Ok, I understand...Really wasn't sure of the difference between a charge and credit card...but duh, I get it now
I know you have mentioned you fly AA a lot. Are there other uses for Delta points if you never really fly Delta? I'd like to look at Hawaii for my family in a couple of years and Tahiti for just dh & I in 3 years. Should I consider some of these airline cards even though they don't seem useful currently? That is one reason I want the IHG card.
A charge card is one that the balance must be paid in full every month. A credit card allows you to roll your balance after a minimum payment. Despite the difference, a good travel hacker treats all credit cards like a charge card or debit card to avoid ever paying interest or spending money they don't have.
I do fly AA/One World a lot because Miami is an AA hub. The majority of my choices for flights are AA and their partners. I had cards from all the legacy carriers pre AA/US Air merger except Delta. I did not get any Delta cards until last year when they offered a historically high bonus of 70k on 2 of their cards. Prior to that I'd always see 35k offers which aren't worth the hassle to me. Delta miles don't expire which is good. Unfortunately, you cannot use the miles to book in first on partners only on their metal. They don't publish their award chart either. Given the choice between chasing variable points like UR, MR, TY and Delta Sky Pesos I'd stick with the variable points. Once in a while though you will find some use for them which is why I picked them up. Unless you are stuck in a Delta hub, I wouldn't bother. As a backup plan for a specific award you are planning or to diversify the miles/points portfolio when they have another great sign up bonus, sure why not.
Yes, airline cards are crucial to the flights and are useful currency when planning something specific. DH and I blow through several hundred thousand AA miles on trips every year. We use AA miles way more than we use UR, MR or TY points. That said, I don't put spend on the AA card. My suggestion for Hawaii would be to determine what your best flight options are going to be from your home airport to start planning what airline card you may want to use. If you recall our Hawaii trip wound up as a combination of miles and paying with airline gift cards to get DH and I there and back. Granted we were looking for lie flat seats so my choices were more limited. None the less, I started with searching MIA - HNL on Google flights and Momondo. Sure enough the majority of the flights were AA so I knew that I would likely be using AA miles. Once you know what airline you are probably going to fly then join that airline's frequent flyer program and check to see how many miles it will take to get your flights. Do a mock booking search for as far out as possible and see what pops up. That should give you a good idea.
Just on a pension. debt which so much families have in Australia is not something I want or need
Plenty of families in America also have debt and I can't imagine that anyone wants, much less needs debt. That is not what this thread is about. Those who are able to pay their balances in full each month and won't spend money that they don't have are the people who can effectively play this game. I have to put gas in my car, I have to pay my utilities, I have to eat and every month I am going to spend money on something whether that something is a want or a necessity. If I have to spend it anyhow, then I sure am not going to use cash or a debit card because I will get nothing in return. I will fill up my tank and pay with a credit card that gives me bonus points for using it at a gas station. Then, I will pay that balance in full. If I buy groceries, I will pay for them using a credit cards that gives me bonus points for using it at a grocery store and pay my balance in full. When I pay for my cell phone bill, I pay using a credit card that gives me bonus points for using it on cell phone bills and pay my balance in full. All of these bonus points add up and then I have points to use as cash back if I choose (which I don't) or points to transfer to airlines and hotels or pay for travel related purchases.
Some of us will get extra money we didn't have throughout the year and put it towards savings or a special treat with this hobby. Some of us are able to minimize their travel expenses and take a nicer vacation that doesn't hit the budget as hard. Some of us are able to travel in a manner we would never be able to afford or wouldn't choose to pay to do with the points and miles. I didn't want you to be under the impression that everyone here is going into debt or that this was a thread advocating something like that.
