A former Aloha Airlines 737-76N, N743AL (c/n 28654, l/n 986), that was leased from GECAS, has been acquired by Southwest Airlines, and will be registered as N7811F (f/n 7811). This is one of two former Air Berlin 737-700s that Southwest is picking up. Both are currently at BFI, in its former carrier's livery, awaiting their new livery.
After it's three-year-plus stint with Aloha (January 2002 - December 2005), this 737-76N was leased to Air Berlin as D-ABBS from December 2005 to March 2013.
N743AL is seen above in this August 2005 photo, seconds from touching down on Runway 26R, completing another west coast run. This would be one more ETOPS 737-700 in the Southwest fleet.
Mahalo to Joe G. Walker for the information.
