On October 17th, there was this flight listed on FlightAware.com bound for PAE, and the aircraft listed as a 737-700. I could not find an airline attached to the code VBH. According to one of our readers walking along Lagoon Drive, he noticed it was a Virgin Blue 737-700. There have been reports that Southwest Airlines has purchased some of VIrgin Blue's 737-700s. The aircraft are flown to PAE for interior modifications and re-painting.
