can't say for sure. depends on your luck. I have seen some airlines strictly enforcing one hand carry luggage only while I have got away with one backpack and one shoulder carry. I think the trick is to make them appear light. Anyway, for you convenience and others, try not to have too many hand carry. I cannot stand those people that carry "big packet small packet" when they could have check them in. Because of the need to bring out laptop during security scanning. I have now proceed to check-in my laptop as well. Just bubble-wrap them and put them into the carry case. Then put the case between the clothes in your luggage.
By right laptop bag and camera bag can bring on board and it is not counted as one of the hand carry luggage.
When I came back from oversea after outstation for a year, i managed to carry
60kg without excess luggage fee.
1x
27.8kg suit case checked-in (limit was 25kg, purposely pack the suitcase in such a way to make it slightly less than 28kg)
3 sets of big kites checked-in (the poles are over 1.5m, too long to stuff inside suitcase)
hand carry close to 30kg onboard:
2x laptop bags (i had 2 laptops -
easily 5-6kg including the bag)
1x lowepro mini-trekker with tripod strap on it (easily
10kg for the camera bag alone - 1D body + 3 L lenses + 2 primes + 1 flash)
1 x sling bag (another
10 kg)
I also wear all my heavy winter clothing and strap 1 jacket around my waist.
U can imagine i was walking with 2 laptop bags on shoulder, 1 sling bag behind me and 1 camera bag on my back and pulling a 30kg suitcase...sweating with all the thick winter clothes on my body :bsmilie:
