Lindblad Expeditions is yet another cruise outfit to push out its fleet lay-up even further amid the debilitating coronavirus pandemic.

The Sven-Olaf Lindblad-led owner of 15 expedition cruiseships will now keep its vessels at anchor to July, the New York-listed company announced Friday in its first-quarter earnings report.

"Due to the spread of the Covid-19 virus and the effects of travel restrictions around the world, the company has suspended or rescheduled the majority of our expeditions departing March 16, 2020 through June 30, 2020 and has been working with guests to reschedule travel plans and refund payments, as applicable," the company said.
