Are all American Express cards the same? A card’s a card, right? Why do some cards have a credit limit and some don’t?

Most people don’t give too much thought to these questions, but it’s important to understand the difference because credit cards with and without a spending limit are two very different financial tools.

Now is a special time to earn American Airlines miles.

The personal American Airlines credit card is offering 50,000 bonus miles after spending $3,000 in the first three months.
The business American Airlines credit card is offering another 50,000 bonus miles after spending $3,000 in the first three months.

The personal deal has been the official offer since late October and the business deal since late November, so they've been around for three and two months respectively.

How much longer can we expect these amazing deals to last?

First, a quick word on why the deals

First, a quick word on why the deals

I get almost all my miles from credit cards.

I rarely fly a paid flight on an airline that offers miles (and when I do, it's usually not paid by me)
I don't do much online shopping through airline portals
My dining program earnings are minimal

For me, it starts and ends with sign up bonuses and category bonuses on credit cards.
