I learned SO much from taking the free course at
www.10xtravel.com, along with reading
www.thepointsguy.com. The course walks you through step by step what to do and has a "cards list" to follow in order when first starting out.
They are very pro-Chase but I also rack up AMEX MRs via some of their cards and
www.rakuten.com because I am a Delta snob when flying from LAX, and Chase doesn't transfer out to Delta.
Chase codes
DVC as travel, so our recent direct purchase netted us almost 90,000 Chase URs!
Not to hijack, but I agree - this amount of air travel would not be realistic for us without credit card rewards.
