Hi,
On my ipad it loads and remains upside down, forcing me to turn the ipad upside down. Also I find the instruction not to refresh due to high traffic make the app unattractive compared to the other apps I use ie Flightboard, Flightrack, Flightradar24 and Heathrow. All your left with is the ability to scan a ticket which is insufficient to make it worthwhile.
Sorry .... not for me.
