The internet is full of airfare myths — 'book in incognito mode', 'buy exactly on Tuesday at midnight', 'last-minute is always cheaper'. Most of this advice is either outdated or was never true at all. Let's go through the most common airfare myths and see what actually lowers the price of a flight ticket.
Myth 1: incognito mode lowers the price
A widespread belief says airlines raise prices based on your cookies, and that browsing in incognito mode reveals a cheaper fare. In real-world tests the price difference between incognito and a normal session is barely visible — prices depend mainly on seat availability and demand, not on your cookies.
Searching in incognito won't hurt, but it won't lower the price either. Don't waste time on this trick.
Myth 2: there is a 'perfect day' to buy
An old myth claims tickets are cheapest on Tuesday nights. In reality there is no single magic day or hour — prices change several times a day based on algorithms. What really matters is how far ahead you book, not which day of the week.
A more useful rule is different: flying on a Tuesday, Wednesday or Saturday is usually cheaper than Friday or Sunday. Details are in our guide on when to buy tickets.
Myth 3: last-minute tickets are always cheap
Airlines once discounted leftover seats just before departure. Today it's the opposite — last-minute prices are usually high, because an urgent passenger has no alternative. Rare exceptions exist, but this is not a strategy.
If you do have to buy late, see our last-minute flights tips. For reliable savings, planning ahead is better.
Don't wait for the price to 'drop' before departure — on international flights the fare usually rises, not falls, as the date approaches.
Myth 4: one website always shows the cheapest fare
No single site covers every airline and fare. Prices differ between metasearch engines, the airline's own website and agents. That's why it's better to compare several sources and use a price calendar that shows the whole month on one screen.
What actually works
- Book early — 2-4 months ahead is optimal for international flights
- Be flexible with dates — flexible-date savings are often 30-50%
- Turn on price-drop alerts for your favorite routes
- Read our 10 tips for cheap tickets and about error fares
- Use the Travel365 price calendar — the green days are the cheapest
