Hi all!

I have a quite unique situation and would love some advice given my mileage balances, travel preferences, and (potential) home location.

Current Statuses

• United - Platinum for life due to gifting. If i want to hit 1k, i must requalify from 0 every year.
• American - Status matched platinum until 2019 (currently my next few flights are on AA)
• Delta - No Status

Current Mileage Balances

• United - 10k (but have 400k UR)
• American - 270k
• Delta - 150k
• AMEX MR - 250k / Citi TYP - 300k

Mileage Goals / Home Locations

• Home location: will be changing over the next year but will rotate between SFO and NYC
• Main mileage redemptions: Europe / Asia in J Class

Upcoming Travel Plans

I'll be travelling quite a bit over the next year for work. I have 8 transcon RT paid tickets in J class (SFO to JFK), with some further travel after that.

Give my existing statuses and goals, could anyone advise what you would do? A part of me wants to increase my delta balances to diversify however it is also tempting to push towards a road warrior status at AA or potentially United (for the GPUs)

Thanks in advance all!
