The Domestic (was SR/LR) is designed to be run on the short hops for 15 to 20 years and then have the wingtip extensions and winglets installed to run out the rest of the airframe's life in long-haul service. This is actually a pretty nifty deal for those who run 747s on both long and short routes. My guess is that this mod would be performed during a heavy maintenance check (often a month or more in duration) and have the interior reconfigured at the same time. -- Terry email@example.com "Anyone who thinks they can hold the company responsible for what I say has more lawyers than sense."
