Yesterday we highlighted a new report by Concur, the annual “Expense IQ Report” on trends data around business travel habits, based on the $50 billion expense transactions per year that it processes.

Today, two fascinating charts from it, the list of most expensive cities for business travel, both international as well as U.S. cities.

On the first, international cities, Australia once again takes four of the top 10 most expensive cities to visit for business travel. If this list included U.S. cities, New York would rank ninth on this list pushing

Paris to tenth.

And second, the U.S. cities, New York City claims the top spot for most expensive U.S. city for business travel in 2012, which makes sense considering the lodging costs. Long Island City makes an appearance too, though not sure why it was given as a separate expense item in receipts from NYC.
