I use TripIt for travel planning, but I'm going to give the new Google Trips a try. It stores your travel plans offline, so you don't need to have a Wi-Fi or cellular connection to find directions or access your itinerary.
When I installed it, it scanned my gmail and did a great job of finding my upcoming flight, restaurant, and hotel reservations.
