Track airline unit revenue and unit cost each month.
Finance & unit economicsAerospace & aviation
How it's worked out
- Load factor = RPK ÷ ASK. RASK = revenue ÷ ASK. CASK = cost ÷ ASK. Break-even LF = CASK ÷ yield
- Same period
NoteBreak-even load factor uses average revenue per RPK, so it shifts when fares change.
