I've been late a lot on UA (44%) or just not made it at all (6%). My bags have been lost or delayed 9 times out of the 12 times I have ever checked them (I rarely check). Once it was a Beretta shotgun they lost for 12 days. It's pretty bad to loose a firearm that is supposed to be handled with the utmost of care, far above routine care, you have to file special paperwork with it. That was when I had zero confidence in checked luggage with UA.
