As I am traveling on Air Canada on my jaunt to John's wedding, I had assumed that getting Leonardo through security would be simpler than my last trip with WestJet (please see a previous entry, link to follow when I get to a proper computer.) More fool, I.
When I went to the Air Canada baggage drop-off (regular sized), I was told that something wasn't working at the oversized drop-off and I would have to go to the "WestJet" oversized drop-off point. As the box didn't fit in that place's scanner, I had a repeat performance of last time's experience of taking Leonardo under escort to the bigger Air Canada scanner and then back to the WestJet drop-off point!
Hmm, I hope this doesn't affect my chances of meeting Leonardo in Vancouver! The evidence suggests a full flight. Thankfully, I remembered to put Margo's address on the box.
