advice on maximising benefits
 

New to the site and looking for advice on maximising miles and points on regularly commuting flights between london and barcelona. I book via internet BA using my BA amex 6 to 8 weeks in advance. I earn air miles but not exec poinyts on the tarif. Alse feel I should be able to benefit more when we travel long haul usaully 3 times a year. Advice and guidance appreciated. Thanks
