Insights shared by verified travelers who flew the route from O'Hare Intl to Seattle 
PaulFlew with Alaska AirlinesApr 2024
The flight is long, at over four hours. I would try to get a window or aisle seat to be more comfortable. I would check with other airlines that allow you to choose your seat even if you are in the economy section. I would bring your own food on the plane as the service was sometimes sketchy.
Verified travelerFlew with Alaska AirlinesApr 2024
If you miss your flight ask any alaska agent to how and where to rebook the flight.

Signage for hotel shuttles at O’Hare is poor. Restrooms were surprisingly clean. In winter especially, there are going to be delays.

Airline reviews

The flight itself went well, except it left 1.5 hours late, and about 10 of us missed our Alaska Airlines connection by minutes; they wouldn't hold the plane, even though our arrival delay was caused by Alaska. No gluten-free options among the snacks; you had to order meals separately, but there was no consideration for food sensitivities. NO TELEVISION on a flight from Washington, DC to Seattle or from Seattle to Anchorage. I didn't know that ANY airlines offering cross-country flights didn't have screens for entertainment. This alone is a "never again" for me.

This alone is a "never again" for me.

I have to eat gluten-free due to celiac disease, but so far no Alaska Air flight has offered a gluten-free option for the snack given out with free drinks. It seems like that wouldn't be too hard to do.

I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

Full flight where I had another passenger sitting in middle seat who said that he had lost 250 lbs from 500. The stewardess on exiting the flight advise me that I was going to receive a refund. I thought she was talking about another passenger. The stewardess saw that to make him comfortable I had lifted the armrest and flew for 5 hours to Seattle from Reagan DCA with a portion of his body on my seat. I survived. I flight to remember!!!!

the flight was delayed almost 3 hours and not one time was we told that it was delayed or why. I had asked one of the crew members why it was delayed, 20 minutes after the flight was supposed to take off, and was told that they had no idea what was going on and that they had not been told anything. this is FRIGHTENING!!!! No excuse!!

Flights were on time. Check in was fine. Crew members were pleasant.

I would have liked it to have been easier to order food for the flight. My son was not happy with the snack pack I bought him and it was a very long flight for a little boy to go without food.

Ground staff at LAX was very helpful. The Alaska lounge food and service is better than most airport lounges. I think the Staff are well trained polite and actually seem happy to work there. Great service Thanks 🙏 Jjk

The flight was very very delayed and arrived much later than planned. There was no communication about why or when our arrival would be. I would expect better and open communication about the flight but there was none. Also just pretzels? How disappointing.

I got to my destination but no comforts no snacks nothing. Like herding cows!!

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

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...

I’ve had a couple flights this week on United that were delayed by an hour or more

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

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.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

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.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

It was nice! There was a very unhappy child in front of us and the flight attendant did a great job calming the child. I was impressed.

The plane was not on time for boarding or departure or arrivals.

EVERYTHING WAS WONDERFUL HOSPITALITY THE HELP.THE SEATING FRIENDLY ALWAYS HAVE A GOOD RIDE NOT ONE BAD EXPERIENCE WITH THEM

This was the smoothest flight I have had in awhile. I was also offered an exit row seat for a great upgrade cost and was able to sleep almost thr whole flight due to comfort and a smooth flight. We left on time and arrived on time.

No food not even water offered unless you buy it and no usb in the seat but other than that everything was good

Flight expected to leave at 6:40 pm ended leaving at 8:00 am the following day. I slept in a cold airport. Never again Spirit for me…

This was the return leg of my journey with Spirit Airlines. Despite its reputation, I found no issues as it got me from point A to B safely and without delay, especially with no mechanical delays, which is fantastic in my book! The staff, from ground crew to cabin crew, were all pleasant and hassle-free. The flight was smooth from takeoff to landing. I have absolutely no complaints about this no-frills airline!

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

My flight was cancelled!!! I had to spend 200.00 on another flight!!

The flight attendants were very personable, extremely friendly, and had a very good feeling of the energy around them not to mention they’re very funny and engaging. What made up for the discomfort of the seats and the fact that the plane sat for a long time on the Turmac. Not sure if the pilot was new, but the landing was very rough sort of like I was at a magic mountain theme park ride that was built in 1959
