Airline Luggage Allowances: Size Limits, Weight & Fees

Last Updated: July 7, 2026

If you’ve flown recently, you’ve probably noticed how complicated baggage fees have become. Not only are the rules complex, but the fees seem to be constantly increasing.

Ever since airlines began unbundling their fees, baggage rates have been on the rise. Henry Harteveldt, President of Atmosphere Research Group said in an interview with CNN,

Airlines are raising bag fees in part because of higher labor costs, and in part because they want to - and they can. Passengers don’t like paying to check bags, but they generally don’t change airlines over the price of the associated fee.

Maybe not, but if you know the baggage allowance rules and how they can vary among airlines and routes, you’ll be more prepared to minimise the amount you end up paying. Here, we're going to give you an overview of what to expect, so you can keep your baggage fees at a minimum the next time you fly.

The Basics of Airline Baggage Policies

Whether you’re flying with a full service or a low cost airline, your luggage will have to meet certain size and weight requirements. Plus, according to which airline you fly with, you might have to pay fees for carry-on bags as well as checked luggage. But depending on your route and cabin class, you might not have to pay anything.

Baggage Fees

How and when you choose your baggage options also makes a difference in how much you’ll have to pay. Baggage fees for low-cost airlines tend to be lower the earlier you choose and pay for your luggage allowance while legacy carriers fees are based more on whether you pay for checked bags online or at the airport.

Luggage Allowances

A luggage allowance refers to what you are permitted to bring with you, either in the cabin or in the aircraft hold.

Just like baggage fees, allowances vary significantly between low-cost and full-service airlines. In most cases, passengers are allowed to bring at least one small personal item, such as a handbag or purse. Whether you can also bring a larger carry-on bag, and at no extra cost, depends on the airline and the fare type.

With low-cost airlines, carry-on bags are often not included in the base fare. Size limits also tend to be more restrictive, meaning anything larger than a small personal item usually comes with an added fee.
Legacy airlines, on the other hand, generally include one free carry-on bag in the ticket price, although this can be limited or removed in the lowest economy fare classes.

Checked baggage allowances introduce even more variation. Weight limits, size restrictions, and fees can differ widely by airline and fare type, which we will break down in more detail later.

Baggage Fees and Allowances Compared

In all regions, airlines can set their own rules for baggage allowance and fees, and passengers can see big differences between full and low cost airlines.

Comparing Low Cost and Full Service Airlines

As mentioned, once baggage fees are added, passengers can end up paying just as much for a low-cost airline ticket as they would for a full-service fare. Low-cost carriers often charge higher overall fees for checked baggage and, in many cases, also apply charges for carry-on bags.

To illustrate this, we looked at a selection of UK and EU airlines and compared the baggage fees and allowances for a standard economy ticket to see how they stack up.

Airline	Carry-on Baggage	Checked Baggage
British Airways	Included free in economy fare: 1 carry-on (56x45x25cm) + 1 personal item (40x30x15cm)	1 checked bag included free with economy fare Max dimensions up to 90 x 75 x 43cm (35 x 30 x 17in) Weight up to 23kg (51lb) per bag

Additional Baggage Options

Baggage allowance doesn’t end with suitcases and carry-on bags. Most airlines have special fees, rules, and requirements for a wide range of other items you might want or need to travel with including:

Extra baggage
Overweight or oversized bags
Sports equipment like bikes, ski equipment, etc
Car seats and other kid-centric items
Pets

Passengers travelling with children or babies, medical equipment, mobility devices, or any other special item will have to dig even deeper into airline policies to prepare and comply with the rules.

Bottom Line
