I can get all my kit into a 80l bag (weighed in at 20kg) and a 45l petzl transporter. No idea of the weight of the transporter but probably about 12kg. Transporter had all my textiles. Only caving kit in the hand luggage lithium batteries. I have also do Eva 4 day trip to France, with all my cave kit in hand luggage. The French were not impressed when we flew back as all the metal work was covered in mud.
I also suspect that what ever you use for a cooker you will need to buy the fuel in the country as not sure you can fly with it.
