ACTION ITEM                   Date of Meeting     January 9, 2018 
DATE:    December 31, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Michael Ehl, Director Airport Operations 
Wayne Grotheer, Director Aviation Project Management Group 
SUBJECT:  Zone 3 Common Use Ticket Counter Conversion Project (CIP #C800925) 
Amount of this request:          $1,650,000 
Total estimated project cost:       $1,700,000 
ACTION REQUESTED 
Request a single Commission authorization for the Executive Director to: (1) proceed with
design and construction of the Zone 3 Common Use Ticket Counter project at Seattle-Tacoma
International Airport; (2) execute a contract to purchase common use equipment; and (3) use
Port crews to complete the project. This single authorization is for a total cost of $1,700,000. 
EXECUTIVE SUMMARY 
This project responds to the continued growth in Airport traffic and airline operations. It
improves the efficiency and flexibility of the ticket lobby, and thus improves the passenger
experience at the Airport. This project is necessary to provide additional common use ticket
counters for new airline entrants that have announced the start of service to Seattle beginning
the summer of 2018. There is currently not enough capacity at the current common use ticket
counters to accommodate these new airlines as these counters are fully subscribed at peak
times. 
The project adds common use ticketing capacity in the Zone 3 Ticket Lobby between Delta Air
Lines and Southwest Airlines creating 10 new common use ticket counter positions. It also adds
8 Common Use Self Service (CUSS) kiosks in the lobby area. Zone 3 is located adjacent to the
passenger security checkpoint that provides the most direct access to international departure
gates. Virgin America, Inc., through the merger with Alaska Airlines, will be vacating the space
in April 2018. 
This single authorization request will allow the project team to proceed quickly as this project
has been deemed a "hot project." Airline operations are impacted by the current lack of ticket
counter capacity that this project will address.

COMMISSION AGENDA  Action Item No. _6c___                     Page 3 of 4 
Meeting Date: January 9, 2018 
Cons: 
(1)   This option does not provide the common use capacity needed to support new
entrant carriers. 
This is not the recommended alternative. 
Alternative 2  Replicate the adjacent Delta Air Lines flow-through ticket counter "islands" by
building out a third check-in island as a Port sponsored capital project using the vacated Virgin
America ticket counters along with the next door vacant former airline ticket office space to
create 17 flow-through passenger check-in positions (8 common use positions, 9 common use
kiosks). 
Cost Implications: $4,300,000 
Pros: 
(1)   Additional common use check-in counters for new entrants would be established. 
(2)   Passenger queueing and circulation in Zone 3 would see improvement. 
Cons: 
(1)   This alternative will not meet the timeline required for new entrants in summer of
2018. 
(2)   This alternative would cost more than Alternative 3. 
This is not the recommended alternative. 
Alternative 3 Convert Virgin America's existing check-in counters to 10 common use positions.
Purchase and install 8 CUSS kiosks. 
Cost Implications: $1,700,000 
Pros: 
(1)   Allows flexibility with 10 common use positions which can be configured to meet
airline needs on-demand. 
(2)   Can be constructed to meet summer deadline for new entrant carriers. 
Cons: 
(1)   Location of construction area will have some impact on Delta operations; will require
coordination with Delta to mitigate impacts. 
This is the recommended alternative.
