Lindblad Expeditions expects the coronavirus shutdown to make a limited impact to its results this year, with cruise bookings revenue ahead of last year as of mid-February.

The Sven-Olaf Lindblad-led owner foresees as much as a 20% improvement in revenue to $410m based on growing demand but does not know how the virus may change that outlook.

"Given the destinations we visit and the geographies where we source our guests, the Company currently anticipates limited direct impact from the COVID-19 coronavirus," the company said in a statement.
