Why in the world would I want to do that? By continually taking out credit cards for their signup bonuses and paying off all balances every month without fail, I earn so many airline points that I can take two international business/first class trips a year for virtually no cost.
I'm going to Vietnam and Thailand in January, flying Japan Airlines first class on the way out and Cathay Pacific first class on the way back. Total cost: 145,000 Alaska Airlines points and $130 in fees. Cost of ticket if paid for entirely in cash: $19875.
I do the same, but economy.
Chase sapphire reserve is the best credit card ever for me btw
