For my next churn I am looking at the Chase Marriott, the TD Aeroplan Infinite and the Amex SPG. Fingers crossed, the 3 will go through in 1 day.

Looking for input from experienced churners here on the forum:

- should I do this as soon as credit score goes up, or wait a few days (how many) after score increase?

- should I do them in a particular order?

- is there a difference in success rate between application sites? (RFD, GCR, direct with institution)

- if an application gets denied on one site, proceed to resubmit on the other site or let be for 90 days?
