Assume Mathew's earnings per year are more than 30,000 euros. He pays now for lounges: about 30 euros for one visit. So he pays now about 500 euros every year for lounges. He needs to travel only between Tallinn, Oslo and Helsinki.
Are there any cheaper methods to stay in lounges like by some bonus programs or Credit cards?
I am now thinking about a Diners Club International credit card, but I am not sure whether it is the best solution for my situation.
