You can place the liquid inside the checked luggages. I have done this.

ok, i guess it applies to both domestic and international flight right?

yup

Any tips on how to identify your luggages quickly at the carousel, apart from tying ribbon and pasting stickers?

1) Open eyes big big. Like this -> 
2) Be more kiasu than Singapore people. Stand at the front-most of the conveyor belt.
3) Get weird colour luggage bag like pink, orange, fluorescent green, bright yellow.

Haha yeah, i am always the kiasu one. always worry that if i dont get it pick up, someone will took it away.
Sad to say all my bags are in black color 

During summer, especially during major heat wave peak season, always have bottles of water ready in your bag wherever you go. And if you need to buy bottles of water, it's wiser to get it straight from the supermarket itself. I went backpacking in Europe and halfway through, a friend bought two large bottles of mineral water at a nearby kiosk in Amsterdam, it cost us 3 Euros each. Later when we went to the supermarket, we discovered that that same bottle is only 99 cents.

So yes, any food/beverages are best done in the supermarket to avoid scams.

Bring some sunblock lotion as well. The heat does damage your skin during this time of the season. Actually it's cheaper to purchase your things through credit card rather than cash when converted to local currency.

If you have allergies or for emergency purposes, bring necessary medications with you like vitamins (it is important to get as much vitamin c), aspirins etc. If you're going away for longer than 3 weeks or so, make time for check up a month before just to make sure that you're fit to travel.

If you want to redeem your tax, you can fill in the form at the airport, but make sure you're early to avoid being in a rush.

It won't be a problem to get anything liquid and keep it in your check in luggage. It's only a no-no when it comes to hand carry bags.

May i know the redeem tax is what???

Is GST/VAT . Go google for more info.

What it means is, when you (as a tourist in foreign land) purchase some things at certain shops (not all) which charge GST (inclusive), you have to pay for it.
However, since you are tourist, when you leave the country at the airport, you can claim back the GST paid. Sometimes these counters are after the immi & customs at departure hall.
Do note that most will have minimum sum purchase, as there is a small admin/processing fee to claim the GST.

Those liquid shold put in where? the big luagage or my backpack?
The weather.com shows feb 18 in korea will be hte ending of winter. So wht clothes is suitable in there n also the shoes?

Please advise  as i am really a NOOB~!

Handcarry luggage = the backpack or another smaller luggage you carry with you on board the plane and to put in the compartment above your seat when you are in the plane (No liquid above 100ml and sharp items)
Check-in luggage = the big luggage bag that you'll check in and never to be seen again until you arrive your destination

Liquid above 100ml are all to be packed into the check-in luggage. Also sharp items like knifes, nail clipper, scissors all go into check-in luggage.
Check with your airline the weight limit for check-in luggage and handcarry luggage. Also take note of what is not included in the hand carry luggage weight, usual stuff like laptop, camera, books can be excluded from your handcarry luggage weight.

For winter clothings and what to prepare, check the other thread dedicated to winter wear: http://forum.lowyat.net/topic/972657/

I get to know nothing should above 7kg. so the 7kg = handcarry+check-in luagage. The dslr can put in the handcarry n timbang together right?

No no, check-in luggage is usually 15kg-20kg. Handcarry and check-in luggage is two different thing.

Are you flying Airasia? If Airasia then check-in luggage will depend on how much baggage weight you bought.

Handcarry is fixed at 7kg for Airasia.

If 7kg for both definitely not enough.  Roller luggage bags are already 3-4 kg by its own.

DSLR can put into hand carry luggage, if your hand carry luggage is over 7kg with the DSLR, you can remove the DSLR and timbang again cause camera usually no count.

im flying with airasia D7. means if 1 ppl goin, i need to buy the 15kg for the luagage? if i got 2 luagage-check-in, then i need to pay 2x 15kg or 1 time, combine both?

any recomendation how much need to buy when i go, and back that time?

Since you first time travel, just to clarify further:

- 100ml bottles, which means you can't put >100ml liquid in it. You cannot argue you have a 500ml bottle with just 10% left (50ml).

- hand-carry is by hand you bring into plane, such as handbag, laptop computer, camera or any other valuables.
7kg for this. Limit is 1 backpack/slingbag + handbag.

- check-in is go into storage during the flight. You can't access it until you reach destination. This is depends how much you purchase.

- If 2 person, is up to you. You can buy 2x 15kg, or 2x 20kg, or 1x 30kg, etc. But BOTH must check-in together.

- For Korea during end-Winter, it is still cold for most M'sians. Therefore, you'll be bringing a lot of sweaters, jackets, cardigans, scarfs, why do they have so many different types ????, etc. which will take up space and weight. My suggestion is minimum 20kg each, with some allowance for souvenirs, etc.
You can either use 1x luggage or 2x or even 3x to check-in. It depends how many luggages you can lug around only.

boboi..thank you so much. Just to clarify, means that when i going to S.Korea, even i am going there with my friend, i can buy one pack of 15kg n the 15kg must be 1 luaggage or combination of both luagage also can?
