With budget airlines like RyanAir, you pay to take any luggage in the hold, but hand luggage is still free. So the cheapest way to fly is to only take hand luggage. There’s normally a 10kg limit on this though — so what are the biggest, lightest bags you can take with you on the plane?

UK consumer site Money Saving Expert has an interesting forum thread to help you choose the best bags / cases for hand luggage.
