A wages dispute between unions and a Qantas contractor will not affect the airline's domestic passengers, says Qantas.
Electrical Trades Union organiser Garry Rogers says Qantas contractor BCS Infrastructure Support locked out 26 maintenance workers at Brisbane Airport at 6pm (AEST) on Sunday.
Mr Rogers told AAP the lockout, which only affects the domestic terminal, is the latest in a bitter feud that has included strike action and is on Monday working with the contractor to resolve the dispute.
"I'm hoping to have this worked out this morning," Mr Rogers told AAP.
"We are working with the company but it is based in New Zealand and there is few hours time difference.
"If it's not, we will picket the airport and hand out flyers."
A Qantas spokes person told AAP the dispute would not cause passenger delays.
"These are not Qantas employees and this is a matter entirely for BCS," The spokesman told AAP.
"BCS are putting in place contingency plans and have advised us that this will not impact our operations."
Mr Roger says the dispute stemmed from pay inequality, given Brisbane workers were paid up to 25 per cent less than their Victorian counterparts.
