What affects the price

Flight prices shift based on a few key factors. How far ahead you book is usually the biggest one, as seats tend to fill up and get more expensive as the departure date nears. Choosing mid-week travel instead of weekends can often save you money, and flying during off-peak hours helps too. Demand is a major driver, so big holidays or local events can push costs higher.
