If you fly regularly, you know the annoyance of having to check bags, especially if you have to pay extra for them.

Even worse is getting to your destination, tired and jet lagged, and realizing your luggage didn’t make it to the baggage claim. The carry-on bag helps you avoid these frustrations, but it can also be frustrating to try and fit everything you’ll need on your trip.

What flight attendants and frequent fliers have known for years is that with the right bag and some smart packing techniques, you can cruise through security, onto the plane and out of the airport with ease.

First, get a good carry-on bag.

It’s called a 22″ spinner carry-on bag. It’s the bag you see speedily rolling behind many pilots and flight attendants as they make their way to their next gate. Look for a sturdy, well-designed but lightweight bag with roomy pockets and a wide wheelbase. Spinner carry-ons get their name because of their four wheels. Bags with four wheels are easier to move around than those with just two. Airlines require carry-on bags that are small enough to fit under the seat or in the overhead compartment. Maximum size limits are typically 22″ long x 14″ wide x 9″ tall and 40 pounds. That’s why the 22″ spinner is a popular carry-on size. Most airlines allow you to carry on one small bag plus one personal item, including a laptop, purse or briefcase as long as it doesn’t exceed 36″ total and fits under the seat in front of you.

Understand what you can pack.

While you’re allowed to carry liquids, gels, and aerosols in your carry-on bag, there are restrictions you must be aware of before you pack. According to the Transportation Security Administration (TSA) website, all liquids, gels, and aerosols must be in 3.4 ounce (100ml) or smaller containers. Larger containers that are half-full or rolled up are not allowed. All liquids, gels, and aerosols must be placed in a single, quart-size, zip-top, clear plastic bag. Gallon size bags or bags that are not zip-top such as fold-over sandwich bags are not allowed. For more details about what you can carry on an airplane, visit TSA.gov/311.

Utilize all the space.

The key to maximizing space in a 22″ spinner carry-on is to roll your clothes into “tubes” instead of folding and stacking them like in a store. Rolling saves space and also helps prevent wrinkles. It’s also easier to select what you want to wear from your bag without unpacking the whole thing. Roll several items together to prevent more wrinkles. Don’t pack them in the carry-on bag as soon as you roll them. Once all the clothes are rolled, stand the carry-on up and pack heavier things such as shoes and books first at the wheel-end of the case so they don’t move around and crush the other items. One flight attendant claims she can pack clothes for 10 days by rolling instead of folding them. Another advocates the use of vacuum space saver bags.

Wear your nice, and harder to pack clothes and shoes on the plane. They won’t wrinkle or take up space in your carry-on. Even if you’re able to pack everything you want in the bag, keep in mind the typical 40-pound weight limit.
