If you want to travel to Europe during the summer (when, admittedly, everyone else wants to travel to Europe) you definitely can’t procrastinate. “Prices typically rise through the spring and peak in June as summer arrives,” Hopper’s data science team determined. And if you plan on traveling during a summer holiday — Memorial Day, the Fourth of July, Labor Day — the best fares can typically be found at least three weeks in advance of your departure.
As was the case last year, not a single airline from Europe or the Americas made the overall top 10 list. That is something of a surprise considering Delta, like Qatar Airways, introduced a new all-suites business class last year. Also like previous years, the rankings are significantly skewed toward the Asia-Pacific region. This should not be a surprise considering the massive growth of aviation in that part of the world, which is only projected to continue increasing in the coming decades.
