Fly Corporate sales manager Geoff Woodham confirmed that the regional airline will cease its services between Moree and Brisbane, with the last flight to be on Friday, March 8.

He said while the Moree route had a positive start in August 2016, recently there has been a significant decline in passenger numbers which has led to the company's reluctant decision to withdraw the service.

"We put a significant amount of work and resources into making sure Moree was successful but unfortunately we haven't got the response we believed we were going to get," Mr Woodham said.

"At the end of the day, the numbers don't stack up, the support's not there.

"It's just not viable."

Mr Woodham said although they did have loyal customers who supported the service, those numbers weren't enough to remain viable.

"There was part of the community that supported us very well; we did corporate sponsorship, and put a lot of investment into Moree, but we just didn't get that return," he said.

"As a business, if you don't get returns, tough decisions have to be made.

"We've also had very little contact with councillors to support what we're doing."

Moree mayor Katrina Humphries said the cancelling of the service is "unfortunate" for the community.

"I think it's another victim of the drought," she said.

"There's an old saying, 'use it or lose it' and if the patronage isn't there … it's what you need to do as a business.

"I believe it's a very sad thing because it's a service people have enjoyed very much. Hopefully they might see fit to come back to Moree when things pick again."

In response to the claim that council didn't support the service, Cr Humphries said as a Local Government organisation, council doesn't need to fly to Brisbane.

"It's unfortunate that council couldn't utilise the service because all our business is done in Sydney, not Brisbane," she said.

Passengers with bookings after March 8 were notified of the cancellation earlier this week. They will receive a full refund or the option to choose an alternative flight connection via either Narrabri or Inverell.

Mr Woodham said the Narrabri and Inverell services would continue to fly to Brisbane.

This week Fly Corporate also announced it would add Inverell to Sydney flights, via Narrabri.

Mr Woodham said they were able to do this as a result of cutting the Moree service.

Fly Corporate thanked all those who have utilised the service since its inception.
