That is a Delta requirement not a MEL requirement. Delta feels that the APU is safety backup system. If the jet is in the US and it can be worked on then they want it fixed before it goes across the pond. They allow one flight home from overseas if it is inop per the MEL. USAIR does not have the same APU requirement and can dispatch without it on 120 minute ETOPS flights.
