That is why you carry 15min extra fuel. The idea is you commit to destination before you leave! so at destination you should have just under an hours fuel, penty to sort any problem out and land at a big airport with 6 runways!! not a big deal it's just mindset. If you like you are diverting to your destination..........
The what ifs are dealt with before you leave like weather and airport equipment. And if you are not sure or don't fancy it then it's simple you carry Alt fuel.
As I said our company is fighting for survival and if knowing how to operate well helps reduce costs then it's fine by me.
