Australia's airline wars have entered another battle ground. This time it's the Wi-Fi wars - be it tweeting over the Tasman or joining the emile-high club, the race is on.

Virgin has become the first to announce Wi-Fi on international flights, and both Virgin and Qantas have now heralded the imminent arrival of this connectivity on domestic routes.

Qantas

Virgin released scant detail on when it would start the service or who its communications partners will be. It announced its intention as part of the official start of its new international business class cabin, a product that its chief executive John Borghetti says is best in class - albeit that's a claim Qantas may well dispute.

(Certainly when it comes to seat configuration Virgin's one seat on each window and two seats in the centre means no more climbing over the person lying next to you on route to the bathroom.)
