The growth in airline traffic to DR continues to grow annually with new and changed flight schedules to the 7 international airports.
'arecoa' the MITUR publicity outlet is a good source of up to date information:

There is also a growth of Dominican Airlines after the demise of PAWA:-
Air Century are based at Santo Domingo's second airport commonly known as La Isabela at the north end of the city but with excellent access from the ring road. It is a quiet airport and easy to pass through and a base to both Air Century and the Haitian airline Sunrise Airways.
Air Century has grown steadily over the years and now operates scheduled services to San Juan, PR, Havana, Curacoa, Aruba and St Martin plus Haiti with more planned. They use Saab 340B turboprops, BAE Jetstream 31/32 and Bombadier CRJ200 aircraft and also have Cessna Citacion VII for charters. https://www.aircentury.com/en/
I have personally flown them numerous times to San Juana and also to St Martin and found them to be a reliable and punctual carrier who is getting better all the time.
Sky High Aviation are a Santo Domingo SDQ based airline which is beginning to grow strongly with much needed scheduled services to many island destinations to include San Juan, Ponce and Aguadilla in Puerto Rico, Curacoa, Aruba, Bonaire, St Martin, Tortolla, St Kitts, Antigua, Dominica, Anguilla, Haiti, and the USVI. Flights to Colombia are planned.
Their fleet include Beechcraft 1900 and Embraer 145. https://skyhighdominicana.com/en/home-2/
Flights around the Caribbean are getting more difficult and earlier this month I chose to fly with them to St Kitts and back via St Martin. They were event free flights on the Beechcraft 1900 which by the way does not have a bathroom and clearly they are working hard to improve customer service at all levels. They lack English speakers at sales and don't include all the airport taxes in the ticket price.
Flycana which was formally known as Dominican Wings operates out of Punta Cana using Airbus A320 and has a growing networks of international destinations. https://flycana.com/nuestro-negocio
I have no experience of this airline
