The Plaza in Seoul will launch its frequent flier mileage program from September in partnership with Delta Airlines. The hotel said it has become the world’s first independent hotel to forge a mileage partnership with Delta Airlines. All SkyMiles members of the air carrier can benefit from a “Double Mileage Accrual Promotion” for three months from September to November. SkyMiles members who are eligible for 300-mile accreditation for one night’s stay will receive 600 miles in mileage during the promotion. For inquiries, call the hotel at (02) 310-7710.
