Landing in good weather is not particularly difficult. What's difficult is handling error conditions: the landing gear won't go down, an engine has failed, some instruments are out or misbehaving. Landing the airliner, safely, under those conditions require critical thinking, good flying skills, and practice. If you are planning on only taking one flight, you don't need to be good at this stuff, because it's unlikely that you will encounter any problems on that particular flight.

(Lots of people have died because of inadequate training in these areas. Eastern Flight 401 is a good example: http://en.wikipedia.org/wiki/Eastern_Air_Lines_Flight_401. The crew was so busy debugging a faulty light bulb that they forgot to fly the plane. It crashed into a swamp.)
