Several sources I have suggest that the Olivet discourse have nothing to do with the rapture just the second coming of the Lord at the end of the 7 years of tribulation.
Interpretive Flaws in the Olivet Discourse | The Master's Seminary
No doubt there are preferences in that direction so that is why I highlighted certain phrases in Matt 24 that make it crystal clear.
Matt 24
29 “But
immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from the sky, and the powers of the heavens will be shaken. 30 And then t
he sign of the Son of Man will appear in the sky, and then
all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of the sky with power and great glory. 31 And He will send forth
His angels with a great trumpet blast, and they will gather together His elect from the four winds, from one end of the sky to the other.
that fits 1 Thess 4:13-18 perfectly
1 Thess 4:13-18
13 But we do not want you to be uninformed, brothers
and sisters, about those who are asleep, so that you will not grieve as indeed the rest
of mankind do, who have no hope. 14 For if we believe that Jesus died and rose
from the dead, so also God will bring with Him those who have fallen asleep through Jesus. 15 For we say this to you by the word of the Lord, that we who are alive and remain
until the coming of the Lord will not precede those who have fallen asleep. 16 For the Lord Himself will
descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first. 17 Then we who are alive, who remain, will be caught up together with them in the clouds to
meet the Lord in the air, and so we will always be with the Lord. 18 Therefore, comfort one another with these words.
Matt 24 - "will appear in the sky" --> 1 Thess 4 "meet the Lord in the air"
Matt 24 - coming in the clouds of the sky --> 1 Tthess 4 "will descend from heaven"
Matt 24 - "The trumpet of God" --> 1 Thess 4 "a great trumpet blast"
Matt 24 - "gather the elect... from one end of the sky to the other" -- 1 Thess 4 "meet the Lord in the air"
Matt 24 - "Son of man coming" ---> 1 Thess 4 "coming of the Lord"
Matt 24 does not explain how it is that the "elect are in the sky" when the angels come to gather them -- 1 Thess 4 explains how that happens - and it is at the 2nd coming described in Rev 19.
