First Aberdeen has announced plans to increase services from this Sunday.
The operator says that many routes will operating increased frequencies in evenings and on Sundays across the network - with timetables returning closer to normal levels.
It comes as it has reduced the physical distancing rule to 1m on its services, with an enhanced cleaning regime to protect people from coronavirus.
But the firm says some services will still be restricted - and customers are being asked to check the First Bus website before travelling.
David Phillips, operations director First Aberdeen, said: "We are looking forward to welcoming back even more customers over the coming weeks and months as the vast majority of services now begin to operate nearer to pre-Covid timetable levels.
"This means that with social distancing still in place, we will have many more seats available than in recent weeks and services operating at higher frequencies.
"We know that this additional capacity and frequency will be a great relief to some commuters, as well as customers considering their first journeys for leisure purposes.
"We are grateful to all our customers for adhering to our on-board measures and thank them for their support. These measures, together with enhanced anti-viral cleaning and the increase in frequency provide reassurance to our customers that our services are safe and reliable. We are delighted to play our part in helping to get the local economy moving again."
