I have been travelling quite a lot in the last month or so: even more than usual. TripTracker has been an absolute boon. If you are flying with different airlines and using properties from one or more hotel groups, it aggregates the whole lot into one reliable chronological agenda. It can even include car hire information. Simply enter your frequent flyer or loyalty account details for all providers and its agenda will pull all your travel information from their databases. It updates flight information like gate numbers and anticipated delays in real time, often sooner than they appear on airport displays. It even notifies you when your loyalty points have been updated and shows your current balances. Brilliant! http://www.pageonce.com/travel/iphone
