Checked Bag Fees and Weight Limits
The checked luggage weight limit is a common source of unexpected airport charges, yet most advice about checked bag fees focuses on paying them rather than avoiding them. This guide explains the common weight limit for checked bags, how overweight fees work, three easy ways to weigh your suitcase at home, and the detail most people miss: how much of your weight limit the empty suitcase uses up before you pack anything.
Key Takeaways
- The most common checked luggage weight limit is 23 kg (50 lb) per bag in economy.
- Overweight fees are often higher than the cost of checking the bag itself.
- You can weigh a bag at home with a luggage scale or a bathroom scale.
- An empty large suitcase can use 4 to 6.5 kg of your allowance.
- Aim to stay about 1 kg under the weight limit to allow for scale differences.
Common Checked Luggage Weight Limits
Limits vary by airline, route and fare, so always check your ticket. These are the typical rules, checked in September 2026.
| Fare or rule | Typical limit | Notes |
|---|---|---|
| Economy, most airlines | 23 kg (50 lb) per bag | The most common checked luggage weight limit |
| Premium economy and business | Often 32 kg (70 lb) per bag | Varies by airline and route |
| Weight-based allowances | A total, such as 20 to 30 kg across all bags | Common on some international routes |
| Maximum single bag | Often about 32 kg (70 lb) | Heavier bags may need to be shipped as cargo |
| Size | Often 158 cm (62 in) total length, width and height | Oversize fees can apply on top of weight fees |
Piece allowances vs weight allowances
Many airlines use a piece allowance: a set number of bags, each with its own weight limit. Others, on some international routes, use a total weight allowance shared across all your bags. With a total allowance, one heavy bag and one light bag is fine, as long as the total stays under the limit.
How Checked Bag Fees Work
Checked bag fees fall into three groups:
- Standard bag fees: many fares, especially basic economy, charge for the first checked bag; others include one or two.
- Overweight fees: charged when a bag goes over the weight limit, often in steps, with higher fees for heavier bags.
- Oversize fees: charged when a bag exceeds the size limit, and can be added on top of overweight fees.
Fees change often and differ by airline and route, so check your airline's current fees before you fly. The key point: an overweight fee is frequently more than the cost of checking a second bag, so going over the weight limit is rarely the cheapest option.
Three Ways to Weigh Your Suitcase at Home
1. A luggage scale
The easiest and most accurate method. Hook the scale to the suitcase handle, lift until the bag hangs clear of the floor, hold it steady, and read the weight. Small digital luggage scales are light enough to pack for the return journey.
2. The bathroom-scale method
No luggage scale? Weigh yourself on a bathroom scale and note the number. Then pick up your suitcase and weigh yourself again while holding it. Subtract the first number from the second, and the difference is your bag's weight.
Example
If you weigh 70 kg alone and 91 kg holding your suitcase, the bag weighs 21 kg, safely under a 23 kg weight limit.
3. The bag on the scale
For smaller bags, stand the bag directly on the bathroom scale. If it hides the display, lay a flat board or tray across the scale first, weigh the board alone, and subtract it.
Allow a margin
Home scales and airport scales can differ slightly. Aim to stay about 1 kg under the checked luggage weight limit to be safe.
How Much Your Empty Suitcase Costs You
This is the point most people miss. Your suitcase's own weight counts against the weight limit before you pack a single item. Here's what a large, 28 inch suitcase typically leaves you under a 23 kg limit.
| Large suitcase type | Typical empty weight | Left for belongings |
|---|---|---|
| Softside | About 4 to 5 kg | About 18 to 19 kg |
| Polycarbonate hardside | About 4.5 to 5.5 kg | About 17.5 to 18.5 kg |
| Aluminium-frame hardside | About 5.5 to 6.5 kg | About 16.5 to 17.5 kg |
A kilogram or two of case weight can be the difference between an overweight fee and none. If you often fly on weight-limited fares, a lighter case pays for itself. Aluminium-frame cases offer strength and security, but they're among the heaviest, so they suit generous allowances better than tight ones.

How to Stay Under the Weight Limit
- Wear your heaviest items: boots, jackets and sweaters travel free on your body.
- Redistribute between bags: move heavy items to a lighter bag or your carry-on, within its own limits.
- Pack fewer shoes: they're among the heaviest things you pack.
- Decant toiletries: travel sizes weigh far less than full bottles.
- Choose a lighter suitcase: every kilogram saved is a kilogram you can pack.
- Weigh again before flying home: souvenirs push many bags over the weight limit on the return trip.

At the Airport: If You're Over
If your bag is over the checked luggage weight limit at check-in, you usually have a moment to fix it. Move heavy items into your carry-on, if it has room within its own limits, or wear them. A foldable spare bag lets you split the load into a second checked bag, which is often cheaper than an overweight fee.

Frequently Asked Questions
Is 50 lb the standard luggage limit?
For economy checked bags, 23 kg (50 lb) is the most common limit, though some airlines and fares differ. Premium cabins often allow 32 kg (70 lb), and some routes use a total weight allowance instead. Always check your ticket.
How much is an overweight baggage fee?
It depends on the airline, route and how far over you are, and fees change often. Overweight fees are frequently higher than the cost of checking a bag in the first place, so it's usually cheaper to move items to another bag.
How can I weigh luggage at home without a scale?
Use a bathroom scale: weigh yourself, then weigh yourself holding the bag, and subtract the first number from the second. It's accurate enough to tell whether you're close to the limit.
How much does a 28 inch suitcase weigh empty?
Usually about 4 to 6.5 kg, depending on construction. Softside cases are lightest, polycarbonate hardside is close behind, and aluminium-frame cases are heaviest. That empty weight counts against your allowance.
Is a luggage scale worth buying?
Yes, if you fly more than once or twice a year. A small hanging luggage scale costs less than a typical overweight fee, weighs little, and lets you check your bags before both the outward and return flights.
