I spend every month about 500 euros to two business trips in a month, sometimes three for 750 euros, in flying from Tallinn to Oslo.
I often pay a ticket for return just in case. However, many times, I have to change my return date. I often just buy a new ticket two days before the traveling.
I am using at the moment Star Alliance for my traveling: SAS and Estonian Air.
I am at the moment still at the Basic level in Star Alliance. I have not done any business agreement with the airplane companies.
What is the best way to get cheap tickets two days before traveling?
