How to fly from LAX to Seattle for as little as 4,500 miles
Travellers flying between Los Angeles (LAX) and Seattle (SEA) have several options to save money using points and miles. Different loyalty programmes offer varying redemption rates, transfer partners, and booking flexibility. Some deals start as low as 4,500 miles for a one-way ticket in basic economy.
Alaska Airlines offers one of the cheapest redemption options for this route. A one-way economy flight costs just 7,500 Alaska Airlines Atmos Rewards points. These points can be transferred from Citi ThankYou at a 1:1 ratio or from Marriott Bonvoy at a 3:1 ratio, with a 5,000-mile bonus for every 60,000 Marriott points moved.
British Airways Avios also provide a way to book flights on this route. A one-way ticket on American Airlines costs 18,000 Avios. Points can be transferred from American Express Membership Rewards, Chase Ultimate Rewards, or Marriott Bonvoy. However, no direct co-branded credit card with British Airways is currently available for earning Avios on this route. Delta SkyMiles offers another low-cost option, with basic economy fares starting at 4,500 miles plus $5.60 in taxes. But Delta uses dynamic pricing, so the cheapest awards depend on booking far ahead and travelling during off-peak times. SkyMiles can be transferred from American Express Membership Rewards and Marriott Bonvoy. For those using Chase Ultimate Rewards, the Chase Travel Portal allows booking on any airline, not just those with saver awards. The value of points varies depending on the type of Chase card held. This method also earns redeemable miles on the airline flown. To get the best value, experts recommend checking paid flight prices before using points. Cheap cash fares are often available when booked in advance, ensuring points are used wisely.
Travellers on the LAX-SEA route can choose from multiple loyalty programmes to cut costs. Alaska Airlines and Delta provide the lowest redemption rates, while British Airways Avios and Chase’s portal offer flexibility. Checking both cash and points options helps secure the best deal.
