Police have begun meeting flights from Sydney at Orange Regional Airport to ensure passengers are not breaking COVID lockdown rules.
An Orange City Council spokesman said police had informed them of the plan.
Flights into Orange have also been reduced this week as airlines experience less demand.
Face masks are mandatory across NSW on public transport and taxisNSW Health
QantasLink cut its normal two flights on Tuesday to one and its next flight to Orange is not until Thursday.
Another airline Rex said it was still operating to and from Sydney despite the state's two-week lockdown.
"Although the frequency of services has been reduced to meet lower passenger demand, Rex continues to fly between Sydney-Melbourne, Sydney-Gold Coast, Sydney-Canberra and importantly between Sydney and all NSW regional cities serviced by Rex to ensure that essential travel can be undertaken for eligible travellers," it said.
Compulsory mask wearing and increased social distancing have also come into effect on public transport in Orange and NSW this week.
The latest changes to public health regulations announced last Saturday are now in full swing.
NSW Health has called on people to limit non-essential travel and stay away from Greater Sydney where practical.
"Face masks are mandatory across NSW on public transport and taxis, rideshare and hire car services," it said.
"You shouldn't travel to Greater Sydney unless it is for an essential reason and you will need to observe the [14 day] stay at home order when you go back home."
Changes have been made to rail travel with less seats available in each carriage.
"NSW TrainLink Regional coach and rail services will be booked at a COVID-safe capacity to allow for physical distancing, in line with NSW Health advice," it said.
"Extra cleaning continues across the network."
Meanwhile a steam train due to provide a ride between Orange and Parkes and return on Tuesday was cancelled due to the COVID situation.
Organisers said all tickets for the Central West Picnic Train would be refunded within seven days.
