Why did my flight descend for landing then suddenly climb steeply and turn sharply?
According to data recorded on Flightradar24 and the Planefinder App, that particular flight did not go around; however the turn to final approach was flown at lower altitude than some other flights that day (this seems different but not necessarily uncommon or abnormal, and happened for unknown reasons that cannot be inferred from the data).
