So I almost missed a flight. (I have missed flights before, so this is a real near miss)
I was in HKG and enjoying the Pier F before taking a QF flight. Used the nap area and had a good meal before I decided to have a shower before I went back to the low number gates to board. I was going to visit the QF Lounge too, but there just wasn't time.
I had set a countdown timer to show how much time I had before my flight started boarding (which I set to 45 min before departure). My clock was still showing a good hour left, so plenty of time for a shower then walk over. I also had no alerts on the QF app, so also honky dory. Then I decided to check TripWaffle, just off hand. I looked at the flight time.
The departure time was supposed to be now. My countdown was about 1 hour in excess. I had set it up wrong (or the app had adjusted it wrongly).
Shower had to be abandoned as I quickly redressed. I pleaded with the reception agent to call the gate to tell them I was coming, even though it wasn't a CX flight. The agent was very nice - they didn't have to help me and there may have well been nothing they could do. He checked the flight status, and it wasn't boarding yet. Surprised, but in any case he told me to hot foot it.
That I did. I made the flight with nominally plenty of time to spare, but hot footing it all across the main terminal from gate 66 to gate 6 was something else. To add a bit of insult, the already-delayed flight (which allowed me to make it) ended up being significantly delayed.
