San Francisco International Airport (SFO) is accessible by BART, SamTrans, taxi, ride-share, and airport shuttle services. For early December flights to Tribhuvan International Airport (KTM) plan extra time for holiday traffic—allow 90–120 minutes from downtown during morning peak or holiday surges and consider using BART to Millbrae plus shuttle connections to reduce delays. Book parking or an airport hotel if you have a very early departure to avoid stress.
In December, SFO sees increased passenger volumes due to holiday travel and winter connections; arrive 3 hours before international departures to KTM. Use airline online check-in and mobile boarding passes, enroll in CLEAR or TSA PreCheck to speed security, and check terminal-specific bag drop counters for your carrier. Allow extra time for document checks, especially for visas and COVID-related entry requirements if applicable.
San Francisco International Airport (SFO) serves travelers to San Jose, Oakland, Sacramento, Los Angeles, San Diego and Silicon Valley hubs. These nearby major cities are often included in traveler itineraries connecting through SFO when flying long-haul routes like SFO to KTM. Consider multi-city or open-jaw tickets if you plan to visit other West Coast cities before departure.
There are typically no nonstop flights between San Francisco International Airport (SFO) and Tribhuvan International Airport (KTM); December itineraries usually include one or two connections via hubs such as Doha (DOH), Dubai (DXB), Delhi (DEL), or Istanbul (IST). When booking in December, check connection times carefully—winter schedules and higher holiday load can affect availability—book earlier to secure preferred routings and seat classes.
San Francisco usually has mild winter weather, but December can bring rain and coastal fog that may cause flight delays or ground holds; however, significant cancellations are less common than at snow-prone hubs. Monitor airline alerts, sign up for flight status notifications, and build buffer time into connections, especially if routing through inland or mountain hubs that can be snow-affected en route to KTM.
Most airline and third-party lounges at San Francisco International Airport (SFO) operate with normal winter schedules in December, but hours may be adjusted on holidays; check lounge access rules with your airline or credit card program. COVID-19 policies have relaxed in many regions; still, verify current testing/vaccination/entry requirements for Nepal and any transit countries before travel and keep digital copies of necessary documents.
Arriving at Tribhuvan International Airport (KTM) in December from San Francisco International Airport (SFO) offers crisp air and some of the season's best mountain views, making Kathmandu a favorite winter gateway for trekkers and culture travelers. Expect streamlined immigration but increased visitor volume; using e-visa resources and having local currency ready speeds arrival formalities. Domestic flights to Pokhara may have limited frequencies—book early—and arrange airport transfers to central Kathmandu or book an overnight in Thamel to acclimatize before high-altitude travel. CTA: Arrange your KTM airport transfer or compare domestic flight schedules now for December.
Arrivals at Tribhuvan International Airport (KTM) in December experience cool, dry weather and generally good visibility—ideal for mountain views on approach, though mornings can be hazy in the Kathmandu Valley. Expect relatively compact passport control and baggage reclaim areas; allow 60–90 minutes to clear immigration and customs, and pre-arrange airport transfers to Kathmandu city or nearby destinations like Patan and Bhaktapur.
Most nationalities are eligible for a tourist visa on arrival at Tribhuvan International Airport (KTM), but requirements and fees can change—apply online for a visa-on-arrival form or check Nepal's Department of Immigration before travel. In December, peak tourist months for trekking mean extra visa queue times; having completed forms and exact fees in local currency will speed processing.
Tribhuvan International Airport (KTM) is the gateway to Kathmandu city and provides access to Pokhara, Lumbini, Chitwan National Park, Bhaktapur, Patan (Lalitpur), and the broader Himalayan trekking regions. December is popular for lower-elevation treks and cultural tours; book domestic flights to Pokhara early because winter schedules can be limited on windier days.
December brings stable skies and colder temperatures with limited rainfall, which generally improves visibility for domestic flights, though occasional valley fog or low clouds can delay early morning flights. If you have a same-day connection onward to Pokhara or Lukla, include buffer time or consider overnighting in Kathmandu to avoid missed connections due to weather shifts.
From Tribhuvan International Airport (KTM) you can take metered taxis (approx. USD 10–15), pre-booked airport transfer services, or private cars to Thamel and Durbar Marg areas; ride-share availability is limited. December pricing can be higher during peak tourist weeks—confirm fares before boarding and consider arranging transfers through your hotel for fixed rates and support with luggage and winter layering.
Baggage allowances are set by your international carrier, but Tribhuvan International Airport (KTM) enforces customs declarations for high-value goods and agricultural items; declare electronics or cash above permitted limits. In December, trekkers often carry specialized gear—check airline sports equipment policies for checked baggage and consider shipping bulky items ahead to Kathmandu to avoid overweight charges.
December in Kathmandu features winter cultural activities, Christmas and New Year events in hotels and restaurants, and increased trekking departures to lower-elevation trails. While major Nepali festivals like Dashain and Tihar occur earlier in the year, December offers holiday markets, cultural performances in Patan and Bhaktapur, and quieter pilgrimage visits to Lumbini. Book festival-related tours and special dinners early in December to avoid sold-out events during holiday weeks.
The best time to fly from San Francisco International Airport (SFO) to Tribhuvan International Airport (KTM) in December is early-to-mid December (first three weeks) to capture clear mountain views and avoid late-December holiday price surges. Midweek departures (Tuesday–Thursday) often yield the lowest fares, and flights that arrive in Kathmandu during daylight hours maximize mountain visibility on approach. If you need holiday travel, book far in advance and prioritize refundable or flexible fare classes.
There are typically no direct flights between San Francisco International Airport (SFO) and Tribhuvan International Airport (KTM); most December journeys require connections. Choosing a connecting hub affects total travel time and comfort: Doha (DOH) and Dubai (DXB) offer premium lounges and smoother long-haul connections, while Delhi (DEL) often provides the shortest total travel time but may require visa-on-arrival or re-check considerations. For December travel, prioritize reliable connection times and allow longer layovers to protect against weather-related delays in Nepal.
Qatar Airways (SFO–DOH–KTM): strong business class, reliable connections, and frequent schedules; ideal if you value lie-flat seats and lounge access. Emirates (SFO–DXB–KTM via partner): excellent inflight service and global network but often longer total journey times. Turkish Airlines (SFO–IST–KTM): competitive pricing and a pleasant transfer experience at Istanbul Airport. Air India or Star Alliance partners (SFO–DEL–KTM): often shortest total time to Kathmandu but watch visa/transit formalities. For December, compare total travel time, baggage policies, and included amenities; book refundable or change-flexible fares during peak holiday weeks.
Pack warm layers, a good down jacket, and sun protection—December days can be sunny and cold, with chilly nights in Kathmandu and surrounding hills. Hydration and gradual altitude acclimatization are crucial if heading to higher elevations; schedule rest days in Pokhara or Kathmandu before pushing to higher treks. Carry essential medications, a basic first aid kit, and travel insurance that covers mountain rescue or trip interruption. Finally, check and reconfirm domestic flight schedules within Nepal 24–48 hours prior to departure as winter operating hours can change with weather. CTA: Prepare your packing list and purchase travel insurance before your December departure from SFO to KTM.
Typical SFO to KTM itineraries in December range 18–30+ hours including layovers. Example schedules: SFO–DOH (Qatar) overnight, DOH–KTM next-day arrival (total ~20–24 hours); SFO–DXB (Emirates) then DXB–KTM (total ~22–28 hours); SFO–DEL (Air India) then DEL–KTM (total ~18–22 hours). Allow at least 2–3 hours for international-to-international transfers and 3–4 hours if you must clear immigration or re-check luggage in a transit hub. For domestic onward connections within Nepal (e.g., Pokhara), secure a minimum 4–6 hour buffer to accommodate weather-related schedule changes in December.
To secure cheap flights from San Francisco International Airport (SFO) to Tribhuvan International Airport (KTM) in December, book 6–10 weeks ahead and search multi-stop combos via Doha (DOH), Dubai (DXB), or Delhi (DEL). Use fare-aggregators with flexible date grids, enable price drop alerts, and consider flying midweek or departing in early December instead of peak holiday weeks. Look for bundled fares that include checked baggage when connecting across carriers to avoid surprise fees. If you can be flexible with routing and accept a longer layover, you can often reduce fares substantially. CTA: Start a fare alert for SFO to KTM December and compare multi-carrier itineraries now.
