So burying the hatchet to form a group to lobby suggests airlines are worried. They have already signalled their profits are trending down and want to get on the front foot with a new voice to challenge airport fees, government agency charges at airports and border taxes.
On flights across the Tasman, a route which ranges from ''challenging" to a ''bloodbath" for airlines, fees, taxes and other charges can make up 40 per cent of the price of a ticket.
Speeding up glacial progress in making transtasman flights more like domestic travel is also an aim.
In Australia, Qantas has concerns about federal passenger movement charges which have ballooned to around $65, regional airport charges and those at the country's main airports.
In New Zealand regional airport charges worry airlines, Auckland Airport is about to release details of a new charging regime and the Kiwi carrier is adamantly opposed to Wellington's runway expansion.
While Auckland Airport says it is spending $1 million a weekday on airfield and terminal infrastructure it has a look of a considerable catchup about it. Airlines have pointed to heavy spending by the airport on its own retail operations, property development and generous returns to shareholders.
Difficulties many passengers have had getting to and through the airport at peak times has infuriated Air New Zealand and other carriers but they have been reluctant to vent openly about it. There's been an aversion to going it alone.
Hence the new lobby group. It will be chaired by Australian competition expert Professor Graeme Samuel, the former chairman of the Australian Competition and Consumer Commission whose professional career has spanned senior roles in law, investment banking and public service. He is by all accounts, not backward in coming forward.
You'd be struggling to get much sympathy for airlines in regional centres where just one operates and practically charges what it wants.
But on most routes there is unprecedented competition. Airlines in the Asia Pacific are forecast by the International Air Transport Association to make about $5 profit for every passenger carried this year - a little over the price of a cup of coffee.
There's undoubted airline self interest in keeping down external costs but there's a spin-off for passengers. The carriers have a new voice.
Let's hear it.
