You put your finger on what some are trying to do on this forum: interpreting Scripture in the light of their dogmatic presumption of a secret rapture, a novel idea unknown in Church history until the 19th century.
Yes it is his second coming. We need to stop using this term rapture. We are caught to him in the air as he returns to earth.
Yes, believers being "caught up together with Him in the air" is part of the great end-time event known as the Second Coming of Christ, and has been so understood throughout Church history.

The first people we know of that had been told there had already been a secret rapture were the Thessalonians.
Paul explained to them that there had to be a moral/spiritual “falling away” first, and the man of sin must also first be revealed, before anyone would be raptured.
Since those things stand in the way, Yeshua’s return to gather us is not imminent.

The actual second coming is 15 days after his gathering of his bride. That is represented in the 15 days between Yom Teruah, and Succot.
That is why he gave us his feasts, or “Appointed Times.” So that we would know his plan well in advance, and be ready. That is what Rev. 3:3 is pointing out.
For those that refuse to watch (IOW keep his appointed times) he will come in a complete surprise, “as a thief.”
