What tense do I use in the following statement?

Using the verb to call

Answer 1

Hey mate..

Here's your answer..

Since for the expressions like..

1)By evening
2)Until midnight
3)Before noon
4)By the time you reach

We use Future perfect..

So the correct answer have to be..

➡will have called

Thus the sentence goes like this..

⭐ By the time Cynthia books the flight to Iceland, she "will have called" her sister about the trip.
