Lets say at T-7 days you request and upgrade, 23 hours after that you have another flight and then 20 beyond that you have another flight.

When you request the initial upgrade this can be only for the first leg.

You can not select the other for another 20 hours and then the third for another 20 hours.

If 2 days after the initial request I then request the two other flights the group then changes from individual selections to one one request and drops the number for total e credits required.

My question is though because the three are being merge at T-5 will it re-set the initial flight that was requested at T-7?

I dont want to go request the two other flights now as it will be T-4 and the first flight then perhaps is reordered to put me on the list in the middle? Will the original request remain at the top of the list?
