I looked at the hard case. The issue I had with it was it was very heavy at over 7kg. Along with a Brompton you're looking at going on 20kg which doesn't leave much spare for the rest of your stuff if you're looking at a standard 23kg limit.
If you have free sports gear (increasingly rare), executive club membership so you get two bags or you're happy flying with hand luggage for everything else it shouldn't be an issue but it's something to consider.
Folding case is heavier than the hard case, new padded travel bag is 3.2kg. Thing is, you’ve seen how luggage is stacked - do you really want your Brompton in its side under 500kg of other baggage?
