Okay, so this one needs a bit more effort, but it is a multi-award-winning lounge, combining Belgian hospitality (think beer, chocolate, TinTin and the Smurfs) with Japanese philosophy and design (think super polite staff, stylish décor, and even the plants being chic). It offers everything you want from a lounge: showers, sleeping pods, meeting areas, massage chairs, great food and drink, a kids’ play area (with said Smurfs), all in an enormous space, with a separate VIP area for those flying in premier class. The lounge itself is worth flying on Brussels Airlines, or any other Star Alliance (such as United) flight.
How to gain access: Passengers on Brussels Airlines or Star Alliance, as well as Star Alliance Gold Members. Note that the lounge is closed on Monday, Thursday, and Friday (at least to economy passengers)
Cost: Free to premium flyers and Star Alliance Gold cardholders, but economy passengers of Brussels Airlines (or Star Alliance members) can pay for access online, from Euro 49 ($57).
Location: Terminal A, Level 2, near Gate A42.
