As UL suffers poor loads during off peak periods, wouldn't it be better to combine FRA/CDG instead of FRA/MXP/FCO ?
There's good loads to MLE from MXP/FCO so shouldn't those flights be going and returning through MLE ? Don't know of any Italians who would like to visit SL for their vacations whereas MLE has always attracted them in large numbers. Food for thought.......
