Just wanted to advise users that Ive had no issues with the spray/pump. Ive been onmany flights but always carryon my deodorant which the perfect size and also handy to have available on long journeys. I carry a spare cap and keep the bottle in a ziplock, just incase. In hot and or tropical situations, I may need two applications. I would say that it doesn't have the staying power of the rosewood based product, but still the best!
