When to book
With fewer than daily flights, the best days sell first around Lunar New Year, the summer and late December. Flexible dates help.
Direct vs. one-stop
The nonstop is the most direct option. On days it does not fly, connecting via San Francisco or Los Angeles on one ticket is the usual alternative.
When to call a travel expert
If this trip involves a stopover, a premium cabin, family seating, or anything urgent, a named expert can handle the whole itinerary in one conversation.
