Thanks to the Frugal Travel Guy, here's a link to the British Airways 100K Visa offer – back on, but who knows for how long??  If you're interested, check it out now!

50K at sign up, 50K when you spend $2K in the first 90 days.  100K will get you 2 roundtrip tickets to Zone 1 (England, Ireland, etc.) from the U.S.   Better yet, have your wife or husband sign up at the same time and combine your miles as a Household Account.
