7kg, 8kg, 10kg or no published weight
Some airlines weigh cabin bags at the gate; others focus on size. Low-cost carriers may include only a small under-seat item.
Baggage allowances
Which luggage rule will sting?
Compare carry-on, checked bags, fare families and status before you buy. The same airline can be generous in business class, harsh on basic economy and totally different on another route.

Sort bags by weight, pieces and cabin.
Airline luggage rules are inconsistent: fare family, route, cabin, frequent-flyer tier and even overhead locker access can change the answer.

Deep links
Can booking sites sort by generosity?
Expedia deeplinks can prefill a flight search, but the documented flight listing sort is price/duration style rather than baggage generosity. Kiwi/Tequila is closer because results can expose bag limits, bag prices and a booking deep link. The useful version is to score the baggage rules here first, then send the user onward.
Best approach: rank by total trip cost with bags included: base fare + first checked bag + cabin bag/overhead fee + excess risk. Then deep-link the selected offer or airline search.
How to think about it
Flights Luggage essentials.
Piece concept vs weight concept
The US and many long-haul routes use bag counts, while many international airlines use total kilograms.
Economy, premium, business, first
Premium cabins often add pieces or weight, but fare type and route still matters.
Gold, elite and card benefits
Frequent-flyer status can add allowance, but partner-airline and codeshare rules can be awkward.
Booking notes
Why this needs checking.
- IATA explains that baggage rules vary by carrier and itinerary, with checked baggage handled under airline tariff and ticket conditions.
- Low-cost carriers increasingly split small under-seat bags from paid overhead cabin bags or priority boarding.
- Full-service airlines often change allowance by fare family, cabin and frequent-flyer status.
- Business and first class can mean two cabin pieces or extra checked bags, but route-specific rules still win.
