I've only had one situation in WLG (from CHC) where it involved two go arounds before a successful landing. Dreaded the "guys we'll give this one more shot, otherwise we'll need to divert" but old mate came thru!

My worst experience was a CZ flight from CAN to HKT flight that involved 3 go arounds in HKT and then diverting to KUL as the alternative but also needed two go arounds there.
