Frontier previously announced the Newark routes in August, but did not provide launch dates. The expansion followed Southwest's announcement that it would stop serving the New Jersey airport in November.

"Frontier is among the fastest growing airlines in the U.S. and we are excited to introduce 25 new routes including more flights from Newark, expansion in the Dominican Republic and Puerto Rico and new flights to Guatemala City and San Salvador," said Daniel Shurz, senior vice president of commercial at Frontier, in a statement.
