Changing a sentence from ‘would + Infinitive’ to ‘would have + Past Participle’ (In other words, from 2nd to 3rd Conditional) is to pass a Hypothetical Sentence from Present to Past:
I would(n’t) visit my uncle in Alaska → I would(n’t) have visited my uncle in Alaska
You will have to know how to use the rest of the sentence:
If the company gave me my Christmas bonus, I would(n’t) visit my uncle in Alaska → If the company had given me my Christmas bonus, I would(n’t) have visited my uncle in Alaska.
Third Conditional: Would
