We are travelling with Singapore Airlines from Manchester to Christchurch in January. From a previous thread by Red Devil, we have seen we are allowed 40kg per passenger (max 32kg in one case). That gives us a total of 10 suitcases (plus 5 lots of cabin baggage and laptops).
So, we have got to buy 8 suitcases (already got 2)! Any suggestions on what size cases people buy? Some seem to quote size in inches or centimetres, others quote capacity in litres. Prices vary dramatically and we've got to multiply the price by 8..and then never use the majority of them again.
