Are there any low-cost airlines operating from Europe to Dominican Republic?
Wamos Air (formerly Pullmantur Air) offers weekly service (on Mondays) between Madrid and Punta Cana from about €200 each way.
I was looking for local flights (from an european country to an overseas territory of the same country) like Paris to Martinique or Guadeloupe because I thoguht this type of flight would be cheaper. As I was searching I found XL Airways France. They have a Paris <--> Punta Cana flight for around 500 euros.
Norwegian just started flying to Puerto Rico (San Juan). It can be as cheap as 4,000 SEK
