The chief executive of Tiger Airways has resigned as the low-cost airline remains grounded on the Australian continent.

The news came immediately after Australian aviation authorities said they would move to keep Tiger’s license suspension in place least through the end of the month due to ongoing safety concerns. Tony Davis, president of Tiger Airways Holdings, has taken the place of former CEO Crawford Rix after recently flying to Australia from his airline’s Singapore base to engage in talks with the Civil Aviation Safety Authority (CASA).

The carrier has said that it was working hard to get its planes back in the air as quickly as possible and added that it would not refute Australian officials’ decision to keep flights grounded through July. CASA is expected to be given the green light for the ban extension on Friday from Australia’s Federal Court on the grounds than its inquiry into Tiger’s safety practices hasn’t yet been completed.

Meanwhile, the ban continues to affect travel plans for around 9,000 passengers per day, as all of the airline’s 60 daily domestic flights have been cancelled until at least the August 1. The airline is refunding passengers with reservations through July 31 and is no longer selling domestic tickets, which airline officials was done voluntarily rather than due to orders from CASA officers.
