GVA-HKG: 2 segments connecting -

LH 2387 GVA-MUC Business Class;
LH 730 MUC-HKG First Class

May I ask what your experience has been on those flights please?

The class I'll be flying and equipment for those segments are:

GVA-MUC Canadair Regional Jet 900 Business Class

MUC-HKG Airbus A340-600 First Class


I'm wondering how the carry on limits may differ between my initial flight when I board at GVA on the short flight to MUC as it is a smaller Canadair 900 plane, and I'll be flying Business Class, not First Class, versus the MUC-HKG on the A340-600 when I'll be flying First Class.

Thank you.
