wow Unterwegs, danke! This is great information.
The issue is that my company will only pay up to USD ~5500 and I have found something in between that is
EZE-MIA AA -BUSINESS
MIA-SFO- AA ECONOMY
SFO-MIA AA ECONOMY
MIA- FRA BA BUSINESS
FRA-EZE BA - BUSINESS
for usd 5600
The problem is that MIA-SFO-MIA in Economy in AA´s ageing 757 doesn´t look good...but the fares that you show are around USD 8000
I´ve also called United and they offer EZE-FRA-EZE (via IAD) for USD 4450.- . I could then do IAD-SFO-IAD for USD 400.- extra in Economy Plus...
Thanks again! Thanks marwanb
