Thousands of Bonza customers affected by the airline going into administration and cancelling all services won't receive refunds anytime soon as flights remain grounded until next week.
On Tuesday, the low-cost carrier abruptly suspended all flights across the country due to concerns over its business viability before entering voluntary administration.
All of its fleet is currently grounded amid discussions about whether the airline can continue operating and employ its workers during the administration period.

Administrators Hall Chadwick said stranded customers will not see a refund while the situation remains murky.
"Unfortunately, the administrators and/or the company are not in a position to process or issue refunds at this point in time," Hall Chadwick said in a statement.
"We understand how frustrating this is and we appreciate customers' patience at this time."
Affected customers wanting information on their entitlements can call Hall Chadwick's hotline on 03 8678 1600.
There have been 3590 passengers affected by the cancellations and rebooked on either Qantas, Jetstar or Virgin flights without charge, according to Transport Minister Catherine King.
The government hotline on 1800 069 244 has received about 2800 calls for help from customers.
The hotline will continue to operate until 5pm tomorrow. After then, Bonza customers are urged to contact Qantas, Jetstar and Virgin directly for a booking.
Hall Chadwick has also extended flight suspensions, which were set to end today, until Tuesday next week.
"Customers with bookings during this period are advised not to travel to the airport," the firm said.

"Customers scheduled to travel during this time are requested to make alternative arrangements with other airline carriers."
Bonza's website isn't accepting any bookings.
The regional airline was founded in late 2021 and only began flying last year.
