100,000 AAdvantage miles is enough to take 4 round trip flights with American Airlines within the 48 contiguous states. To get these miles, all you need are two cards (and a little luck).
Citi offers the AAdvantage Platinum ($95 waived annual fee) and AAdvantage Executive ($450 annual fee) World Elite credit cards which typically have a sign-up bonus of 50,000 miles after $3,000 spent in the first 3 months.
Sometimes people get sign-up offers mailed or emailed to them for 60,000 miles and then ask Citi to match this offer because they got it just after signing up for the 50,000 miles offer. This worked for me and I was very happy Citi was generous.
Now, at this point you might be thinking I’m suggesting you sign up for the two Citi cards and pay over $500 in annual fees. But I’m not. I’d recommend the AA Platinum card, because you can only get 1 sign-up bonus for each point family (1 AAdvantage + 1 Hilton Honors + 1 ThankYou Point) every 24 months.
The second card comes from Barclaycard, a British bank with a US suite of credit cards.
The AAdvantage Aviator Red was recently brought back and offers 40,000 AAdvantage miles after your first purchase. Yes, this means an apple from the supermarket will earn you 1 round trip and 1 one-way flights.
The catch to this card, however, is the $95 annual fee is not waived the first year but you get the same benefits from this card as you do from the Citi AAdvantage Platinum card.
Both cards offer no foreign transaction fees, if you plan to travel internationally, but the Aviator Red has Chip + PIN functionality, something the AA Platinum does not.
