To see how different generations perceive travel, online travel marketplace Priceline commissioned research firm Savanta to survey 1,503 consumers between the ages of 17 and 65. The data, which came from consumers who had traveled for vacation at least once in the past year, resulted in the Priceline Generation Travel Index.

One thing all generations agreed upon was that cost could enable or hinder one’s travel plans. However, the older respondents were, the more weight they gave that notion.

Among respondents, 86% of baby boomers said cost was the most important consideration when traveling, followed by 80% of Gen Xers and 75% of millennials. In comparison, only 67% of Gen Zers were most governed by cost when making travel decisions. Gen Zers were also the generation most likely to consider themselves to be “big spenders” when on vacation.
