How can I buy plane tickets cheaper?

The main thing is to buy tickets 2 - 3 months before your flight, when airlines put out their cheapest fares. If you need to fly urgently, there's basically no chance of getting a discount, but if you have time to spare, you can snag a good price. Check prices on different days of the week - often Tuesday or Wednesday is cheaper than weekends.

Use aggregators like Skyscanner, Aviasales, or Kayak to compare prices across all airlines at once. You can set up price drop alerts for your route - when a cheap ticket shows up, you'll get a notification right away. Sometimes it's cheaper to fly with a connection than a direct flight, so don't skip those options when you're searching.

One more tip: clear your browser cookies before searching or search in a private window. Some sites can raise prices if they see you've already looked at that route. And if you fly often, join an airline's loyalty program - bonus miles sometimes get you a discount or even a free ticket.
