I will be flying from Portugal to the Netherlands but I will be only taking hand luggage. What is the cheapest ways of bringing more luggage (excluding the air plane)? (around 30kg).
This question can be extended to Europe. It's not the first time I have had this problem. What is the most affordable way of transporting luggage if you don't carry it along with you while travelling?
Note: Usually companies like TNT and UPS mainly work with other companies. If you ask them a quote it's either very expensive or you will hear a "No". Mail services are usually very limited in weight and are very expensive.
Note2: feel free to give any comment on time constraints. I think this may be useful. I've been in both situations: Where the time for my belongings to arrive was not very important and the opposite while travelling for short periods.
Note3: This question is getting more relevant with low cost plane companies charging extra for luggage. E.g.: When you travel from A->B->C, sometimes it would be very nice just to have things shipped directly from A to C. You may save money and you travel light.
