Gulf Air Frequent Flyer has introduced triple bonus miles on all First- and Business-Class travel through July 31.

A return flight from Bahrain to London would normally earn 12,616 miles in Business class and 18,924 miles in First class.

Through July 31, for the same trip, members will earn a full 37,848 miles — enough for a return Business-class ticket from Bahrain to the Middle East, Eastern Mediterranean and Karachi, or four one-class upgrades on those flights.

First-class mileage for return travel from Bahrain to London is an impressive 56,772 miles during the promotional period, which is enough for a return economy-class ticket from Bahrain to the Far East or two one-class upgrades on those flights.
