Century Agenda Adopted in 2012 
In 2011 SEA had 14 medium- and long-haul international services 
The Century Agenda seeks to double that number to 28 by 2036 
By year end 2016 SEA will have 22 medium- and long-haul
international services 
What gating requirement does that impressive international
growth drive?

Demand Continues to Exceed Capacity

Action Requested 
Authorize a change in the scope, budget and schedule for
the current IAF Phase I: 
- Approve an additional $41M to permit the extension of
the IAF Sterile Corridor to accommodate the two
international widebody gates originally contemplated
as IAF Phase II work. 
- Extend the completion date for IAF Phase I by
approximately five months to permit the construction
of those two additional gates. This would not impact
the scheduled Fall 2019 opening of the current IAF
project.
