No healthy food choices. There was no in flight entertainment .

The check-in crew for Alaska was rude, unhelpful, and the opposite of customer-centric. We arrived 50 minutes before our flight and were told it was too late to check baggage. When I asked what the cutoff was, the agent started speaking in codes “D50” and yelling to their manager who also spoke in codes. They then tried to speak to me using these codes and all I wanted to know was the time of the cutoff, which they would not — or could not — articulate. They booked me and my family on the next flight while smirking.

Generally Good. Outbound flight was marred by a continuously s creaming baby. Fortunately the flight was only 90 mins long it would be nice if people traveling with small childres could be centered in one part of the plane. Also, you need to adapt your servey to include a "not applicable " option for things like food and entertainment, which are not offered on shorter flights. I fily Alaska by choice as given all the cirumstances, I fel\el you do a good job.

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.

I had to run from the end of terminal one to the end of terminal two to make the connecting flight....probably a kilometer. No electric carts were available. I'm 76 and literally had to run to make the connection at the last minute. The connecting time was absolutely unrealistic. When Last Call was announced, I tried to get other Copa gate staff to call Gate 221 to let them know I was on my way, but they said no. I came within 1 minute of missing the flight.

Boarding was confusing from staff telling going to preboard and than to group 1 Airplane was not cooling at the beginning

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

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

Seats were awful. Media should have been included for such a long flight.

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.

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

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

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

Flew steerage class. Short on leg room unless you pay more. No window unless you pay more. Etc. United is trying to squeeze every cent from you. It doesn’t make for any loyalty.

Outstanding service, great food, friendly & efficient crew, safe & comfortable flight

Staff were not attentive, wifi did not work, cut my head in the bathroom due to the position of the soap on the sink, had blood running down my face, told staff, they had no expression no sympathy, didn't even say "sorry", they said "oh we will have a look at that" about 10 mins later the purser brought me a bandaid, still no sorry.... Shocking

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

All airline travel outside of First or Business class is an ordeal to be endured. This trip was ok, small o, small k.

TV was broken and could not shut it off. The flicking was bother me and gave me a headache. The WiFi wouldn’t work correctly, I was able to text but not search the web or surf social media. The plane itself had a lot of wear and tear it is due for an update.

JetBlue not only has the most comfortable planes, but also used to have the best customer service. Lorie Wright, the lady at the gate was very rude not only to me, but to other passengers as well. Her colleague, the gentleman was also not very friendly. They both were acting like they were doing passengers a favor. The crew on board was very nice.

Flight was on time and smooth. Customer service was decent

Jetblue provided a very good service during the flight, the plane in a very good condition, the crew is professional, everything was on time. That's it!

The space between seat rows seemed to be larger than other airlines. I didn’t check their food or entertainment since I slept most of the way. They do seem to have a lot of options for purchase though.

Boarding was extremely slow and disorganized. Onboard crew was unfriendly.

Kayak sucked. You gave me a confirmation number that was not useable by the jet blue system. Nor did you send any check in emails. I’ll not be using your site again. Nice work.

Given us a free miles or free flight for waiting for 9 hours I didn’t get home till 5am in the morning and I was supposed to be home at 9:30 touch down.

Easy experience even with the outbound flight being delayed. The seating and space was comfortable and the crew seemed very nice and helpful.

The employees at the gate were not communicating, they preferred to give the upgrade to pilots and not to the elite passengers Every flight I more disappointing, clients shooed be priority instead of other employees even if they are pilots, there was plenty room for pilots in economy

Seating was tight. Seats don't recline. Initial flight was cancelled. Lost two days of vacation.

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.

I upgraded to businesses class. Because of that the flight was comfortable.

Boarding was late due to the company’s that cleaned the aircraft (very poorly done) and the catering company. The entertainment system was not working for this six hour flight, uncomfortable seats in business (barely any cushion or recline). The airline staff is very good but the planes are horrible and not well maintained.

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

I couldnt recline the seat. Other than that crew was very attentive and helpful. Thsnk you

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

Horrible experience. Flight cancelled. Arrived at destination 12 hs later. No one gave us an answer or any information. Very very poor service. We won’t ever travel again with Avianca
