I don't know what the sums are for these sort of goods for volumetric weight but for our industry airfreight is about £6.00 per KG it's up about 100% because of the lack of passenger aircraft whereas sea has went up from £0.21 - £0.80 kg. But the bigger sting is that felixstow is charging per container for ships unloading without taking the same amount back as and some ships are part unloading then moving on with the unloaded cargo.
