Nice story!
AA 51 on Sunday might have been a mileage-run haven. I was in 12J, having arrived at LGW a few hours before on AA174 from RDU...my seatmate was a FT 'er from DFW who had flown in on Friday...and I think there was another person in J collecting miles, IIRC.
But the retired teacher from Oakland apparently tops us all...
Aloha.
