<prompt> Human: I just applied for this card, after starting a thread a couple weeks ago about good credit cards that offer rewards for flights. What is your personal experience using this card redeeming the rewards?  <response>: Best plan of action:1. Sign up for the Sapphire Preferred for 40k bonus miles AFAIK, the United Explorer 50k bonus if you have a United account with miles in it and the Chase Freedom 30k bonus. Find the links at flyertalk.com2. The miles are transferable: Freedom - Sapphire - United, so together youll have 120k miles.3. Book an international round trip business class flight for 100k at united.com but preferably with a partner airline like Lufthansa, SWISS or Singapore Airlines. These go for thousands of dollars, so youll get at least 5 cents per mile instead of the measly 1-2 cpm youll get for Economy class travel. Or earn a 12.5k more miles and redeem for a round trip first class flight. This should be not that hard if you play your cards right and take advantage of the Freedoms 5 bonuses. You might even consider opening a Chase checking account for another 10 miles per transaction. When online shopping, use the Ultimate Rewards mall links to get extra miles e.g. 2 miles at Travelocity.com.If youre short on miles, you can book a one way First Class award for 67.5k. Be smart and take advantage of the free stopover in the US. If you live on the west coast, you can book Singapore - San Francisco - New York for 67.5k. The stopover can be months long, so essentially youll get a one way from Singapore and a one way to NY for the price of one flight.If you dont care about which cabin you fly in, Economy award flights are the better option of course, though some people see this as a waste. For short domestic flights that are unusually expensive, you can try to transfer the miles to British Airways and book flights on American Airlines. This is more economical because BA calculates the cost for award flights by distance.
