Frontier Airlines announced four new express routes out of Pittsburgh International Airport starting this spring. 

During a press conference Thursday, officials from Pittsburgh International Airport and Frontier announced that the airline is launching nonstop services to Atlanta, Philadelphia, Raleigh and Dallas. 

Starting May 16, three weekly flights will be available to Dallas-Fort Worth and two weekly flights will be offered to Philadelphia. On May 17, flights will be available to Atlanta and Raleigh four times a week. 

The expansion more than triples Frontier’s network at PIT, which already includes nonstop service to Denver and Orlando. To celebrate the new routes, Frontier is offering introductory one-way fares starting at $19 if purchased by Dec. 19.

Currently, travel can be booked through August 12, 2024, on the airlines website
