I've only experienced two go-arounds as SLF - handled very differently.
1. A long time ago - when Go were still alive. Landing at Bristol in strong winds we were at or about touch down when the plane pitched up. Pilot came on to say the ILS had failed, and as they were relying on it, they had gone around. Said they were turning it on at the other end of the runway and we would try from there. I suspect something may be have been over-simplified, but we did indeed land from the opposite direction and it was very windy....
2. Aer Lingus - less of a go-around, more of a missed approach I suppose. Wheels came down, wheels went up. We were in the air for another 15 minutes before landing. No-one up front bothered to tell us mere mortals what was happening. a 20 second PA to offer some reason/reassurance would have been nice.
