The limits vary per airline and depend on the class, elite status, ticket type, flight origin, and destination.
The International Air Transport Association (IATA) has released recommendations for limits on checked baggage and carry-on luggage.
The recommendations for checked baggage are: advised maximum weight 23 kg (50.7 lbs), weight limit 32 kg (70.6 lbs), advised maximum size 158 cm (62.2 in) length + width + height, limit 203 cm (nearly 80 in).
The total weight varies per airline and depends on the class, elite status, type of ticket, flight origin, and destination.
Different airline websites will normally explicitly state their baggage fee policy and limits.
