I suppose the benefits of being a EuroBonus member are as follows: You'll get nothing and like it. Apart from being able to accrue miles with SAS and other *A airlines and then hopefully being able to spend them on bonus flights or upgrades, are there any benefits of being an EuroBonus member? Perhaps you get to save your bookings on the website under my bookings, but I think there is also an option to create an account which specifically does not enroll into EuroBonus.
