Guilty 🫣! For some reason, a few months ago, I thought a flight (can't remember which, perhaps AUS?) was from B gates, so headed straight to the B lounge and spent an hour in there. Realised it was an A gate departure, jumped on the transit after confirming with two workers sitting in the waiting area you can 'go back to A via transit'. Another worker with a wheelchair was also heading back to A via transit and asked what I was doing. Told him, he said I'd have to go back via connections.

To be fair, this was pretty swift. I went to connections, explained, let me straight through after scanning passport. Didn't realise you had to go through second a second time, but that was swift too. So through connections and security within about 15-20 minutes. It was a quiet area and no wait.

Although it was a bit of hassle, arguably it might have ended up being quicker than walking slowly between B and A!
