The cheapest day to buy tickets on Expedia, particularly in the USA, tends to be Tuesdays. This trend is largely based on airline pricing strategies, as many carriers announce their weekly sales on Monday evenings, prompting competitors to match prices by Tuesday morning. As a result, travelers often find lower fares available on Tuesdays. Additionally, booking during the middle of the week, specifically on Tuesdays and Wednesdays, can yield better deals compared to weekends when demand typically spikes.

While there’s no one-size-fits-all answer to the best day to buy tickets, focusing on midweek purchases, being flexible with your travel dates, and utilizing fare alerts can enhance your chances of finding cheaper fares on Expedia. Always keep an eye on seasonal trends and events that may affect prices in your desired location. Happy travels!
