I'd love to get a quick 17K EQM's to get to Platinum, and PHL-DFW-LHR-DFW-PHL would do it with the 50% bonus on the business class fare. But the DFW-LHR segments alone are $536 outbound, $1183 return and $292 in taxes, putting the total TATL segment over $2K all in. That's before buying the PHL-DFW that I would need to get me over the 17K requirement. Oh well, I'll be falling back to Gold next year.
