Frontier adding flights to Dulles from Charlotte Douglas

Denver-based Frontier Airlines said Tuesday that it plans to add regular service from Charlotte Douglas International Airport to Dulles International Airport in suburban Washington, D.C., building on the low-cost carrier’s presence in Charlotte.

The Charlotte-Dulles flights are set to start Aug. 20 and will run five times a week, on Monday, Wednesday, Friday, Saturday and Sunday. The move is part of Frontier’s expansion at Dulles, where the company is adding flights to 14 destinations.

The flights will be operated on Airbus A320 jets, which seat 168 passengers in a single class (though travelers can pay extra for seats with more legroom).

The airline is holding a sale through Saturday with one-way flights for $39.

Frontier recently started service four times a week from Charlotte to Trenton, New Jersey.

The airline is similar to other so-called ultra-low-cost carriers such as Allegiant Air and Spirit Airlines. Frontier charges low base fares but adds fees such as $25 to $50 for a carry-on bag and $3 to select a seat.
