Third here for TripIt - I've used it since 2009 and it has a very handy tracker that shows you all your flights and trip data (bit terrifying to see your total days away for 13 years...!). But very easy and can create a subscribed calendar feed so it appears automatically in whatever calendar you use (Apple for me)
