Hi, we just moved to England from Canada and we shipped our stuff on a vessel. It takes longer, but it is way less expensive then cargo flights... To give you an idea, we paid 5500$ for 300 cubic feet (I don't know the weight) but it was pretty heavy, mostly clothes and personnal belongings (no furniture). To bring our dog here, it cost us 3500$ on cargo (crate is 20 cubic feet) and the weight with the dog was 115 pounds... best thing to do is to get quotes from moving companies as it may vary widely from one to the other. Good luck
