The volume of cargo flown in m³ (as provided by the airline) displayed in Air Advanced is mostly determined by using one of the two following methodologies:AWB methodology — total combined volume (in m³) of all the AWBs (air waybills) loaded on the flightPosition methodology — number of positions used on the flight converted to m³ (assuming it was 100% full)Both methodologies have downsides:Airlines that use the AWB methodology are likely to underestimate the amount of m³ actually used on the flight, because it does not account for any stowage loss and mail.Airlines applying the Position methodology are likely to overestimate the amount of m³ taken up on the flight, because it disregards that the pallets might not be completely utilised.To normalize both methods, the m³ values used in Air Advanced that are based on the AWB methodology are increased by 5%, while the values based on the Position methodology are decreased by 5%.
