International flight? Make sure you web-check in beforehand.

Do you have check in luggage? If you do, please be there latest by 10am. The queue to drop your luggage can be really long and slow. If I were you, I would be there by 9.30am.

If you do not have check in luggage, then you can be there around 10.30am, if 11am you will most likely have to be running already. Give yourself some time to walk to the gate and pass all the custom checks.

Why don't you check it in and label it fragile? Pay extra if needed to.

Either pack your own or buy the smaller containers of your toiletries from pharmacies.

It's not that difficult to pack your own. Just use any containers that are below 100ml and you are good. Toothbrush just bring any. Toothpaste buy a small tube.

It just means you're gonna burn the money you paid for the flight ticket.

I think it is borderline. You might wanna read thru the other backpack thread. I remember others saying preferably below 40L for handcarry.

Show your boarding pass and passport. Then you'll be given the gate number to go to.

Yes, but why would you need to bring those?

Meaning you have a check in luggage, you need to check in your luggage.
But you have already web check in (check in few days-weeks before your flight) and received a softcopy boarding pass which you print out using your own printer.

Yes, you need to go to the counter, usually it'll state BAG DROP COUNTER. And show them your boarding pass and passport.
They will tag your luggage, check it in and give you the gate number and any updates on your flight.

1. Yes. If no mention of maximum pieces then yes.

2. Unless it states 23kg per piece (which usually to America it's like that). Otherwise it's maximum 23kg, and 2 pieces only.

Yes. Unless it states maximum 23kg PER PIECE.

Just buy there. Usually Airbnb and service apartment will provide dish washer soap. You'll need to go to the supermarket to buy your raw food anyways.

Oil most places won't provide but we usually just get butter. Can use for bread spreads as well.

None that I know of.

Powerbank also none that I know of. Some airport states below 20k capicity each but didn't say limit to how many pieces.

I've brought around 3 phones, 1 tablet, 2 powerbanks and 1 laptop with me before.

Can. No problem as long as it's not Liquid, Aerosol or Gel.

No such thing. As long as not LAG, you can bring it on board. Of course you don't munch right in their faces when they are serving food. Some times they will politely tell you that outside food is not allowed. But you generally can snack on your own food at any other times.

I always bring snacks with me on board my flights.

Go to Thai Odessy and have a massage. 4 hours not much time.

It's not about which airlines, it's the airport. Some times they choose people to weight, sometimes they don't. Depends on your luck.

No such thing. It's 7kg max per bag per person. Not 7kg x 5 in a family. Usually they will weight your hand carry luggage only (cabin luggage) and not your handbag/backpack. But sometimes they might. My brother got charge for excess weight due to his heavy laptop when flying on Jetstar from Cairns to Auckland. Laptop weight is counted too.

Just passport.

You won't have any problems as long as your ETA is valid.

When you go thru immigration, prepare your return Melbourne-KL flight itinerary or booking confirmation. You won't have any issues like that. As long as you have a return flight ticket out of the country, you are good.

Best you ask the airport lounge when you are there.

Yes can. No issues bringing it on board.
Only issue is where you are arriving, whether you can bring it into the country you are arriving at or not.

You can print out the e-copy. What airline are you flying with?
Go to KLIA, check for your airline number on the board, see which counter you have to go to. Check in at that counter. You will get the boarding pass when you check in.

Is this your first time flying?

For the baggage policy, you can check on their website. Pretty sure they have the policy stated somewhere on the website. Most airlines are quite standard - 1 personal item and 1 hand carry luggage within a weight limit. The check in baggage should be 2 pieces if you're flying to the states.

You'll go to the check in counter, check your luggage in, get your boarding pass and inform the airline staffs if you have any other needs/requirement.
You should also double confirm your transit ticket and connecting flight. Make sure your check in luggage will be checked directly to your international destination, Chicago I assume. If in doubt, just ask the airline staff at the counter. Sometimes they give you the connecting flight boarding ticket, sometimes they give you a transit ticket. Sometimes you can use back the same boarding ticket. Go early to check in so you won't be late for your flight in the event there's any issue. 3-4 hours before flight.

You shouldn't have any problem. So far traveling in and out of Malaysia with all my personal belongings also no issue.

I assume you are flying with JAL since you will be transiting at Narita.

When you check in your flight in KLIA, you will be checking in all the way to US. I'm not sure about the domestic transfer in Texas but I'm pretty sure you will not need to check out and check in again at Japan. You are most likely required to disembark the plane and head to the next boarding gate. You definitely have to go thru immigration at your first point of entry in the US.

If you have any more doubts, you can clarify it with the airline staff when you check in at the counter.

Please use existing thread.

There is no issues on bringing 20,000mah powerbank. Just make sure you DO NOT check it in.

If you're on transit, you'll have to leave the plane with all your belongings. Follow the Transit signs in the airport, ask if you do not know. Most likely go thru security check again. Do not need to go thru immigration.

Check which gate you have to go to for departure to London. Go to that gate and wait for boarding.
