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

Insights shared by verified travelers who flew the route from Newark to Seattle 
Verified travelerFlew with Alaska Airlines-Sep 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 Airlines-Jun 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.
