2.1.- Future continuous and future perfect.

If you want to describe an action that will be in progress at a specific time in the future, you use the future continuous:
- On July 16 at 8 a.m., Mr. and Mrs. Steward will be flying to Canada.
  Look at the example and think about the form of the future continuous:
  Will + be + -ing form
  
  Negative form: Won’t (will not) + be + -ing form
- On July 16 at 8 a.m., they won’t be flying to Vancouver.
  Interrogative form: (Wh-) Will + Subject + be + -ing form?
- Where will they be departing from?
On the contrary, if you want to say that an action will be completed at a particular time in the future, the Future Perfect is used:
- By July 30th, Mr. and Mrs. Steward will have visited Canada.
  As you can see from the example the future perfect is formed as follows:
  Will + have + past participle
  Negative form: Won’t (will not) + have + past participle
- By July 30th, they won’t have arrived in London.
  Interrogative form: (Wh-) Will + subject + have + past participle?
- Will they have arrived by midnight?
