In pre-tribulation pre-millennialism, will those who have died before the millennium return to earth? Let's just say God raptures his church in the next few years and we are alive to experience it. We survive the 7 remaining years. Then the "Glorious Appearance" happens and God sets up his 1000 year reign on Earth.

Will our loved ones come down from Heaven to live on Earth with us? Or will we have to live 1000 years with God on Earth before returning to Heaven to see our loved ones? How does that work? Will Heaven on Earth and Heaven become one so that way we will all be able to live together? Or will (Heaven on Earth) and (Heaven) still be two separate places until God takes us up to heaven after his 1000 year reign?
According to Theopedia, in classical dispensationalism men, angels and Christ will return to the earth. 


  Classic dispensationalists (ala C. I. Scofield and Lewis Sperry Chafer) are pre-tribulationists and believe that the second coming will be in two stages separated by a 7-year period of tribulation. At the first he will return in the air to rescue those who are Christians at that time (the rapture). Then follows a seven-year period of suffering in which the Antichrist will conquer the world and kill those who refuse to worship him. At the end of the seven years, the final witness will go out before men and angels and Christ will return to the earth. He will defeat the Antichrist, and rescue the Jews and those who have converted to Christianity during the tribulation period.

Wikipedia says the same thing.


  Dispensational premillennialism[64] generally holds that Israel and the Church are distinct entities.[65] It also widely holds to the pretribulational return of Christ, which believes that Jesus will return to take up Christians into heaven by means of a rapture immediately before a seven-year worldwide tribulation. This will be followed by an additional return of Christ with his saints (though there are post tribulation dispensationalists, such as Robert Gundry).
