BA has a policy which states that after two missed attempts they would normally divert unless a significant improvement in the weather has happened or is likely to happen very shortly. We do not, as previously stated, take part in LAHSOs, and in the US you can be no9 on the Approach and still be cleared to land, it is the way the cousins do it. The last point of a go around is selection of reverse, only then are you committed to land. Pilots are taught early on to throw away a landing that isn’t right, it is the safest course of action, rarely would we consider continuing with a problem and KARFA outlines this well, a cargo fire would be a good example of continue with the approach. There is no shame in admitting you have cocked up a landing, safe pilots would do that, pressing on when things were not right would be dangerous. Bounce GAs are not common but a low level Ga can lead to a brush. A bounce can be better dealt with by Going around than attempting to continue with an already bad landing.
