1. This was way before TSA. My DH & I were going to Trinidad, and one of our checked bags had a little padlock on it. My FIL drove us to the airport and, at the last minute, my DH decided to give his dad his car keys (don't need them in Trinidad, eh?). Well, the key to the padlock was on that ring. Fortunately we didn't do any major damage to the bag by breaking into it at our destination.

2. Flight from Winnepeg to Churchill. Checked in, got our BPs, was directed to the gate. There was a line & ppl were boarding. It was a little early to board (perhaps 30-40 minutes, but some of these flights will leave early if all passengers are present). We get in line, get our boarding passes checked & ripped in half, and walk out on the tarmac to the plane & board it. We are not finding our seats, & while doing so, a guy with headphones on comes up behind us asking, "are you folks going to Churchill?" "Yes, we are. Why?" "Well, you're not going to get there on this plane because this flight is going to Saskatoon!" Now how the gate agent overlooked that is beyond me (and yes, the sign also had our flight & destination on it already). The gate agent got us some Scotch tape to put our boarding passes back together.
