Not sure where this belongs because there are several programs. For an upcoming work trip to the EU (trip booked by boss - no input from me on anything except hotel in Paris) I have the following flights: Day 1/Day 2 overnight flight (Flt 1) JFK to CDG on AA Business Class, US hotel chain, Day 3 (Flt 2) CDG to FRA on AF Premium Economy, Day 3 and Day 4 hotel is an EU chain I'm not familiar with, Day 5 (Flt 3) FRA to VCE on LH Economy, hotel TBD for Day 5 and Day 6, Day 7 (Flt 8 & 9) VCE LHR JFK on BA Business Class.

I have no status on AA, ~22K in the acct (AA pulled out of primary airport 4+ yrs ago - been dumping 1 activity a yr into acct to keep balance active, but flies into airports 2+ hrs away). I am Silver on UA and Delta. Planning on using Delta for AF flight, UA for LH flight and US hotel chain miles (promo going on now), and AA for AA/BA flts. The hotel in FRA (Lindner) does not appear to be affiliated with any of the programs I belong to, but is part of LH Miles and More. I'm toying with joining LH or other airline program to capture the miles at the hotel, but not sure which to use.

Should I stick with the plan I have above or is there a way to Max miles/status that I'm overlooking? Since this is a forced march, I want to make the most of it, so I can sit far away from boss (not a loyalty gal) on any future flights. Most flights are domestic and are SkyTeam or StarAlliance. All EU flights to date have been SkyTeam or *A, but EU travel to go up this year. Cost will drive the flts selected (permitted Business class on long haul int'l).
