Answer: The correct answer to this question is “are you flying to LA tomorrow?
Step-by-step explanation:
This is simply an understanding of proper use of the appropriate verb tenses in the required situation.
In this case, we look at the context of the question, which is asking about an event you expect may happen in the “future”. The future perfect tense “flying” is the one to obey the rule of concord in this case (that is the correct construction of the sentence”.
On the other hand, it will be appropriate to use the other option in a sentence such as this “do you fly everyday” or “do you fly to Los Angeles”. This will depict an action that is continuous.
I hope this helps?
I’d be willing to give further explanation if necessary.
