Frontier Airlines announces 15 new nonstop routes out of Newark, $15 flights

Frontier Airlines will begin offering service at Newark Liberty International Airport this fall, and offering introductory fares as low as $15 on some flights.

The discount carrier announced Tuesday that it will start offering nonstop routes in mid-November to Las Vegas; Miami; Orlando, Florida; and San Juan, Puerto Rico.

Flights to Phoenix, Atlanta and West Palm Beach, Florida, will begin in December. Frontier said flights to cities including Tampa, Florida; Punta Cana, Dominican Republic; Cancun, Mexico; Chicago; and Raleigh-Durham, North Carolina are planned for the spring.

Last month, Southwest Airlines said it was pulling out of Newark and consolidating its service at New York's LaGuardia Airport.

Newark Liberty International, operated by the Port Authority of New York and New Jersey, handled 46 million passengers last year, 12th-most in the country.
