Samsung phone Calendar

[Galaxy01]

Re my coming holiday trip. Made my online bookings, Singapore Airlines, Cathay Pacific and return trip via Air New Zealand.
My Samsung phone Calendar automatically entered the flight details for SIA and CX flights soon after the email came through but not Air NZ. Of course, I can manually add in to the Calendar,  no big deal. 

Just out of curiosity, I am wondering why the Calendar doesn't pick up the information from Air NZ's email?

Any comments?

Cheers

Only A guess, maybe the other airlines are somehow linked to the Samsung App and Air NZ isnt. Dont know If you had the Air NZ App installed it "May" pick up but with things these days some apps allow cross access some dont. ???
