This should not be the case for any modern airline; too many accidents were caused by exactly this problem in the past.

However, I don't doubt shady operations might be doing this(more so if they aren't carrying passengers). They won't be around for long if they are caught doing this kind of nonsense and it causes an incident (or accident in this case).

Today there may be some rules (more than X go arounds because of weather, you have to divert, etc).
