After being anti-portal for a while, the lack of good transfer partners that aren't also available with Amex/Citi made me start using it a lot more in 2019 both for flights and also experiences/tours. I'll only use the portal when it matches what I can book on Google flights/direct with the airline though, which unfortunately means I've found little use for it in Europe, but anything US domestic or ex-US seems to price out the same.

2020 will see more transfers to partners since I depleted my Avios and Hyatt balances last year.
