Singapore Airlines offers very good award availability to its own members, but not very good availability to partners. I’ve written about excellent first class award space Los Angeles – Tokyo and great business class space Houston – Manchester.

If you want to fly long haul premium cabin awards with Singapore, you need to use Singapore’s own miles. Chase, American Express, and Citi points all transfer to Singapore Airlines Krisflyer.

• Ink Business Preferred℠ Credit Card has an 80,000 point signup bonus after $5000 spend within 3 months. It earns 3 points per dollar on travel — that’s airlines, hotels, rental cars, tolls, even Uber — and 3 points per dollar on shipping and advertising on social media and search engines, so great for anyone who advertises on Facebook or Twitter, or who spends money advertising with Google.

• Chase Sapphire Preferred Card lets you earn 50,000 bonus points after you spend $4,000 on purchases in the first 3 months from account opening. With a $0 annual fee the first year, then $95, I suggest that as the number on card to get started with in miles and points. The card earns two points on travel and dining at restaurants and 1 point per dollar spent on all other purchases worldwide.

• Business Gold Rewards Card from American Express OPEN offers 50,000 Membership Rewards points after $5,000 spend on purchases with the card within your first 3 months of cardmembership. (Offer expired)

• Citi ThankYou^® Premier Card is offering a 50,000 point signup bonus after $4000 in purchases on the card within your first 3 months of account opening. It has a $0 annual fee the first year, $95 thereafter. And it’s a stronger points-earning card than the $450 annual fee Citi Prestige Card since it doesn’t just earn triple points on air and hotel (Prestige) but on all travel (such as gas).

Availability for Los Angeles – Seoul is excellent starting in July for two passengers in business class. Here’s September availability in both directions:

This flight is operated by a Boeing 777-300ER which is configured with a 2-row mini-cabin behind first class, and then a galley separating it from the rest of business. Many people prefer the relative privacy of this mini-cabin.

Here’s a look at the business class suite. With a four-across configuration, like in first class, the seats are incredible wide and they are also relatively private. I like the bulkhead seats which had more space. The only knock on the seat is that while fully flat with direct aisle access you generally angle your body to sleep rather than laying parallel to the aisle.

Singapore charges 85,000 miles each way for Los Angeles – Seoul in business, and no longer adds fuel surcharges to awards on their own Singapore Airlines flights.
