I have to go to a meeting in the United States in October, and I was pleasantly surprised about some of the tools to make travel a little easier. Air NZ have the great mpass app for the iPhone (and any java capable phone like Blackberry), visit www.airnz.mobi to get it and to quickly lookup deals, flight timetables and arrivals / departures.
Another innovation was how much travel you can book online, including multistop, and returning from a different city. As an example, I always prefer to fly into San Francisco as it is an easier airport to arrive and transit, whereas the Koru lounge at Los Angeles is just like home so always prefer to depart from there. The only feature missing from the multistop booking tool is that arranging travel in different classes on parts of your journey is still a manual process. Fortunately we have a great travel agent in Paula Ward at the Air NZ Travelcentre Hamilton.
SPG (Starwood Preferred Guest) have a nice app for tracking your accommodation plans, making bookings (great for when you forget details like the address of the hotel), for the endless forms and pre flight online paperwork.
