They will repaint, at the most one L-1011. Like you said, the last one will be retired next year. I think that they schedule the retirement of each aircraft according to when the next D-check is due. It is only during a D-check that an aircraft is repainted, isn't it? Remember TWA with their L-1011's? Only one of them was painted in the new livery. TWA introduced its new livery in 1995 and the last L-1011 was retired in 1997. Delta will do the same, retire the last L-1011 one or two years after the latest livery was introduced.
