Frontier Airlines announced on August 28, 2018, the 100th city in the low-fare carrier’s network and the addition of six new routes to its network.

The airline will add new, low-fare services to/from Harlingen, Texas, with the only non-stop service to Denver, Colorado, and Chicago, Illinois, as well as international service from Las Vegas, Nevada, with non-stop flights to both Cancun and Cabo San Lucas in Mexico.

In addition to low fares for Harlingen being the carrier’s 100th city served, the non-stop flights to Denver – Frontier’s hometown – mark an important milestone for Denver International Airport (DEN).

The addition of the service to Harlingen brings the number of domestic destinations available from Denver to 179, which represents the most domestic routes that any U.S. airport serves.

Additionally, Frontier will introduce new service from Chicago O’Hare International Airport (ORD) with flights to Palm Springs, California, and from Philadelphia, Pennsylvania, to Sarasota, Florida.

All in all, the carrier will now offer 31 non-stop destinations to/from Las Vegas, 19 destinations to/from Chicago, 24 destinations to/from Philadelphia, and 2 destinations to/from Sarasota.

“With the addition of this one-hundredth new city to our network, and six new routes, we continue to deliver on our mission to make air travel more affordable for America,” said Barry Biffle, President and CEO, Frontier Airlines.
