No, they are not the same, Vancouver+ it's a scenery for the city, which has been made by another developer ( John Patch ) that sadly passed away this year, so I don't think it's on sale anymore.
We do a scenery for the airport, and many users used the two together, but they are entirely separate products.
Also, you won't find any downloads for any of our products, even on Simmarket. They download link is always from our own website, regardless which site you use to purchase the scenery.
