Thanks re VariFlight. Am trying it now. Wish it had TripIt integration.

So far I find Flight Update Pro to be the best and AITA to be the most useless.

But still bemoan the loss of FTPro. I still use it to keep track of flights (i.e., to answer friend's questions of "when are you leaving for ----"). But its utility decreases to zero as you get close to flight time. The applicable flight "greys out" about a day before takeoff and becomes useless.
