1)whats the point in accumulating tons of points/miles if your just going to cancel the card? aren't the point/miles getting cancelld if you don't have the credit card?
2) a guy could have a million points but they'r all from different programs(UR, AMEX membership, citi etc.) are they all , or any of them , combineable to be worth something, or do you have to use them in each program separately?
1) As per
http://www.dansdeals.com/archives/53213Q: Won’t I lose my points if I close a card?
A: Airline or hotel credit cards accumulate points in your airline or hotel loyalty account.
Those points remain there even if the card is no longer active, and are subject to the normal expiration dates that you can find in this post.
You will not instantly lose any earned Hyatt/Starwood/American/BA/Delta/Southwest/United/etc. points just for closing their credit card. Some representatives use scare tactics and say your points or tickets will be lost if you cancel the card but it’s just misinformation. The only thing you will lose are points earned from spending since your last statement closed, so you may want to wait for your next statement to close before closing a card.
Proprietary credit card point programs (American Express Membership Rewards, Barclays Rewards, Citi ThankYou Points, Chase Ultimate Rewards) do not expire as long as you keep at least one card open that is enrolled in their respective program.
2) Points in Proprietary programs under the right circumstances can be transfered to airline Frequent flyer programs for you to use to book tickets. There are several FF programs that participate with more than one proprietary programs. (for example both UR and MR can transfer to BA)
