With both Qantas and Virgin Blue increasing their fares recently your corporate travel budget could be stretched to the limit. However, there is some good news, as Tiger Airways has said it has no plans to up their fares for customers. The low cost carrier has not ruled out raising prices in the future and intends to monitor the price of jet fuel. Virgin Blue’s domestic one-way flights will rise by $5 to $10 while Pacific Blue trans-Tasman and short haul international flights will be put up by $5 to $15, as from May 6 2008.
