Qantas Airways has returned to normal flight operations following the end of a labour crisis that spurred Australia's flag carrier to ground its fleet for two days.

"Qantas flights have returned to normal today [1 November] with all flights operating on time and as scheduled," Qantas said in a statement. "The majority of international passengers across the Qantas network were accommodated on services yesterday afternoon and overnight."

Qantas said its domestic operations have also returned to normal, with the backlog of passengers likely to be cleared by early Tuesday afternoon Sydney time.

Qantas recommenced flights on Monday after grounding its fleet for almost two days. The carrier resumed services after the Australian industrial court ordered an end to all industrial action by the Australian Licensed Aircraft Engineers' Association (ALAEA), the Transport Workers Union (TWU), the Australian and International Pilots Association (AIPA) and Qantas.

Under the orders issued by Fair Work Australia (FWA), there will now be up to 21 days of negotiations between the parties.

No industrial action can take place during this period and if no agreement is reached, binding arbitration will take place under the control of the FWA.
