Get random error "communication was not successful", makes me put in the same information 3 times, despite being on a reliable connection. Tries to communicate aggressively with known tracking and data mining servers, and refuses to work on a network with restrictions connecting to said servers, despite being not reliant on them for core functionality. Bad app that is required for travel, will uninstall ASAP.

I love this app. so easy to book flights, and even use my mileage to book or purchase items from the Mileage Mall (delivery to Korea only). Would like to see Korean Air expand the Mall to other countries though. Overall, very satisfied with this app.
