Through 5/31/2012, when you transfer Amex Membership Rewards (MR) points to British Airways Avios, you will get 50% bonus.

Simply log into your MR account, select "Use Points" -> "...more Travel" -> "Transfer Points", find British Airways, and you will see every 1,000 MR points = 1,500 Avios.

Note that the transfer feature is only available on regular MR and MR First cards, not on MR Express cards. Confused by the level of MR cards?  Check out our featured review SPG vs. MR vs. UR.  We blogged about the devaluation of MR program in January and now certainly welcome Amex to come up with the new transfer offer to keep MR competitive, especially considering Chase has gained momentum with its aggressive campaign on its Ultimate Rewards program.

[Update 5/15/12] The offer has expired.

[Original Post 3/7/12] Capital One Venture 100K offer is coming back, but this time it is very different from last year's.  Last year in order to get 100K miles you just need to prove that you have at least 100K miles in your one single frequent flyer account.  And they are for both personal and business cards.  This year, you will get double miles on each dollar you spent in 2011 using one single personal travel credit card from other competitors, up to 100K miles.  You need to show that you spent $50K last year on a card such as Amex SPG to get the 100K offer from signing up a new Capital One Venture.  If you spent $20K you will only get 40K miles from Capital One.  They only take Year End Summary as the proof of spending.  You also need to spend $1,000 on your new Venture card to qualify.  The last thing is that Capital One is only giving away a total one billion miles so act fast if you are interested.

Even though the offer was not as good as last year's in general, some people may still be able to make full use of it.  For daily spending Capital One Venture gets you 2 miles per dollar spent.  Please note that even though Capital One markets their rewards as "miles", they are nowhere like the miles from frequent flyer programs - thinking them as 1 cent a piece will be appropriate.
