I believe, you and many other people have been "led down the primrose lane" (should believe a lie), concerning this whole "concept of rapture, or of being seized, or snatched away (from the earth/world)", as well as how "into the air", is translated, or more precisely "mistranslated."
Let's start out with "into the air" first.
There are very many instances in the Bible, both O.T., and N.T., in "the explaining of things spiritual", when "human language/s" no matter when they were written, during the passing of years, decades, centuries, millennia, just haven't the capability of rendering correctly, "Spiritual Happenings!"
This is "by consequential design!" Ever since "the fall of Adam." When God's Spirit, would no longer "strive" with "man's spirit", when there "really" was NO NEED at all in the PRESERVING OF! As God's Spirit was "with" man's spirit! And, there really was not the "division, by means of apostasy, or falling away", against flesh FROM Spirit.
A more PRECISE "rendering" of "in the air", in this case, would be "in/with the spirit AND MIND of man!" And, NOT the "contextual literalistic" interpretation, of "in the clouds" "in the air!"
Now, this "snatching" or "seizing?" Would not be like when someone accepts Christ as their Lord and Savior. But, more like Jesus' "thief in the night" analogy of "rapture!" Inasmuch as one is in no wise EXPECTING IT!
Or? More precisely, not "ready" or prepared for the "how", let alone the "when!"
Kinda like: "I had NO IDEA, it was gonna happen "like THAT!" (UTTER BEWILDERMENT)
Isaiah 28
18 And (WHEN) your covenant with death shall be disannulled, and (WHEN) your agreement with hell shall not stand; when ((HOW) the overflowing scourge (WHAT) shall pass through, then (HOW) ye shall be trodden down by it.
19 From the time that it goeth forth it shall take you: for morning by morning shall it pass over, by day and by night: and it shall be a vexation only to understand the report. (UTTER BEWILDERMENT)
20 (When THIS "realization" HITS ya) For the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it. (to EVERYONE....in "their" season!)
This is more like what "rapture" be "like":
Revelation 20
6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
