The Swiss Business lounge in Geneva is a mid-sized lounge, appropriate for the size of airport it is located. I can’t really speak for those who always use the lounge at peak hours, but in the dozen times I have been here I have always found a spot to sit on.
The lounge doesn’t have shower room like the one in Zurich but then again Geneva is not an Intercontinental airport hub. The food lounge generally has fruits, bread and cheese and it has sometimes small hot meals.
Access to the lounge per Swiss Airlines:
“First Class SWISS, Lufthansa und Star Alliance, HON Circle, Miles & More Senator, Business Class SWISS, Lufthansa und Star Alliance, Miles & More Frequent Traveller, Star Alliance Gold”
You can also use Priority club here.
The lounge is open from 5:30 AM till 10:30PM and it is located one floor above the main departure hall inside GVa terminal.
