Air New Zealand has reached capacity on flights from the resort to Auckland and no seats are available until next Thursday.
On the same route Jetstar, which operates two flights a day between the destinations carrying up to 180 passengers on each, is nearing capacity.
There is some availability on Saturday but after that, the next available seats are on Thursday.
People hoping to fly to Christchurch from the resort with either carrier would also be hard-pressed to find a seat.
Jetstar flies to Christchurch via Auckland and has capacity on one flight on Saturday, but no other seats are available until Thursday.
Air New Zealand operates 33 return flights a week to Christchurch. It has capacity on that route today and no other seats are available until Tuesday.
Additionally it operates 37 return services between Queenstown and Auckland a week, each has capacity for 171 passengers.
A spokeswoman said the airline was ''currently experiencing stronger than usual demand for services between Auckland and Queenstown''.
''We believe a key factor driving this demand is Chinese New Year.''
There was increased inbound traffic on services from China and Hong Kong and many of those people were including Queenstown on their itinerary.
The airline boosted capacity by about 10% to the resort late last year, but at this stage it had no plans to increase it further.
However, three A320s to be delivered over the next couple of months, replacing Boeing 737s, would provide additional capacity.
A Jetstar spokesman also believed the demand for flights to Auckland was due to Chinese tourists, many of whom would be returning home to celebrate the Chinese New Year.
Jetstar had ''currently no plans to increase Queenstown services'', despite the number of international visitors, particularly from China, showing no signs of slowing.
In October Queenstown Airport Corporation chief executive Scott Paterson urged both airlines to boost capacity from Auckland and Christchurch to meet an expected surge of tourists between November and March, following increased flights to Auckland and Christchurch from Asia.
Yesterday China Southern Airlines announced more flights to Auckland from Asia.
