The actual quote was:
Stephen Thompson, Qantas' head of international sales, told the Sydney Morning Herald: "What the market will notice is Qantas international becoming more commercially nimble, which is a reflection of the ultra-competitive environment we're in."
May and June tend to be slack months for travel, falling as they do between Easter and the summer peak, nevertheless this cancelling of flights is a relatively new trend and is not being undertaken by every carrier.
It appears that this is NOT something which has occurred previously, it could be that loads were light, but they were never actually cancelled./QUOTE]
I had always thought February, May and November were the slackest months for travel for both airline and surface travel such as interstate rail operators.
However northbound from Oz to London and Europe I am surprised that June could be considered a slack month. It's when some Australians go to Europe for the summer.
