Singapore Airlines is consistently rated the world's best airline — and for Brompton riders it is also one of the most generous for bike transport. Bicycles are included within the standard checked baggage allowance at no extra charge, provided total weight and dimensions stay within your fare's limits. For a Brompton in a B&W case this is almost always achievable. For riders connecting to Japan, Australia or Europe via Singapore, SQ offers the most civilised way to travel with a folding bike.
