I have been reading about people wanting to trigger travel mode in app, and there are several issues with that.... so how about this:
Travel mode scheduling.
At my leisure, I can log on to server and say 'trigger travel mode on date/time' (ideally, multiple entries allowed!)
So, I book a flight, I enable travel mode in advance, and forget about it. No having to mess with computers at 4am as you get up bleary eyed to go to the airport.
As an option, I could also enter 'disable travel mode rules'.
The ultra paranoid would not have that, fearing they'd be detained until their vaults returned; but for most people, they could just have 'disable travel mode after X hours/days', 'when my phone has arrived within X miles of location', or similar.
Thus, you don't have to remember to enable on the day, and you don't have to be logging on to websites when actually on your travels, but those who want full control can still do it manually.
