The move will involve the transfer of the check-in ticket counter, gates, and baggage services from Terminal 2 to Harvey Milk Terminal 1. This strategic decision aims to enhance connectivity with American Airlines and other oneworld member airlines, offering greater convenience for passengers with connecting flights, including those traveling to international destinations. Moreover, the new gates will result in shorter taxi times, quicker access to the runways, and ultimately lead to time savings and reduced fuel consumption.

What the change means to you as a flier;
After investing a staggering $2.3 billion in infrastructure upgrades for Terminal 1, the soon-to-be-unveiled Alaska Airlines Terminal at SFO brings immense benefits to you. The Harvey Milk Terminal 1 boasts a remarkable 60% reduction in energy consumption compared to similar facilities making it among the most sustainable terminals in the US. Notably, it holds the distinction of being the world’s first airport terminal to achieve the prestigious Leadership in Energy and Environmental Design (LEED) v4 Platinum certification, recognizing its outstanding design, construction, and operation as a high-performance structure.
As a passenger, the shift to Terminal 1 will provide a much more enjoyable travel experience. It boasts more spacious boarding areas, better amenities such as restaurants and retail stores, free Wi-Fi, an automated baggage system that speeds up the time it takes to get your suitcase or backpack from check-in to the carousel, and easy access to public transportation networks. Moreover, you can expect plenty of room to work and relax.

Passengers traveling with American Airlines will also benefit from this development as the two airlines share a common terminal (Terminal 1). This will make navigating between different gates more convenient since you will no longer have to clear security multiple times while connecting flights. The same applies for passengers making international connections, allowing them to seamlessly move between connecting flights without having to clear customs and immigration.
We look forward to the Alaska Airlines at SFO Terminal 1 experience, with its improved service and amenities for travelers!
