The app now will not allow to find any flights on certain dates, randomly... Only work around is to uninstall the app (which of course deletes all the trips you might have saved) and reinstall. Then you have to put in all the flights again. Quite a chore.
The old version that I run on my iPad works just fine.
So... Mobiata, thanks for a really lousy upgrade...
