As the holiday season approaches, many individuals are focused on finding affordable travel options. In the United States, searches for “cheapest airline tickets” increased by over 240% between April and August of this year. During this period, the most frequently asked questions about air travel were “When is the best time to book a flight?” and “How can I find cheap flights?”

To address these inquiries and others, the Google Flights team analyzed airfare data spanning five years, seeking dependable patterns to assist travelers in their quest. Below are the findings we discovered to assist you in your journey.

In the past, it has been more cost-effective to travel during the week rather than on weekends, particularly on Sundays. On average, flights that depart on Mondays, Tuesdays, or Wednesdays have been 12% cheaper than those departing on weekends. If we consider only domestic flights, potential savings can increase to 20%.

Nonstop Flights vs. Flights with Layovers

Travelers are advised to book direct flights to avoid delays during the busy summer season. However, Google Flights data shows nonstop flights are 20% more expensive than those with layovers, due to high demand. Whether the cost savings of layovers outweigh the inconvenience is a personal choice.

Timing Your Flight Booking for Maximum Savings

Contrary to common belief, buying airline tickets on a specific day, like Tuesday, doesn’t offer significant savings. Data over five years shows that purchasing on Tuesdays, Wednesdays, or Thursdays only saves an average of 1.9% compared to weekends. If your trip is soon, it’s better to book now instead of waiting for a specific day, to avoid potential price hikes.

Impact of External Factors on Flight Prices

Airfare can be significantly influenced by external factors, often beyond the control of airlines and travelers:

  1. Oil Prices: Flight prices may increase with higher oil prices, as airlines offset rising fuel costs.
  2. Political Stability: Areas with political unrest may see cheaper flights due to reduced tourism, while regions hosting major events can experience higher prices.
  3. Pandemics and Health Crises: Health crises like COVID-19 can lead to reduced flights and fluctuating prices due to changing demand and travel restrictions.
  4. Economic Conditions: Economic downturns can decrease travel demand, potentially lowering flight prices, whereas economic growth can increase travel costs.
  5. Environmental Factors: Severe weather or natural disasters can disrupt flights, affecting availability and pricing.
  6. Industry Changes: Airline industry shifts, such as mergers or bankruptcies, can impact market competition and airfares.

Awareness of these factors can aid in understanding and anticipating changes in flight prices, helping travelers make more informed decisions.


Finding cheap flights is possible if you plan smart. The best times to book flights depend on where and when you want to go. Booking at least a few weeks before your trip is usually best. Being flexible with your travel dates can help you find better deals too. Tools like Google Flights can track prices and show the best times to book. External things like oil prices or bad weather can make prices change, but travelers who do research and stay patient can still find affordable tickets.
