Cargo is often forgotten in the mix. In reality it is more a case of how much fuel is burnt for the revenue load or Payload flown. BA demoed the efficiencies afforded by flying newer aircraft a year ago. Given the information was made public I don’t see how it contravenes any guidelines given 1) old news 2)old data 3)happily made public by BA.

How revman divvy up the inventory of fares from flight to flight is a law unto them and no doubt these days is dynamic, but it is hard to know from a mere glance what revenue is generated when I see a pax fig of 216 vs say, 155. I may fly the same route from one week to the next, one has 11700 KGs of Freight and 3000 Kgs of baggage, the same flight a week later 4300 Kgs of freight and the same amount of baggage. All of that pays different rates so nailing down a figure of what pays what is difficult.

The front pages of the old ‘cirrus’ flight plans where published to show the difference an aircraft type makes of fuel burn and fuel loaded for the same route (LHR-JFK) operating the same flight on the same day (identical conditions) using the same payload. The route distance only varies by 5 nautical miles between the fleet data published. So form the data below the PL figure being payload in tonnes and the TIF and Taxi figures being fuel in KGs planned to be burned may give a more realistic idea of efficiency in terms of fuel per revenue generating kilo of payload.

All of this data is old now and we use a new planning system.
