Loganair is expanding its network from Newcastle airport for next summer.
Almost 200,000 seats will be available from March following a strong travel recovery in 2022.
A second Embraer ERJ-145 regional jet will be based at the north-east airport to allow increased frequencies.
Double daily flights to Aberdeen will return, together with the addition of a connection to Oslo via Aberdeen.
A Newcastle-Southampton service will rise from two to three flights a day
Newquay and Bergen will be served twice a week, while flights to Exeter have been boosted from three to up to five a week.
The pre-pandemic frequency of up to five flights a week between Newcastle and Stavanger also return.
Chief commercial officer Luke Lovegrove said: “This bumper schedule for 2023 underlines our commitment to Newcastle with our biggest ever programme for the city, offering customers more choice of destinations, frequency and capacity than ever before.
“It has been a very positive year for Loganair at Newcastle and we are excited to see that success continue into 2023.”
Airport aviation development director Leon McQuaid added: “This biggest ever capacity increase by Loganair is a great vote of confidence in both the airport and the region, and further strengthens our partnership.
“The investment will provide more choice for passengers flying from Newcastle, create more jobs at the airport and across the wider area, and increase opportunities for the attraction of inbound tourists to the north-east.
“Loganair also provides connectivity to important business destinations, so this announcement will further boost the growth in business travel.”
