True... For LAX-JFK the norm is $3000-3500... I think DL's fares for J from SFO/LAX-JFK is a rip-off, no wonder they are having a hard time selling seats...

My father's company pays for his trips, my mom goes with him sometimes [when the trip is more of a vacation rather than work related], and she pays for her own plane ticket... However, when we were looking for homes in CA back then, the company paid for both of my parents to fly and look for homes before my father agreed to relocate to the Bay Area... I guess it all varies depending on individual situations...
