Probably just Citi IT being idiosyncratic but on their app my combined Premier/DC TYP account shows 0 points to transfer despite a healthy balance to any transfer partner. The full website however allows me to transfer the full balance to any partner including AA so at least for now no gate-keeping on the source of the points (for better and worse).
In other news was putting some finishing touches on a trip to Greenland and another to New Zealand the last few days and I was reminded of just how great the Prestige is. I found a hotel in NZ that I wanted that was cheaper on the Citi portal than elsewhere (by a nominal amount) saving me about $250 with fourth night free (also 10x on portal) and all the activities I booked in Greenland were coding as travel agencies (pretty common in my experience) so earned 5x on them. Please, please Citi let me keep this card.
