Google is already making an impact with its soup-to-nuts suite of planning and booking tools. Last year, Google came in second to Expedia for one-stop shops travelers consider, according to the Portrait of American Travelers study by travel and hospitality marketing firm MMGY Global. The same study showed preference for Expedia had dipped to 64% in 2018 from 67% in 2017.

So far, Amazon has only dipped its pinky toe into the travel waters but there’s some evidence – and intense speculation – that something bigger is coming.

Both internet giants bring the kind of vast resources and big-data reservoirs that allow them to dramatically change how we book trips.
