Is there a way to get to Wintergrasp w/o buying Northrend flying?

I've been grinding honor for all my characters and the WG quests are great for honor every week. Is there a way to reach the WG base/flightpath w/o having to pay 500g for Northrend flying to turn the quests in? I have 7 or so 85's so I don't want to spend 500g x 5 (2 of my chars bought wotlk flying years ago).

Is there someway to reach the WG zone from Dragonblight? Appreciate any advice. Just trying to save me some gold.
