Be on the lookout for N334SW, the original "Shamu" flying whale.
It's still a killer whale, but has been partially repainted to account for the new "Canyon Blue" colors, mainly in the aft top fuselage and tailcone areas. The white "Southwest" lettering is now yellow.
The other "Shamus" (N507SW and N501SW) will also get the same revisions. N507SW is in the paint shop now.
Presumably, other "themed" aircraft, N352SW (Lone Star One) and the rest, will all get similar revisions.
