I have, and the question always come down to "home base" and where your "financial ties" are... whether the flying is foreign or not (or even domestic), if one is based overseas, and is entirely tied to their presence overseas would (in the legitimate tax professional's view) allow one to qualify for the FEIE based on "bonafide residence" (and negate the need to show 330 days overseas), meaning the time spent overseas wouldn't even be a question due to the actual base being overseas. With WG's language the "needs a US address for tax reasons" has me questioning how WG is structuring their basing/tax structure. That's not a dig at WG, but rather a genuine point of inquiry since I've been getting hosed by the IRS with the concept that my "home base" is a city in the US I have not step foot in for over 20 years. If WG pilots are able to quality for FEIE based on bonafide residence that is a potentially huge advantage in yearly net pay (around 30k-35k).
