Frontier Airlines launches three new Miami links Primary tabs 10th March 2021 Services to Cancun, Punta Cana and the St Thomas will commence this spring Frontier Airlines – a Colorado based low-cost carrier – has recently celebrated the launch of its services at Miami International Airport to three new destinations which begin this spring. The new connections to Cancun in Mexico will run four times a week, alongside new rotations to Punta Cana in the Dominican Republic and St. Thomas in the Virgin Islands which will be operated twice weekly. Introducing three new routes from Miami is part of the airline’s expansion which began in December with the implementation of three weekly flights to Santo Domingo. This was then followed by the launch of its daily service to Orlando last month.
