How to write an intinerary email that Gmail will recognize I want to email myself some flight details. How can I write the email so that Gmail will recognize the flights and make an auto event? Or, how do I make Inbox recognize it as a travel category email?

I understand that it might not be possible. Even when I receive itineraries straight from the airline, it normally doesn't recognize them anyway! Irritating that this feature is so half-baked.
What I've done in the past (you're not alone in this want!) is take other emails that I've gotten from other flights and replaced all the information with my new flight that I wish to track. Make sure you hit the most important parts


Itinerary number
Confirmation code
Flight numbers
Incoming/outgoing airports
All flight times


Once I filled in all my new information, I just forwarded myself that email and Gmail picked it up and even pushed the info into Google Now!

Pretty handy.
