📅 When to book — Wellington in December

Travel writers usually only tell you when to go. Here's when to book flights and lodging for the best mix of price and availability, based on December's tier (Shoulder) and Wellington's popularity.

✈ Flights — lead time
6-10 weeks
Sweet spot for value. Major fare-sales (US: Black Friday, EU: post-Easter) hit hardest in shoulder months for shoulder travel.
🏨 Lodging — lead time
4-8 weeks
Lots of selection. Look for shoulder-season packages — many hotels add value (free breakfast, spa credit) to fill rooms.
⚠ Christmas / New Year travel is a global premium-pricing event — many destinations 30-50% above normal. Book 4+ months ahead if your dates are Dec 20 - Jan 2.
