This would be much more challenging for *A!
I tried the www.oneworld.com and www.aa.com interactive map.Both seemed pretty much useless.
You would be able to add MIA-RDU-IAD instead of just MIA-YYZ.
Where do you see an AA flight RDU-IAD?
Only US and Canada? cause MEX gives you a lot more options
MCI/STL/MSY
ORD-ATL is also Codeshare
ORD-ATL is on American Eagle - is that only redeemable on AA but not with any other OW miles?Either way you are right that TPA/MCO is probably a better option
I was just going to point out that on ARM the American Eagle flights do not show up when filtered by OW.
Sorry, I meant RDU-DCA.
