Flying from Dublin to Wellington at the end of this year. We arrive in Melbourne with EK and change to QF to Wellington. Will we be able to check bags the whole way through from Dublin?
I'm assuming the answer is yes but just wanting to check.

And then less likely, later in the trip we fly Melbourne to KL on EK and then on to Langkawi with MH. This is a seperate ticket. Any chance we can check bags through here?
We have a 6 hour layover in case we have to claim bags and re check them.

Final question: do you get amenity kits in First on all flights or just night flights?

Thanks for any info
