Ok, first it would be the past 5 seasons. Season 1 was no magic, so she couldn't have just flown out of storybrooke, any more than Rumple could.

as far as not revealing her wings and her ability to cross realms (which I agree does appear to be the case), She may take the approach of "When in Storybrooke, stay human". It may be simply that it is easier for her and the other fairies to interact with everyone else when they maintain their human form and size. And who knows, maybe Blue enjoys human company. Though, as we all know, the real reason is the Plot monster. They needed Blue to be able to do these things, so voila, she does them.

And TBF, when Hook showed up with the Hat, Blue panicked. and very few people do smart things in a state of panic.
