With limited exceptions, Kosher is Halal (though obviously the reverse isn't necessarily true).
Most orders of KSML by Muslims are probably based on the understanding that it will be a meal that more certainly excludes pig products; and indeed many airlines' MSMLs are really nothing but a standard meal from the common catering company where the standard meal is taken to exclude pig products and noted as MSML but otherwise ordinary -- speaking of airlines where the catering company standard is to procure halal meat/poultry for standard meals too.
The KSML is a more unique meal than the MSML on most of those airlines having both meal types.
On some airlines, the special meal orders are great if wanting to be amongst the first served the meal in the cabin. The downside is then you may be waiting to get your tray picked up longer than average after finishing the meal.
