1) App insists on refreshing of you have to switch out to view your calendar for example.
2) NO PRICING
3) After all of your itinerary is in place - THERE IS NO WAY TO PURCHASE TICKETS??!!! You select the buy ticket option which (wait for i....t /- as the drumroll builds) launches a browser where you have to start all over from scratch??!!!
(Really really bad - youd think the least they could do (if this is the only option) would be populate the data you entered from the app. Nope.
Non-starters. Huge waste of time.
