SYNOPSIS 
This project is a component of the North Sea-Tac Airport Renovation (NorthSTAR) program to
support Alaska Airlines curb-to-seat vision to improve passenger throughput and circulation,
enhance customer service, improve operational efficiency, allow more efficient use of the north
main terminal checkpoint, passenger circulation/processing to better support future passenger
growth, improve aesthetics, and to maximize openness. The project will reconfigure and expand
the security checkpoint; update passenger check-in and baggage drop off in the north main
terminal, incorporate dynamic variable message and static signage, and make minor curbside
improvements. The existing security checkpoint is space-constrained and has poor air quality
and circulation. There is no ability to expand this checkpoint to meet projected passenger levels
since it is constrained in space between the secure concourse, vertical circulation, and now
vacant airline counters (previously United Airlines) that can be removed to provide space to
expand. The project will  incorporate self-check-in, bag tagging, and baggage drop off
technology for passengers and locate a limited amount of airline counters to accommodate future
growth. Aesthetic upgrades such as modernizing finishes and upgrading flooring as well as 
maximizing openness will be pursued. Alaska Air Group (AAG) plans to implement innovative
and interactive customer service initiatives for its passengers within this space. Sustainable

materials will be utilized to the extent possible. This project was included in the 2014-2018 
capital budget and plan of finance.
BACKGROUND 
The North Main Terminal Improvements Project is one project within the NorthSTAR program.
The current checkpoint is severely space-constrained, consisting of seven irregularly placed 
passenger-screening lanes with no room for expansion to meet the projected AAG passenger
growth. The constrained space also limits flexibility to accommodate queuing requirements
critical to improving passenger throughput.  Further, the checkpoint being situated in the
confined back corridor has created heating, cooling and air quality and flow issues beyond the
capability of the existing 30 year old heating/air-conditioning (HVAC) system.
In addition to the checkpoint expansion, the project will implement improvements to passenger
processing and circulation in the north main terminal ticketing lobby and curbside through the
use of static and dynamic variable message signage and minor curbside improvements. Alaska
Air Group will be implementing innovative and interactive initiatives to enhance customer
service. These initiatives will be consistent with the airline innovation, wayfinding and branding 
activities being incorporated throughout the NorthSTAR program. New technologies for
passenger self-check-in, bag tagging, and baggage drop off will be pursued for use in the
ticketing lobby and promenade/sky bridge level. To accommodate future growth, new airline 
counters will be situated potentially against the ticketing lobby window wall to minimize
disruption of the passenger circulation through the north main terminal. Further, opportunities to
upgrades the terminal appearance/finishes and maximize openness similar to that done in the
south main terminal will be pursued.
PROJECT JUSTIFICATION AND DETAILS 
The inability of the current location and configuration of the north security checkpoint to meet
the projected growth will significantly impact the objectives for the NorthSTAR program. With
the relocation of United Airlines to the southern end of the terminal as part of the Airline
Realignment Project, the ticket counters and adjacent airline support offices are vacant and the
ticketing lobby is significantly underutilized.   The corridor behind the vacated ticket
counters/office space is narrow, requiring an irregular, linear placement of the Transportation
Security Administration (TSA) passenger security checkpoint equipment and associated queuing,
limiting the ability of the Port and TSA to effectively align the checkpoint lanes to improve
efficiency and throughput.  Current projections for passengers utilizing the north security
checkpoint before proceeding to the North Satellite and C and D Concourse forecasts the need
for two additional checkpoint lanes, increasing the number from seven to nine. The constrained
back corridor cannot accommodate further expansion, and other nearby checkpoints are unable
to accommodate the growth. The design of the checkpoint will utilize the latest TSA checkpoint
design standards and guidelines for equipment arrangements and passenger queuing. 
Self-check-in, bag tagging, and baggage drop off technologies will be implemented to provide
efficient processing of passengers, utilizing space in a manner that is convenient to but does not

impair circulation within the ticketing lobby and from the curb and sky bridges accessing the
parking garage. Dynamic variable message and static wayfinding signage will be incorporated 
into the project to improve the passenger experience. Further, a limited number of new airline 
counters will be installed to accommodate future growth. Expanding the existing front window
wall of the terminal similar to the expansion under construction at the south main terminal will
be pursued. Finally, AAG will be implementing customer service innovations and branding
consistent with initiatives currently in development for the North Satellite improvements.
Project Objectives 
Reconfigure and expand the north main terminal passenger security screening
checkpoint to meet projected passenger growth consistent with the NorthSTAR
program projections and TSA design standards and guidelines. 
Maximize efficient passenger processing through implementation of self-check-in, bag
tagging, and baggage drop off technologies. 
Install new airline counters to meet projected airline needs while minimizing impact on
passenger circulation. 
Improve customer experience through implementation of innovative and interactive
wayfinding and airport/airline informational displays and devices. 
Improve the conditioned environment in the north main terminal and maximize energy
efficiency. 
Improve wayfinding through the use of dynamic variable message and static signage. 
Modernize terminal finishes and maximize openness. 
Scope of Work 
Reconfigure and expand the north main terminal checkpoint from seven to nine lanes
and reconfigure the checkpoint queuing. 
Locate and install self-ticketing and baggage drop off kiosks in the north main terminal
and on the promenade/sky bridges. 
Install the appropriate number of new ticket counters to meet future demand, located
potentially along the window wall. 
Upgrade passenger wayfinding to better accommodate passengers arriving from the
curbside, parking garage/sky bridges, rental car buses, and the light rail station. 
Implement innovative and interactive technologies to enhance the customer experience
when approaching and while in the terminal. 
Upgrade the HVAC system in the reconfigured north main terminal to improve the
conditioned environment and energy efficiency.

The design phase will involve multiple phases, which accounts for the extended duration. The
initial preliminary design phase will involve passenger flow modeling and conceptual layout
designs to confirm the passenger security checkpoint configuration and size, and location of self 
check-in, bag drop off, and new airline counters in the ticketing lobby. This effort will better
define the project scope from which a design firm will be procured to further refine the project
scope, schedule and budget before starting the final design.

environmental quality. 
Community Benefits 
The Office of Social Responsibility (OSR) will provide support in determining small business
participation, as described in the small business resolution 3618. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1) - Do Nothing:  The current north security checkpoint is congested and space
constrained with no room for the necessary expansion to meet projected passenger growth. In
addition, the ticketing lobby is significantly underutilized with the relocation of United Airlines
to the south main terminal and the resulting vacant ticket counters and airline support offices.
Maintaining the existing conditions would not meet the intent of the Letter of Understanding
between the Port and AAG, nor meet the program's vision, goals and objectives to enhance
customer experience from curb to seat. This alternative is not recommended. 
Alternative 2)    Expand the North Security Checkpoint:  This option would involve
demolishing the vacant ticket counters and support offices to provide sufficient space to expand
and to the extent possible, reconfigure the checkpoint queuing. This option would not address
the upgrade and reutilization of the ticket lobby, sky bridges and curbside to enhance passenger
circulation, self-check-in, bag tagging,  and baggage drop off  stations, wayfinding and
informational displays, and placement of new airline counters in a manner that maximizes
passenger circulation and throughput.  This option would only partially meet the intent of the
Letter of Understanding between the Port and AAG, and would not fully meet the program's
vision, goals and objectives to enhance customer experience from curb to seat. This alternative
is not recommended. 
Alternative 3)  Reconfigure and expand the north security checkpoint and upgrade the ticketing
lobby circulation and services: This option allows for the reconfiguration and expansion of the
north passenger security checkpoint in a manner that maximizes the queuing and screening
equipment to increase the efficiency of processing passengers to accommodate projected 
passenger levels.  Self-check-in, bag tagging,  and baggage drop technologies can be
implemented to provide efficient processing of passengers, utilizing space in a manner that is
convenient to but does not impair circulation into the lobby from curbside and from the sky
bridges accessing the parking garage. A limited number of new airline counters will be installed
to accommodate future growth. Further, AAG can implement customer service innovations and
branding consistent with initiatives currently in development for the North Satellite
improvements. With the reconfiguration of the north main terminal, HVAC upgrades will be
implemented to improve the conditioned environment and achieve greater energy efficiency.
This alternative fully meets the intent of the Letter of Understanding between the Port and AAG
