You are permitted to bring a backpack in addition to your carry-on baggage provided that the backpack does not count as a personal item and that it satisfies the size and weight requirements for carry-on luggage.
Most airlines allow passengers to bring on both a carry-on and a personal item like a backpack, laptop bag, purse, briefcase, shopping bag, etc. The general rule of thumb is that your personal item is smaller in dimension than your carry-on bag and it can fit underneath the seat in front of you.
In most cases, backpacks are considered personal items as long as they fit under the seat in front of you. For example, if you use a backpack as a personal item and put it under the seat in front of you, you can then use a duffel as a carry-on bag as long as it's under the airline's size requirements.
A: It depends on the airline you are flying with. Most airlines allow passengers to bring one personal item and one carry-on bag. However, some airlines, such as Southwest and Delta, permit passengers to bring a second carry-on bag that is smaller in size and can be stored in the overhead bin.
Some airlines allow several personal items, while others allow one and a carry-on bag. If an airline permits two personal items instead of a carry-on, the second item must be small enough to fit beneath the seat in front of you.
You are allowed to bring onboard two (2) pieces of bag as part of your cabin baggage allowance with the total weight of both items not exceeding 7kg.
If the backpack is bigger than 22″ x 14″ x 9″, then no. If it is exactly that size, and you also have a second bag that big, then no; you are allowed to bring only one bag and one personal item onto the plane, and that backpack would be too large to be considered a personal item (those max out at 17″ x 10″ x 9″).
The 40L will max out carry on dimensions on most airlines so you never have to check a bag. For stricter airlines, like RyanAir, 30L will be a better choice.
30L or 40L backpacks are great options for primary carry ons but are usually too big to be considered personal item that need to be small enough to slide easily under the seat in front of you.
In addition to your carry-on baggage allowance, you may also carry onboard one small personal item such as a handbag, laptop computer*, overcoat, small camera, a reasonable amount of reading material or a small amount of duty free goods (where permitted).
How Strict are Airlines About Personal Items? As long as your bag fits under the seat in front of you, you can probably get away with a bag that's slightly over your airline's size guidelines. However, just as the size restrictions vary by airline, so does their enforcement of those restrictions.
If your instrument is too large to fit in the cabin, you can also purchase a seat for it. Just make sure that it meets the airline's size and weight requirements before you board. Finally, you can also bring military bags and sports equipment as carry-on item.
Including wheels and handles, measurements may not exceed 22 inches long, 14 inches width and 9 inches high. The total length plus width plus height of baggage must not exceed 45 linear inches. For personal items, Delta says size examples are purses, small backpacks and laptops.
Your backpack will generally be allowed as a carry-on if it's under 50 liters, or about 22 x 14 x 9 inches. Get a 45-liter backpack if you want to carry as much stuff as possible on the plane with you. All Knack Packs are carry-on friendly (under 50 liters).
Personal Item Size Limits
American Airlines advises customers to travel with personal items that are no larger than 18 inches x 14 inches x 8 inches. If you are flying on Delta, be sure your personal item is 17 inches x 13 inches x 9 inches or smaller.
Most airlines allow carry-on luggage that measures up to a maximum of 22 x 14 x 9 inches. In terms of volume, backpacks that are 40-45 liters are good as a carry-on. Anything bigger than that might require you to have it checked in instead.
21–35 liters: This is the sweet spot for most hiking and travel daypacks. There's enough capacity to hold food, clothing and some extras, like a camera and a book. 36–50 liters: These larger packs are ideal for trips that require additional clothing and gear, such as climbing, mountaineering or non-summer hiking.
The 45L Travel Backpack is fully carry-on size compliant, though this does come with an asterisk. By default it has a capacity of 35 liters, putting it well within any airline carry-on size limits.
A weekend backpack like a standard 40L backpack is big enough to carry a backpacking sleeping bag, small tent, and pad, as well as extra clothing and layers. Other things you'll need to carry include a small stove, food and basic cookware, plus a water filter/purifier, first aid kit, and navigation tools.
Bags larger than 45L cannot be carried on. If you see a 50L backpack marketed as a carry on , double-check the dimensions. It's probably too big to technically qualify as a carry on .
The short answer: Yes, a backpack is generally considered a personal item if it fits under the seat in front of you. Most airlines offer a few examples of things that fit into the “personal item” category, such as a purse, laptop bag, or a briefcase, but they don't usually include “backpack” on those lists.
Carry-on baggage. Each passenger is allowed one piece of carry-on baggage with a maximum total dimension of 56cm x 36cm x 23cm (22in x 14in x 9in) and maximum weight of 7 kgs. (15 lbs).
For an additional fee, you can carry excess baggage heavier or larger than what is allowed on both our international and domestic sectors. The permissible weight of check-in baggage is 23 kg/50 lb. Overweight charges will apply for any baggage weighing between 23 kg/50 lb and 32 kg/70 lb.
contents must fit comfortably inside the bag so it can be sealed. the bag must not be knotted or tied at the top. you're limited to one plastic bag per person. you must show the bag at the airport security point.
Most Airlines Don't Care if Your Carry-On Is 1 Inch Too Big. Carry-ons are measured at the airport before boarding the plane. It's done with metal measuring boxes just in the right size for the allowed carry-on dimensions. If your bag is too large and it isn't flexible, you won't be able to fit it inside.
