And never check baggage that won't completely close. As Irene can tell you, if your bag is too full to close, it's better to remove some items than to have the bag pop open when it's being loaded into the airplane.
Would you please be nice enough to clarify the bold written part to me?
In my opinion it means "a little open"
Am I right?
No. It means 'burst open' because it is overfull.
