Just wondering is there a service whereby a courier will coem onsite to pick up luggage and be able to ship them door to door into the UK.

As I am not planning to pack everything with me and just want to put everything in 4 suitacases. However for my HKG-LHR leg I prob have to travel on BA (due to the attractive I Class fare and CX still haven't published the new year's fare yet ex TPE). So I can't use my DM MPO extra bagage allowance. MAx I can take it prob 2 suitacases.

If such a service exist I wouldn't mind using it, and I dont' need it to be same day as well.
