My mom booked a cheap r/t SFO-TLV-SFO on the nonstops. The $598 fuel surcharge far eclipses the nominal "airfare".

When I view her itinerary, on United.com, it seems to credit the entire surcharge to the return leg when computing her estimated mileage earnings. Am wondering if it's likely to do that when computing actual earnings post-flight (if so I might advise her to credit the outbound to a different program)?
