What is the standard airline baggage allowance?

There is no single standard. In this tool's reference profiles, large US airlines use a 22 × 14 × 9 in carry-on and a 62-linear-inch, 50 lb checked bag, while many European airlines use 158 cm and 23 kg for checked bags. Whether any bag is included free depends on your fare, route and status.

What is the airline baggage weight limit?

For a checked economy bag, most airlines in this tool use 50 lb (23 kg); Frontier uses 40 lb, Ryanair sells a 20 kg bag and the Singapore Airlines profile allows 30 kg. Spirit raised its limit from 40 lb to 50 lb. Carry-on weight limits, where set, range from 7 kg (Emirates, Qantas, Singapore Airlines) to 23 kg (British Airways), and most US airlines in the list set none.

What size is a personal item on most airlines?

Published personal-item limits in this tool range from 40 × 20 × 25 cm (Ryanair's free small bag) to 45 × 36 × 20 cm (easyJet). US examples: American, Spirit and Frontier 18 × 14 × 8 in, United 17 × 10 × 9 in, JetBlue 17 × 13 × 8 in. Delta, Alaska, Emirates, Qantas and Singapore Airlines publish no fixed size; the item just has to fit under the seat in front of you. The only size that passes every published limit here is about 40 × 25 × 10 cm (15.7 × 9.8 × 3.9 in), because United allows just 10 in of width and Lufthansa 10 cm of depth.

Which airlines allow the biggest carry-on?

Among the 18 airlines here, the most generous are Southwest and Frontier (24 × 16 × 10 in), Spirit (22 × 18 × 10 in), British Airways (56 × 45 × 25 cm, up to 23 kg) and easyJet's paid large cabin bag (56 × 45 × 25 cm, 15 kg). A standard 22 × 14 × 9 in bag passes every US airline in the list but fails the 55 × 35 × 25 cm Air France–KLM, 55 × 38 × 20 cm Emirates and 55 × 40 × 23 cm Lufthansa and Air Canada limits. Enter your bag and leave the airline blank to see the full list.

Does a 66 cm suitcase fit checked baggage size limits?

Usually, but 66 cm is only the height. Checked limits are normally the sum of length, width and height: a 66 × 44 × 27 cm case totals 137 cm, under the common 158 cm (62 in) limit. Enter all three sides above to check a specific airline.

How accurate are the airline limits shown?

They are reference profiles, not a guarantee for a specific ticket. Airlines update policies and may vary allowances by fare, route, cabin, loyalty status and operating carrier. Use the official-policy link in the result and the allowance printed in your booking before travel.

Does the linear inches / total size matter?

Yes — many airlines specify a maximum linear size (length + width + height combined) in addition to individual dimension limits. This tool checks both per-dimension limits and the linear total where applicable.

What is the difference between a carry-on and a personal item?

A carry-on goes in the overhead bin. A personal item (purse, backpack, laptop bag) must fit under the seat in front of you. This tool focuses on carry-on and checked bag rules; personal item limits vary widely and are typically smaller than carry-on limits.

Why might my bag pass the size check but still get gate-checked?

Airlines reserve the right to gate-check bags when overhead bins are full, even if the bag meets size limits. Full flights and early boarding groups reduce this risk.

Are carry-on weight limits always enforced?

Enforcement varies by airline, airport, route and flight. A bag may be measured or weighed at check-in or at the gate, so use the operating carrier’s current policy instead of assuming a limit will not be checked.

Quick answer

Airline baggage allowance is the size and weight of bags your ticket lets you bring. A common reference is a 22 × 14 × 9 in (56 × 36 × 23 cm) carry-on and a checked bag up to 62 linear inches (158 cm) and 50 lb (23 kg), but limits vary by airline, fare and route.

Examples

Airline (reference)	Carry-on	Checked bag
American, Delta, United	22 × 14 × 9 in	62 in total, 50 lb
Frontier	24 × 16 × 10 in, 35 lb	62 in total, 40 lb
Ryanair	55 × 40 × 20 cm, 10 kg	119 × 119 × 81 cm, 20 kg
Lufthansa	55 × 40 × 23 cm, 8 kg	158 cm total, 23 kg

Summary

This tool compares bag length, width, height and weight with personal-item, carry-on and checked-bag reference profiles for 18 major airlines, and lists every airline the same bag passes or fails. It checks dimensions independently of whether a bag is included in a particular ticket. Fare family, route, cabin, loyalty status, codeshare operator and date can change the actual allowance or fee, so every result includes a link to the selected airline’s policy for final verification. Measurements stay in your browser.
