If you're talking about the one Clary sees a few times throughout the series (starting in City of Bones atop the Hotel Dumort) that rune wasn't for flying it was what she used to trap Jace's Heavenly Fire in the weapon during CoHF. I don't think there are any runes to make you fly, though maybe Clary could make one.
I still can't believe that she first saw that rune when the actual need for it was still months away.
And I'd like to see if she can make a rune to make you fly. That would be neat. :)
/\ Maybe the flying rune would actually look like wings. :)
Hwy guys thx 4 answering i didnt rember i had a wikia account till a few days ago i was the 1 who posted this thx so much ! :)
YEah that would be toats awsome
I think op was talking about the winged rune seen in the codex, and also on the main Runes page (http://shadowhunters.wikia.com/wiki/Runes). The one you're describing is a different rune, "a shape like two wings joined by a single bar"
