The money earned on the flight to the US, not to mention over international waters, is not covered under the foreign income exemption. Expect to pay income tax on that income regardless of your earning level. With the growing number of American pilots at EK, you can expect an audit at some time. The IRS is not so stupid not to realize an EK Captain makes more then $95,000 a year.
It is wise to invest in a tax attorney. Turbo tax won't cover most of these issues. When they come knocking, it isn't pleasant.
