Miles & More (Lufthansa's Frequent Flyer Program) is giving away a free Regus Businessworld Gold membership.
If you are not a Miles & More member you can sign up here for free. The link was originally targeted for a Senator (Top Tier at LH) status but worked for me – already got my confirmation.
The Gold BusinessWorld membership get's you a comfy seat and free WiFi and tea/coffee in any of the 1,500 Regus centers worldwide. It's not that easy to find the locations on the Regus website so I'm usually using Google Maps.
The lounges are downtown and I have never seen one at an airport. Do they them?
Some are fantastic like the Regus Sydney downtown, the Regus in the Petronas Towers, Kuala Lumpur, Malaysia or the ubercool Regus center in Mayfair, London. Some are pretty mediocre and cramped like the Regus in Auckland, NZ downtown. But they usually have fast WiFi and it's much quieter than a coffee shop.
