Airlines can be classified into two categories. Those, traditional (Air France, KLM, Lufthansa, British Airways, Singapore Airlines, Emirates, Qatar Airways, American, Delta, United, etc.), which adhere to IATA, the international association of air carriers, and respect common rules .
And the others… Often low cost. In this other category, the authorized dimensions of cabin baggage can then vary and put you in uncomfortable situations and in most cases expensive. Thus, traveling on the outward journey with a low-cost vehicle and returning with another does not guarantee that cabin baggage will be accepted free of charge on both journeys.
On the IATA side, a standard governs the dimensions of cabin baggage in economy class and, English language obliges, "carry-on baggage should have maximum length of 22 in (56 cm), width of 18 in (45 cm) and depth of 10 in (25 cm)". These dimensions include handles, pockets and wheels. The weight of the baggage is left to the discretion of the company and may be limited to 5 kg. In practice, it is often 10 to 15 kg.
60% more bagsAircraft and airlines are working together to accept more carry-on bags. Air France is equipping its latest aircraft delivered (A350, A220 and renovated A320) with more spacious luggage compartments supplied by Safran. The ECOS "Efficient Cabin Open Space" system offers up to 60% more storage capacity compared to currently available luggage compartments. This by storing the regulatory suitcases on the edge with the wheels towards the bottom. On an A320, this translates to 166 bags compared to 104 previously. This corresponds to a high expectation of passengers and, at the same time, these new safes speed up boarding and disembarking and reduce the risk of delays (and financial loss).
