Here’s how to get the lowest possible price on your holiday flights, according to five years of aggregated Google Flights data. 👇
✈️ Connecting flights can also be a big money saver. Nonstop tickets are 20% more expensive on average.
✈️ When you travel is key for saving: Departing on a Monday and returning on a Tuesday or Wednesday saves about 14% over weekend flights (and up to 20% domestically versus Sunday).
✈️ Wednesday beat Tuesday as the absolute cheapest day to book a flight, but the difference is negligible — buying a ticket on a Wednesday only saves you about 1.4% compared to Sunday, the most expensive day.
