Husband and I are planning a trip in 18-24 months to Africa with four kids. We'll be traveling from New Orleans and will likely fly into So. Africa, Tanzania or Kenya (don't even know what our options are yet). From NO, there are several daily flights to Houston on Continental, also AA to Miami and Dallas and some to ATL on Delta. We have AMEX MR points (500k), Diners Points (300k), Continental/United Miles (400k), Delta (200k) and AA Miles ( 250k). We also each have recently acquired cards from both AMEX SPG and Chase Sapphire. Our spending on cc's is about $10k per month. Of course, I would like to get maximum value from our points/miles. I'm not expecting to book all of our tickets using points but would love to get 3 or 4 business seats. Do any of you experienced flyers have a wild guess as to where I might want to consolidate my cc spending? I know that it's a very inexact science at this point but I would like to at least make an educated guess. Any advice will be appreciated.
