Most of our members carry their personal equipment and snack foods in their checked and carry-on luggage on their international flight.
In Britain, Europe, Australia, and other parts of the world, your baggage allowance may be as low as: 23 kilos/50 pounds of checked baggage, plus a small carry-on bag of 15 kilos/33 pounds (don't show the counter staff this much carry-on luggage upon check-in), for a total of 40 kilos/88 pounds. First ring your airline and request their "sport baggage allowance". Many airlines allow it, and often provide this for golfers, bicyclists, surfers and skiers. Quite often they extend it to climbers. Some of our members have had good luck bringing a ski bag and filling it with climbing equipment. WARNING: They might not give the same allowance on the inbound portion. Be sure to check this and request it if not given, or you could incur high baggage charges when coming home. The documentation of this allowance may take the form of a letter from the baggage officer at the airlines, or the allowance may be printed on the ticket itself (the best form of documentation by far).
If you are unable to attain a sport baggage allowance, obviously, those members coming from these countries will either be faced with wearing their climbing boots, helmet, duvet-clothing, etcetera onto the plane (this is normal procedure for many Australian, British, and European team-members), or paying excess baggage charges, or purchasing/hiring a portion of their equipment or daily snacks in Kathmandu, which is now becoming more and more of a viable option. If you chose to pay the airline's excess baggage charges, you might be faced with $20 per kilogram/2.2 pounds, of excess. Be sure to make full telephone and email inquiries before checking your bags at the airport.
Those members flying from North America are currently allowed 2 checked bags weighing 50 pounds/23 kilos each, plus one small carry-on weighing 30 pounds/13 kilos, for a total allowance of 130 pounds, or 60 kilograms. Baggage allowances change frequently. Before departure, you must ring your airline to verify the exact amount.
In North America it may be possible to pay an additional $120 per extra 70 pound/32 kilo bag, up to a total of ten or so extra bags, on flights bound for Nepal or China, but not for flights returning from there. However, be sure to ask about such "extra-bags" policies carefully before booking, and be sure to check with ALL of the airlines on your itinerary, as some of these airlines may try to "double-charge" you.
