Reviews of the top 4 airlines serving from Costa Rica to Seattle
I did not feel secure that the staff knew all that they needed to, especially for securing the seats that I wanted for my next flights. However, they were friendly.

Service is always great with Alaska. Baggage services seems to be delayed in Seattle but Alaska airlines follows up with excellent customer service
Nice planes, Great crew. Ok snacks. One of the better airlines. Ok price.
It sucked. It was so warm the whole flight I had to use a cup of ice to cool me down. It was cramped and it smelled. There were screaming babies.
The people were great, the plugs were European with no adapters, and the snack was seven pretzel rods. The flight entertainment require the Wi-Fi that my browser couldn’t load.
Alaska Airlines is the absolute best. I am so pleased with their service and attention to detail. They are one of the last remaining airlines where you feel like a person rather than a herded animal. Thanks Alaska!
Alaska over booked a flight and we had to scrabble with two young children to try to reach Seattle for our connecting flight.
As always the crew were super polite and friendly, sadly the weather & a minor mechanical issue reduced the quality of the flight, all’s well as it turned out. Still my favorite airline to fly with
Being on time would be a good start. Every flight I had was delayed making it very stressful.
Overall its fine, but I've been lowering my bar for what to expect over the years. What I look forward to most is the crew. Alaska's flight crews are the best. I compare every other airline I fly to yours. Ok, so now lets discuss the plane and amenities: One of the bathroom sinks was inoperable. The crew did the right thing by putting hand sanitizer there. On food - there really isn't any food on these flights unless you pre-buy it and I missed the window, so I ate some garbage in DFW's Terminal E. Let's face it - terminal food in most airports is just junk, so not your fault. The only snack we got on our flight was a bag of salty, cinnamon flavored pretzels. I ate mine, because I was hungry, but really felt like it was a waste of calories. Entertainment options aren't as good as they used to be. I guess Hollywood, Netflix and HBO just aren't creating content like they used to, or we watched everything during COVID and can't be satisfied anymore. I partially finished a number of different shows, ranging from stand up comedians, movies, tv series and foreign films trying to find something. In the end, I could see why nearly everyone around me was brain rotting on Instagram, so I zoned out listening to my favorite playlist and plinked away at email. I see you next month!
Wifi was terrible. I couldn't get any work done on the long flight
The flight was fine. Seats were very comfortable. Attendants were very friendly -
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. :)
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
This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.
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)
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
An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...
Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.
Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time
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.
Flight was delayed because of a bird strike. They had another plane available within 45 minutes.
It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.
The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.
i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.
I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.
Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours
Very smooth for one of the busiest travel days of the year and the crew was great.
Customer service prior to boarding is horrible Communication regarding boarding gates is released at the last minute and the gates are very distant from Customs. Very disappointing
