NSW Premier Kristina Keneally has admitted she failed to declare free airline upgrades for her children during a trip to the US in 2008.
But Ms Keneally said she made no apology for failing to declare the upgrades, given by Qantas, saying the issue of free upgrades for politicians was a "grey area".
"I doubt you would find any member of parliament who has not been upgraded at some point either personally or professionally," she told reporters on Wednesday.

Upgrades while in ambassador role
The premier said her children received the upgrades when she travelling in her role as Sydney ambassador for G'Day USA.
"In my case I paid for my kids to go overseas and Qantas made the decision to upgrade them and I didn't declare that," Ms Keneally said.
Her admission comes after the state opposition on Wednesday called for the resignation of senior Labor MP Ian Macdonald.
Mr Macdonald had failed to declare he and his wife received free business class upgrades while travelling on Emirates Airlines in 2008, Fairfax Media reported on Wednesday.
Prior to that, in September 2007, Mr Macdonald as primary industries minister had authorised the thoroughbred horse industry to continue breeding operations in the Hunter Valley during the equine influenza outbreak.
