Depends how patient you are
Don't worry, they have a compressor. You can save the space in your luggage. Unless you're pump is made from solid metal, you won't save much weight though
Thanks for the answer.
I am flying from London with Egypt Air and I have been told that over sized luggage are charge by weight.
I am therefore planning to stip my board from everything, carry the "nacked" board of a simple bag and and put my 2 kites, harness, 2 bars, board equipement (handle, fin, foot strap) in my standard suitcase.
I tried, it fits with the pump put I am very close to the 20 Kg limit and a still to put a few clothes.
So getting rid of the pump will be good for the space and weight.
