Sooo happy to have caught this one! Note the small COA maintenance facility at HOU in the background.

Former N83SW of Southwest Airlines. Most probably operating an NHL sports charter flight for the San Jose Sharks. Owned by Ameristar / Sierra American Corporation.

This former Southwest Airlines 737 was bought by Royal Aviation March 6, 2001, shortly after their take over by Canada 3000. Unfortunately, after the temporary cessation of all airline traffic after the September 2001 World Trade Center attack and subsequent downturn in bookings, Canada 3000 did not have enough cash on hand to survive and declared bankruptcy November 8, 2001. This aircraft ended it's days with Avior Airlines as YV-1576. It was withdrawn and stored at Barcelona, Venezuela in August 2013.
