I have a GVA-ATH Y flight in July and will have to wait 3 hours in ATH for friends travelling with other airlines. I am thinking about using miles to upgrade to biz for being able to have access to the lounge in ATH. I've never been to ATH. Here are my questions :
1. Do Swiss have its own lougne there or share it with other companies ?
2. Can I have access to it when arriving or is it only accessible when departing ?
Thanks in advance for your advice !
