First time booking AA award travel after having 75000 miles drop into our accounts from the Citiadvantage CC.
Would like the wisdom of the board before I book this 50,000 point award ticket:

AA Flight 1244 STI MIA Economy
AA Flight 68 MIA to MAD
IB 358 Flight 1150 to ALC
IB 359 Flight 53
AA 53 MAD to MIA
AA 979 MIA to POP AA

Would booking IB vs AA make the trip more comfortable?
Any other ideas or more stops to take?
Taxes run $152 per ticket

Thanks in advance
