I am booking my summer vacation with aeroplan and I have the option of going with either lufthansa 747 to frankfurt or 777 to vienna with Austrian. Both would be in Business class from JFK but I don't know what would be better. I have read too many negative reviews with austrian but the new business class looks so good. I have also read the business lounge in Austria is nothing to brag home about. Anyone have any opinions on this matter?
