Accumulating credit card points for long periods is generally unwise because rewards programs frequently devalue their points.

“Every single one of these programs continually devalues year-over-year at a much worse rate than the US dollar is is devaluing. And so holding points is a generally terrible idea. You should you should earn them and burn people say.”

Internal train travel in Japan should be planned carefully to avoid excessive costs.

“It's like 30K. Yeah. The speed train ones are expensive, yeah. >> It's like it's a four-hour train and it'll be 30,000 rupees for two people. >> Yeah, but that train goes real fast. >> Real fast, yeah. >> So internal transport does kill you in Japan if you're not smart about it, not earning some poi”

One should carefully calculate the value of points versus cash costs when deciding whether to use travel rewards for flights.

“if it's going to be 80,000 points round trip, but the flight only costs $1,000 or $1,200, well, that's under 1.5 cents per point. In which case, that would make very little sense to do.”
