British Airways World Cargo has reported commercial revenue – flown revenue plus fuel surcharges – of £175 million (US$273.3 million) for the first quarter of the financial year beginning April 2010. This represents an increase of 36.7 per cent against the same period last year. Excluding the impact of favourable exchange rate movements, commercial revenues were up 34.6 per cent. Volumes of 1.1 million cargo tonne kilometres (CTKs) for the quarter year represent an increase of 2.1 per cent versus the same period last year. Cargo capacity for the same period was down 4.7 per cent. Overall yield (commercial revenue per CTK) increased by 33.9 per cent versus the same period last year, driven partly by an improved premium product mix and underlying market conditions. Excluding the impact of exchange rate movements, yield increased by 31.8 per cent.
