The agent/airline are adament the engines are dangerous goods and have just revised their quote to me
JKT - LHR 250kg was $1,327 now $3,360
As I said this may be a scam where they charge me the DG rate and it actually goes general cargo
It's going by sea freight with a different company I've used before ... $400
Going to buy a copy of the IATA Dangerous Goods manual so I can argue the case better next time
Thanks all
