New York City is the most expensive place in the world to host a business trip, with a daily average cost of $866, according to new data from global mobility experts ECA International.

“The high demand for hotels in New York is reflected in the premium rate that rooms are currently charged at, averaging $556 (£392) per night at a 4-star hotel,” said Simon Franklin, daily rates manager, ECA International.

“The high cost of hotels, transportation and mandatory 15–20 percent tipping policies during meals out, contribute to the US city being the most expensive in the world for business travel.”

The second most expensive was Geneva, Switzerland, also the most expensive in Europe, costing an average of $786 a night. Next came Zurich ($729), followed by a few unexpected destinations — Luanda, Angola, and Bridgetown, Barbados — then Paris, Nassau (Bahamas), Washington, D.C., Basel, and Monaco.

“Swiss cities, once again, dominate the most expensive places for business trips in Europe, with five different locations in the top 10 (and three of the top 10 globally),” said Franklin.

“Switzerland has always been an expensive nation for business travel and this year is no different as the Swiss franc has performed very strongly.”
