Miri Airport is the main hub for MASWings Twin Otter fleet which took over the rural air services from FlyAsianXpress.

Its location in the middle of Malaysian Borneo close to the border of Brunei makes it a suitable hub for rural air services and an important gateway to Sarawak.

Several shops and dining outlets can be found in the airport, including Starbucks, Marrybrown and Famous Amos.

Malindo Air initially maintained its sales office on the first floor of the airport, just outside the departure hall, even though it has suspended flights to Miri from Kuala Lumpur indefinitely.

[9] Barely a few months later, Malindo Air once again terminated its route from Miri to Kuala Lumpur in April 2017.

[11] The expansion allows 4 additional parking bays for code C aircraft (i.e. Boeing 737 or Airbus A320 and equivalent) and 6 for ATR 72.

The apron can now accommodate 7 code C aircraft, 1 Airbus A330 or Boeing 777, 9 ATR 72s and 4 Viking Air DHC-6-400 Twin Otters at any given time.

For the comfort of passengers boarding and disembarking ATR 72s or DHC-6s, 3-fingered piers with covered walkways were also constructed in apron 'B', based on the walkways found in Low cost carrier terminal (LCCT) of Kuala Lumpur International Airport (KLIA) that is now closed.

Calls to upgrade the gateway to northern Sarawak have been voiced as the airport slowly reaches its maximum capacity.

[18][19] On 6 December 2011, the Minister of Transport Datuk Abdul Rahim Bakri said that Miri Airport will be expanded further to cater for the growing volume of passengers and cargo passing through it.

[20] Lee also pointed out the need for the airport to have separate terminals catering to domestic and international and rural air services.

An urgent meeting was held by Sarawak Communication Assistant Minister Datuk Lee Kim Shin regarding these matters.

[26] Once the extension was completed, the parking apron would be able to accommodate 8 Boeing aircraft and equivalent, 9 ATR 72 and 4 DHC-6 Twin Otter.

It was the part of the final work package contract (WPC 11), connects Sungai Tangap to Pujut Link Road.
