Today while traveling back to my home, my scheduled flight was delayed and there was a high probability I would miss my connecting flight. As I was checking in, I saw a flight leaving in 20 minutes and wondered if I could run to the gate and see if I could get on this earlier flight going to the same destination. As I checked my luggage in, the agent asked if I had any lithium batteries in my bag. I said, “No,” as I wanted to make it to the service counter to see if I could jump on the earlier flight.
