UAE-based RAK Airways will begin operating to Islamabad and Amman next month.
Flights to the Pakistani and Jordanian capitals will begin on 5 and 7 August, respectively.
These are the first new routes the Ras Al Khaimah-based airline has launched this year. It is to add five other destinations "within the next few weeks", says president and chief executive Murabit Al Sawaf.
Islamabad is RAK Airways' third destination in Pakistan. It launched twice-weekly services to Lahore and Peshawar in 2011, and in the first half of this year, it boosted frequency to three flights per week on each route.
Flightglobal's FlightMaps Analytics data shows that Islamabad is already served from the UAE by Etihad Airways, Emirates, Pakistani International Airlines and private Parkistani carriers Shaheen Air and Airblue.
In terms of capacity, Emirates is dominant, accounting for nearly 40% of seat capacity and 38% of available seat-kilometres, but Airblue has the highest frequency of flights.
Air Arabia, Emirates, Etihad, Flydubai, Royal Falcon and Royal Jordanian fly to Amman from the UAE, with Royal Jordanian the dominant carrier.
