No. There's no solid evidence that airlines raise prices because you searched before. Fares change constantly from demand and seat inventory, not your browser cookies. Incognito doesn't hurt, but it won't lower the price — comparing dates and airports will.
This is the most persistent airfare myth. The idea is that airlines track your searches and jack up the price to pressure you. In practice, fares move because of demand, remaining seats in each fare bucket, competitor pricing and time to departure — all of which change hour to hour regardless of your browser.
When a price looks higher on your second search, it’s almost always because a cheaper fare class sold out or the airline repriced, not because a cookie tagged you.
What actually lowers the price:
- Flexible dates (use the calendar/grid view).
- Alternative airports (compare all airports in the metro).
- Booking in the typical window for the route, not the last three weeks.
- Setting a price alert and buying when it hits a target you decided in advance.
Incognito is harmless and clears any stored search state, so use it if it gives you peace of mind — just don’t expect it to save money on its own.
