Yes. The Trips IQ app keeps your trips on your device, so you can pull up your itinerary even with no cell service or Wi-Fi — on a plane, or right after you land somewhere new.

• Trip details — flights, hotels, confirmation numbers, addresses, notes, and your checklist are all available offline.
• Your files — boarding passes, tickets, and badge PDFs are downloaded ahead of time for trips that are coming up or underway, so they open at the gate.
• Automatic — there's nothing to tap. Whenever the app has a connection, it quietly saves your upcoming trips for offline use.

When you're offline, you'll see a small Offline note telling you when your trips last synced. Changes (adding items, checking things off) need a connection — they'll be available again as soon as you're back online.
