Carry on luggage with food.

[medhead]

McCain's Lasagna again?

(I understand now. )

Actually, in the drron school. Frozen left overs from home. Cheaper than pub grub every night. Better than 2 minute noodles. My hotel lets me use the kitchen at night.

Sadly the SYD drinks nights don't seem to happen. Or I don't pay enough attention.

If you crush the chip packets down you might be able to fit more in your hand luggage, but you might have a problem with the weight as removing the air from inside the packet will make them heavier.

Not sure if serious? Removing air from the packet will make it lighter.

I was wondering how long it would be before someone thought of that.

FWIW, the packet would also become denser - although the contents would in all likelihood no longer be able to be described as "chips".

Should not be a problem taking food in your carry on luggage. I have been doing it for over 4 years now and have not had any issues although most times I check the bag in as I am flying Qantas with a healthy luggage allowance.

The only time I had an issue was through Brisbane security where I had some cooked chicken in the bag. Security asked if it was raw chicken and I said no. I did not think it was an issue with raw meat anyway.

surely it would be easier to buy those at a supermarket rather than carry them (they can get heavy!)

Not always easier to buy at supermarket. Need to first find the supermarket and then the time to go and shop. If I go away for the weekend I usually take some food with me and do not eat out.

Removing the air from the packet would make no difference to the weight. I cannot believe some people cannot grasp simple physics. But to help them, the process is thus:

1.- You start with a packet that consists of three components - the bag, the chips, and the contained air. Each of these three components has mass and thus ¨weight¨.
2.- When you expel the air by squeezing it you vertically separate these three masses, with the air pushed upwards above the bag and chips. It is a natural instinct to do it this way (vertically) as you dont want to spill chips.
3.- The air expelled from the chip bag is heavier than the surrounding air (as it is laden with the scent of salt & vinegar, or other such) so it immediately settles back on top of the chip bag.
4.- So now you still have the same three components (masses), but now they are arranged in a different order. So the combination must weigh the same.
5.- The only way to achieve the goal of a lighter packet is to PLACE THE BAG ON ITS SIDE before expelling the air.

I would suggest to the OP that he merely heat the sealed packets of chips, as they will then actually rise like hot air balloons, and actually COUNTERACT the weight of the baked beans. Heating the baked bean cans would be beneficial also. It will cause the metal tins to expand, thus reducing their density, making them lighter too. The hotter the better - go for it!

It started as a promising physics lesson but finished so poorly. Reducing density by increasing the volume will not reduce the mass of material.

medhead, it was just a silly post.

But for the record, on a serious physics note, heating a can of baked beans does in fact make it lighter.

It certainly does not change the mass, but it does change the volume. The key here is that I used the word ¨lighter¨, which is a concept related to¨weight¨. If you place a helium-filled balloon on a scale it would not weigh anything, despite it having mass. A crude description of ¨weight¨ is ¨mass x gravity¨. This definition is only true in a vacuum. If an object is immersed in something with mass (such as a liquid or a gas), then it´s density (mass/volume ratio) defines it´s bouyancy which will alter the measurable weight.

Airlines measure the weight of carryons, not the mass. But it is the inertia of that mass that the aircraft engines have to overcome to accelerate along the runway and up to the point of cruising speed. At that point the inertia of that mass no longer poses a strain. To maintain height the fight is against ¨weight¨ now, in the sense that it is the effect of gravity on the mass that needs to be counteracted. And if the can of baked beans in your carryon is hot, it has a slightly greater volume, which means there is a tiny bit less air being carried within the aircraft, so it is in fact lighter. But obviously the difference is just a poofteenth, so heating your hand luggage will not remove the need for fuel surcharges.

Where has the OP gone?

Where has the OP gone?

He is waiting for another free computer to become available at the library. I truly admire the dedication of some to frugality.

 

[johnny_the_knife]

I do it all the time. Fruit, veg and unpackaged nuts are a problem travelling into many Australian states, but the things I carry, which usually include mostly health food type bars have never been a problem.

Personally, I'd be cryovacing both the chips and beans. This way it would fit in your bag better and the size reduction could allow you to take a few more days worth.

Grab one of those vacuum seal bags for any leftovers you want to take home, housekeeping should let you use their vacuum without any issues.

Bit of a timely reminder of advice late this afternoon in my office. coughroach! If you're taking food, make sure that you have plenty of sealed containers or bags, to help hide food smells that can attract vermin.

Now, which Hospital is it you work in again?

 

[medhead]

I know nothing!

On domestic flights ,are you allowed to take alcohol with you on carry on luggage? eg a cask of wine?

 

[medhead]

Same answer applies - as long as it fits within your carry on allowance, weight and size, yes.

 

[harvyk]

Yes, no problems at all (provided departing from domestic terminal), I've frequently taking bottles of booze on dom flights...

 

[Alanslegal]

What kind of carry on are you bringing? I hope its big enough for the cask of wine, packets of chips, mueslie bars and Shapes biscuits

Another thing, watch those weights even more carefully. A case of wine is likely to do in virtually half your entire carry on limit in one go. With a few cans of food, and a few other items you'll easily go through your 10kg. Don't forget that your carry on bag will have some degree of weight to it as well.

Remember that JQ are a LCC, and if they feel there is some money to be made from you, you can be assured they will enforce those carry on limits very carefully. You have a maximum combined weight of 10kg for all your carry on baggage, if they decide to enforce it and your over, and haven't pre-purchased the check luggage option, your up for some serious costs which will make buying stuff in Syd seem very cheap.

Again I'll suggest that you may want to simply purchase food items when you arrive in Syd, the exception is if you know you won't be able to find the food and drink items easily (but from the sound of it, your getting all standard commercial prepackaged food, available anywhere in AU), or if you don't think you'll have time to do so the day you arrive (in that case I'd only take a days worth, and buy the rest there)
