Or - since when?
Because they seem to add more restrictions every couple of years. As to the Q asked, and staying within the subject of commercially made folders, the answer would be - "none".
You may try another airline, but on some routes there is no "other airline".
You may try and load your carry-on bag up to 60 or 70 lbs, they seldom check its weight, at least in North America. I did this a few times because already had a hernia, and wouldn't do it now since got my hernia repaired.
Amtrack train is often a poor choice. Ticket in a coach car from, say, Seattle WA to San Diego CA costs the same as one-way air ticket, and this is sitting in "coach" car for 40 hours with hardly any sleep and eating expensive sh-t in train restaurant. No, thanks.
Greyhound bus is same bad as Amtrack train. It is usually faster (don't know why), yet about 30 hours for the same Seattle - San Diego route, and with less comfort than train. Besides, Greyhound has stricter luggage rules than Amtrack.
Shipping things ahead - may be, it depends where. On international flights, including "sort of" international leg from Canada to US or Mexico, it may be cheaper to pay airline overweight charges than shipping. Not to mention timing (low-cost shipping has unpredictable delivery time), and inconvenience and costs related to spending half a day or full day and night in town where you pick it up, before taking a bus or cab to your real destination. And there are often customs dues on international shipments, even when it's some old stuff.
And there is nothing else - again, within the subject of commercial folders. Beyond the subject of folders - yes, there are options. You might go for inflatables - those are not folders; very little weight savings (if any) with boat of same size, though they are less bulky in bag. Helios will weigh less than much larger Klepper, but not less than comparable size Citibot. Don't get me wrong - there are paddling situations where inflatable is better than a folder. But, unless you need and like inflatable for reasons other than lower airline charges - it's not worth getting. Airlines are concerned more about overweight than oversize - there is enough room in cargo hold because not everyone on board is a die-hard folding kayaker, but every pound of weight means extra fuel, and the industry is already struggling with high fuel costs. Or you can get a vacation shack or an old trailer in some place where you fly to every winter anyway, and a dugout canoe, and fly with a fishing pole and few clothes.
