Flights from Newark to Seattle: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Newark to Seattle 
Verified travelerFlew with Alaska AirlinesEWR-SEASep 2024
Buy something in the airport to eat before boarding as its a long flight and the snacks are not enough unless you plan to sleep the whole ride.
KatieFlew with Alaska AirlinesEWR-SEAJun 2024
Alaska Airlines offered free checked bag and personal bag with ticket price which I found to be very reasonable. Of the other airlines I found Alaska Airlines to be most comfortable, have friendly and efficient staff and reasonable pricing. Newark airport is rather easy to navigate given its size. We found Seattle airport to be a bit difficult to navigate, especially when returning a rental. Customers in this instance should allow extra time for the car return, bus to the terminal and navigating through the airport which included several monorails to get to our boarding terminal and through security to the gate. Signage for security was confusing we needed to ask for direction and restaurants were limited and short staffed once through security. As long as you allow for extra time, we found it to be relatively painless.

Paid extra $230 to check frozen fish on arrival to LAX. I was told my bags miss my flight and we’re gonna be on the next flight that comes in two hours later regrettably my family was here to pick me up so I had to drive all the way home to drop them off then turn around and come back if I had waited on Alaska to deliver them they told me that they would be delivered in 4 to 6 hours after 8 AM tomorrow which would’ve caused the fish to spoil stink and be a lost cause they would’ve put about $2500 worth of fish down the drain very unhappy with Alaska Airlines for not getting my baggage here, especially since I had to pay for the extra service

I was very pleased with this trip from Anchorage to Seattle and Seattle to Billings. Wheelchair assistance was rendered and gratefully accepted. Unlike my outbound flights to Seattle I did not have long, painful walks on a bad knee to get to airport gates. My thanks to the Alaska staff.

No issues at all other than the seats. Of all the airlines I've flown on in my life (this was my first with Alaska Airlines), these were significantly the most uncomfortable seats I've had - more so than Spirit Airlines. I'm a relatively young guy and mostly fit but oof, i was aching in muscles I didn't even know I had. Not sure if the seats are standard for the plane (if it even works like that) or if the choice to use cardboard as cushion and 90 degree angle back rests was a decision, but it wouldn't honestly make me think twice about flying with them again. Other than that - perfect flight. It was quick, crew was nice, ride was smooth so all things considered I appreciate the last minute availability offered after a sudden relocation on my part.

Short flight was fine, but no entertainment and bathrooms broken.

All went smoothly. Only one delay departing Seattle of around 30 minutes.

We were in 1st class. Haven’t flown 1st class in over 35 years. This was special trip. 30yr anniversary and family travel. Food was good for airline food. Crew was very attentive.i expected easier movie access. Had to use own device. Second leg with Hawaiian airlines was exceptional in every way.

I paid for a window seat and on both flights I was put in the middle seat. Then on my flight to seattle I had to sit next to a passenger with a cat. I'm allergic to cats. So I sneezed, and had a running nose all flight.

Since the flight was delayed, snacks and water were provided.

Would have been nice if my flight was on time and I didn't miss my connection and had to spend the night in Seattle, losing one night at the VRBO I paid for in Sitka. And, my connecting flight was still at the gate when my flight was taxiing to it's gate. But, it took off. Too bad for me. I really can't believe you even want me to review or comment on my experience.

Upon arrival I was disappointed that the assist I requested to get to the baggage claim wasn't provided. The entire baggage area was not clearly marked and I wanted to store my baggage overnight, that wasn't available. I had to take it on the shuttle to the hotel!
