Common Myths Debunked

Reality: Google is fast and accurate, but often misses budget airlines that Skyscanner catches.

Reality: Mostly false. Airline prices change frequently due to demand, not your cookies. Still, searching in incognito doesn't hurt!

❌ Myth: "Booking directly with airlines is always more expensive"

Reality: Direct bookings are usually the SAME price as third-party sites, with better customer service.
