British Airways is offering a credit card that provides 50,000 free Avios (miles) upon approval. You simply have to be approved for the credit card and spend $2000 (on anything) within the first three months of account opening. There is also no annual fee on this credit card. Click here to apply.
This is great for use toward an international airfare, as you should be able to cover at least one-way on a round-trip ticket for $0 through these free miles.
If you use this in conjunction with American Airlines miles (e.g. bonus miles), you can easily get an entire international round-trip airfare for free. Business class and/or first class airfares are even possible.
Steps:
1. Apply for the credit card at the above link.
2. Spend $2000 (on anything) within three months of account opening.
3. Receive 50,000 free Avios (miles) from British Airways.
4. Redeem this for a free airfare.
5. No annual fee is charged for the first year.
