Porter Airlines is extending its flight suspension until 03AUG due to ongoing COVID-19 travel restrictions, according to the airline's website.
In the same statement, Porter says it is preparing to introduce more health and safety measures which will be announced, "closer to when flights restart."
The airline is also waiving change and cancellation fees on all fares booked until 20JUL 2021, which also applies to Porter Escapes Vacation packages.
"We want to see our planes in the sky as soon as possible and are actively working to prepare for our resumption of service. However, the ongoing uncertainty presented by government travel restrictions, including border closures, is impacting our ability to operate flights. We are closely watching developments and know that Porter will be an important part of providing people with travel options as the economy recovers," said Porter in the statement.
