Apple's submission to the US Patent and Trademark Office hints at the full scope of iTravel.
The app will run on iPhone and iPads as well as desktop and notebook Macs.
The first step for iTravel is to help travellers find and book flights.
Apple's reservations engine will span from flights and hotels to car hire and cruises.
And of course, Apple will be in line for a cut of every booking you make.
iTravel goes beyond bookings, and will be a complete itinerary app from start to finish.
At the airport you can find food and shopping outlets or just head for the lounge.
The digital check-in system would rely on wireless technology built into a future iPhone.
Apple also hopes to use the iPhone to confirm your identify and even act as an e-passport.
RFID bag tagging at self-service luggage drops is another trick up iTravel's sleeve.
As with the Qantas Next-Gen Check-in system, your iPhone would sync your reservation to your checked bags.
A quick swipe of your iPhone at the boarding gate and you're good to go.
Some airlines could even let you use your iPhone to control the in-flight entertainment system.
On arrival, iTravel's city guide features kick in. These will pose a serious threat to third-party travel apps.
iTravel also stakes out the hotel scene.
The 'pre-arrival' mode for hotels includes remote check-in on your way from the airport.
At the hotel, your iPhone or any other iTravel device becomes a digital concierge...
... as well as an in-room controller for entertainment, air conditioning, lighting and more.
By hooking into the hotel's own IT systems you can check out the local attractions or book in-hotel facilities.
iTravel can also help ensure you get any rewards points or frequent flyer miles from your hotel stay.
Tapping into the luxe ocean liner market, Apple's iTravel offers a similar start-to-finish suite of tools.
This includes a GPS-enabled map of the decks, your personal activity schedule and social networking to keep in touch with your on-board 'buddies'.
