A month with two personalities: the first two weeks are a famous dead zone with near-November pricing, then the holiday peak arrives and everything flips.
Where the value sits: Almost anywhere in the first half of the month; city trips after the New Year rush is booked out around you.
The stated catch: From roughly December 15 the same fares become the year's most expensive; the southern hemisphere (Australia, New Zealand, South America beaches) is in full summer peak all month.

Fix only your origin and let the destination be an outcome: open your city's board, and every fare is ranked by how far it sits below what that trip usually costs.
