Update 5/6/11: The 100k mile card promotion is now expired. The information on using British Airways miles should still be accurate.
First, a quick reminder that the British Airways 100,000 mile promotion mentioned previously is scheduled to expire in less than two weeks on May 6th. To recap, the
Chase British Airways Visa Signature card (expired) is offering 50,000 British Airways (BA) Executive Club miles for new cardmembers with first purchase, and another 50,000 BA miles after spending $2,500 within 3 months of opening, for a total of 100,000 miles.
There are many options on how to spend these points, for example we spent them on business class tickets to London and Rome. But to show the basic value of this offer, I looked into how to use British Airways miles to book award travel on American Airlines, their partner in the US. If American Airlines has a domestic award seat available in their “MileSAAver” category, then in general you can book it with British Air miles. A flight within the continental US costs 25,000 BA miles plus $5, with no fuel surcharges. (Other combinations of less miles and more cash are available, see below.)
If your flight is a direct flight with no stopovers, you can search and book an award online at BritishAirways.com. On the site, go to “Spending BA Miles” and then “Book with partner airlines” and then “Make a reward booking”. They always try to find BA flights first, but once you search for domestic flights, you’ll see this option to include partner airlines.
Here is a screenshot of an award I found from Los Angeles to Dallas/Ft. Worth for 25,000 miles + $5:
Note that I can see the availability even if I don’t have enough miles to actually book it yet. Alternatively, you can book an American Airlines flight from the continental US to Hawaii for 35,000 + $5. Here is an award I found from Los Angeles to Honolulu during the summer for that amount:
Of course, it’s better if you can book ahead of time for the best availability. If your flight has a stopover, you might want to look for award availability on the American Airlines website first and then call British Airways to book the award flight. Since you can’t find the airfare online through their search system, you can try asking them to waive their phone booking fee. Thus, with the 100,000 miles from this offer (plus $20 in fees), you could by four domestic round-trip tickets in the lower 48, or nearly three round trip tickets to Hawaii.
