In a trip I bought some items that cannot fit into my suitcase. My ticket allows for 1 more luggage.
Can I just buy a plastic garbage bag, fill it with clothes and check it in as luggage?
It is easier, faster and cheaper than buying a new suitcase.
I want to understand if there is any legal, safety or other restriction that prohibits using simple bags as luggage. Edit: More specifically I am thinking of checking-in multiple plastic bags, one inside the other, that are a very durable, yet not solid, "package" of clothes. Nothing fragile. The durability and "resistance to mechanical stress" of this package would be comparable with most bags. However I do understand that it would look like a "cheap" thing. (Because it is.) My intention is to avoid buying a suitcase to carry my laundry back home.
The plastic bags I have are the ones used to throw rubbish. It might sound silly bit they are durable and cost effective.
