I'm considering using carry-on rather than checked luggage for a couple of upcoming trips. I'd much prefer to check it, but obviously concerned about all the problems over the past few months. I'm researching online, hoping to find if the situation is improving, but I'm only finding old data from up to early Summer when things were really a mess. Does anyone have recent information or experience with this? And if your luggage was lost, how soon was is returned to you?
