No automatic reimbursement for baggage when bundled with airfare purchase. That's what the AMEX rep told me when I switched to Spirit this year. So I made separate purchases (although somewhat more expensive for bags that way) as follows and did get auto reimbursement for the baggage fee ($70) and the $9 club fee ($59.95) on Aspire card after 4 days:
:
1st transaction: $9 club $59.95 (coded Spirit.com/Misc Tax & Fees)
2nd transaction: Ticket purchase: $425 (coded Spirit Air South Florida, FL/ Flights from ....)
3rd transaction: Baggage fee $70 (coded Spirit Air South Florida / Misc Tax & Fees)
Trip insurance $37 (coded Spirit Travel Guard Stevens Pt., WI)
