Terrible, dont even try this app. The developers will continue making updates however it's been a couple months, bonus miles, rewards, and even just collecting miles no longer work on the app so it's just taking up space on my phone. It used to work great, rewards werent the best but I did a lot of the charity rewards so it was fine. However this app is now trash as it doesnt work. I wouldnt even suggest this app to my enemies because it's that useless.
