Luggage allowance summary

Generic planner only · always confirm with your airline

Choose units, enter how many people are on the booking, your per-person checked and cabin allowance, and the total weight you expect to check and carry on. The calculator compares your total to the group allowance and flags whether you look within limits or potentially overweight.

Assumptions: You know your airline’s allowance per traveler in either lb or kg. The calculator only compares weight. It does not handle piece-based rules, oversize items, or special sports equipment. All travelers on the booking are assumed to have the same allowance. Results are approximate and for planning only; airlines can still charge fees based on their detailed rules on the day.

Luggage allowance calculator — FAQs

Does this calculator guarantee I won’t pay baggage fees?

No. This tool is a rough planner only. It helps you see if your estimated baggage weight is under a simple per-person allowance, but airlines can still charge fees based on their own rules, scales, and piece limits. Always double-check your specific ticket and airline policy.

Why does the page load in pounds (lb)?

Many airlines and travelers use pounds for baggage limits, so the calculator loads with lb by default. If you prefer metric, switch to kilograms (kg) in the units dropdown and the labels and default hints will adjust.

How do I handle piece-based rules, like "2 x 23 kg"?

This calculator keeps things simple by working with a total weight per traveler. If your allowance is 2 x 23 kg, you can treat that as 46 kg per person. Just be aware that your airline might still enforce per-bag limits even if your total weight is fine.

Should I include personal items and small bags?

If your airline weighs carry-ons and personal items together, it’s safer to include them in your cabin total. If they clearly say a laptop bag or small purse is free and not weighed, you can ignore those for this rough calculation.

How to use this luggage allowance calculator

This luggage allowance calculator is designed for quick pre-trip checks: you know your airline’s baggage limits, you have a rough idea of what your bags weigh, and you want to see if your group looks safely under or uncomfortably close to the allowance. No airline lookups, no accounts — just a simple weight comparison.

1. Start with travelers and units

First, choose how many travelers are on the booking. Then pick your preferred units. The page loads in pounds (lb) by default since many airlines publish limits in lb, but you can switch to kilograms (kg) if that’s easier for you.

2. Enter your per-person allowance

Take your ticket or airline policy and enter the checked baggage allowance per traveler and the cabin or carry-on allowance per traveler. If your airline uses piece-based rules (for example, 1 x 23 kg checked), convert that to a single total per traveler before you type it in.

3. Estimate what you plan to bring

Next, add the total checked weight and total cabin weight for everyone on the booking. A luggage scale is handy here, but even ballpark numbers are useful when you’re deciding whether to move items between bags or pre-buy extra allowance online.

4. Read the result and tweak your plan

Hit Check luggage and the result hero tells you whether you appear to be within your group allowance or overweight, and by roughly how much. Beneath that, you’ll see your total allowance and planned weight broken down, plus an average per traveler so you can see who might be carrying more than their share.

Use the Copy summary button to paste a short text summary into your packing checklist or share it with friends and family. When in doubt — especially if you’re close to the limit — it’s still worth weighing each bag individually and checking your airline’s exact wording on checked, cabin, personal, and oversized items.

How the luggage allowance math works

The calculator only works with simple totals. Let N be the number of travelers, A_checked the checked allowance per traveler, and A_cabin the cabin allowance per traveler, all in the same unit (lb or kg).

Total group allowance is:

Group allowance = N × (A_checked + A_cabin)

Let W_checked be your planned total checked weight and W_cabin your planned total cabin weight. Total planned luggage is:

Planned weight = W_checked + W_cabin

The planner then computes the difference:

Margin = Group allowance − Planned weight

If the margin is positive, you’re roughly within your allowance by that many lb or kg. If it’s negative, you’re approximately that much overweight. A simple per-person average is also shown by dividing both the allowance and planned weight by N.

This doesn’t cover every nuance of airline rules, but it gives you a quick signal if you’re cutting it close and might want to redistribute items, drop a bag, or pre-book extra luggage before you get to the airport.
