here is the statement in the assignment:
=> Create either a Sequence or Collaboration diagram for each use case provided.
What confused me is that there're four "Detailed Use Cases" provided in the assignment, however there're three extra Use Cases in the "Use Case Diagram", namely. "Create profile", "log in", "View frequent Flyer miles"
Shall I provide sequence diagram for those three extra use case?
P.S. Several days ago, Priya answered this question saying that I have to provide sequence diagram for all the use case. However I saw somewhere another version of the answer: only need to provide 4 sequence diagram for those detailed use case. Which one is correct? Please enlight me. Thanks a lot.

You are required to submit at least one diagram per UC. But as you have discovered, some of the UCs are repeated and therefore you will end up with a couple of "reusable" sequence diagrams.
You can model these common sequence diagrams separately and use the <<invokes>> stereotype to show their usage in the context of other UC realizations.
