Valid for new bookings, flights which are cancelled and then rebooked do not qualify. A Qualifying Flight is either a single sector direct flight from San Diego to London Heathrow or a single sector direct flight from London Heathrow to San Diego that is operated by British Airways. Double miles may be earned in any cabin or booking class which is eligible for base BA Miles. Code share flights operated by any of BA’s partner airlines are not eligible for this promotion. Members must quote their Executive Club membership number when booking their Qualifying Flights and again at check-in for each sector flown during the Promotional Period. Failure to do this will result in Members not being credited the bonus BA Miles applicable for travel under this promotion. British Airways (“BA”) reserves the right to verify the eligibility of Members. A sector is a single eligible flight between San Diego and London Heathrow with no scheduled change of aircraft. A round-trip flight counts as 2 sectors. The following are not Qualifying Flights and this promotion cannot be used in conjunction with any offer, promotion, or deal including: (i) redemption bookings; (ii) travel agent discounted fares, child/infant fares or senior citizen fares (iii) bookings made with vouchers or coupons (e.g. shareholder’s discount coupon). Members who change their travel arrangements after the date of booking will not be eligible for this promotion unless their revised travel arrangements also constitute the necessary Qualifying Flights. The double BA Miles are calculated on base BA Miles earned between SAN and LHR only. Cabin and Tier bonuses will not be doubled as part of this promotion. All Bonus BA Miles earned under this promotion will be credited automatically to Members’ accounts after completion of each Qualifying Flight.
