Loganair is increasing seat capacity by 30% on its Birmingham-to-Aberdeen flights from summer 2023.
The Scottish carrier is doing this by deploying larger aircraft capable of taking more passengers.
Luke Lovegrove, chief commercial officer at Loganair, said: “As we see growing demand across a number of services, we are thrilled to expand our offering.”
Tom Screen, aviation director for Birmingham Airport, added: “This strong regional connectivity supports economic growth.”
