TORONTO — Porter Airlines is now eyeing May 19, 2021 as a possible return-to-service date.

Porter announced today that it was pushing back the resumption of flights until that date, amid ongoing travel restrictions. In early January the company had been hoping to restart on March 29.

“The implementation of more restrictive travel rules by governments since our last update makes an early spring restart unviable,” said Michael Deluce, president and CEO of Porter Airlines.

“While there are signs of progress in containing the pandemic, it is necessary to reset our sights based on changing conditions. We remain optimistic that things are moving in the right direction, but it is possible that this tentative date may also need to be modified if vaccinations don’t accelerate to enable the easing of travel restrictions,” he added.

Updates will be provided in the coming weeks about the status of Porter flights.
