Whether it’s the promise of coffee at Pike Place Market, exploring the futuristic Space Needle, or strolling along the waterfront, getting there comfortably sets the tone for your entire trip. But in a city that serves as a hub for both domestic and international flights, the choice of airline can make all the difference. After several flights, extensive research, and honest evaluation, I’ve put together a detailed comparison to help you decide which airline truly deserves your ticket.
The Criteria That Matter
Before diving into specific airlines, it’s essential to clarify what I considered in my comparison:
Comfort & Seating: Legroom, seat width, recline, and overall cabin comfort.
In-Flight Service: Quality of meals, drink options, attentiveness of cabin crew.
Entertainment: Availability of personal screens, Wi-Fi, and content variety.

Extras: Frequent flyer benefits, baggage allowance, and perks.
These factors together determine how enjoyable your flight is, especially for a destination like Seattle, where travel can range from a quick domestic hop to a lengthy international journey.
Domestic Flights to Seattle: Comfort Meets Convenience
For domestic travelers, several airlines dominate routes to Seattle-Tacoma International Airport (SEA). Among them, Alaska Airlines, Delta, and United stand out.
Alaska Airlines
Alaska Airlines has built a reputation for being a West Coast favorite, and it’s easy to see why.

Complimentary snacks and beverages, including a small selection of local craft beers.

Some flights can be slightly pricier than budget alternatives.
Verdict: Alaska Airlines is ideal for travelers who prioritize comfort and a pleasant flying experience. Its West Coast hub makes it particularly convenient for those connecting from other cities on the Pacific.
Delta Airlines
Delta is a reliable choice for both domestic and connecting international flights. It’s generally consistent, with a modern fleet and efficient boarding processes.
