Qantas is to bypass Perth with new direct services from Melbourne and Sydney to the mining and energy resources hub of Karratha.
The flights, which will start in May, come after _The West Australian _revealed last week that resources companies were planning to fly workers direct from the Eastern States to resource centres because of difficulties in getting take-off slots at Perth Airport during peak times.
According to the Chamber of Minerals and Energy of WA, up to 27,000 new jobs are at risk over the next three years.
Last week, three resources giants said they were looking at altering their fly-in, fly-out strategy because of limitations of early morning take-off slots at Perth Airport between Tuesday and Thursday.
The airport faces major capacity challenges between 5.30am and 7am midweek, a critical period - from a roster perspective - for the workforce movement requirements of the fly-in, fly-out operations.
The airport is not planning to build a second parallel runway to relieve congestion for 20 years.
Last week, Perth Airport chief executive Brad Geatches said "to date" the airport had been able to handle the demands of airlines during the morning peak period.
The airport has claimed air traffic control improvements to be made by Airservices Australia and high-speed taxiway exits will "significantly improve" its ability to handle the peaks.
However, an Airservices Australia spokesman said "the improvements would be insignificant".
Perth-based Skywest Airlines is also looking at a Melbourne-Karratha service after it gets its first long-range Airbus A320 in July. It recently re-launched a weekly Melbourne-Kalgoorlie service.
Qantas already operates between Brisbane and Karratha.
The new services will allow resource companies to source labour from other areas and give North-West residents direct access to Sydney and Melbourne.
Rob Gurney, group executive Qantas Airlines commercial, said yesterday the airline was "committed to supporting the increasing demand for air travel in and out of Western Australia during this period of strong economic growth".
"The new schedules have been developed in consultation with key customers," Mr Gurney said.
