bumpy landing, and we had to go around at bhx twice because of traffic
Rest assured that TCX crews are trained and tested to exactly the same standards as every other UK airline. For what it's worth, the TCX training department is renowned as being very, very good.
Although passengers like nice, smooth landings, what's more important for the pilots is landing at the right point on the runway at the right speed (to make best use of the space available, especially on shorter runways) - sometimes this means a slightly heavier landing in the process. The aircraft are designed to take this and more so, again, try not to be too alarmed!
Go-arounds, although relatively rare, are considered a standard, "normal" manoeuvre by crews and trainers - one of the main reasons this way of thinking is instilled is so that there is no hesitation at performing one if things are not exactly as the crew would like. I'm sure you'd agree with this philosophy! Having said that, they can feel quite dynamic to passengers in the back so it's understandable that people are slightly wary of them. They also often come with little warning, which can't help. Lastly, don't be worried if you hear nothing from the flightdeck for the first few minutes after a go-around - they are busy climbing the aircraft away and following the missed approach procedure before coming up with their next move.
