The Future Continuous is used for an activity that happens in a future period of time. For example:
- This week I'm working in Boston, but next week I'll be working in Los Angeles.
- Where will you be staying? I'll be staying at the Warwick Hotel.

The Future Continuous is made with the will + the verb "to be" + the -ing form. For example:
- I will be arriving at 4.00.
- They will be staying for a few days.
- She will be going to America.

Negatives add not, for example:
- I won't be arriving at 4.00.
- We won't be staying for a few days.
- She won't be going to America.
- Will you be studying late tonight?

Questions invert will and the subject, for example:
- Will you be arriving at 4.00?
- Will they be staying for a few days?
- Will she be going to America?

The Future Continuous is used for an activity that happens during a future period of time. For example:
- I'll be having a meeting from 3.00 to 4.00
- She'll be eating dinner with her friends this evening.

The Future Continuous is also used for an activity that happens around a certain time. For example:
- I'll be arriving at 7.00. (I'll be arriving around the time of 7.00)
- I'll be seeing you at Mike's birthday party.
- What time will you be leaving? I'll be leaving at 10.00. (I can't leave at exactly 10.00, but the process of leaving happens around 10.00.)

The Future Continuous is sometimes used for formal offers, for example:
- "Will you be needing a cab home, sir?"

The Future Continuous is often used to check information, for example:
- Will you be be having lunch with us?
Compare with the Future Simple, which sounds more like an offer, for example:
- Will you have lunch with us?

The Future Continuous is also used to make sympathetic predictions about people's feelings, for example:
- You'll be feeling hungry after a hard day's work.
- You'll be needing some rest before you go.
