The Bermuda Post Office is seeking alternative routes for international mail, which has been halted by the Covid-19 pandemic.A spokeswoman this afternoon said the BPO was “working diligently” with partners overseas, including the United States and Britain.Sending mail to the US, UK and Canada “cannot be guaranteed at this time”, she said.In the US, mail arriving for Bermuda is being returned to senders, while mail from the US to Bermuda is expected to resume when LF Wade International Airport reopens to commercial flights.Mail from Britain has been routed to a container ship, with a shipment expected to reach the island by the second week of June.Once received, it will be delivered within four working days.Mail from Canada is on hold until the airport reopens and Air Canada resumes service.The BPO spokeswoman said the public would be notified on any developments.
