This is a bit of a random post, but I have failed to see any photo's of the newly refurbished and enlarged executive lounge. As nothing shows on the airports website.
While I appreciate these are promotional photos, came across this lounge booking website and it looks a lovely place to be, compared to how cramped and unimpressive it was before. It looks on-par with some of the best lounges about.
