Further info: Sporty's Pilot shop, Travel John (pack of three) $6.50. Description: Absorbent pouch turns urine into gel instantly while destroying bacteria and odor. Specially designed collar works for men, women and children; spill guard prevents back flow during use. Convenient, sanitary and compact, the Travel John is easy to use while sitting or standing. Will not leak, even if punctured.
Seems like a viable alternative.
If your bladder control is iffy, seems there are two alternatives: 1)Don't fly. 2) buy piddle packs and always carry them onboard with you. Would be embarrassing but certainly better than what happened the unfortunate fellow in the headline.
