IT IS a love affair that happens once every 19 years. This year, Valentine's Day will 'tie the knot' with the Lantern Festival on February 14. To mark this extraordinary event, the MTRC has created a pack of two Be My Valentine souvenir tickets. The souvenir ticket pack is now available at all MTR ticket offices. Priced at $50, each ticket pack comprises two souvenir tickets, a Valentine Card ticket pouch, as well as a coupon which entitles the holder to dedicate a song to his/her lover in the Commercial Radio 2 programme. The holder of each ticket can make two MTR journeys regardless of the origin or destination and each ticket is valid for one month. Each purchase is limited to two packs. The souvenir tickets will be returned to the passengers after the second ride.
