Pardon me for flooding this a bit
Looks like at least two Thai flights - to Stockholm and Moscow - took the L888 route today. As well as Azur Air on B763ER Krabi-Moscow ZF7734/KTK7734 is aiming to the same route as well.
If you're keen to know more about the establishment of L888, escape routes etc., google for "L888 flight route", images - there's a presentation from Qantas on a blue backgound covering the creation and early days of L888.
