Is booking on Tuesday really cheaper?

That is a myth. Airlines update their inventory constantly. The best time to book is whenever you see a price that fits your budget, regardless of the day of the week.

Should I wait until 24 hours before departure?

Almost never. In the current airline pricing model, prices spike significantly in the final 72 hours. The 'sweet spot' for last-minute deals is usually 7 to 14 days before departure.

Does using Incognito mode help?

No. Airlines do not use cookies to track your search history to increase prices for you specifically. This is a persistent travel myth.

Finding Last-Minute Flight Deals

To find last-minute deals, use Google Flights' 'Explore' feature to see all low-cost options from your departure city for the next 7–14 days. Avoid searching for specific destinations; instead, let the price map dictate where you go.

Use the Google Flights Explore map. Go to Google Flights, enter your departure airport, and leave the destination field empty. Click 'Explore' to see a map of prices for the upcoming weekend or next two weeks.
Set up price tracking alerts. If you have a specific destination in mind, toggle 'Track prices' for your dates. You will get an email notification the moment the airline drops the fare.
Check budget airline sites directly. Use aggregators to find the flight, but always cross-reference the airline's own website. Budget carriers like Southwest, RyanAir, or AirAsia often have 'web-only' last-minute flash sales not listed on aggregators.
Fly midweek. Search for departures on Tuesdays or Wednesdays. Last-minute tickets for Friday or Sunday travel are rarely discounted because they are high-demand business travel days.
