There is no free baggage allowance, which means you can't check it.

General low-cost airlines, such as AirAsia, just don't have the free baggage allowance, so you need to buy the baggage allowance online in advance, and you also need to buy meals online. In addition, the amount of luggage can also be purchased at the airport when boarding, but the cost will be higher than that purchased online in advance.

in principle, you can take a bag and a 21-inch suitcase directly into the cabin, and the weight of the suitcase cannot exceed 7kg. So even if it's over 7kg, it's OK if you take it out and put it in your backpack.
