If you bank miles with a flexible-points credit card, consider transferring them into foreign-airline loyalty programs, which can have bigger payoffs than their domestic counterparts. Three worth keeping in mind:
British Airways: B.A. offers great value on short-haul award tickets: business-class seats on flights of up to 650 miles cost just 9,000 Avios points, one-way. Compatible with: American Express Membership Rewards, Chase Ultimate Rewards, Starwood Preferred Guest.
Korean Air: Travelers can use Korean’s Skypass miles to get first-class seats on Korean Air and most other members of the SkyTeam alliance—a benefit not available to Delta SkyMiles holders. Compatible with: Chase Ultimate Rewards.
Singapore Airlines: The carrier offers business-class awards on certain routes exclusively to members of its KrisFlyer loyalty program. Compatible with: American Express Membership Rewards, Citi ThankYou Rewards, Chase Ultimate Rewards, Starwood Preferred Guest.
