Our favorite discount carrier, offering cheap tickets with a side of additional fees, is back at it again with new routes. Frontier Airlines announced the addition of 18 new nonstop routes on Wednesday. 

The new flights will include the airline’s first route to El Salvador and Guatemala. There will also be an increase in flights out of Miami, which is also a major hub for American Airlines. 

Frontier is adding additional destinations in the Dominican Republic, including Santiago and Santo Domingo. 

It is common for Frontier to experiment with the routes they offer, launching most routes seasonally. However, if routes don’t do particularly well, they get pulled from the lineup — such as the service to Costa Rica which is no longer active. 

Although tickets are cheap, Frontier charges additional fees for carry-on bags, checked bags and beverages on the flight.
