You may think that black luggage looks sleek and sophisticated but when you attempt to pick out your luggage at the airport carousel you'll realise that 90% of travellers use black luggage.
If you don't want to be part of the 90% struggling with an array of identical bags then choose colourful patterned luggage.
If you're already one of the 90% add a colourful luggage label (not the one provided by the travel company) or put a few stickers to each side of your case and you'll never be fighting for your luggage again!
