It doesn't look as if you have a cart or a beast of burden with you, so I'd better send you back only with what you can carry. If you've spoken with Skymaster Sunwing at Tranquillien, then you should get this to Quartermaster Lymel as soon as possible by flying back.
Take these goods for final inspection to Skymistress Gloaming just outside Silvermoon City's Shepherd's Gate.
Wow, that box of goods you have there looks heavy! You want to load that up on one of my flying beauties?
Back down to Tranquillien in the Ghostlands, then? Sure, I can get you there fast!
