If weather and geography are the domains of Fate (and rightly so), then the conditions for flight which a Dragon 'just happens upon' when needed must stem from Luck's domains. Life is cheif among these and so I propose that Dragons are actually symbiotic creatures. The Dragon basic model can't do much, but different types (and maybe even individuals) differentiate physically in capability by effecting sybiosis with various exotic flora and/or fauna. A flying Dragon could therefore have a specific type of bacteria in it's gut, bloodstream, specialised bladder, etc (any or all of these could work) which create lighter-than-air gases, increasing boyancy and therefore allowing their perhaps rather puny wings to bare them aloft. The same idea could allow for photosynthesis, breath weapons, burrowing claws stronger than steel, etc. For a REALLY oblique comparison, look at Mr. Lucas' midichlorines (or however it's spelled)...
Keeps the Luck element in, they'd still likely need rare, unusual, or normally highly toxic substances to develop and maintain these 'cultures' of symbionts, but it's certainly an idea which offers considerable scope. Having written this, I seem to remember you mentioning a Dragon you already had ideas for which used symbiont lifeforms so why not make it the core of all Dragon's Luck control mechanic..?
