Here is my booking proposal:

ATL - FRA - in LH Business
FRA - FCO - in LH First
FCO - BKK - in TG First

72,500 miles

There is no First available currently on the ATL - FRA leg.

Would it be possible to change to F later if it opened up?

If so, would a fee be involved?

I am an general member with UA MP if that matters.

I couldn't find anything here or on united.com that said specifically what the deal was in this case.

Secondly:

If I am able to find an open First seat on TG's direct FRA - BKK flight: It looks like no fee to change since origin and destination are still the same, correct?

Thanks guys (I am still learning!)
