The Capital One Spark Miles Business Card is for a limited time, offering UP TO 200,000 BONUS SPARK MILES (previously 50,000). Yes, you read that right, but the spend requirement is pretty steep. You can earn a bonus of 50,000 miles when you spend $5,000 in the first 3 months and 150,000 miles when you spend $50,000 in the first 6 months of opening your account once you spend $5,000 on purchases within the first 3 months from account opening. If you can do that, I would jump at this offer. I have never seen an offer for 200,000 rewards.
Recall, with the card there is $0 Introductory Annual Fee the first year, then $95. You earn unlimited 2X miles on every purchase. You pay no foreign transaction fees when you use your card on purchases made outside the United States. You can redeem your miles using the purchase eraser feature and as of the other day, come December, you will be able to transfer your Cap One Spark Miles to 12 airline partners.
If you can swing it, this 200,000 bonus is worth at least $2,000 and possibly even more if you use the new transfer feature. Capital One Spark Miles are flexible rewards. However, you need excellent credit to be approved. Good luck if you go for it!
