Airport Profiles: Departure and Arrival Details

Portland International Airport (PDX)

• Location & Layout: Situated approximately 12 miles northeast of downtown Portland along the Columbia River. PDX is celebrated for its accessible terminal design, post-security bypasses, and locally mandated street pricing on all concessions.
• Terminal Navigation: All international flights depart from the main terminal complex. If your itinerary begins with a domestic positioning leg (such as Portland to Seattle or Chicago), departures typically operate out of Concourse B, C, D, or E.
• Ground Transport: Accessible directly via the TriMet MAX Light Rail Red Line, which drops passengers directly at the main baggage claim level. Rideshares and metered taxis utilize designated island pick-up zones just outside the terminal.

Jomo Kenyatta International Airport (NBO)

• Location & Layout: Located in Embakasi, roughly 11 miles southeast of central Nairobi. NBO serves as the premier aviation gateway to East Africa.
• Terminals: International arrivals primarily process through Terminal 1A (servicing Kenya Airways and SkyTeam partners) and Terminal 1E. Domestic safari bush flights frequently depart from Wilson Airport (WIL), located across the city, requiring a cross-town ground transfer.
• Arrival Logistics & Immigration: Travelers must hold an approved electronic Travel Authorisation (eTA) before boarding their flight in the US. Upon arrival, proceed through passport control, collect baggage, and clear customs screening before exiting into the main transport reception area.
• Ground Transport to Nairobi: The modern Nairobi Expressway allows travelers to bypass historic Mombasa Road congestion, linking JKIA to Westlands and the central business district in roughly 20 to 30 minutes. Pre-booked private safari transfers, official yellow-line airport taxis, and major rideshare apps are readily accessible outside the arrivals hall.

Practical Long-Haul Transition Tips (PDX to NBO)

1. Managing the 10-Hour Clock Shift: Portland operates on Pacific Time (UTC-8 / UTC-7), while Nairobi stays on East Africa Time (UTC+3) year-round without daylight saving adjustments. Shift your sleep cycle 1–2 hours earlier for three nights before departure and prioritize direct hydration during transatlantic legs.
2. Connecting to Wilson Airport (WIL): If you are catching an onward bush flight to the Maasai Mara, Samburu, or Amboseli, ensure at least a 3- to 4-hour connection window between your international landing at JKIA and your departure from Wilson Airport to accommodate cross-town transit and baggage retrieval.
3. Currency and Mobile Money: While major hotels and safari lodges accept international credit cards, local daily commerce relies heavily on mobile money (M-Pesa) and Kenyan Shillings (KES). Carry pristine US Dollar banknotes (printed in or after 2013 with no tears or marks) for currency exchange, as older bills are widely rejected throughout East Africa.
4. Health and Prophylaxis: Consult a travel medicine clinic in Portland at least 6 weeks before flying. While Nairobi itself is low-risk for malaria due to its elevation, almost all surrounding national parks require preventive antimalarials. Yellow fever vaccination documentation may be requested if transiting through designated endemic zones.
