Virgin Australia's bid to capture more corporate travellers will move up a notch from the end of September when it starts offering business class seats on all flights to Perth from Brisbane, Melbourne and Sydney.

The move extends the business class offering launched in May this year, when Virgin started flying two wide-bodied Airbus A330s between Sydney and Perth that feature 27 seats at the pointy end of the aircraft.

The airline has said that from September 28, all flights to Perth from Australia's eastern capitals would feature business class.

Virgin operates 68 flights a week between Sydney and Perth, 56 a week between Melbourne and Perth and 34 a week between Brisbane and Perth.

The A330s would remain on the Sydney-Perth route three times a day, with new or refitted Boeing 737s that have eight business class seats with a 38-inch pitch used for all other flights.

As an introductory offer, Virgin said it would offer complimentary limousine services on departure and arrival for all business class passengers between September 28 and November 11.

Fares start from AU$1399 ex-Sydney, AU$1299 ex-Melbourne and AU$1499 ex-Brisbane.

The airline has launched new airport lounges, a new frequent flyer program and has forged alliances with international airline partners in a bid to snare 20 per cent of the corporate travel market, which is dominated by Qantas Airways.
