I was in the *A lounge in ICN waiting for my connecting OZ flight back to HNL from TPE. I had a 3 hour layover. My flight was scheduled to take off at 8:00 pm and boarding started at 7:15 pm or so. Anyway, while I was sitting there, an OZ agent approached me and asked it I was flying to HNL. At my confirmation, she told me that I was late for boarding. I looked at my phone (still on airplane mode) and it showed 6:53 pm. I showed it to her and she told me it was actually 7:53 pm. Yikes!!! She got on her walkie talkie and escorted me down toward the gate (thank god it was just down the stairs and around the corner) and another gate agent escorted me the rest of the way. I boarded the plane and sat down at 7:58 pm. The plane doors closed and started moving within the next few of minutes. I'm still not sure what happened with my time but I was so lucky! Not sure if it made any difference but I was in Business class. This would have never happened if I was flying on an US airlines or probably any other western airline - I would have just missed my flight. The thing is, I had seen an agent walking through the lounge a little earlier but couldn't understand what she was saying so had just not paid any more attention.
