Frontier will soon fly to 15 cities out of Newark (including Chicago, Dallas) and is offering $15 fares to promote it

Low-cost airline Frontier Airlines is coming to Newark — and doing so with a most unusual offer.

The airline announced Tuesday it will be introducing non-stop service to 15 locations in the coming months — including Chicago, Dallas, Orlando, Las Vegas and even Cancun, Mexico — and will celebrate the announcement with $15 fares.

Four routes will begin Nov. 14 (Las Vegas, Miami, Orlando, San Juan, Puerto Rico).

Three routes will begin Dec. 10 (Atlanta, Phoenix, West Palm Beach, Florida).

The remaining eight routes will begin next March and April (Chicago, Dallas, Denver, Ontario, California, Raleigh-Durham, Tampa as well as Cancun and Punta Cana, Dominican Republican).

Tickets for the routes starting in November and December are on sale now at Frontier’s website.

The company, which said the announcement marks the biggest splash it has ever made at a new airport, is attempting to capitalize on the exit of Southwest Airlines, which will stop flying out of Newark Nov. 3.
