Looks like N77295, a GUM based 737, was ferried to Cleveland last week. Does anyone know if this is due to a routine cycling of aircraft into and out of the GUM fleet, or would it be for some type of maintenance? Surprised at the 8+ hour flight it took from GUM-HNL which is ~1.5 hours longer in duration than normal for the route. I'm amazed that it has the legs to make the westbound trip HNL-GUM if the eastbound was over 8 hours!
