Been involved in 4 go arounds, all on TCX757s in May 2006.
Fog at Zakynthos meant 2 aborted approaches and a diversion to Athens. Once on the ground at Athens, we refuelled, waited an hour, then had another attempt.
This time thick, low cloud cover meant the pilot couldnt see the runway, and the risk of getting below the clouds and not being lined up was too great, so after a couple of attempts, it was back to Athens again. On the final approach, there were a few tears and tantrums from pax, including some appalling comments from folk near the front, who were more concerned about losing a few hours of their holiday then their lives....
Full marks to the crew for trying before their hours ran out, and we were kept well informed.
