I just got my 1k package today.
Interesting choices of cities if you ask me, not United's most frequented destinations.
AMS: Tons of flights, from EWR, ORD, SFO, IAH and IAD, pretty robust schedule!
SIN: Two flights per day, both from SFO.
GIG: A only one flight per day, from IAH. UA has a much more robust presence in São Paulo.
AKL: Currently daily, but come 30 Mar, only three flights per week, from SFO.
Are these supposed to be cities that they're trying to drum up interest in?
