Republic Airways Holdings said on Thursday that February traffic doubled from the previous year after it added Frontier and Midwest airlines to its stable.
Republic said traffic rose 104 percent to 1.41 billion revenue passenger miles, or one passenger flown one mile. Adding Frontier and Midwest made up for a drop-off in Republic's old business of flying under contract for major airlines.
Combined traffic for Frontier and Midwest grew 8 percent to 835 million revenue passenger miles.
Capacity across Republic's combined system grew 188 percent to 1.95 billion available seat miles. Republic's fixed-fee flying fell 22.3 percent to 806.7 million available seat miles. Capacity at Frontier and Midwest rose 5 percent to a combined 1.15 billion available seat miles.
Occupancy across the combined system rose 5 percentage points to 72 percent.
Indianapolis-based Republic bought Midwest in July and Frontier in October. It also owns Chautauqua Airlines and Shuttle America.
For the first two months of the year, Republic's traffic rose 112 percent to 2.93 billion revenue passenger miles. Capacity rose 95 percent to 4.17 billion available seat miles. Load factor was up 5 percentage points to 70 percent.
