KAYAK’s top tips for finding a cheap flight from Seattle to Salt Lake City

  • Looking for a cheap flight? 25% of our users found flights on this route for C$ 196 or less one-way and C$ 195 or less round-trip.
  • Seattle Tacoma International Airport (SEA) is relatively busy compared to other regional airports. As a result, long security lines are often the norm here. You should ensure that you get to the airport at least 3h before your flight is scheduled for departure to have enough time to go through the lines without missing your flight.
  • Seattle Tacoma International Airport is a hub for Delta Air Lines. As a result, the airline has more flights out of this airport than any other airline. Therefore, consider booking with them to get more options and potentially lower ticket prices.
  • While SEA Airport offers airport parking to travelers who come to the airport with their cars, make sure you compare the prices at the airport with offsite parking lots. In most cases, the offsite parking lots charge almost half the price charged by the parking lots inside the airports.
  • To get wheelchair assistance at Salt Lake City International Airport (SLC), inform your airline that you will require one either during booking or at least 48h before your flight is scheduled for departure. This gives them enough time to organize with the officials at the airport to ensure you get your wheelchair upon arrival.
  • If you’re traveling with your pet or a service animal, Salt Lake City Airport has two animal relief areas on Concourse A and B. They are located near Gates A9 and B20 respectively.

We had to take the train to our next gate but had time to eat a meal. When to our next gate and asked employee about gate and got informed that gate had been changed so back on train to next gate. So thankful she was there and informed us of gate change. Because of the issue the boarding was slow but employees were there and busy helping all and keeping it organized.

So thankful she was there and informed us of gate change. Because of the issue the boarding was slow but employees were there and busy helping all and keeping it organized.

Very pleasant and the flight felt like it went by quick

All flight entertainment is from your own device and there was an $8 charge to connect. also 1 drink and a small bag of pretzels was all that was given to us. other that that the seats were good and the flight itself was as expected.

It is very bad they do not give you money back

They lost our bag and it took them days to find it. Terrible communication and lots of lies about where it was. Their system hasn’t merged with Hawaiian yet they route people on shared flights with Hawaiian, creating an administrative nightmare.

Major flight delays, it was a 1.5-hour delay. The gate kept changing about 3 times in Seattle. very hectic and chaotic.

More leg room in back seats. Can you require people to smell good on planes? ha ha Staff was great! Plane was comfortable. I enjoyed the movies and TV. Smooth take off and landing.

The only problem was the time delay. Kudos to the counter agent in Seattle. Very helpful and gracious.

This flight was how a flight should be. The flight from Hawaii to Seattle was terrible

Quick and easy check-in. Love how technology has helped speed up the flying process. Smooth flight to a Seattle and back. 10/10

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Great list of movies, seat was generally comfortable, but not much shoulder room. The fresh baked cookie mostly made up for the lack of variety with the meals, which were all tomato based.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Everything was great. Great service, excellent communication, and early arrival

Very dissatisfied with the fact that I had upgraded to first class for the second part of my trip only to find out that the lounge was still not available to me, as well as not having any food or drink service on the flight due to weather, so I lost out more than what I paid for.

The woman in seat 1A was allowed to bring a dachshund dog onboard. It smelled terrible and the odor wafted throughout the first class cabin. This was clearly not a service dog and should be prohibited. I paid for the highest class of service, and this was a disservice. Why is Delta allowing this? I may reconsider my future flight choices.

Coach seating is debilitating, neither my husband or I can walk the following day

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

I never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.

The Boarding process in Denver was chaotic, and since the line was so long, we were lined up very far from the gate. If there were any announcements from the gate staff, we didn't hear them. The flight attendants were spectacular. The only negative part of the flight was sitting by a 2 1/2 year old who was unruly and unfortunately had parents that matched his behaviors. Also, the restaurants in Denver on the E concourse, they didn't have food (passengers could only order 1 item on the entire menu) or the restaurants had 12-14 people waiting for orders to be prepared and another 6 people waiting to order. If you have a layover in Denver and need to grab food, be prepared to visit the shops with pre-packaged sandwiches, or you can visit another concourse but it may take a while to transit throughout the airport.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.
