Hello and thank you for asking Wonder! I understand that you are seeking the companies in the US that do the most corporate travel by duration. The most helpful result I found was rankings from Business Travel News. During my research, I found that statistics based upon trip duration were not available, as this topic does not appear to be tracked that way. The best available rankings on this are by the amount of money spent on US airfare, so that has been included. Other data on the topic tends to be around industries and job types that travel the most, rather than specific companies. In short, top companies include IBM, Deloitte, Boeing, GE, and more.
BUSINESS TRAVEL SPENDING
Each year, Business Travel News releases a list of the biggest corporate spenders on travel. Their list is based upon the amount that is spent on air travel in the US. The most recent list that has been released is for 2016, which is based upon travel in 2015. Within the top 10, three of them are not US-based companies, so I have provided a top 13 list.
