Kayak has launched a data center that reveals patterns in air travel as a result of the coronavirus pandemic. 

The data center offers information on global flight search trends relative to the same day last year, domestic versus international search trends, and search trends by destination city. According to Kayak, the data will be updated daily through at least the end of the year.

Kayak search data reveals:

• Flight searches in the United States, France, United Kingdom, and Germany reached their lowest point between April 6-8. Flight searches started trending upwards in May. In Latin America, flight searches are continuing to trend downward.

• In the U.S., international cities like London, Tokyo, and Paris are being replaced with searches for Anchorage, Miami, and San Juan. In Europe, cities like Milan, Venice, Nice and Ibiza are seeing the biggest drops, replaced by searches for towns in Portugal and Greece.

• Domestic travel searches in the U.S., Europe, and Asia Pacific are growing at a faster rate than international searches. Australia, Spain, the United States, and France are seeing the biggest shifts to domestic.

• Across the globe, cities with eased travel restrictions are gaining momentum the fastest. In the U.S., Las Vegas saw the biggest spike in searches following the reopening of casinos. Southern cities are a close second. In Europe, it's Italy, France, and Portugal. In Asia Pacific, searches in South Korea, Taiwan, Australia, and Japan are returning to 2019 levels for some major domestic destinations.

• U.S. searches to Europe are down 65% YoY.

Kayak also developed an interactive Travel Restrictions Map detailing entry restrictions by state and country.
