Most people assume “earlier = cheaper” — but data tells a different story. Based on FlightAI Research’s analysis of 120 million domestic flight orders in 2024, prices follow a non-linear pattern: 31-45 days ahead is actually the sweet spot, while “early bird” tickets 60+ days out are typically 15-25% more expensive.

Advance Days vs Price

Based on Beijing-Shanghai, Shanghai-Guangzhou, and Shenzhen-Shanghai routes (economy class, tax-inclusive averages):
