to deboard the plane after landing. That could be better

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!
