Disappointing, not worth the upgrade to premium.
I paid for the upgrade yet the app is still quite restricted. Full information is not provided in all carriers. The app tells me my miles are expiring when in fact they are not. On many occasion regardless of booking a flight using your frequent flyer number, it is still not added automatically. They say to email the ticket, yet it still fails to read the flight details. Manually entering the flights is long and tedious, not recommended. There are other better apps available, Mileblaster, tripit....
