You do if the rapture occurs seven years prior.
In point of fact, there are multiple serious conflicts with the events listed in this op and the long-held orthodox view of imminence (Jesus can return at any time). If the separated rapture has to occur first, then Jesus cannot come at any time. Jesus cannot come prior to the rapture. Jesus' second coming cannot occur until he first "comes for his own in the air" (as the op words it). Jesus' second coming cannot occur until the tribulation comes (and goes). Dispensationalists also variously say Israel must recapture all of the land God promised, build another temple, reinstitute the Mosaic Law, re-establish the Levitical priesthood, and reconstitute animal sacrifices. If any of those events is taught to occur prior to the second coming then 1) some means of knowing when he will return is established in contradiction of the premise no one will know the day or hour, and 2) the doctrine of imminence is contradicted.
The premise of a rapture event separated from second coming is not merely something that cannot be supported by Matthew 24:37-38, it also makes a mess of imminence. No one can rationally say seven years will occur between the rapture and the second coming and also say no one knows when the second coming will occur.
It will occur seven years after the rapture. Every person left behind can mark it on their calendar.
It is completely irrational but, then again, there is a lot that Dispensational Premillennialism teaches that is irrational. It teaches folks to use Matthew 24:37-38 as a text supporting the rapture when the surrounding verses preclude that interpretation.
