December is one of the busiest months at Ninoy Aquino International Airport (MNL) as Filipino travelers leave for the holidays and visiting tourists arrive. Expect longer check-in, security and immigration lines, and consider booking earlier morning flights to reduce the chance of traffic-related delays from Metro Manila's major areas (Quezon City, Makati, Taguig). Philippine Airlines may operate seasonal nonstops to San Francisco International Airport (SFO), while other carriers offer one-stop connections via Tokyo, Seoul, Taipei, or Hong Kong. For a smoother departure experience, pre-check-in online, print or download boarding passes, pre-book airport transfers, and sign up for airline flight alerts. Look for fare deals early in November and the first half of December; last-minute holiday fares typically spike. Book lounges or fast-track services if you need quicker security and immigration processing.

The best time to fly between Ninoy Aquino International Airport (MNL) and San Francisco International Airport (SFO) in December is early in the month (first two weeks) to avoid peak holiday rates and crowds. If you must travel mid- to late-December, aim for flights on weekdays—Tuesdays and Wednesdays are often less expensive than weekend departures.
