Checked luggage is now the standard on most North American based airlines. Checking luggage is becoming more common and can cost $25 or more per bag. But you can defy the system that up-charges. Eliminating the extra baggage will be unbelievably liberating too.

You can travel for short or long periods with only a carry-on luggage. No more worrying about lost luggage and waiting for hours at baggage carousels. You embrace the simplicity as a respite from consumerist habits. You are much more mobile when it comes to transportation. Having one manageable bag is easier to keep an eye on.

Here is how to travel with only a carry-on backpack:

1. Pack what you "know" is needed, rather than what you "might" need.

According to the Carryology HQ team in The Best Backpacks for One-Bag Travel, "The space in our pack is a precious commodity. It should be used efficiently and guarded from our own laziness of packing items 'just in case'."

For an unexpected cold spell, buy sweaters/fleeces at a thrift store instead.

2. Wear your heaviest clothes and trail shoes on the plane.

Don't underestimate the impact of this. 

3. Choose your liquids wisely.

If you're staying at a hotel, you likely toiletry essentials. See if you can get a mini version of shampoos and conditioners or invest in some of those handy travel containers. You can pack multiples if you need plenty.

4. Pack for a week.

Only pack enough clothes for a week if you're traveling for a year and then just do laundry. Laundry services are inexpensive in many parts of the world, or rent Airbnb apartments with washing machines.

Pare down to the essentials. Choose lightweight, quick-drying fabrics and make sure all your clothes can be worn together while still, you are prepared for every situation.

5. Choose a 40L backpack.

The less your carry-on weighs empty, the more the stuff packed inside can weigh.

6. Check your airline's luggage policy.

First, check the size and weight requirements of the airline you'll be flying. Check your bag's dimensions against budget carriers like Ryanair before purchasing. Ensure that it will be comfortable to lug around the airport. Some airlines charge a premium if you don't check the size and weight requirements and are busted at the gate. Some airlines only allow a person one bag, period.

7. The rolling method

Rolling or folding your clothing doesn't make any difference to its weight. However, rolling not only maximizes the space in your carry-on but it also helps keep wrinkles at bay. This helps if you want less ironing work and want to look more professional if going on a business trip or simply presentable.

8. Pack solid toiletries.

Choose solid toiletries whenever possible as you are restricted to bringing liquids in bottles of 100 ml (3.4 oz) or less. Lush shampoo bars are fantastic. A tiny bottle of shaving oil lasts nine months. A mooncup takes up less space than tampons.
