Sterilization is done by a combination of temperature and time. You don’t achieve good sterilization by raising the temperature to 100 degrees Celsius for a moment and then letting it cool down. These high temperatures must be maintained for at least 60 seconds. The powerful microwaves boil the water faster and superheat the steam, and so require less time, whereas the less powerful microwaves take more time to bring the water in the bag to boiling point and do not superheat the steam significantly.

One of the easiest costs to eliminate is the previously mentioned checked bag fee. In case you haven’t noticed, or don’t travel much, the airlines will let you get on an airplane with just about any size luggage as carry-on. Of course they have their carry-on size requirement guides at the airport, but you’ll almost never hear any of the airline personnel reference these guidelines anymore. Now don’t take this to mean that you can come walking up to the aircraft with a steamer trunk as carry-on, cause that won’t fly (bad pun, sorry). You still have to get your suitcase through the baggage-screening machine at the security checkpoint, so you have to be somewhat reasonable. But I have seen some pretty monstrous backpacks and overnight bags that easily fit through the x-ray machines.

So here’s what you do. Go to Google, Amazon.com or whatever your favorite online store is for bags. Do a search for “overnight bags”. From here you’ll have a huge selection of bags that you can use when you travel. Because they are in the overnight bag category, most of these bags will be sized just right for you to carry them on a plane with you.
These bags have lots of great features. For one they are extremely easy to pack and unpack. Many of them have lots of pockets on the inside and the outside of the bag. This makes organizing your stuff a breeze. They also typically come with handles and a detachable shoulder strap. Handles are perfect for most situations. But the strap comes in really handy when you’ve loaded your bag with stuff and need to huff it through the airport to catch a connecting flight. Some of the bags even come with a stow-away handle and wheels for rolling the bag.

Because of their size and construction, these bags have many advantages over roll-aboard suitcases. For one they are extremely easy to get through security. Unlike a rigid suitcase, overnight bags are typically made from more flexible materials. So even if you’ve stuffed it to capacity, you can still get it through the scanning machines at security. This also helps when you’re trying to squeeze your bag into an overhead compartment. If you travel a good bit, you’ve heard the term handles or wheels out. Essentially the airlines are trying to accommodate as many bags as possible in the overhead compartments. For this reason, they want the bags placed in with the handles or wheels facing the isle of the plane. Some roll-aboard bags just won’t fit this way because of their rigid construction. But this won’t be a problem with your flexible bag.
