oneworld member Malaysia Airlines had posted a notice that they weren’t going to accept checked bags on European flights due to unusual headwinds.
It’s hard to imagine taking a European flight with only carry ons, let alone with an economy allowance of ~ 15 pounds. And it’s unclear what it means for checked baggage to “only arrive later” (perhaps in a few days when the headwinds die down?).
The temporary change, though, is also related to how Malaysia Airlines is responding to the 2014 shooting down of one of their jets.
